1 Introduction

1.1 Background

JBA has been appointed by the Office of Public Works (OPW) to provide environmental consultancy services in relation to statutory arterial drainage maintenance activities for 2019 - 2023 on the Lower River Shannon Arterial Drainage Maintenance Scheme. This includes preparing a Natura Impact Statement (NIS) report to present required information to the relevant Competent Authority (CA) to undertake Appropriate Assessment. Appropriate Assessment is required at this location due to the presence of the Lower River Shannon SAC within the Lower Shannon Arterial Drainage Maintenance Scheme.

The proposed works as part of the Lower Shannon Arterial Drainage Maintenance Scheme, furthermore, referred to as the "Scheme", are required as part of maintenance activities under the 1945 Arterial Drainage Act, and include the River Shannon and various tributaries along the Scheme channels. These channels are located within and adjacent to Askeaton Fen Complex SAC (002279), Ballyallia Lake SAC (000014), Ballycullinan Lake SAC (000016), Ballyogan Lough SAC (000019), Curraghchase Woods SAC (000174), Danes Hole, Poulnalecka SAC (000030), Dromore Woods and Loughs SAC (000032), East Burren Complex SAC (001926), Glen Bog SAC (001430), Lower River Shannon SAC (002165), Moyree River System SAC (000057), Pouladatig Cave SAC (000037), Poulnagordon Cave (Quin) SAC (000064), Tory Hill SAC (000439), River Shannon and River Fergus Estuaries SPA (004077), Ballyallia Lough SPA (004041) and Corofin Wetlands SPA 004220 Natura 2000 sites and therefore, requires Appropriate Assessment.

1.2 Legislative context

The Habitats Directive (Council Directive 92/43/EEC on the conservation of natural habitats and of wild fauna and flora) aims to maintain or restore the favourable conservation status of habitats and species of community interest across Europe. The requirements of these directives are transposed into Irish law through the European Communities (Birds and Natural Habitats) Regulations) 2011 (S.I. No. 477 of 2011).

Under the Directive a network of sites of nature conservation importance have been identified by each Member State as containing specified habitats or species requiring to be maintained or returned to favourable conservation status. In Ireland the network consists of Special Areas of Conservation (SACs) and SPAs, and also candidate sites, which form the Natura 2000 network.

Article 6(3) of the Habitats Directive requires that, in relation to European designated sites (i.e. SACs and SPAs that form the Natura 2000 network), "any plan or project not directly connected with or necessary to the management of the site but likely to have a significant effect thereon, either individually or in combination with other plans or projects, shall be subject to appropriate assessment of its implications for the site in view of the site's conservation objectives".

A competent authority (e.g. the OPW or Local Authority) can only agree to a plan or project after having determined that it will not adversely affect the integrity of the site concerned.

Under article 6(4) of the Directive, if adverse impacts are likely, and in the absence of alternative options, a plan or project must nevertheless proceed for imperative reasons of overriding public interest (IROPI), including social or economic reasons, a Member State is required to take all compensatory measures necessary to ensure the overall integrity of the Natura 2000 site. The European Commission have to be informed of any compensatory measures adopted, unless a priority habitat type or species is present and in which case an opinion from the European Commission is required beforehand (unless for human health or public safety reasons, or of benefit to the environment).

1.3 Appropriate Assessment Process

Guidance on the Appropriate Assessment (AA) process was produced by the European Commission in 2002, which was subsequently developed into guidance specifically for Ireland by the Department of Environment, Heritage and Local Government (DoEHLG) (2009). These guidance documents identify a staged approach to conducting an AA, as shown Figure 1-1.


Figure 1-1: The Appropriate Assessment Process (from: Appropriate Assessment of Plans and

Projects in Ireland - Guidance for Planning Authorities, DoEHLG, 2009)

1.3.1 Stage 1 - Screening for AA

The initial, screening stage of the Appropriate Assessment is to determine:

a. whether the proposed plan or project is directly connected with or necessary for the management of the European designated site for nature conservation

b. if it is likely to have a significant adverse effect on the European designated site, either individually or in combination with other plans or projects

For those sites where potential adverse impacts are identified, either alone or in combination with other plans or projects, further assessment is necessary to determine if the proposals will have an adverse impact on the integrity of a European designated site, in view of the sites conservation objectives (i.e. the process proceeds to Stage 2).

1.3.2 Stage 2 - AA

This stage requires a more in-depth evaluation of the plan or project, and the potential direct and indirect impacts of them on the integrity and interest features of the European designated site(s), alone and in-combination with other plans and projects, taking into account the site's structure, function and conservation objectives. Where required, mitigation or avoidance measures will be suggested.

The competent authority can only agree to the plan or project after having ascertained that it will not adversely affect the integrity of the site(s) concerned. If this cannot be determined, and where mitigation cannot be achieved, then alternative solutions will need to be considered (i.e. the process proceeds to Stage 3).

1.3.3 Stage 3 - Alternative Solutions

Where adverse impacts on the integrity of Natura 2000 sites are identified, and mitigation cannot be satisfactorily implemented, alternative ways of achieving the objectives of the plan or project that avoid adverse impacts need to be considered. If none can be found, the process proceeds to Stage 4.

1.3.4 Stage 4 - IROPI

Where adverse impacts of a plan or project on the integrity of Natura 2000 sites are identified and no alternative solutions exist, the plan will only be allowed to progress if imperative reasons of overriding public interest (IROPI) can be demonstrated. In this case compensatory measures will be required.

The process only proceeds through each of the four stages for certain plans or projects. For example, for a plan or project, not connected with management of a site, but where no likely significant impacts are identified, the process stops at stage 1. Throughout the process, the precautionary principle must be applied, so that any uncertainties do not result in adverse impacts on a site.

1.4 Methodology

1.4.2 Screening

The screening assessment conducted for these works has been undertaken in line with recommended guidance including that specifically produced for the OPW in 2014 (Ryan Hanley 2014b, 2014a). This methodology is based on source > pathway > receptor chain principles and involves assessing likely significant effects on Natura 2000 sites within the zone of influence of the proposed drainage maintenance in relation to three pathways:

1. Surface water

2. Land & air

3. Groundwater

The screening assessment involves assessing the impacts of drainage maintenance operations within the arterial drainage scheme, and its zone of influence, in relation to each of the three

http://www.npws.ie/


pathways individually. The results of each pathway are then combined in a concluding section to identify if/where likely significant effects may arise.


Figure 1-2: Screening assessment process

The screening process uses a combination of GIS analysis and qualitative assessment to identify which drainage maintenance activities, on which specific watercourses, are likely to have significant effects on the integrity of Natura 2000 sites.

The screening report, conducted by JBA ecologists in 2014, has been reviewed and updated as necessary for the production of this NIS.

1.4.3 Ecological surveys

To inform the Appropriate Assessment process, a number of assessments and ecological surveys have been conducted, including:

• An ecological desk-based assessment to collate information on designated sites and protected and notable species, including bird survey data from the waterbird survey programme and the Irish Wetland Bird Survey (I-WeBS).

• Multiple ecological walkover surveys were conducted of the channels within 100m of Natura 2000 sites in the Lower River Shannon Scheme, by multiple surveyors throughout August and September 2018.

• Ecological surveys were conducted in teams of two with a lead and assistant ecologist on each team. Lead ecologists included Tanya Slattery, Patricia Byrne, Steven Heathcote and Jennifer Pullen. Assistant ecologists included Catalina Herrera, Colm O'Leary, Malin Lundberg, William Mulville, Joe Freijser, Sarah King, Lea Nightingale and Mairi Gillis.

• Independent ecologists Michelle O'Neill and Domhnall Finch conducted ecological surveys on the Maigue Scheme and the North Shannon (Fergus).

The ecological walkover survey was carried out in general accordance with the methods outlined in the following documents;

• Heritage Council (2011). Best Practice Guidance for Habitat Survey and Mapping (Smith et al. 2011).

• Phase 1 Habitat Survey methodology (Joint Nature Conservation Committee (JNCC), 1990, revised 2003).

• Ecological Surveying Techniques for Protected Flora and Fauna during the Planning of National Road Schemes (NRA 2009).

• Fossitt, J. (2000). A Guide to Habitats in Ireland. The Heritage Council, Kilkenny (Fossitt 2000).

Aerial photographs and site maps assisted the habitat survey. Protected species, including mammals (e.g. Otter, Badger) and birds, were surveyed based upon sightings and signs of activity during the habitat survey and also by the identification of potentially suitable habitats. This included a preliminary assessment of features with suitability for roosting bats and recording of any non-native invasive species found. All evidence of protected habitats and species was recorded on a tablet using the bespoke JBA GISmapp application by JBA Ecologists where relevant. Independent ecologists recorded survey results on paper, which was later digitised by JBA Consulting. All information gathered was collated and provided to the OPW on a separate GIS database. The full ecological survey extent is shown in Appendix G.

The results of these surveys have informed this NIS where relevant.

1.4.4 Consultation

The findings of this assessment will be subject to consultation with the NPWS.

This report has been produced on currently available information, with the most up-to-date versions used. Where new, or updated, information becomes available the OPW will consider and review the findings of this assessment, if necessary.

1.4.5 Limitations and constraints

The conclusion of this report necessarily relies on some assumptions and it is inevitably subject to some limitations. Most of the assumptions and limitations would not affect the conclusion but the following points are recorded to ensure the basis of the assessment is clear:

• This NIS investigates the potential direct and indirect impacts of the proposed works upon relevant Natura 2000 sites and assesses the potential impacts for significance alone and in-combination with other plans and projects. This process takes into consideration the nature of the proposed works and the structure, function and conservation objectives of the relevant Natura 2000 sites. It gathers the required information from a variety of sources. Information used in this process may be subject to limitations and constraints that are not made clear in the various sources and these may then, impact upon the results of this report. Attempts are made to interpret potential constraints and limitations from relevant sources where possible. Where constraints and limitations within source data are evident, these are taken into consideration in the following assessment however, this does allow for a margin of error;

• Where significant adverse impacts are determined to potentially occur as a result of the works, a number of appropriate mitigation measures to be implemented during the Scheme are provided in order to prevent any significant adverse impacts as a result of the Scheme and proposed associated works. The conclusion of this report is based on the assumption that during the works, staff will be made aware of sensitive ecological features that may be present on site, will be competent to identify the presence of these features and will be aware of the mitigation measures and Environmental Procedures (EPs) to be followed as required in such circumstances;

• Ecological surveys attempt to characterise the habitats and their usage in the most accurate manner but are in effect only a snapshot in time. Surveyor bias, seasonality and health and safety restrictions may allow for variations in survey results. Therefore, ecological surveys may not always identify the presence of all sensitive ecological features that may be present;

• In all instances where constraints or limitations may impact the result the impact of the NIS, the precautionary principle is used.

• The description of activities, assessment and mitigation measures described in this report relate to the content of the draft OPW Environmental Procedures version 08/18 Rev A.


2 Project Description

2.1 Arterial Drainage Maintenance

Between 1945 and 1995, under the Arterial Drainage Act (1945), the OPW completed 34 Arterial Drainage Schemes on river catchments, along with five estuarine embankment schemes (over 11,500km of channel and 730km of embankments). The OPW is statutorily obligated to maintain arterial drainage channels under the 1945 Arterial Drainage Act, and since their completion, maintenance of these Arterial Drainage Schemes has been ongoing, with the majority of channels maintained every five years. However, larger channels tend to be only maintained every ten years, on average.

2.2 Drainage Maintenance Activities

Arterial Drainage Maintenance includes a range of operations such as silt and vegetation management, mowing and structure maintenance, as detailed in Table 2-1, and listed as channel, embankment or structure maintenance in Table 2-2 below. It is required to retain the arterial drainage scheme design capacity.

The following sections, taken from Ryan Hanley (2014a) and OPW (2011a), provide further details on the types and nature of arterial drainage maintenance operations undertaken by the OPW.

2.2.1 Channel Maintenance Activities

The majority of drainage maintenance activities are focused on channel maintenance. While the frequency of maintenance on an individual channel may vary, with some channels requiring maintenance annually and others only requiring maintenance every twenty years, the average channel requires maintenance every four to six years. In this regard, approximately 2,000km of channels are maintained annually and nearly all of the 11,500km of channels across Irelands Arterial Drainage Schemes will have been maintained at least once over a period of five years. Channel maintenance is organised on a regional basis, with OPW Arterial Drainage Maintenance Regional Offices in Limerick, Headford, Co. Galway and Trim, Co. Meath.

Scheme Design Standards

Arterial Drainage Schemes constructed under the Arterial Drainage Act, 1945 were designed to provide an outfall for drainage of agricultural lands, and generally provided protection for a 3-year flood event. Where the creation of an outfall dictated the design bed levels, greater protection than the 3-year flood event was achieved as a consequence. In the case of modern flood relief schemes, flood protection for a 100-year flood event would be the design objective.

The original Scheme designs, including the outfall datum for each of the Arterial Drainage Schemes, are available in the relevant OPW Arterial Drainage Maintenance Regional Office. This includes the mapped Scheme design, and the associated long sections and cross sections. These designs are used to inform channel maintenance.

Types of Channel Requiring Maintenance

In the years following the construction of a drainage scheme there is a tendency for the channel capacity to be progressively reduced due mainly to the transportation and deposition of bed materials, the accumulation of silt and the growth of in-channel vegetation. The resultant channel maintenance consists of repetitive works of a cyclical nature, to restore the Schemes design levels i.e. outfall datum in order to maintain the channel's designed capacity to convey water.

Channels are prioritised for maintenance based on the rate of deterioration and the risk arising. The selection takes account of requests from the general public and potential flooding risk to roads, properties, urban areas and sewage works (OPW 2011a).

Plane Bed to Low Gradient Channels

Some 60 – 70% of maintained channels are of gentle longitudinal gradient and subject to relatively rapid deposition of silt, especially those that are subject to prolific growth of in-channel vegetation. The majority of maintenance works are therefore located on smaller lower-lying channels, with 90% of works in channels with a base width of <3m (OPW 2011a). In such channels silt and in-channel vegetation may cause the low flow level to rise by 50-300mm above the Scheme design level. In such circumstances maintenance is focused on restoring both low-flow and flood-flow water levels to original Scheme design.

Medium to High Gradient Channels

A smaller proportion of channels are steep and fast flowing and are subject to flash floods, bank erosion and rapid movement of bed gravel. The steeper sections of channel normally require relatively little and infrequent maintenance works (OPW 2011a) as opposed to channels of low gradient which are subject to rapid accumulation of silt and proliferation of vegetation. These channels will have a greater requirement for bank protection works.

Periods and Cycles of Maintenance

The average channel requires silt and vegetation management every four to six years. However, channels with prolific weed growth may require maintenance annually, particularly where downstream bridges are at risk of being blocked due to a flow of decaying vegetation in autumn.


Conversely, some channels may only require in-stream maintenance every twenty years due to the self-cleaning characteristics e.g. high gradient channels.

Where the period between previous channel maintenance works has been exceptionally long, dense scrub and woody vegetation can establish along the channel and within the maintenance access corridor. In such circumstances, drainage maintenance works will include the removal of scrub/transitional woodland (code WS1 in the Fossitt Classification, 2000) that has developed along the banksides via bush cutting/branch trimming, tree cutting or mulching. This is undertaken between the 1st September and 28th February to avoid the residential bird nesting season (from the 1st March to 31st August as per the Wildlife Act (1976).

In contrast, in-stream works for silt and vegetation management are carried out outside of the salmonid spawning season (May to September) and the times that early life stages of salmonid fish will be present as per Section 173 of the Fisheries (Consolidation) Act (1959) on channels with salmonid spawning habitat. Any works required during this period are carried out in consultation with IFI. As a result, there may be a two-stage approach to the works, with silt and in-stream vegetation management carried out during the open season (i.e. summer months), while woody vegetation removal is carried out in the winter months.

Other restrictions on works may also apply in relation to the presence/absence of other protected species such as White-clawed Crayfish and Sea, River and Brook Lamprey which will influence the timing of works.

2.2.2 Embankment Maintenance Activities

A total of 5 No. Estuarine Embankment Schemes were constructed under the 1945 Act. In addition, a number of the Arterial Drainage Schemes have embanked sections. Embankments are present within the Lower Shannon Arterial Drainage Scheme.

Scheme Design Standards

As above for the Arterial Drainage Schemes, Estuarine Embankment Schemes constructed under the Arterial Drainage Act 1945 were designed to provide an outfall for drainage of agricultural lands, and generally provided protection for a 3-year flood event. Where the creation of an outfall dictated the design bed levels, greater protection than the 3-year flood event was achieved as a consequence. In the case of modern flood relief schemes, flood protection for a 100-year flood event would be the design objective.

The original Scheme designs are available in the relevant OPW Arterial Drainage Maintenance Regional Office. This includes the mapped Scheme design, and the associated long sections and cross sections.

Types of Embankments Requiring Maintenance

All embankments and associated sluice structures (see section 2.2.3) are inspected annually for signs of disrepair.

Regular inspections are carried out on sections of embankments, which are known from experience to be at risk, together with additional inspections after a storm surge at sea or a high tidal/flood event. Maintenance of embankments includes removal of vegetation to allow for inspection of the embankment, and in some cases the replacement of existing fencing with gates to allow for future access during maintenance.

2.2.3 Structural Maintenance Activities

Structural Design Standards

During the construction of the Arterial Drainage Schemes under the 1945 Act, some 18,500 No. accommodation bridges were identified and modified, or replaced as required. These bridges provide farmers owning land on both sides of a channels with farm vehicular and/or foot access from one side to the other. The type of bridge provided depended on the width, depth and required flow capacity of the channel, and ranged from concrete piped culverts to relatively large structures formed on concrete or masonry abutments spanned by structural steel beams, or lattice girders together with concrete or timber decking.


During the Estuarine Embankment Schemes under the 1945 Act, existing sluice structures were identified and modified, or replaced as required. Additional sluice structures were constructed as required bringing the total number to approximately 750. The function of these sluice structures is to allow water from the floodplain behind the embankments to discharge to the main river or estuary.

Types of Structures Requiring Maintenance

In general, as channel maintenance proceeds, the bridges are examined by the supervisory industrial staff and if required, repairs/replacements are scheduled. The type of bridge structures, which are most likely to have fallen into a critical state of disrepair, are those with timber decking supported on steel beams, and those in which abutment foundations are being undercut. There is a standard type of design for the replacement of these structures, which consists essentially of mass concrete abutments with reinforced cast in-situ decking. This type of structure is simple to construct and under normal circumstances, it will last for many years with little or no maintenance.

On many occasions, it is not necessary to totally replace a bridge, and repairs such as underpinning the foundation or replacement of wing-walls, parapets or sections of the deck may be all that is required to extend the useful life of the structure. Where bridge maintenance may be required, a Bridge Inspection Form will be filled out by the Foreman, prior to the works. This will determine the need for further assessment and potentially, any mitigation measures that may be required. See Appendix E- Foreman’s Bridge Inspection Report.

All embankments and associated structures are inspected annually for disrepair. Due to the time elapsed since scheme completion, some of these sluice structures have reached their design life and have started to fail. In this instance, full replacement is required. Typically, this involves the installation of pre-cast headwalls and back walls, and the replacement of existing corrugated galvanised steel pipes with PVC plastic pipes.

Sluice doors are the most frequent part of the sluice structure that are required to be repaired or replaced. Repairs to a sluice door consist of replacing the arms/hinges on the existing cast iron door. On occasion, the existing cast iron door would be replaced with a high-density polyethylene (HDPE) door. Blockages often occur at the doors of the sluices due to silt build up. These blockages are removed using along reach excavator working from the bank of the channel.

It is not known where bridges, sluice doors or structures may require maintenance on the Lower Shannon Scheme. Maintenance of bridges, structures and/or sluices will only occur within the scheme after following the relevant environmental procedures as detailed in the OPW Environmental Procedures document (OPW 2018) and using specific mitigation measures as defined in this document and Sections 6 and 7. Structures that are assessed in this NIS for potential impacts as a result of maintenance works are included in Appendix H.

This NIS does not include assessment for the removal, demolition, replacement or erection of bridges, sluices or structures.

2.2.4 Maintenance works considered outside of the Scheme Design Standards and outside of normal Arterial Drainage Maintenance Works

Occasionally, works are required that can be considered outside of the scope of the normal Arterial Drainage Maintenance Works to maintain a scheme. Works considered outside of the normal scope of statutory arterial drainage maintenance works have are not assessed for impacts in this report.

Works that could be considered outside of the normal scope of works include those involving extensive bank protection measures, removal of mature woodland, unplanned bridge maintenance works or any other unplanned works within the zone of influence of a Natura 2000 site.

2.2.5 Plant and Machinery

The types of machinery typically utilised during maintenance works would include 3600 hydraulic excavators (from 15-20 tonne excavators), mini-diggers, tractors and trailers, tipper lorries, hydraulic shears, hydraulic secateurs, chainsaws, mulchers and mowers; the machinery used is dependent on the maintenance activity being conducted.

The removal of dense in-stream silt and vegetation requires the use of a hydraulic excavator with a 1.5m wide (approximate) bucket (capacity approximate 500ltrs). For standard excavators, works


progress at a rate of 700m to 900m per week. In relation to long-reach excavators, works progress at a slower rate of between 200m and 350m per week. Rates may change due to channel width or ground conditions.

2.2.6 Maintenance Access Corridors (MAC) and Working Zone

Maintenance sites are generally accessed via the public road and through farmland. A maintenance access corridor is utilised along one side of a channel for maintenance purposes. These established routes are used to track the hydraulic excavators for maintenance and for the disposal of spoil (see section 2.2.8). The same route is generally followed every maintenance cycle. This approach avoids disturbance of habitats on the opposite bank during works.

Where grasslands are present within the maintenance access corridor, the impact is predominantly temporary as the grasslands are trampled by machinery and can recolonise following completion of the maintenance activities. Within woodland and scrub habitats a linear path more typical of disturbed vegetation i.e. scrub/transitional woodland (WS1) will be evident along the maintenance access corridor due to regular machine access. In this regard, the disturbance regime associated with the tracking of plant machinery along the maintenance access corridors on the channel bank arrests succession to mature woodland such that scrub/transitional woodland (WS1) dominates. Where mature trees are present these are generally avoided by plant machinery.

Structures are generally accessed through farmland from the public road above. Plant machinery will utilise the same maintenance access corridor used for channel maintenance to gain access to the structure. Where individual trees, woodland and scrub habitats are present at the location of the structure, these may be removed to facilitate bridge inspection and works. Where mature trees are present these are generally avoided by plant machinery.

The location of drainage maintenance works is generally accessed via public roads and through farmland, with the siting of mobile short-term staff welfare facilities, plant storage and car parking agreed with local landowners. There is no requirement for temporary site lighting.

There is a requirement for water supply and disposal of wastewater from the welfare facilities (see section 2.2.8 in relation to waste disposal).

2.2.7 Site Compounds (Welfare Facilities), Access Routes and Haul Roads

Haul roads are generally not required to facilitate drainage maintenance activities. Where access is required in soft ground conditions, plant equipment will be brought in on tracks or temporary matting will be laid to provide a corridor for machinery access. Where matting is utilised, it will be completely removed post completion of works to allow vegetation to recolonise. All plant and machinery is confined to one defined access route to minimise disturbance.

All plant and machinery are regularly maintained and serviced to minimise release of hydrocarbons. All hydraulic excavators and other plant machinery use long life engine oil and biodegradable hydraulic oil. Fuelling and lubrication are conducted a minimum of 50m away from all channels. Spill kits are present in all plant used in maintenance activities. Integrated submersible pumps are also deployed in the event of structural maintenance and the requirement for dewatering of excavations.

2.2.8 Waste Output/Disposal

The material removed from a channel during silt and vegetation management is normally spread thinly along the bank or on top of existing spoil heaps where present within the access corridor. All dead wood material is left on site to decompose or is removed off site and utilised as firewood under local landowner agreements. Where mulchers or mowers are deployed, the arisings are left on site to decompose or the mulched material is buried.

Construction and demolition waste from structures includes broken concrete and stone. Steel railings are returned to the depot for recycling. Used engine oil and hydraulic oil is disposed of by a licensed waste handler. Toilet facilities are maintained by a licensed waste handler. Any waste generated on site is returned to the depot for segregation and disposal by a licensed waste handler.


2.2.9 Working Hours

All maintenance activities are undertaken during daylight hours. Standard working hours are 8.00am to 4.30pm, with lunch and tea breaks, Monday to Friday. There is no requirement for temporary site lighting to facilitate works. Machines are powered down when not in use.

2.2.10 Environmental Training

Environmental training of all staff involved in drainage maintenance is an ongoing process. Technical and Operational Staff have completed formal training in Environmental Drainage Maintenance (EDM) in 2004. This training course was revised and expanded under the OPW’s Environmental River Enhancement Programme (EREP) and was delivered to all staff in 2010. The training programme delivered included presentations in river corridor ecology, the Environmental Drainage Maintenance Guidance Notes (Ten Steps to Environmentally Friendly Maintenance), maintenance strategies involving both ‘enhanced maintenance’ and ‘capital enhancement’, and OPW’s Environmental Management Protocols and Standard Operating Procedures (SOPs) (see section 0 for more details). Both sets of training were developed and delivered by Inland Fisheries Ireland (IFI).

The formal approach to EDM Training is complimented with on-site training. Regular site visits from IFI and OPW’s Environment Section provide further guidance and advice to operational staff. Auditing of operational staff on the implementation of the Environmental Drainage Maintenance Guidance Notes (Ten Steps to Environmentally Friendly Maintenance (OPW 2011b) is also carried out by both IFI and OPW’s Environment Section.

In addition, other environmental training takes place as deemed beneficial, e.g. in 2008, the majority of the technical and operational staff were trained in Otter Awareness. This course, provided by the Department of Zoology, Trinity College Dublin, included presentations on Otter ecology, and on-site identification of Otter signs and suitable habitat.

More recently, an environmental training course was designed and provided by JBA to all OPW staff in 2017 and 2018. It was given in three different stages. Management staff were given a more detailed 2-day course in Environmental and Ecological training. Ground staff were given 1.5 days of training in the environment and ecology. Modules were designed to assist staff in understanding the relevant legislation, recognising ecologically sensitive habitats and species, invasive non-native species identification and general environmental and ecological training relevant to their work. This included a half day practical session where ecologists demonstrated the identification of the elements taught in the classroom, in the field.

Training in the completion of an Environmental Risk Assessment and Bridge Inspections from an ecological perspective, was designed and provided by JBA Consulting to OPW Foremen and selected engineering staff in 2018.

2.2.11 Environmental Audits

A portion of operational crews have been audited annually by the OPW Environment Section, IFI and in 2018 by JBA Consulting for the implementation of the Environmental Drainage Maintenance Guidance Notes (Ten Steps to Environmentally Friendly Maintenance) and the OPW’s Environmental Management Protocol and EPs. Auditing is carried out by JBA Consulting and the OPW on a rotational basis to ensure all operational crews are audited at least once every three years. All audit results are discussed on-site and forwarded in full to the relevant engineer for that Scheme within two working weeks. In the event of an audit showing elements of unreasonable non-compliance with procedures, the relevant Engineer will be notified within one working day. Audit results are also forwarded to OPW Systems Manager for inclusion in monthly regional benchmarking reports.

2.2.12 Environmental Management Protocol and Standard Operating Procedures (SOPs)

The draft OPW’s Environmental Management Protocols (OPW 2018) set out how regional management staff manage a range of environmental aspects, including programming of works to accommodate certain environmental windows or restrictions on timing of works, and recording of data. A total of 31 No. EPs are applied during operational works. The 31 EPs replace the previous SOPs (OPW 2011b). The EPs will be rolled out across the OPW in 2018. These EPs set out actions designed to eliminate, or substantially reduce, likely impacts to identified species and their associated habitats. A brief summary of these follow.

The new Environmental Drainage Maintenance Manual is in Appendix, D and not yet publicly available at the time of drafting this NIS.

The description of activities, assessment and mitigation measures described in this report relate to the content of the draft OPW Environmental Procedures version 08/18 Rev A.

An Environmental Risk Assessment (ERA) process has been developed by the OPW which will be filled in by the program producer for >3m base width main channels where maintenance has not occurred for 15 years and embankment works where maintenance has not occurred for 15 years. The ERA form for this process is in Appendix F.

2.3 The Lower Shannon Arterial Drainage Scheme

The Lower Shannon Arterial Drainage Scheme is located in County Limerick. It includes 1,538.8km of watercourse and 230.7km of embankment (Figure 2-1).


Figure 2-1 Map of the Lower Shannon Scheme

2.4 Drainage Maintenance Works Proposed for the Lower Shannon Arterial Drainage Scheme

Within the Lower Shannon Arterial Drainage Scheme the exact location and type of required maintenance activity varies over time. For the purposes of this NIS not all activities will occur on all scheme channels, structures and embankments. However, due to the high level nature of this report, all normal drainage maintenance activities are assessed.


3 Screening Assessment An Appropriate Assessment screening assessment, addressing Stage 1 of the AA process, was originally completed for the Lower Shannon Arterial Drainage Scheme in 2014 (JBA 2014). This has been reviewed based on up to date information in this report and the Conservation Objectives for each site. Any amendments have been included in this report. The resulting AA Screening identified that likely significant effects on Natura 2000 sites may occur as a result of the proposed maintenance activities and therefore a Stage 2 Appropriate Assessment is necessary.

The Stage 1 Screening Assessment was conducted in line with guidance produced for the OPW in 2014 (Ryan Hanley 2014b, 2014a). This methodology is based on source > pathway > receptor chain principles and involves assessing likely significant effects on Natura 2000 sites within the zone of influence of the proposed drainage maintenance in relation to three pathways:

4. Surface water

5. Land & air

6. Groundwater

The screening assessment involved assessing the impacts of drainage maintenance operations within the arterial drainage scheme, and its zone of influence, in relation to each of the three pathways individually. Conclusions were then drawn to identify if maintenance works upon the channels within the scheme, could impact upon Natura 2000 sites. Sites that had the potential to be impacted by the maintenance works were determined to be within the ZOI and these sites require further assessment. The review of the previous screening included a review of the ZOI and an assessment of any new Natura 2000 sites, and/or any changes to current Natura 2000 sites within the ZOI. The screening assessment review also took into consideration the up to date information on the upcoming programme of works where relevant. The resulting screening assessment included the Natura 2000 sites in Table 3-1.

pathways

This assessment was determined based on presence of surface water connectivity between the Natura 2000 sites and the Lower Shannon Arterial Drainage Scheme and considering a variety of factors. Relevant factors considered in the assessment included the "At Risk" status (Under the Water Framework Directive (WFD)) of all surface waterbodies within the area of works, the potential for impact, the significance of potential impacts and the relevance of any threats and pressures within the Natura 2000 site. Significance was determined based on the nature of the surface water dependant (SWD) qualifying interests that may be present and the nature of the scheme based on the hydrological setting within the catchment. Pre-determined distances and typologies (Ryan Hanley 2014b) were used to define the zone of influence of the works and determine potential and significance of impacts.

Using the precautionary principle, during the screening assessment, SWD habitats and species that may be present were assessed as if present, based on information available in the Conservation Objectives, Natura 2000 Data Form and the Site Synopsis. These potentially present Qualifying Interests / Features of Interest were then assessed for the potential to be significantly impacted by the proposed works if present. The results of this assessment are in Table 3-3 and Table 3-4.

This assessment was determined based on the location of the relevant Natura 2000 sites within the relevant groundwater bodies and considering a variety of factors. Relevant factors considered in assessing the potential for the Natura 2000 site to be impacted through groundwater pathways also included the presence of Groundwater Dependant (GWD) QIs / FOIs, the risk status under the WFD of each site and the potential and significance of impact, should one occur. Each qualifying interest of the screened in Natura 2000 site, was then assessed individually for potential to be impacted and the overall assessment included a review of the potential for cumulative and/or in-combination impacts as a result of the identified pressures and threats identified in the Natura 2000 forms. The location of the drainage maintenance activity works relative to the Natura 2000 sites and features of interest were considered to determine relevance at this stage, along with GWD habitat typology. Pre-determined distances and typologies (Ryan Hanley 2014b) were used to define the zone of influence of the works and determine potential and significance of impacts.


Figure 3-3 Channels and embankments with potential impacts via groundwater pathways

Location of GWD QIs within the GWB, where available in the Conservation Objectives, Natura 2000 Data Form and the Site Synopsis, were used to determine if they were within the ZOI of the works and therefore, potentially at risk to be impacted by groundwater pathways. Where the location of GWD QIs were not available, the precautionary principle was used during the screening assessment. Species that may be present were assessed as if present throughout based on information available in the Conservation Objectives, Natura 2000 Data Form and the Site Synopsis. These potentially present QIs / FOIs were then assessed for potential to be significantly impacted by the proposed works if present. The results of this assessment are seen in Table 3-8.

3.4 Screening assessment conclusion

The screening assessment identified a number of Natura 2000 sites potentially within the ZOI of the Scheme. The screening assessed each of these sites for potential for significant impacts from the


proposed works of the Scheme, using the source-pathway-receptor model (Ryan Hanley 2014b). Askeaton Fen Complex SAC (002279), Ballyallia Lake SAC (000014), Ballycullinan Lake SAC (000016), Ballyogan Lough SAC (000019), Curraghchase Woods SAC (000174), Danes Hole, Poulnalecka SAC (000030), Dromore Woods and Loughs SAC (000032), East Burren Complex SAC (001926), Glen Bog SAC (001430), Lower River Shannon SAC (002165), Moyree River System SAC (000057), Pouladatig Cave SAC (000037), Poulnagordon Cave (Quin) SAC (000064), Tory Hill SAC (000439), River Shannon and River Fergus Estuaries SPA (004077), Ballyallia Lough SPA (004041) and Corofin Wetlands SPA (004220) have been identified as potentially being significantly affected by drainage maintenance operations undertaken within the Lower Shannon Arterial Drainage Scheme. These conclusions are based on the assumption that all drainage maintenance activities specified in Section 2.2, are to be undertaken on all watercourses, embankments and structures during the life of the plan (2019-2023).

Channels, Embankments, Bridges and Sluices of this Scheme that are included in this screening and their pathways of impact relevant to each Natura 2000 site are in Appendix H.

From this screening exercise it has been determined that significant likely effects may arise on the above Natura 2000 sites as a result of OPW drainage maintenance activities, through surface water, groundwater and land and air pathways as shown in Table 3-9.

4 Existing Environment This section summarises the findings of the ecological walkover surveys of the river channel and the results of the desktop survey relative to the proposed works for the Lower Shannon Arterial Drainage Maintenance Scheme (2019-2023). The habitat and species results in Sections 4.3, 4.4, 4.5 and 4.6 are a result of the data gathered from both the desktop review and the walkover surveys. Desktop review data was collated from NBDC (2018) database and included protected habitats and species recorded as being present within the surrounding 10 km areas of the Scheme, within the past 10 years. Data was gathered from 34 10x10km2 to encompass the entire works of the scheme and collated in Excel (Figure 4-1). Collated datasets are in Appendix B and Appendix C.

A complete GIS database containing all species and habitats identified during the walkover surveys, including those relevant to the NIS and those not relevant but ecologically significant or protected under other legislation, has been provided separately to the OPW.

4.1 General

The works that will occur on the Lower River Shannon Scheme cover an extensive area including the Counties of Clare, Limerick, Tipperary and Cork. Large towns or cities that are located within 15 km of the works within County Limerick include Abbeyfeale, Annacotty, Castleconnell, Croom, Kilmallock, Limerick, Newcastlewest and Rathkeale. Large towns or cities that are located within 15 km of the works in County Clare include Ardnacrusha, Ennis, Killaloe, Newmarket-on-Fergus, Shannon and Sixmilebridge.The works extend into a small area of Counties Cork and Tipperary only. The largest town in County Cork near the area of works is Milford. The largest Town near the area of works in County Tipperary is Newport.

A variety of bedrock types underlie this area including carboniferous limestone to Foynes, but west of Foynes Namurian shales and flagstones predominate (except at Kerry Head, which is formed from Old Red Sandstone). The Mulkear flows through Lower Palaeozoic rocks in the upper reaches before passing through Namurian rocks, followed by Lower Carboniferous shales and Carboniferous limestone. The Mulkear River itself, immediately north of Pallas Green, passes through an area of Rhyolites, Tuffs and Agglomerates (NPWS 2013c). To the north and south of


the Shannon Estuary, the landscape is underlain with carboniferous limestone resulting in a variety of ecological features of interest including Turloughs [3180], Caves [8310] and associated habitats and species (NPWS 2013e, 2014, 2016).

Shannon International River Basin (IRBD) is the largest river Basin in Ireland at more than 18,000km2. The Shannon IRBD is a largely rural district with many protected sites that depend on water (54% of rivers have protected areas associated with them) (EPA 2010).

4.2 Ecology - overview

To further inform the Appropriate Assessment process, multiple ecological walkover surveys were conducted of the channels within 100m of Natura 2000 sites in the Lower River Shannon Scheme, by multiple surveyors throughout August and September 2018. These surveys were completed by JBA lead ecologists Tanya Slattery, Patricia Byrne, Steven Heathcote and Jennifer Pullen and assistant ecologists Catalina Herrera, Colm O'Leary, Malin Lundberg, William Mulville, Joe Freijser, Sarah King, Lea Nightingale and Mairi Gillis. Independent ecologists Michelle O'Neill and Domhnall Finch conducted ecological surveys on the Maigue Scheme and the North Shannon (Fergus).

Habitats recorded adjacent to the Scheme can be found in Table 4-1 and are described in Section 4.3

Forty-one Fossitt habitats were identified during the ecological walkover surveys in the Scheme.

Of the 41 habitats, five have been described as potential Annex I habitats:

• Atlantic salt meadows (Glauco-Puccinellietalia maritimae) (1330)

• Estuaries (1130)

• Alluvial forests with Alnus glutinosa and Fraxinus excelsior (Alno-padion, Alnion incanae, Salicion albae) (91E0)

• Watercourses of plain to montane levels with the Ranunculion fluitantis and Callitricho-Batrachion vegetation (3260)

• Hydrophilous tall herb fringe communities of plains and of the montane to alpine levels (6430)

A number of protected species were recorded during the ecological survey including Otter Lutra lutra, White-clawed Crayfish Austropotamobius pallipes, Badger Meles meles, Kingfisher Alcedo atthis, and Curlew Numenius arquata.

Non-native invasive species most commonly recorded were Himalayan Balsam Impatiens glandulifera, Giant Hogweed Hercleaum mantegazzianum, and Japanese Knotweed Fallopia japonica.

4.3 Ecology Walkover Survey Results

Habitats identified according to Fossitt (2000), during the ecological walkover survey, including details of plant species found are in the following sections. Where no species of interest were noted during the survey, the description of species present is as identified in Fossitt (Fossitt 2000).

4.3.1 Stone walls and other stonework

Found in a few locations in the Scheme, recorded species include Ivy Hedera helix and Harts-tongue fern Asplenium scolopendrium. Stone walls may support a diverse flora with abundant lichens, mosses and ferns Asplenium trichomanes, A. ruta-muraria and A. ceterach. Other common components include grasses (Aira and Catapodium spp.), stonecrops Sedum spp., Herb-robert Geranium robertianum and Navelwort Umbilicus rupestris. Non-native species such as Red Valerian Centranthus ruber, Wallflower Erysimum cheiri and Ivy-leaved Toadflax Cymbalaria muralis are often prominent.

4.3.2 Earth Banks

Found occasionally across the survey site, this habitat is often used to describe vegetated spoil heaps next to the channel and is often included in a mosaic with drainage ditches and improved agricultural grassland. They are constructed from local materials such as peat, earth, gravel or stone, are completely vegetated when intact and feature elements of a range of habitats. They are often lightly grazed and unfertilised, supporting abundant grasses and a wide range of broadleaved


herbs such as Foxglove Digitalis purpurea, violets Viola spp., Yarrow Achillea millefolium, Common Knapweed Centaurea nigra, Wild Strawberry Fragaria vesca and Primrose Primula vulgaris.

4.3.3 Building and artificial surfaces

This habitat is found throughout the Scheme, it generally consists of farm roads, gravel tracks, farmyards as well as structures including houses, farm buildings and bridges.

4.3.4 Shingle and gravel banks

Found in small patches on the Rine River and on the estuary on the Ringmoylan Mellon sub-scheme (Figure 4-2). This habitat develops in coastal areas where shingle and gravel have accumulated to form elevated ridges or banks above the high tide mark. Fossitt describes the common colonisers of stony banks as Lichens and mosses, Sea Sandwort Honkenya peploides, Annual Sea-blite Suaeda maritima, Sea Beet Beta vulgaris, Rock Samphire Crithmum maritimum, Sea Mayweed Tripleurospermum maritimum, Herb-robert and Cleavers Galium aparine.

Figure 4-2 Shingle and gravel bank on the Shannon estuary

4.3.5 Sea wall, piers and jetties

This habitat is found along the estuary of the River Shannon and Fergus, and on the Ringmoylan-Foynes and Ringmoylan Mellon sub-scheme. It consists of all coastal constructions that are partially or totally inundated by sea water at high tide, or subject to wetting by sea spray or wave splash.


4.3.6 Lower salt marsh

Found in only a few locations along the estuary, with one site on the Coonagh sub-scheme recorded as potential Annex I habitat Atlantic salt meadows (Glauco-Puccinellietalia maritimae) (1330). It is subject to more prolonged submersion by sea water and is more strongly saline than upper salt marsh. Common Saltmarsh-grass Puccinellia maritima usually dominates the seaward edge of the salt marsh and often forms a short turf with glassworts Salicornia spp. Along the Shannon, Lower saltmarsh often includes NNIS Common Cord-grass Spartina anglica (Figure 4-3).

Figure 4-3 Lower salt marsh dominated by Common Cord Grass

4.3.7 Upper salt marsh

This habitat occurs in long linear stretches along the estuaries of the Scheme, often found next to in or in mosaics with Reed and Sedge Swamp and/or Wet Grassland habitats, and occasionally recorded as being dominated by NNIS Common Cord-grass.

It is subject to less frequent and less prolonged inundation by the sea than lower salt marsh. It is typically dominated by rushes (particularly Juncus maritimus and J. gerardii) and grasses Red Fescue Festuca rubra and Creeping Bent Agrostis stolonifera.

4.3.8 Lagoons and saline lakes

The main location of this habitat is beside the tunnel on the Southern Limerick ring road (N18). A small area of this habitat is also found on the Ringmoylan-Foynes (Bushy Island) sub-scheme. It is described as an enclosed body of standing brackish water that are wholly or partially separated from the sea where tidal influence is much reduced. Lagoons are often important habitats for wading and wintering birds.

4.3.9 Tidal rivers

The Shannon Estuary and the lower reached of its tributaries are tidal in nature. Vegetation in this habitat is tolerant to variations in salinity and turbidity. Species present include Sea Lettuce Ulva intestinalis, Fool’s Water-cress Apium nodiflorum, starwort Callitriche stagnalis, and Hemlock Water-dropwort Oenanthe crocata.


4.3.10 Recolonising bare ground

Occurring in only a few locations across the scheme, this habitat is recorded to have species including Bramble Rubus fruticosus agg., willows Salix spp., thistles Cirsium spp., Broom Cytisus scoparius, and some grass sp. This habitat includes any areas where bare or disturbed ground, derelict sites or artificial surfaces of tarmac, concrete or hard core have been invaded by herbaceous plants includuing Colt’s Foot Tussilago farfara, Nettle Urtica dioica, Dandelion Taraxacum spp., willow-herbs Epilobium spp. and ragworts Senecio spp.

4.3.11 Refuse and other waste

An uncommon habitat in this scheme, it has been recorded to contain species such as Flag Iris Iris pseudacorus, Enchanters Nightshade Circaea lutetiana, Fool’s Water-cress Apium nodiflorum, water mint, Brooklime Veronica beccabunga, Nettle Urtica dioica, Angelica, and Meadowsweet Filipendula ulmaria. It is identified by stands of herbaceous vegetation that occur in wet areas where the water table is above the ground surface for most of the year and is dominated by robust herbs. Tall-herb swamps have the potential to be the Annex 1 Habitat Hydrophilous tall herb fringe communities of plains and of the montane to alpine levels (6430), however this was not identified


during the walkover surveys. It has however, been identified as being present in and around Lower River Shannon SAC and may be present within the area of works in tall-herb swamp habitats.

4.3.15 Eroding/upland rivers

A common habitat in this scheme found across many of the sub-schemes. More likely to be found inland, it is often recorded in a mosaic with habitats found on the banks of the river including Riparian woodland, Treelines, earth banks, improved agricultural grassland, wet grassland and dry meadows and grassy verges. It is described often with stones, cobbles and boulders in the river and with eroding or overgrown banks and berms adjacent (Figure 4-5).

This type of natural watercourse is described by Fossitt (2000) as actively eroding and unstable. Submerged rocks and boulders may be colonised by aquatic mosses such as Fontinalis spp. and Racomitrium aciculare. Exposed rocks and wet shaded banks may also support extensive cover of lichens and liverworts. Higher plants are generally rare or absent except in places where fine sediments are trapped.

Figure 4-5 Depositing lowland river habitats and eroding upland rivers

4.3.16 Depositing/lowland rivers

This is a common habitat that is found across the scheme and may form a mosaic habitat with eroding upland rivers. It is described often in mosaic with Riparian woodland, improved agricultural grassland, wet grassland and dry meadows and grassy verges. Duckweed Lemna gibba, Fool's Watercress, Water mint Mentha aquatica, Common Reed, water-lily spp., Hemlock Water-dropwort are often recorded, as well as algae and mosses growing in or near the water on boulders. Sometimes the river banks have been poached by cattle and algal blooms occur showing nutrient enrichment. In cases of mosaics with Riparian woodlands, willows, Sycamore and alder are common species (Figure 4-5). Water-crowfoots Ranunculus sp. were recorded in parts of the river, which could correspond to Annex I habitat 'Watercourses of plain to montane levels with the Ranunculion fluitantis and Callitricho-Batrachion vegetation (3260)'.


Figure 4-6 Water-crowfoot Ranunculus sp. in depositing rivers

4.3.17 Drainage ditches

This habitat is found extensively throughout the Scheme, often in mosaics with Improved agricultural grassland, Treelines, and Hedgerows. Drainage ditches are linear channels that are entirely artificial in origin, or watercourses that have been excavated or modified to enhance drainage and control the flow of water. Plant species can include Reed-canary grass, Common Reed, Duckweed, Meadowsweet, Water-mint, Nettle, Thistles, Angelica, Willowherb Epilobium sp, Purple Loosestrife Lythrum salicaria, Watercress Nasturtium officinale, horsetails Equisetum sp. within or directly adjacent to the ditch. Bramble, Hawthorn Crataegus monogyna and willow sp. often form hedgerows or treelines around them.

4.3.18 Improved agricultural grassland

This is a regularly occurring habitat found in the Scheme. It is described as intensively managed or highly modified agricultural grassland that has been reseeded and/or regularly fertilised and is often heavily grazed and/or used for silage making. It is typically species-poor and due to the domination of Rye-grasses Lolium spp., and often in association with White Clover Trifolium repens. It is often found in mosaics with treeline and drainage ditches, as well as other grassland types such as wet grassland, dry calcareous and neutral grassland, and dry meadows and grassy verges. Docks and Thistles were regularly recorded, as well as clover, daisy, and dandelion (Figure 4-7).


Figure 4-7 Improved Agricultural grassland

4.3.19 Amenity grassland (improved)

Found in a few sites, usually in populated areas in the Scheme such as Limerick City, Sixmilebridge, Croom, Curraghchase, this type of grassland is improved, or species-poor, and is managed for purposes other than for farmland. They are regularly re-seeded, mown and fertilisers and herbicides are often applied. The vegetation is made up of various grasses, and broadleaved herbs such as Daisy Bellis perennis, Dandelion Taraxacum spp., clovers and plantains Plantago spp. are common.

4.3.20 Marsh

A less common habitat in this scheme, marsh occurs on level ground near river banks and lakeshores where the water table is close to ground level for most of the year. Species recorded include Meadowsweet Filipendula ulmaria, Fleabane Pulicaria dysenterica, Common knapweed, meadow vetchling Lathyrus pratensis, rushes Juncus sp., Angelica, Marsh Cinquefoil Potentilla palustris, Timothy Phleum pratense and Reed Canary-grass. It often supports a high proportion of wetland species in addition to the typical dominants of rushes Juncus spp. and sedges Carex spp. Marsh has the potential to be the Annex 1 Habitat Hydrophilous tall herb fringe communities of plains and of the montane to alpine levels (6430), however this was not identified during the walkover surveys as being present within the survey areas. It has however, been identified as being present in and around Lower River Shannon SAC (Martin et al. 2013) and may be present within the area of works in marsh habitats including those at Tory Hill SAC.

4.3.21 Dry calcareous and neutral grassland

This habitat is found occasionally along the embankments of the Scheme. Species present included Yarrow Achellia millefolium, Bird's-Foot trefoil Lotus corniculatus, Wild Angelica Angelica sylvestris, Oxeye Daisy Leucanthemum vulgare, Common Knapweed Centaurea nigra, Quaking Grass Brizia media, bents Agrostis spp., Timothy and fescues Festuca spp.. This habitat can correspond to a number of Annex I habitats, however in all instances, the variety of species present indicated that this could be considered low quality habitat that was likely to have succeeded from improved agricultural grassland.


4.3.22 Dry meadows and grassy verges

This habitat is found numerous times across the Scheme, often in narrow stretches on the embankments as grassy verges and occasionally as part of a mosaic habitat with Scrub and Earth Banks. Grassy verges are occasionally mown and rarely treated with herbicides, and there is little or no grazing or fertiliser application. This habitat typically had a high proportion of tall grasses such as False Oat-grass Arrhenatherum elatius and Cock’s-foot Dactylis glomerata with a variety of broad-leaved herbs including Nettle, Creeping Thistle Cirsium arvense, Bindweed Calystegia sepium and Ragwort Senecio jacobea.

4.3.23 Wet grassland

This habitat, often in mosaic with other grassland or wet habitat types, is found occasionally across the Scheme. It is occasionally presented as improved agricultural grassland that is succeeding to wet grassland, or marsh that may be drying out. Broadleaved species recorded during the ecological surveys include Yellow flag, Meadowsweet, Silverweed Potentilla anserina, Meadowsweet, Purple loosestrife and Devils-bit Scabious Succisa pratensis. Wet grassland has the potential to be the Annex I habitat 'Molinia meadows on calcareous, peaty or clayey-silt-laden soils (Molinion careuleae) (6410), however, incufficent positive indicator species were identified as being present during all surveys of this habitat type and therefore, it was determined that this Annex I habitat is not present within the survey area.

4.3.24 Sand shores

This habitat includes exposed to sheltered shores of coarse, medium or fine-grained sand, usually with a very small proportion of gravel and mud (<10%) with includes vascular plants such as oraches Atriplex spp., Sea Rocket Cakile maritima, Saltwort Salsola kali and Annual Sea-blite Suaeda maritima. There may also be some sparse cover of Sand Couch Elymus juncea, Lyme-grass Leymus arenarius, Sea Sandwort Honkenya peploides and Sea-holly Eryngium maritimum

4.3.25 Muddy sand shores

This category includes shores where most of the sand is medium or fine (<1mm in diameter) and where muds (the silt/clay fraction) make up 10-30% of the sediment

4.3.26 Mud shores

This habitat is recorded in a few locations, with a few locations identified as potential Annex I habitat ‘mudflats and sandflats not covered by sea water at low tide (1140)’, on the Ringmoylan-Foynes Foynes and Ballysteen sub-schemes. Mud shores are formed primarily of very fine sediment and usually occur along the most sheltered sections of coastline. The silt/clay fraction of the sediment (particle sizes of <0.063 mm in diameter) should be at least 30% (Figure 4-8).


Figure 4-8 Mud shore and Estuary in the Shannon Estuary near Foynes

4.3.27 Mixed sediment shores

This habitat is composed of poorly sorted mixtures of sediments of different grades, including pebbles, gravel, sand and mud and often support some cover of fucoids (particularly Fucus spp.) or ephemeral green seaweeds Cladophora spp.

4.3.28 Estuaries

There are many Estuaries identified in the scheme, including the Owengarney River, River Maigue, Barnakyle River, and the Shannon. Some of these locations have been identified as the Annex I habitat ‘Estuaries (1130)’. Estuaries are semi-enclosed bodies of water which have a free connection with the open sea. Sea water is measurably diluted by inputs of freshwater and this, combined with tidal movement, means that salinity is permanently variable. The mixing of two very different water masses gives rise to complex sedimentological and biological processes and patterns (Figure 4-8).

4.3.29 (Mixed) broadleaved woodland

Found in scattered locations across the Scheme, species found during the survey include canopy and understorey species such as Hazel Corylus avellana, Alder Alnus glutinosa, hawthorn, Blackthorn Prunus spinosa, Ash Fraxinus excelsior, Sycamore Acer pseudoplatanus, Norway Spruce Picea abies, Pedunculate Oak Quercus robur, Elder Sambucus nigra, Beech Fagus sylvatica.

4.3.30 Mixed broadleaved/conifer woodland

This is a small habitat type in the scheme, found in mosaics and composed of Beech or Horse Chestnut Aesculus hippocastanum. This general category includes woodland areas with mixed stands of broadleaved trees and conifers.

4.3.31 Conifer plantation

A few conifer plantations composed of Norway Spruce are found in the extent of the Scheme. This category is used for areas that support dense stands of planted conifers where the broadleaved component is less than 25% and the overriding interest is commercial timber production. Conifer plantations are often surrounded by a narrow boundary of mixed broadleaved woodland.


4.3.32 Hedgerows

This is a common habitat across the Scheme dominated by Hawthorn Crataegus monogyna. but often includeding Blackthorn Prunus spinosa, Gorse Ulex europaeus, Holly Ilex aquifolium, Dog-rose Rosa canina or Bramble Rubus fruticosus agg., Ash, Hazel Corylus avellana, Beech Fagus sylvatica, Elder Sambucus nigra, elms Ulmus spp. and willows Salix spp.

4.3.33 Treeline

Often occurring along river banks and as a boundary to fields or drainage ditches, this common habitat is also found along the embankments, generally parallel to the river in many locations It often includes a variety of species including Ash, Sycamore, Alder Alnus glutinosa, and willows. Hedgerows and treelines often occur together around field boundaries.

4.3.34 Riparian woodland

Found in small patches along the Shannon estuary and tributaries. Some locations have potential to be the priority habitat, ‘*alluvial forests with Alnus glutinosa and Fraxinus excelsior (Alno-padion, Alnion incanae, Salicion albae) (91E0). The locations of these have been provided in the GIS database with all other ecological survey records to the OPW. During the ecological surveys, species recorded include Willows Salix cinerea, S. Alba, S. Fragalis, Common Reed, Nettles, Hemlock Water Dropwort and Alder (Figure 4-9).

Figure 4-9 Riparian Woodland

4.3.35 Wet willow-alder-ash woodland

This habitat is present in a few locations of the Scheme, including A section of this habitat on the north side of the Shannon along Channel D1 and Embankment E1 of the Coonagh Sub-Scheme edge, A section in the Ringmoylan-Foynes Sub-Scheme along the south of the Shannon Estuary, and it is at multiple locations around Limerick City near Channel C1 of the Ballynaclogh Sub-scheme. A variety of willows including Salix cinerea and Salix alba are recorded. Ash and Alder are also present and around the Ballyclogh Sub-Scheme, dumping occurs frequently. Ground layer species recorded include Common Reed, Common Fleabane, and sedges, Purple Loosestrife, Yellow Iris, Greater Willowherb, Angelica, Reed Canary Grass, Silverweed and Water Mint. This habitat has the potential to be the priority habitat, ‘*alluvial forests with Alnus glutinosa and Fraxinus excelsior (Alno-padion, Alnion incanae, Salicion albae) (91E0).

https://en.wikipedia.org/wiki/Corylus_avellana


4.3.36 Scrub

Scrub is commonly recorded across the Scheme, often in mosaic with improved agricultural grassland, Treelines, and Hedgerows. It is recorded with species such as Bramble, Gorse, Willow, Nettle, thistles, Purple Loosestrife, Reed Canary Grass, Nettle, Bramble, Iris, Gorse, Ivy Hedera helix, Bracken Pteridium Aquilinum and Invasive Himalayan Balsam and Japanese Knotweed. There are many occurrences of this habitat in mosaic with (Mixed) broadleaved woodland, Improved agricultural grassland, and Dry meadows and grassy verges.

4.3.37 Immature woodland

Immature woodland is present in a few small areas on the north side of the Rine. This habitat is described as areas that are dominated by young or sapling trees that have not yet reached the threshold heights.

4.3.38 Short rotation coppice

This habitat is found in small amounts on along the River Rine. It is described as areas where frequent coppicing or harvesting of trees and shrubs prevents the development of mature woodland including species such willows and poplars, often grown for biomass or basket-making.

4.4 Flora

There were no plant species listed under the Flora (Protection) Order 2015 found during the ecological walkover surveys.

Protected flora identified on the NBDC (2018) website present within approximately 10 km of the survey area includes Large White-moss Leucobryum glaucum, Meadow Barley Hordeum secalinum, Triangular Club-rush Schoenoplectus triqueter and Opposite-leaved Pondweed Groenlandia densa . A full list is in Appendix B. This table includes their level of protection, if they are red or amber listed on the International Union for the Conservation of Nature and Natural Resources (IUCN) Red List and the date of the last record of this species at this location.

4.5 Fauna

Evidence of protected and listed Fauna found along the Scheme during ecological surveys is described in the following sections. Records of protected fauna includes invertebrates, birds, mammals and amphibians collated from the NBDC (2018) database, present within the surrounding 10 km within the past 10 years. This table includes their level of protection, if they are red or amber listed on the International Union for the Conservation of Nature and Natural Resources (IUCN) Red List and the date of the last record of this species at this location.

Due to the nature of the survey Sea Lamprey Petromyzon marinus, Brook Lamprey Lampetra planeri, River Lamprey Lampetra fluviatilis and Salmon Salmo salar, which are all the QIs for the Lower River Shannon SAC were not recorded during the surveys and are not recorded in the NBDC database as being present in the Scheme area. However, as per the Lower River Shannon SAC site synopsis, the three lamprey species and salmon have all been observed spawning in the lower Shannon and its tributaries (NPWS 2013c) so they are assumed to be present throughout.

4.5.1 Invertebrates

Marsh Fritillary Euphydryas aurinia, an Annex II listed butterfly species under the EU Habitats Directive, has been recorded within 10km of the Scheme in the past 10 years.

Evidence of White-clawed Crayfish Austropotamobius pallipes was recorded during the ecological walkover surveys, on the channels near Tory Hill on the Maigue Outfall Scheme and on the Mulkear sub-scheme in the scat of Otter and crayfish burrows (Figure 4-10). They may be present at other locations throughout the Scheme, particularly in the freshwater channels, but due to the nature of the surveys conducted they were not always evident.


Figure 4-10 Crayfish remains on a rock in the Mulkear River

4.5.2 Birds

Protected and listed bird species observed during the ecological survey include Curlew Numenius arquata, Kingfisher Alcedo atthis, Buzzard Buteo buteo, Grey Wagtail Motacilla cinerea, Heron Ardea cinerea, Mallard Anas platyrhynchos and Dipper Cinclus cinclus. No nests were observed for any of these species.

There are three SPAs in the Scheme catchment including the River Shannon and Fergus SPA, Ballyallia Lough SPA, and Corofin SPA. The QI for these SPAs can be found in Sections 5. All QI bird species and other protected bird species that have been recorded in the Scheme catchment within 10km in the past 10 years can be found in Appendix B.

4.5.3 Mammals

Evidence of Otter Lutra lutra had been recorded across the survey area in the form of spraints, potential holts and otter slides and paths to the channel, and couches along the river bank. Otter is a Qualifying Interest for the Lower Shannon SAC, East Burren Complex SAC, and the Moyree River SAC, and has been recorded in the Scheme within the past 10 years (NBDC 2018).

Potential bat roosts and foraging areas were recorded during the ecological survey across the scheme. Lesser Horseshoe Bat Rhinolophus hipposideros is a qualifying interest for six SACs in the Scheme including Curraghchase Woods SAC, Danes Hole, Poulnalecka SAC, Dromore Woods and Loughs SAC, East Burren Complex SAC, Moyree River System SAC, Pouldatig Cave SAC, and Poulnagordon Cave SAC. Lesser Horseshoe Bats have been recorded at many locations in the past 10 years within 10km of the Scheme (NBDC 2018). Due to the nature of the surveys conducted and the limitations and constraints of surveying and data collection as identified in Section 1.4.5, it is likely that further, unidentified roosts may be present within the ZOI of the scheme.

Mammals recorded that are not QIs but are protected and/or of ecological interest include Stoat Mustela erminea subsp. hibernica, Pine Marten Martes martes, Hare Lepus timidus, and Badger Meles meles. All of these species have been recorded in the Scheme area within the past 10 years (NBDC 2018). Badger evidence was recorded a number of times including a sett on the Mulkear River, scat, snuffle holes and foraging scrapes throughout the Scheme Area (Figure 4-11). Other mammals found in the catchment of the Scheme can be found in Appendix B. The locations of all protected habitat and species identified, including those that are not QIs of the screened in Natura 2000 sites, are provided to the OPW in the form of a GIS database.


Figure 4-11 Badger sett on the Mulkear River

4.5.4 Amphibians and Reptiles

The Common Frog Rana temporaria has been recorded several times during the ecological surveys. Common Lizard Zootoca vivipara, Common Frog and Smooth Newt Lissotriton vulgaris were regularly recorded in the surrounding 10km of the Scheme in the past 10 years (NBDC 2018).

4.6 Non-Native Invasive Species

Non-native Invasive species recorded during the ecological walkover surveys include Japanese Knotweed Fallopia japonica, Giant knotweed Fallopia sachalinensis, Himalayan balsam Impatiens glandulifera, Giant Hogweed Hercleaum mantegazzianum, Floating Pennywort Hydrocotyle ranunculoides, Canadian Waterweed, Rhododendron and Common Cord-grass. These species are listed on EC (Birds and Natural Habitats) Regulations 2011 S.I. No. 477/2011. Species listed under S.I. No. 477/2011 are subject to restrictions under Regulations 49 and 50 of the 2011 Regulations (S.I. No. 477/2011 - European Communities (Birds and Natural Habitats) Regulations 2011. 2011). This includes a prohibition on the introduction and dispersal of these species.

Other NNIS species, listed on the NBDC database as Invasive Species, that were observed in the Scheme works areas during the surveys include Winter Heliotrope Petasites fragrans, Cherry Laurel Prunus laurocerasus, Least Duckweed Lemna minuta, Buddleia, Montbretia Crocosmia x crocosmiiflora, Snowberry Symphoricarpos albus and Sycamore.

Crayfish Plague Aphanomyces astaci has been recorded as present on the River Deel on Channel C1. Crayfish plague is spread easily by contaminated equipment and has also been recorded on the Lorrha River, upstream of the Lower River Shannon SAC and Lough Derg.

The extent and spread of Giant Hogweed was particularly notable along the Mulkear River.

The only animal invasive species recorded during the survey was Mink Neovison vison. Mink tracks were recorded near Bunratty. This species has the potential to be present throughout the entire Scheme.


Appendix C includes a full list of all of non-native invasive species from the National Biodiversity Data Centre database within 10 km surrounding the Schemes, as shown in Figure 4-1, within the last 10 years.

common NNIS found along the Scheme during the ecological walkover surveys


5 Natura 2000 sites within the Zone of Influence of the Scheme This chapter provides baseline information on the Natura 2000 sites within the Zone of Influence of the drainage maintenance activities (i.e. that screened into the assessment as detailed in Section 3). Sites include:







• Dromore Woods and Loughs SAC (000032)










• Corofin Wetlands SPA 004220

Figure 5-1 Overview of Lower Shannon Scheme and Natura 2000 sites


A short description for each site is provided, along with details of the qualifying interest/special conservation interests within the zone of influence.

Conservation objectives, the attributes used to define favourable conservation status are detailed in Appendix A.

The location of the Natura 2000 sites are shown in Figure 5-1, Figure 5-2, Figure 5-3, Figure 5-4, Figure 5-5 and Figure 5-6, where it can be seen where the proposed works will occur relative to these Natura 2000 sites. The main potential impacts posed by the proposed project relate to impacts during scheme works via surface water, land and air and groundwater pathways to the SACs.

5.1 Askeaton Fen Complex SAC (002279)

Askeaton Fen Complex consists of a number of small fen areas underlain by carboniferous limestone. It is located to the east and south-east of Askeaton in Co. Limerick, overlapping the Scheme in parts. Channel C1/17/4 and C1/17/4/7 are directly adjacent to the Maigue Outfall Sub-scheme. The fen complex is represented by a diversity of fen types in a gradient of habitats from open water to drier seepage areas. Cladium Fen is the most common fen type within the SAC and is associated with wet conditions, generally not more than 25cm deep. Great Fen-sedge Cladium mariscus occurs in mono-dominant stands, co-dominated by Common Reed Phragmites australis in drier areas. Alkaline Fen, characterised by the presence of Black Bog-rush, brown mosses and small sedges, is present in permanently waterlogged soils that are not normally flooded. Examples of this fen are found around the edge of most of the sites. Snipe and birds of prey use the site and a small area of limestone rich species grassland is found to the north of Balinvirick fen.

This site is of conservation value because it supports two fen types, each of which exhibit many sub-types. Cladium fen is listed as an Annex I priority habitat under the E.U. Habitats Directive. These wetland habitats of fen, reedbeds, open water, marsh and wet grassland are also valuable in that they supply a refuge for fauna in an otherwise intensively managed countryside.

5.1.1 Qualifying Interests

The site is a Special Area of Conservation (SAC) selected for the following habitats and/or species listed on Annex I / II of the E.U. Habitats Directive (* = priority; numbers in brackets are Natura 2000 codes):

• Calcareous fens with Cladium mariscus and species of the Caricion davallianae [7210]

• Alkaline fens [7230]

All qualifying features could potentially be present in the zone of influence of the proposed works and therefore all are considered further for significance of impact.

5.1.2 Conservation Objectives

A full list of the conservation objectives of the relevant Feature of Interest of the SAC is required in order to determine potentially adverse impacts to them. This information is provided in Appendix A.1

5.1.3 Site Vulnerabilities

5.2 Ballyallia Lake SAC (000014)

Ballyallia Lake is a relatively small, shallow lake situated on the River Fergus approximately 4km north of the town of Ennis, 5km (direct) from embankments E16 and channels D16 and D17 of the Shannon Embankments North Scheme. Little is known about the characteristics or ecology of Natural Eutrophic lakes [3150] for which this site is designated, however, it is associated with base rich lakes, with circumneutral or higher pH, in low lying, large, naturally more productive catchments and is characterised by high abundance and diversity of pondweeds (Potamogeton spp.) and mesotrophic values for total phosphorus and chlorophyll. It is considered to occur in Ballyallia Lough in this SAC and possibly also in Lough Girroga. Agricultural intensification of the surrounding land is likely to have increased the trophic status of the lake however, and it is possible that the lake naturally contained a less productive habitat, such as lake habitat 3140. The inflowing River Fergus has been impacted by nutrients/organic matter since the 1970s. Fluctuations in lake water level are typical, but can be amplified by activities such as abstraction and drainage in this SAC. Increased water level fluctuations can increase wave action, up-root vegetation, increase turbidity, alter the substratum and lead to release of nutrients from the sediment. The hydrological regime defines the area, distribution and depth of the lake habitat and its constituent/characteristic vegetation zones and communities. Ballyallia Lough demonstrates significant fluctuations in water level and flood area.

5.5 Curraghchase Woods SAC (000174)

Curraghchase Woods SAC is a woodland consisting of both deciduous species and stands of commercial conifers. Lakes, fens and wet grasslands are also present. Inn the woodlands, Beech Fagus sylvatica is the most frequent deciduous species, but Pedunculate Oak Quercus robur, Ash Fraxinus excelsior, Sycamore Acer pseudoplatanus and Hornbeam Carpinus betulus are also present. Spruce Picea sp. and Scots Pine Pinus sylvestris are the commonest conifers. Hazel Corylus avellana scrub and areas of wet woodland Salix spp. also occur. Wet woodland may be the priority habitat [91E0] Alluvial Forests. Alluvial Forests has also been identified as being present several other locations throughout the site including in the north and in the southern part of the site. Channel C1/14/4 of the Maigue Outfall Scheme enters Curraghchase Woods SAC in the east and connects to Askeaton Fen Complex SAC to the south west.



• Alluvial forests with Alnus glutinosa and Fraxinus excelsior (Alno-Padion, Alnion incanae, Salicion albae) [91E0]

• Taxus baccata woods of the British Isles [91J0]

• Rhinolophus hipposideros (Lesser Horseshoe Bat) [1303]

Considering the nature and scale of the proposed works and the nature, extent and COs of the QIs of this SAC, all qualifying features, except for Taxus baccata woods of the British Isles [91J0] are considered to be present within the ZOI of the proposed works. Taxus baccata woods of the British Isles [91J0] are not water dependant, have been identified as being present outside of the ZOI for land and air impacts, and therefore, there is no pathway for impact. They are not considered further for significance of impact.

5.6 Danes Hole, Poulnalecka SAC (000030)

This site consists of a small fossil cave in the banks of the Ahaclare River situated within a wood approximately 4 km west of Broadford, Co. Clare. It is a winter hibernation site and also a mating site of the Lesser Horseshoe Bat. A nearby summer roost for the bat and the commuting routes between the two are also included. The cave ends in a sump, though there is no sign that the water floods other parts of the cave. The cave is located within Poulnalecka Wood, which is a broadleaved wood consisting of Oak Quercus sp., Birch Betula sp. and Holly Ilex aquifolium. This woodland provides important foraging habitat and shelter for the bats. This site is located on the Owenagarney (Ratty) River, within the Tulla-Newmarket on Fergus SH_G_229 groundwater body.



• Caves not open to the public [8310]

• Old sessile oak woods with Ilex and Blechnum in the British Isles [91A0]


Not all qualifying features could be potentially be present in the zone of influence of the proposed works. Old sessile oak woods with Ilex and Blechnum in the British Isles [91A0] are not water dependant and due to the location of this site relative to the proposed works, there are no pathways for impact. They are not considered further for significance of impact.

5.8 East Burren Complex SAC (001926)

This large site incorporates all of the high ground in the east Burren in Counties Clare and Galway and extends south-eastwards to include a complex of calcareous wetlands. A large proportion of this SAC is located within the Ennis SH_G_080 GWB. The area encompasses a range of limestone habitats that include limestone pavement and associated calcareous grasslands and heath, scrub and woodland together with a network of calcareous lakes and turloughs. The site exhibits some of the best and most extensive areas of oligotrophic limestone wetlands to be found in the Burren and in Europe.

Ballyeighter Loughs complex to the east is a large network of calcareous hardwater lakes and turloughs with associated fen, cut-away bog and calcareous marsh habitats. The complex contains many species of plant and animal that are found in areas of fluctuating water levels. The alkaline fen flora is well developed and some of the best and most extensive calcareous swamp fen communities in the country occur within this complex.

The site has an excellent array of turloughs, with at least eight known examples including those at Carran, Knockaunroe, Lough Mannagh, Castle Lough, Lough Aleenaun, Turloughmore, Tulla and Roo. These turloughs represent some of the best examples of this habitat type found in Ireland and display a wide diversity in trophic status, water fluctuations, water retention and vegetation types. The aquatic plant communities are well developed and the rare, Red Data Book species, Mudwort Limosella aquatica, occurs here. This species is listed in the Flora (Protection) Order, 1999. Most of the lakes in the southern part of this site are considered examples of hard water lakes, a type listed in Annex II of the E.U. Habitats Directive.

A narrow band of alluvial woodland occurs along the karstic stream at the north-east corner of Lough Gortlecka. This is considered to be a unique variant of this uncommon woodland type.


Caves are a feature of this site, with four known natural limestone caves showing a variety of formations and passage types. Vigo Cave has one of the best undisturbed cave entrance facies in Ireland and is considered a valuable karst heritage landform. Glencurrane Cave shows some fine phreatic solution features and one passageway, known as “Crinoid Tower” shows an abundance of crinoids which have been etched out by splashing water. Gortlecka Cave and a series of small caves above Lough Inchiquin are other fine examples of this habitat.



• Hard oligo-mesotrophic waters with benthic vegetation of Chara spp. [3140]

• Turloughs [3180]

• Water courses of plain to montane levels with the Ranunculion fluitantis and Callitricho-Batrachion vegetation [3260]

• Alpine and Boreal heaths [4060]

• Juniperus communis formations on heaths or calcareous grasslands [5130]

• Calaminarian grasslands of the Violetalia calaminariae [6130]

• Semi-natural dry grasslands and scrubland facies on calcareous substrates (Festuco-Brometalia) (* important orchid sites) [6210]

• Lowland hay meadows (Alopecurus pratensis, Sanguisorba officinalis) [6510]


• Petrifying springs with tufa formation (Cratoneurion) [7220]





• Euphydryas aurinia (Marsh Fritillary) [1065]



Taking into consideration the nature and scale of the proposed works, not all qualifying features could be potentially be present in the zone of influence of the proposed works as they are not considered water dependant or are located outside of the connecting groundwater body and so, there is no potential pathway for impacts. Further details of this screening assessment for QIs is in Section 3. Therefore, only the following QIs are considered further for significance of impact:

• Hard oligo-mesotrophic waters with benthic vegetation of Chara spp. [3140]

• Turloughs [3180]

Taking into consideration the nature and scale of the proposed works, and the nature, extent and COs of the QIs of this site, not all of the QIs of the site are located within the ZOI of the works. They may be screened out as not being at risk from impact as a result of the works because they are located a sufficient distance away from the works to not be impacted by land and air pathways, they may be located in a specific location only that is not at risk from any impact of the works, or there may not be a groundwater or surface water pathway allowing the transfer of impact. Further details of this screening assessment for QIs can be found in Section 3. Therefore, only the following QIs are considered further for significance of impact.

• Estuaries [1130]

• Mudflats and sandflats not covered by seawater at low tide [1140]

5.11 Moyree River System SAC (000057)

The Moyree River is situated in a sheltered valley on the south-eastern fringe of the Burren, Co. Clare. The SAC is located within the Ennis SH_G_080 GWB. The site includes a number of habitat types, including fen, limestone pavement, caves and alluvial woodland. After the Caher River in the north-west Burren, the Moyree River is the best example of a karstic river in the country. The floating scraw vegetation is unusual as this type of habitat is normally destroyed by dredging operations. The river exhibits an excellent example of nutrient gradients associated with silt deposition.

This site is an internationally important summer roosting and hibernation site for Lesser Horseshoe Bat, a species listed in Annex II of the E.U. Habitats Directive. The bats hibernate in a series of natural limestone river caves in the site. The caves are short, low and wet passages that have developed on the water table below limestone ridges










Considering the nature and scale of the proposed works and the nature, extent and COs of the QIs of this SAC, all qualifying features, except for Limestone pavements [8240], could potentially be present in the zone of influence of the proposed works and therefore they are considered further for significance of impact. Limestone Pavements [8240] are not considered further as they are not connected via water pathways and are of sufficient distance from the area of works to not be at risk of impact from land and air pathways.

6 Appropriate Assessment

6.1 Introduction

The following chapter assesses the screened in Natura 2000 sites in more detail and examines where adverse impacts may arise from the sources of impact identified above. The full impact assessment on these features is below. The screened in Natura 2000 sites are as follows:


















Where potentially significant adverse impacts are identified, avoidance and mitigation measures are proposed to offset these impacts. These are discussed in the following sections.

6.2 Identification of potential sources of Impact

This section further examines the source > pathway > receptor chains that could potentially result in adverse impacts arising on the screened in Natura 2000 sites in the Lower river Shannon Arterial Drainage Scheme; this is informed primarily by Ryan Hanley (Ryan Hanley 2014a). Where relevant, this methodology has been updated. Table 3-9 details which of the possible pathways of impact (i.e. surface water, groundwater, land and air) have been identified as potentially affecting each of the screened in Natura 2000 sites.

Figure 3-1, Figure 3-2 and Figure 3-3 illustrates which of the channels and structures within the Lower River Shannon Arterial Drainage Scheme are those which could potentially impact upon the identified Natura 2000 sites, relative to Natura 2000 sites within the Zone of Influence of the works and are consequently screened into the assessment. All other channels and structures within the Lower River Shannon Arterial Drainage Scheme have been screened out of the assessment.

6.2.1 Identification of Potential Sources of Impact via Surface Water Pathways

The following Natura 2000 sites were identified in the AA Screening (Section 3) as potentially being significantly adversely impacted upon by drainage maintenance activities via surface water pathways:








Not all qualifying interests in the SACs were identified as potentially being at risk from sources of impact via surface water pathways as shown in Table 3-3 and Table 3-4. Water dependant qualifying interests, that are not surface water dependant, but which may have connectivity to surface water pathways were also included in these tables, although they may have originally been screened out in the 2014 screening assessment. The following sources of impact are identified as potentially impacting upon the above Natura 2000 site through surface water pathways:

• Release of suspended solids - this can arise from a variety of drainage maintenance activities, including removal of in-stream silt and vegetation, aquatic vegetation cutting, bank protection works and bush cutting, branch trimming and tree cutting. It can impact on surface water dependent habitats and species potentially within the area of works, such as Water courses of plain to montane levels with the Ranunculion fluitantis and Callitricho-Batrachion vegetation [3260], indirectly through increased turbidity, which can reduce photosynthesis levels. This can then impact upon species within the river (i.e. Otter, Salmon or Cormorant) by reducing food availability through changed water quality. Increase in suspended solids can impact on surface water dependent habitats and species such as Schoenoplectus triqueter, Triangular Club-rush and Bryophyte-rich Rivers and Streams, important sub-types of Water Courses of plain to montane levels [3260] in Lower River Shannon SAC. These sub-types are sensitive to increased sediment loads and require high WFD status in terms of nutrients, oxygen, macroinvertebrates and phytobenthos.

• Release or changes in nutrient levels/pollutants - this can arise from a variety of drainage maintenance activities, including removal of in-stream silt and vegetation, aquatic vegetation cutting, bank protection works and bush cutting, branch trimming and tree cutting. It can impact on surface water dependent habitats indirectly through causing eutrophication. This can then impact upon species within the River Shannon and its tributaries within the Scheme (i.e. Otter and Salmon) by reducing food availability through changed water quality. There is also the potential for pollutants (e.g. fuel) to be released from activities with machinery working in or near water as a result of pollution incidents, fuel spillages or poorly maintained machinery. Water quality in wetland areas around lakes and scheme channels, such as those at Tory Hill SAC, vary due to influences of different water types and may be influenced by changes to water chemistry transported by surface water pathways.

• Changes in water levels/channel morphology - this can arise from a variety of drainage maintenance activities, including removal of in-stream silt and vegetation, aquatic vegetation cutting, bank protection works and bush cutting, branch trimming and tree cutting. Removal of vegetation could cause a lowering of the water table within the local area, improving drainage to the channels that are connected to waterbodies or wetland habitats, reducing the quality of fen habitat, marsh or wet woodlands that may be present in Curraghchase Woods SAC or Tory Hill SAC. It can occur from maintenance activities that deepen and wide the channel back to the original design level and may impact upon groundwater dependant terrestrial ecosystems, and the protected species that they support if they have connectivity to surface water pathways. This includes Caves not open to the public [8310] and Rhinolophus hipposideros (Lesser Horseshoe Bat) [1303] at Poulnagordon Cave (Quin) SAC. Saltmarsh habitats, including Salicornia and other annuals colonising mud and sand [1310], Atlantic salt meadows (Glauco-Puccinellietalia maritimae) [1330] and/or Mediterranean salt meadows (Juncetalia maritimi) [1410] may be impacted by changes channel morphology. The location, character and dynamic behaviour of saltmarshes are governed by a variety of factors including sediment supply. Changes to sediment supply through alterations to channel morphology, will impact upon the structure and function of these habitats.

6.2.2 Potential Sources of Impact via Land and Air Pathways

The following Natura 2000 sites were identified in the AA Screening (Section 3) as potentially being significantly adversely impacted upon via land and air pathways:








Not all qualifying interests in the SACs were identified as potentially being at risk from sources of impact via land and air pathways as shown in Table 3-6. The following sources of impact are identified as potentially impacting upon the above Natura 2000 sites through land and air pathways:

• Physical disturbance of habitats (including loss of wood vegetation cover and disturbance to habitats) - this can arise from a variety of drainage maintenance activities, including removal of in-stream silt and vegetation, aquatic vegetation cutting, bank protection works and bush cutting, branch trimming and tree cutting. Obtaining access to works areas can also cause physical disturbance to habitats through removal of woody vegetation and tracking of machinery. It can impact on habitats such as Alluvial Woodlands in Curraghchase Woods SAC or Semi-natural dry grasslands and scrubland facies on calcareous substrates (Festuco Brometalia) (*important orchid sites) in Tory Hill directly, although temporarily, as a result of machines tracking along the bankside, accessing the works area and as a result of the deposition of spoil on the bankside. This can result in a direct loss of habitat from in-stream/bankside areas and maintenance access corridors, direct mortalities or the displacement of sensitive species, such as Otter. Physical disturbance of habitats may indirectly impact upon designated habitats, such as Mudflats and sandflats not covered by seawater at low tide [1140] or Saltmarsh [1310], [1330] & [1410], by releasing sediment, debris, and/or nutrients causing changes to water quality as described in Section 6.2.1. It can also indirectly impact on species through machines tracking along the bankside, reducing vegetation as a food source or reducing cover for birds in River Shannon and River Fergus Estuary SPA and Otter in Lower River Shannon SAC.

• Noise and visual disturbance - this can arise from a variety of drainage maintenance activities, including removal of in-stream silt and vegetation, aquatic vegetation cutting, bank protection works and bush cutting, branch trimming, tree cutting and other activities such as gravel removal. It can occur as a result of noise emissions and visual disturbance from machinery and the presence of machine drivers and other OPW staff at the site of works. It can result in the displacement of sensitive species from suitable habitat locations. It is not considered relevant in relation to designated habitat types, although it is relevant for the species which these habitats support, such as Otter or Lamprey spp. for which the Lower River Shannon SAC is designated. Birds within the River Shannon and River Fergus Estuary SPA may be disturbed from their foraging, breeding or resting places by an increase in activity in areas where activity is normally limited to agricultural practises along the coast, however, this is likely to be temporary due to the nature of the proposed work.

6.2.3 Potential sources of Impact via Groundwater Pathways

The following Natura 2000 sites were identified in the AA Screening (Section 3) as potentially being significantly adversely impacted upon via groundwater pathways:






• Corofin Wetlands SPA (004220)



• Dromore Woods And Loughs SAC (000032)










Not all qualifying interests in the SACs were identified as potentially being at risk from sources of impact via groundwater pathways as shown in Table 3-8. The following sources of impact are identified as potentially impacting upon the above Natura 2000 sites through groundwater pathways:

• Release of suspended solids - this can arise from a variety of drainage maintenance activities, including removal of in-stream silt and vegetation, aquatic vegetation cutting, bank protection works and bush cutting, branch trimming and tree cutting. Increase in suspended solids can impact on ground water dependent habitats with surface water connectivity such as Natural eutrophic lakes with Magnopotamion or Hydrocharition-type vegetation [3150] in Dromore Woods and Loughs SAC. A decline in water quality, resulting in a decrease in transparency as a result of the release of suspended solids, may prevent this SAC from reaching its conservation objectives. Increases in turbidity from the release of suspended solids may also reduce light levels under water, reducing phytoplankton composition and biomass and altering water colour.

• Release or changes in nutrient levels/pollutants - this can arise from a variety of drainage maintenance activities, including removal of in-stream silt and vegetation, aquatic vegetation cutting, bank protection works and bush cutting, branch trimming and tree cutting. Impacts from these works may transfer through groundwater pathways to surface water dependant species and habitats and may impact upon groundwater dependant habitats. Release of nutrients can impact Turloughs [3180] in East Burren Complex SAC, as turloughs, being groundwater fed, are typically associated with high water quality. Turlough water quality is defined by a number of parameters, including a low level of nutrients. Typical vegetation communities and abundance of filamentous algae will also be impacted by changes to nutrient levels/pollutants in turloughs.

Impacts may transfer to surface water habitats and species that are connected via groundwater pathways such as the River Shannon. This can then impact upon species within the river (i.e. Otter, Lamprey and Salmon) by reducing food availability through altered water quality. There is also the potential for pollutants (e.g. fuel) to be released from Scheme activities with machinery working in or near water. These pollutants could travel through groundwater pathways, impacting upon groundwater or surface water dependant habitats and species. Water quality in transitional areas around fens in Askeaton Fen Complex SAC, vary due to influences of different water types and may be influenced by changes to water chemistry transported by groundwater pathways.

6.3 Impact Assessment

The main impacts that have the potential to occur as a result of the proposed works on the Lower River Shannon Scheme and its associated embankments and channels, include both temporary impacts which occur during the works and permanent impacts which may occur as a result of the works.

Potential impacts include those that may affect protected fauna listed in Table 6-1 and protected habitats, listed in Table 6-2.

Temporary impacts include those that may affect water quality and physical alterations to habitats, that will recover after the arterial drainage works finish. Permanent impacts include permanent loss of species and habitats, potentially permanent impacts to water quality and physical disturbance resulting in permanent loss of habitat. All potentially significant impacts are assessed to determine if they have the potential to adversely affect the integrity of the site in the following Section 6.2 and Section 6.3. Mitigation measures required for potential adverse impacts that may arise as a result of Scheme works are described in detail in Table 6-3 and in Section 7.

6.3.1 Do nothing impact

Should the Lower Arterial Drainage Maintenance works not be carried out at this site, it is likely that natural succession would occur throughout the location. This is likely to include increased sedimentation in the channels over time, and increased vegetation growth along channel edges and on the islands that may be present instream. Reduction in channel width due to increase size of vegetated islands, may slow the flow of water and cause flooding in susceptible areas during periods of high rainfall. Erosion occurring along the edge of the banks may contribute further to the sediment loading within the Lower River Shannon SAC. Reduced conveyance within channels may be of benefit to wetlands, bogs and the species that use them, particularly where surface and groundwater pathways are connected.

6.3.2 Cumulative and in-combination impacts

Projects and Plans that have the potential to contribute in-combination impacts and cumulative impacts upon Natura 2000 designated sites are considered in this section, as described in the Guidelines for the Assessment of Indirect and Cumulative Impacts, as well as Impact Interactions (Walker and Johnston 1999). Key points to consider when assessing cumulative and in-combination impacts include the nature and scale of the potential impacts including their potential magnitude and significance, the availability and quality of data, and the impacts that may have occurred with similar projects in the area, where available or observed.

6.3.2.1 Development planning:

Various planning permissions have been granted to projects in the nearby area of the screened in Natura 2000 sites, which have the potential to have similar impacts on water quality, water levels or disturbance as the proposed maintenance works have to the Natura 2000 site. These include the following within the last 5 years:

County Clare

Ballymorris Solar Farm

Applicant: Highfield Solar Limited

Description: This development is located approximately <5km from the Lower River Shannon SAC, directly adjacent to Channel C3 on the Shannon Embankments North Scheme, Sub-Scheme Owenagarney. The development will consist of a 10-year permission for the construction of a Solar PV Energy development within a total site area of up to 9.4 hA, to include one single storey electrical substation building, electrical transformer/inverter station modules, solar PV ground mounted on steel support structures, access roads, fencing, CCTV, and associated electrical cabling, ducting and ancillary infrastructure.

Location: Ballymorris and Garryncurra, Cratloe, Co Clare

Status: Conditionally granted 22/06/2018

Potential for cumulative and/or in-combination impact:

Construction of the site has the potential to contribute temporary noise and visual disturbance, and water quality impacts to QIs of the Lower River Shannon SAC and River Shannon and River Fergus Estuary SAC. An AA Screening has been completed for the site and has determined that there is likely to be no significant adverse impact and an Appropriate Assessment is not required. JBAs brief assessment of the findings of this report do not concur with the AA Screening conclusion. The project works have the potential to have an effect on Natura 2000 sites and require mitigation, therefore a full Appropriate Assessment is required.

Watercrossings will be built as part of the development which are likely to impact upon water quality without appropriate mitigation measures. Mitigation measures included in the report, including those designed to prevent adverse impacts to water quality, have not been assessed for suitability to prevent significant adverse impacts to the COs of the QIs of the nearby Natura 2000 sites that may be within the ZOI of the works and therefore, the potential for significant cumulative and/or in-combination impacts cannot be ruled out.

In summary, there is potential for there to be adverse impacts upon the COs of the QIs of the Lower River Shannon SAC and River Shannon and River Fergus Estuary SPA as a result of this


development and mitigation measures are being implemented to reduce the significance of these impacts. As full Appropriate Assessment has not been completed for this development and it is directly connected via surface water pathways to Natura 2000 sites with water dependant QIs, it is not possible to determine the potential significance of any impacts that may arise as a result of this project. Therefore, it cannot be ruled out that there may be cumulative and/or in-combination impacts upon the Lower River Shannon SAC and River Shannon and River Fergus SPA as a result of this development and the proposed arterial drainage maintenance works. Mitigation measures will be required and are detailed in Table 6-3 and Section 7.

Applicant: Irish Water

Description: For development which will consist of a new inlet works within the boundary of the existing wastewater treatment plant, which is located approximately 4.8km southeast of Shannon Town. The proposed works comprise new inlet works including domestic and industrial balancing tank (0.1218 Ha), an odour control unit and associated services, pipework, screens and flow monitoring equipment. A Natura Impact Statement (NIS) has been prepared as part of this planning application.

Location: Between Embankment E4 and Channel C2 of the Shannon Embankments North Scheme, Bunratty Rineanna Sub-Scheme.

Status: Permission granted 04/12/2014


Impacts identified include those from construction activities that may cause changes to water quality, disturbance to Annexed species from noise and human activities during upgrade works and the potential for the introduction and spread of NNIS. A full NIS has been completed with appropriate mitigation measures recommended to offset the potential adverse impacts.

Therefore, provided the recommended mitigation measures in the NIS are, or have been followed, there is unlikely to be cumulative and/or in-combination impacts upon the Lower River Shannon SAC and River Shannon and River Fergus SPA as a result of this development and the proposed arterial drainage maintenance works.

County Limerick

Applicant: Irish Water

Description: 30 KW of ground mounted solar panels and all associated works

Location: Templeathea West, Athea, Co. Limerick.

Status: Conditional Permission 08/12/2017

Development Description: The construction of a 900 PE wastewater treatment plant and demolition of the existing treatment works. The development will consist of inlet works, a storm tank, treatment works, sludge treatment, a control panel and welfare kiosk, a 2.4m high security fence and a scheme identification sign. Upgrade works to the existing pumping station including the development of a valve chamber, flood gate, internal plant and external finishes. Replacing an existing rising main that extends from the pumping station to the wastewater treatment plant located within regional road R524 with a 475m long rising main. All associated site development and site excavation works above and below ground for the wastewater treatment plant, pumping station and rising main. A Natura Impact Statement has been prepared in respect of this planning application


The AA screening for this development has concluded that the proposed works could impact upon the Lower River Shannon SAC, as well as other Natura 2000 sites not relevant to this assessment. An NIS was conducted. The NIS concludes that provided the recommended mitigation measures are followed, there will be no significant adverse effects on the integrity of the Lower River Shannon SAC and other Natura 2000 sites in the ZOI of these works, either directly, indirectly or cumulatively.

Therefore, it can be considered that provided the mitigation measures for these works are implemented, there is unlikely to be cumulative and/or in-combination impacts upon the Lower River Shannon SAC as a result of this development and the proposed arterial drainage maintenance works.


Applicant: Harry Tobin Sand & Gravel

Description: Extension to existing quarry extraction area, use of mobile crushing & screening plant, a screening berm, landscaping and final restoration of the extracted area to natural habitat, a water management system and all related ancillary activities (quarry reference no. QY 05/7020 and this application is accompanied by an EIS)

Location: Eyon Quarry, Eyon, Cappamore, Co. Limerick

Status: Conditional


The site lies adjacent to the Dooglasha River and areas of marshy grassland that are within the Lower River Shannon SAC. A Natura Impact Statement carried out for the proposed development concludes that the design of the site and control measures set in place that there would be no significant impact upon the Lower River Shannon SAC.

Therefore, provided the design of the site is adhered to and recommended mitigation measures are implemented, there is unlikely to be cumulative and/or in-combination impacts upon the Lower River Shannon SAC as a result of this development and the proposed arterial drainage maintenance works.

Applicant: Engie Developments Ireland Ltd

Description: a ten-year permission to develop a solar farm. The proposed solar farm will comprise the construction and operation of solar PV arrays mounted on metal frames on a 12.1 hectare site, inclusive of a single electrical control building, onsite substation, up to 2 no. inverter units, up to 2 no. temporary construction areas with ancillary facilities, boundary fencing with CCTV units, use of existing access, an access track and all ancillary works (inclusive of gross floor space of proposed works up to 100.4 sqm). The planning application is accompanied by an Environmental Report and stage 1 screening for appropriate assessment

Location: Islandduane, Mungret, Co. Limerick.

Status: Conditional, 30/08/2018

Potential for cumulative and/or in-combination impact: The EIA Report concluded that the proposed development will not result in the loss of habitats and species of high ecological significance and will not have any significant impacts on the ecology of the wider area, as well as no impact on water quality as mitigation measures have been incorporated into the project design.

The Appropriate Assessment Screening has taken into consideration any potential adverse impacts that may occur upon the relevant Natura 2000 sites and their COs. It is concluded that the proposed development, whether individually or incombination with other plans or projects will not have any significant effects on and European Sites. Therefore, there is unlikely to be cumulative and/or in-combination impacts upon the Lower River Shannon SAC as a result of this development and the proposed arterial drainage maintenance works.

Applicant: March Wind Ltd.

Description: a 10-year planning permission for the laying of 4.4 km of underground electrical cables, associated ducting, associated cable draw pits, electrical cabinets, excavation/trenching works, provision of a new substation compound with a single storey substation building and associated services. The underground electrical cable route is primarily on public road with a section on other road. The proposed underground electricity cable will connect the permitted Beennanaspuck Wind Farm and permitted Toberatooreen Wind Farm which are located in County Kerry, to the National Electricity Grid via the Athea substation in County Limerick.

Location: Athea Upper, Athea, Co. Limerick.

Status: Conditional, 27/06/2018

Potential for cumulative and/or in-combination impact: There is potential for impacts from this project on the River Shannon SAC, mainly from groundwater pathway run-off into the Galey River. The EIAR identifies that the cable will pass over 8 streams and rivers which are designated for


salmon, lamprey spp., and otter. During the AA screening it was concluded that the proposed works are not likely to significantly impact any Natura 2000 sites, including the Lower River Shannon SAC. Therefore, there is unlikely to be cumulative and/or in-combination impacts upon the Lower River Shannon SAC as a result of this development and the proposed arterial drainage maintenance works.

Applicant: CPL Fuels Ireland Ltd.

Description: alterations and extension to the existing industrial building, erection of new buildings and new hardcore area for external storage, to accommodate the storage, screening, processing, binding and packaging of solid fuel briquettes by CPL and to use the property for purposes associated with the import and export of products through the Port of Foynes. The proposed development incorporates the construction of two weighbridges, a wastewater treatment system and drainage infrastructure, external lighting, boundary fencing and all ancillary site works. This application is for a 10 year permission. An Environmental Impact Statement and a Habitats Directive Assessment Screening Statement have been prepared in support of the planning application

Location: Lands at Durnish, Internal Port Road, Shannon Foynes Port, Foynes, Co. Limerick.

Status: Permission Conditional 04/11/2014


The AA Screening looked at the potential for impact upon Lower River Shannon SAC, River Shannon and River Fergus SPA, Barrigone SAC, Askeaton Fen Complex SAC and Curraghchase Woods SAC. The screening looks at the potential for cumulative impacts within either the SACs or SPAs occurring within the site area and evaluates that there is no potential for in-combination impacts. The summary of the Screening concludes that the development does not have the potential to give rise to significant effects on the COs of the Lower River Shannon SAC or the River Shannon and River Fergus Estuaries SPA, either individually or in-combination with other plans or projects.

Therefore, there is unlikely to be cumulative and/or in-combination impacts upon the Lower River Shannon SAC as a result of this development and the proposed arterial drainage maintenance works.

Applicant: Bord Na Mona Fuels Limited

Status: Permission Conditional


The Natura 2000 sites considered in the Natura Impact Statement for potential to be impacted by the proposed works on this site included Lower River Shannon SAC, River Shannon and River Fergus SPA, Barrigone SAC, Askeaton Fen Complex SAC and Curraghchase Woods SAC. It was determined that this development, on the basis of the information provided, would not be likely to have a significant effect on the above-mentioned Natura 2000 sites, either individually or in combination with other plans or projects.

Therefore, provided the mitigation measures described in the NIS are implemented, there is unlikely to be cumulative and/or in-combination impacts upon the Lower River Shannon SAC as a result of this development and the proposed arterial drainage maintenance works.


Applicant: Irish Cement Limited

Description: Application for 10 year permission for development to allow for the replacement of fossil fuels through the introduction of lower carbon alternative fuels and to allow for the use of alternative raw materials in their Limerick Cement Factory. To facilitate the on-site handling, storage, and introduction of the alternative fuels and alternative raw materials it is proposed to construct: a tyre storage area with tyre handling/separation area, and associated conveyor kiln 6 with fire water retention tank; a proposed pumpable fluids storage tank which is located within a concrete bund area with associated uploading station all within a 2.4m high security fencing; a proposed fine solids handling building with 2 no. associated truck unloading areas & associated feed conveyors; associated switch room building & associated conveyor from screening building to dosing building at front end of kiln 6, as well as a fine solids transfer building , associated conveyor connecting to a proposed fine solids dosing building to back end of kiln 6 and associated fore-water retention tank; a proposed alternative raw materials storage building with concrete path surround; 3 no. proposed silos for the introduction of free-flowing solids; a proposed by-pass filter comprising a bag filter and a cooling tower with concrete path surround and 1 no. fire-water retention tank. The works include for the demolition of 4 no. steel and metal clad covered car park bay structures. The works also include for associated mechanical equipment and ancillary works, including provision of short sections of internal roadway, pavement, fencing and landscape works. In reducing the quantity of fossil fuel use, the proposed development seeks to introduce a range of alternative fuels up to a maximum of 90,000 tonnes per annum. The use of alternative raw materials is contained within this proposed overall quantity. The application area extends to 10.52 hectares within Limerick Cement Factory (this application relates to an activity for which an Industrial Emissions Licence applies under the Environmental Protected Act 1992, as amended (Industrial Emission Licence Register Number P0029-03. An Environmental Impact Statement accompanies this planning application)

Location: Limerick Cement Factory, Castlemungret.

Status: Conditional Permission 09/04/2017


Conflicting information is provided both within and between the EIS and AA Screening reports produced for this development. The EIS submitted for the proposed development works notes that the development does not occur "under any wildlife or conservation designation", including the EU Habitats Directive. The EIS later acknowledges that River Shannon and River Fergus SPA and Lower River Shannon SAC are at risk of impact from the works and recommends a separate AA Screening is conducted. The EIS acknowledges that runoff and discharges arising from the quarry and cement processes, will enter the River Shannon and River Fergus SPA and the proposed development is located directly adjacent to the Lower River Shannon SAC. No potential impacts upon surface water is envisaged in the EIS, as the Cement Works will continue to be bound by the limits set down in the Industrial Emissions license for the facility. Measures are included to prevent impacts to air quality and water quality during construction. Operational mitigation measures are not required above current operational measures.

The AA screening acknowledges mitigation measures are required during construction to prevent pollution to all waters. In relation to European Sites, the screening in one section states that there will be no adverse impacts and therefore, no mitigation measures are proposed, other than standard best-practise methodologies and site management measures during construction and operation. Table 1 of the AA Screening acknowledges that there are a risk of potential impacts upon the Natura 2000 sites within the ZOI. These are not assessed for significance. Potential impacts that may arise as a result of increased deliveries with larger volumes, and potentially dirty tyres, are not considered. Questions have arisen during the planning process from Limerick City and County Council (LCC) Heritage Officer relating to cumulative effects from deposition of substances or contaminants from the proposed development. The AA screening concludes that there will be no significant negative impacts provided, either alone or in-combination with any other plans or projects and a Stage 2 AA is not required. A full NIS is not conducted so it is not possible to determine if the proposed mitigation measures are sufficient to prevent any potentially significant adverse impacts to the COs of the QIs of the Natura 2000 sites potentially within the ZOI.

Therefore, considering the nature and scale of the proposed works for this development, it's proximity the nearby Natura 2000 sites, the presence of pathways to these sites, that a Stage 2 NIS has not been completed for this development to assess potential significance of effects upon the Natura 2000 sites within the ZOI and the conflicting and insufficient information provided within the


EIS and the AA Screening, it cannot be ruled out that there may be cumulative and/or in-combination adverse impacts upon Natura 2000 sites as a result of this development and the proposed arterial drainage maintenance works. Mitigation measures will be required and are detailed in Table 6-3 and Section 7.

Applicant: Aughinish Alumina Limited

Description: A ten year permission for development on this site of c. 7 hectares located adjoining the existing Aughinish Alumina Ltd plant for the provision of a Borrow Pit with an extraction area of c. 4.5 hectares to extract c. 374.000 m³ of rock over a 10 year period. The extraction area is sought up to a maximum depth of c. 8.5 m O.D., with extraction to occur between April and September each year. The proposed development includes the demolition of a contractors shed and all ancillary site development, areas of stockpiling, landscaping and boundary treatment works above and below ground, including restoration of the extraction area. Aughinish Alumina Limited carries out an activity requiring an Industrial Pollution Prevention and Control Licence (now replaced by an Industrial Emissions Licence – Licence Register No. P0035-06). The development and operation of the proposed Borrow Pit is not a licensable activity. An Environmental Impact Statement (EIS) will be submitted to the Planning Authority with the application.

Location: Aughinish East, Aughinish West, Island Mac Teige, Glenbane West, Morgan North and Fawnamore at or adjacent to Aughinish Island, Askeaton, Co. Limerick.

Status: Permission Conditional 31/01/2018


Appropriate Assessment Screening concludes that by itself, or in combination with other development in the vicinity, the proposed development would not be likely to have a significant effect on the Lower River Shannon SAC, the River Shannon and River Fergus SPA, or any other European Site. A Stage 2 AA was not required. The development will allow for contact with groundwater and mitigation measures will be put in place to ensure that no adverse environmental impacts will occur to underlying hydrogeology as a result of the proposed activities. The potential for impact upon existing ecology and the presence of designated sites within the ZOI is acknowledged in the EcIA and EIS but not within the AA Screening. Therefore, the screening does not fully assess the potential impacts upon the Natura 2000 sites and it is not possible to determine if they are significant impacts.

Therefore, considering the nature and scale of the proposed works for this development, it's proximity the nearby Natura 2000 sites, the presence of pathways to these sites, that a Stage 2 NIS has not been completed for this development to assess potential significance of effects upon the Natura 2000 sites within the ZOI and the conflicting and occasionally lack of information within the EIS and the AA Screening, it cannot be ruled out that there may be cumulative and/or in-combination adverse impacts as a result of this development and the proposed Arterial Drainage Maintenance Works. Mitigation measures will be required and are detailed in Table 6-3 and Section 7.

County Tipperary

Various planning permissions have been granted to projects in County Tipperary, near Newport Town, on the Milkear Ballymeckeogh Scheme C1/1 and the area of the screened in Natura 2000 sites. None of these have the potential to have similar impacts on water quality, water levels or disturbance as the proposed maintenance works have to the Natura 2000 sites.

County Cork

Various planning permissions have been granted to projects in County Cork the nearby area of the Deel Scheme channel C1. None of these have the potential to have similar impacts on water quality, water levels or disturbance as the proposed maintenance works have to the Natura 2000 sites.

Other potential sources of in-combination effects identified as part of this assessment include:


6.3.2.2 Arterial Drainage Maintenance Scheme

Arterial Drainage Maintenance operations have been ongoing since the construction of the schemes following the 1945 Arterial Drainage Act, potentially resulting in adverse cumulative effects. However, as the maintenance operations are undertaken to restore the design level only, the hydrological and hydrogeological impact should be no greater than originally occurred upon the scheme's construction; no further deepening or widening will occur.

On a regional scale, neighbouring Arterial Drainage Schemes could be considered to have an adverse impact on Natura 2000 sites, particularly where large sites fall across two, or more scheme areas. The Lower River Shannon SAC is at risk of impact from both the Lower Shannon Scheme and the Feale Scheme. The Feale Scheme is within a separate surface water catchment and separate groundwater body, however both schemes have their output to the Shannon Estuary and Lower River Shannon SAC. The Feale Scheme NIS has similar mitigation measures proposed as those within this report, to prevent significant adverse impacts to the SACs and therefore, provided the proposed mitigation measures in the Feale Scheme NIS and those proposed in Section 6 and 7 of this report are implemented, it is unlikely that there will be cumulative and/or in-combination adverse impacts as a result of other Arterial Drainage Maintenance Schemes and the proposed Arterial Drainage Maintenance Works on the Lower Shannon Scheme. Mitigation measures will be required and are detailed in Table 6-3 and in Section 7.

6.3.2.3 Agricultural activities in the Lower River Shannon catchment

Farmers and landowners may also undertake general agricultural operations in areas adjacent to the Shannon Estuary and its tributaries, which could potentially give rise to impacts of a similar nature to those arising from the planned OPW works. This could potentially result in additional periods of disturbance and a risk to water quality. Many agricultural operations are periodic, not continuous in nature, and qualify as a Notifiable Action that requires consultation with NPWS in advance of the works e.g. reclamation, infilling or land drainage within 30m of the river, removal of trees or any aquatic vegetation within 30m of the river, and harvesting or burning of reed or willow (NPWS 2018).

Agricultural operations must also comply with the EC (Environmental Impact Assessment) (Agriculture) Regulations 2011 and amendment 2017 S.I. No. 456/2011 and 407/2017 in relation to activities covered by the regulations;

• restructuring of rural land holdings,

• commencing use of uncultivated land or semi-natural areas for intensive,

• land drainage works on lands used for agriculture.

A NIS is required under Regulation 9 if it is likely to have a significant effect on a Natura 2000 site. The drainage or reclamation of wetlands is controlled under the Planning and Development (Amendment) (No. 2) Regulations 2011 and the European Communities (Amendment to Planning and Development) Regulations 2011.

Therefore, the in-combination or cumulative effects of the proposed arterial drainage maintenance works and general agricultural operations upon the screened in Natura 2000 sites is not likely to be significant.

6.3.2.4 River Basin Management Plan 2018 - 2021

Published in April, 2018, the River Basin Management Plan for Ireland 2018-2021 sets out the actions that Ireland will take to improve water quality and achieve ‘good’ ecological status in water bodies (rivers, lakes, estuaries and coastal waters) by 2021 (DoHPLG 2018). Learning from the previous River Basin management plans, for the 2nd Cycle, the Eastern, South Eastern, South Western, Western and Shannon River Basin Districts will be merged to form one national River Basin District. Ireland is required to produce a river basin management plan under the Water Framework Directive (WFD). Water quality in Ireland has deteriorated over the past two decades. The Plan provides a more coordinated framework for improving the quality of our waters — to protect public health, the environment, water amenities and to sustain water-intensive industries, including agri-food and tourism, particularly in rural Ireland.

http://www.housing.gov.ie/water/water-quality/river-basin-management-plans/river-basin-management-plan-2018-2021


The core objectives of the River Basin Management Plan (RBMP) 2018 - 2021 are to prevent deterioration, restore good status, reduce chemical pollution and achieve the water related objectives of protected areas.

The Plan aims to improve the management and water quality of the Shannon International River Basin, and hence in the Shannon Estuary and it's tributaries. Appropriate Assessment has concluded that the RBMP will not adversely affect the integrity of any European site with the implementation of measures presented within the NIS (DHPLG 2018). Any projects that may arise because of the Plan may be subject to individual Appropriate Assessment, that may include assessment of potential cumulative impacts as a result of the works.

Therefore, provided that any works that may occur as a result of the plan are assessed for individually or included in the NIS for the Plan, the Plan should not significantly adversely impact on relevant Natura 2000 sites in combination with the proposed arterial drainage maintenance works.

6.3.2.5 The National Biodiversity Action Plan 2017 - 2021

The objectives of the National Biodiversity Action Plan 2017 - 2021 include the enhancement and conservation of biodiversity. Although such issues would be dealt with at local or site level, the Plan has regard to these objectives and promotes such objectives where possible (DoCHG 2017). Therefore, any potential impacts as a result projects implemented because of this Plan, will be dealt with at local or site level. No significant impacts on European sites, either within out outside the Scheme area are predicted and therefore, there is no risk of significant in-combination or cumulative adverse effects on the screened in Natura 2000 sites, with the proposed arterial drainage maintenance scheme.

6.3.2.6 County Development Plans and Strategies

Limerick County Development Plan 2010 - 2016 (extended) (LCCC 2010), Cork County Development Plan 2014 (2014 - 2020) (CCC 2018), Tipperary County Development Strategy (2014 - 2020) (Tipperary Local Community Development Committee 2014) and Clare County Development Plan 2017 - 2023 (Clare County Council 2017) set out local councils aims, policies and objectives for the proper planning and sustainable development in each county for the relevant time periods.

The purpose of each Development Plan or Strategy, is to set out the overall strategy for the proper planning and sustainable development of the area. The Plans seek to develop and improve, in a sustainable manner, the social, economic, cultural and environmental assets of each county.

Biodiversity Conservation and Management supports are laid out in each Plan and Strategy to support these objectives. All Natura 2000 sites within the considered zone of influence of each Plan, must be assessed for potential to be impacted by each Plan and for there to potentially be in-combination impacts as a result of each Plan. County Development Plans are designed to be taken in conjunction with other similar plans and programmes, to have the overall effect of strengthening the management of and enhancing the protection and conservation of Natura 2000 sites. Specific statements, policies and objectives are formulated within each Plan to allow the Council to take appropriate steps to avoid the deterioration of Natura 2000 sites. Each Plan updates the policies and objectives of the Council in accordance with the Regional Planning Guidelines and National Policy. The outcomes of these Plans are Projects that will in themselves, require specific Natura Impact Assessments where relevant.

Prior to any works commencing on a project that may impact the Natura 2000 network, the project shall be subject to a full Natura Impact Assessment in accordance with the requirements of Article 6(3) of the EU Habitats Directive (Directive 92/43/EEC). This requirement is made explicit in each Plan.

Therefore, provided that any works that may occur as a result of the Plans are assessed for individually or included in the NIS for the Plan, the Plan should not significantly adversely impact on relevant Natura 2000 sites in combination with the proposed arterial drainage maintenance works.

6.3.2.7 Recreational activities on the Shannon Estuary and associated tributaries

The location surrounding the proposed arterial drainage maintenance works in County Limerick, Clare, Cork and Tipperary are a mixture of urban and rural environments. It also covers a large extent of freshwater channels, leading to the coast. A variety of the towns located within or adjacent


to the channels of the Scheme may experience or encourage tourism at various times of the year. Recreational activities that may contribute in-combination or cumulative impacts upon Natura 2000 sites in the ZOI of the Scheme as a result of tourism or recreational activities, include those that contribute to disturbance of QIs, those that may cause a loss of or a reduction in habitat quality, including through the spread of NNIS, and those that may contribute to a reduction in water quality.

In County Clare, the largest tourist areas within the ZOI of the works are in Shannon Airport, Ennis Town and Bunratty. 635,000 overseas tourists and 423,000 Irish Residents visited County Clare in 2016 (Failte Ireland 2018). Shannon Airport is an international airport and in 2017, 1.75 million passengers passed through the airport. Facilities at the airport are equipped to deal with these numbers of passengers, and passengers travel throughout Ireland and beyond, upon arriving in Shannon.

Lough Derg, located on the River Shannon up stream of the area of works, and it's surrounds, are popular for domestic tourists including hillwalkers, nature lovers and water sports enthusiasts. In 2014, 24% of overseas holidaymakers in a Failte Ireland survey visited the Shannon region for hillwalking purposes (Failte Ireland 2016a). Lough Derg hosts a Holiday Village, a marina, tennis courts, restaurant and other facilities. UL Adventure Sport Centre, located on the River Shannon, is owned and run by the University of Limerick Sports Department, catering for students and the general public. Facilities at this location include purpose-built piers, slipways, changing facilities, showers, sauna, kitchen, indoor and outdoor dining areas. The Lough Derg Canoe trail, which is currently undergoing AA, will likely contribute increased tourism numbers to the area. Until the AA is concluded and details become available on the proposed design, further assessment is not possible.

County Limerick had 586,000 overseas tourists and 188,000 Irish Residents visiting in 2016 (Failte Ireland 2018). A new tourism strategy in Limerick City and County envisages that the total number of visitors to Limerick will reach 1.17 million per annum, generating more than €360 million in revenue and creating 1,500 new jobs by 2023. The strategy seeks to optimise the full range of natural and physical assets that provide the foundation for tourism development in the city and county (LCCC 2017). The Strategy is still at Draft stage and a Natura Impact Assessment has yet to be completed. Until the AA is conducted and draft strategy completed, further assessment is not possible.

County Tipperary had 200,000 overseas tourists and 202,000 Irish Residents visiting in 2016 (Failte Ireland 2018). Newport is not considered to be a popular tourist destination and there is unlikely to be significant adverse impacts as a result of tourism or recreational activities from Newport Town in Tipperary.

County Cork had 1377000 overseas tourists and 944,000 Irish Residents visiting in 2016 (Failte Ireland 2018). The Scheme reaches a small area of Cork, through to the town of Milford in North Cork. Milford is not considered to be a significant tourist area and there is unlikely to be any significant adverse impacts as a result of tourism or recreational activities in this area.

Therefore, there is unlikely to be any significant adverse cumulative or in-combination impacts, with the proposed works of the Scheme, as a result of tourism or recreational activities in County Cork or County Tipperary.

However, using the precautionary principle, considering the larger areas of County Limerick and County Clare, the nature, scale and extent of tourism and recreational activities in these areas, given the types of potential impacts including those that may cause disturbance to the QIs of the screened in Natura 2000 sites and/or impact upon water quality and the lack of further information on some recreational development schemes in these areas, there is potential for cumulative disturbance and water quality impacts with this site. Therefore, tourism may significantly adversely impact on the screened in Natura 2000 sites in combination with the proposed arterial drainage maintenance works and further mitigation measures will be required to prevent disturbance and water quality related impacts. Mitigation measures will be required and are detailed in Table 6-3 and in Section 7.

6.3.2.8 Spread of non-native invasive species

Non-native invasive species including Himalayan Balsam, Giant Hogweed and Japanese Knotweed have been recorded around the River Shannon and its tributaries of the lower Shannon Scheme. The density and extent of Giant Hogweed was noted as being particularly high along the Mulkear River and the Mulkear can be considered to be highly contaminated with NNIS. Large, dense areas


of NNIS may replace or reduce the quality of protected habitats or reduce the extent of suitable habitat for protected species.

Other NNIS recorded during the ecological walkover surveys include the aquatic invasives Floating pennywort, Least Duckweed, Canadian waterweed and Common cord-grass in saltmarsh habitats. The NNIS Winter heliotrope Petasites fragrans, Cherry Laurel Prunus laurocerasus, Rhododendron, Buddleia, Montbretia Crocosmia x crocosmiiflora and Snowberry Symphoricarpos albus were all identified as being present within the Scheme works area.

Given the availability of potential transport vectors or pathways, and the large area covered by the Scheme, there is potential for NNIS to be transported between sites within the area of works and from outside of the area of works to within through various external sources including hill walkers/hikers, anglers, dumping and/or illegal turf cutting. Surface water connections, re-use of unclean equipment, machinery or clothing, from nearby projects or developments, or stored nearby in potentially contaminated areas, can all be considered vectors for NNIS. Equipment, machinery or boots that are being used in the water by anglers within potentially contaminated areas could carry microscopic spores, larvae, plant fragments or seeds that if used at this location, can cause the spread of NNIS.

The spread of Crayfish Plague Aphanomyces astaci around Ireland is having detrimental impacts to native crayfish populations and must be prevented (Waterways Ireland 2017). Crayfish are present in the upper reaches of the Shannon and its tributaries. Crayfish Plague has been identified as being present in the Lorrha River, a tributary of the River Shannon and on the River Deel (NBDC 2018). Therefore, Crayfish Plague is present within this Scheme and it can be assumed that any works occurring in the Lower Shannon Scheme may be occurring within water containing Crayfish Plague. Areas where Crayfish Plague is not yet present, will become extremely important to the survival of the infected species. The spread of all NNIS including crayfish plague in particular, must be prevented. Crayfish are QIs of Dromore Woods SAC, Lower River Shannon SAC, East Burren Complex SAC and Moyree River System SAC. They are an important food source for Otter. A reduction in availability of food for Otter may cause a decline in the availability of suitable foraging habitat for Otter. The Spread of Crayfish Plague will prevent the above Natura 2000 sites from reaching their COs.

Crayfish Plague and other NNIS may be transferred on recreational, domestic or commercial equipment, machinery, clothing, vehicles or naturally transferred throughout the various channels of the Scheme.

Therefore, considering the nature, scale and types of non-native invasive species in this area, and given the types of potential impacts there is potential for cumulative decrease in the area of suitable habitats in this site as a result of the spread of non-native invasive species. There is also the potential to prevent Dromore Woods SAC, Lower River Shannon SAC, East Burren Complex SAC and Moyree River System SAC from reaching their COs, if Crayfish Plague spreads further, causing mortalities of the QI White-clawed Crayfish. While the normal operation of the proposed works include the adherence to biosecurity protocol, further, more specific mitigation will be required. Therefore, there may be potential for significant impacts from the proposed arterial drainage maintenance works if they allow for transfer of NNIS in-combination with the transfer of NNIS from a variety of other sources both from within and outside of the Scheme, and further mitigation measures will be required. Mitigation measures are detailed in Table 6-3 and in Section 7.

6.3.2.9 Nutrient enrichment

Potential has been screened in for cumulative and in-combination effects through surface water pathways as a result of eutrophication from agriculture and sewage discharges. Release of nutrients during the works may occur as a result of sediment disturbance in-stream. Given the nature and scale of the works it is not likely to be of an amount to cause significant adverse impacts, however, using the precautionary principle and given that the surrounding landscape is made up of predominantly agricultural land, there is potential for cumulative impacts from agriculture related to eutrophication. Eutrophication caused by increases in nutrient levels in the water, as a result of sediment disturbance and agricultural practises, could cause changes to the vegetative structure and composition in the wetland habitats within the SACs and adverse impacts upon the water quality of the Shannon Estuary and relevant tributaries.


The following wastewater systems are considered to have a potential cumulative and in-combination effects on the Shannon Estuary and its relevant tributaries within the Lower Shannon Scheme:

• The River Mahore, a tributary of the River Shannon in County Limerick, is At Risk from Hospital Town and Environs WWTP. Hospital Town and Environs AER (Irish Water 2017a) confirms that the annual mean and maximum hydraulic loadings are greater than the peak treatment plant capacity. It is listed as a priority area where improvements are needed to resolve environment policies.

• The Foynes agglomeration has a population equivalent (PE) of 1451 and the WWTP present for this agglomeration has a design capacity of 1000. This site is composed of two tidal holding tanks which discharge via outfall pipe into Foynes Harbour, directly connected to the Shannon Estuary SAC (EPA 2018a). There is currently no treatment system for this site. It is listed as a priority where improvements are needed to resolve environment policies and is highlighted as an area that is discharging untreated waste water The AER (Irish Water 2017b).

• There is no Waste Water Treatment Plant WWTP the Clarecastle agglomeration in County Clare. The combined foul and storm water enter the drainage system and flows by gravity to the pumping station on Quay Street. The flow is then discharged untreated to the Fergus Estuary (Irish Water 2017c) (EPA 2018a) . Discharges from Shannon Town WWTP were non-compliant with the Emission Limit Values in 2017 (Irish Water 2017d). . Shannon Town WWTP is listed as a priority plant where improvements are needed to resolve environment policies. The Shannon agglomeration has a population equivalent (PE) of 17,583 but the WWTP has a design capacity of 12,500.

• The River Camogue, a tributary of the River Maigue, is under significant pressure from water pollution as a result of the issues at Herbertstown WWTP (EPA 2018b). This WWTP is to be a priority plant where improvements are needed to meet environmental targets and prevent further impact.

Therefore, there may be significant impacts from the proposed arterial drainage maintenance works in-combination with agricultural practices and through the release of untreated sewage in the area and further mitigation is required. Mitigation measures are detailed in Table 6-3 and in Section 7.

6.3.3 Significance of cumulative and in-combination impacts

In summation, given the nature of the proposed arterial drainage maintenance works, their scale, the local conditions, and considering the same for other relevant plans and projects in this area, it is likely that significant adverse impacts may occur in-combination or cumulatively relative to the Natura 2000 sites Askeaton Fen Complex SAC (002279), Ballyallia Lake SAC (000014), Ballycullinan Lake SAC (000016), Ballyogan Lough SAC (000019), Curraghchase Woods SAC (000174), Danes Hole, Poulnalecka SAC (000030), Dromore Woods and Loughs SAC (000032), East Burren Complex SAC (001926), Glen Bog SAC (001430), Lower River Shannon SAC (002165), Moyree River System SAC (000057), Pouladatig Cave SAC (000037), Poulnagordon Cave (Quin) SAC (000064), Tory Hill SAC (000439), River Shannon and River Fergus Estuaries SPA (004077), Ballyallia Lough SPA (004041) and Corofin Wetlands SPA (004220). Therefore, further mitigation measures in order to prevent the cumulative and in-combination impacts from these impacts are included in Section 7 and in Table 6-3.

6.4 Impact Evaluation

Table 6-3 evaluates the screened in Natura 2000 sites and potential impacts as discussed in Section 6.2 and 6.3.2 in more specific detail and examines where potentially adverse impacts may arise from the sources identified above. Where potentially significant adverse impacts are identified, avoidance and mitigation measures are proposed to offset these impacts.

In Summary, the main potential impacts to the COs of the QIs of Askeaton Fen Complex SAC (002279), Ballyallia Lake SAC (000014), Ballycullinan Lake SAC (000016), Ballyogan Lough SAC (000019), Curraghchase Woods SAC (000174), Danes Hole, Poulnalecka SAC (000030), Dromore Woods and Loughs SAC (000032), East Burren Complex SAC (001926), Glen Bog SAC (001430), Lower River Shannon SAC (002165), Moyree River System SAC (000057), Pouladatig Cave SAC


(000037), Poulnagordon Cave (Quin) SAC (000064), Tory Hill SAC (000439), River Shannon and River Fergus Estuaries SPA (004077), Ballyallia Lough SPA (004041) and Corofin Wetlands SPA (004220)as identified in Section 6.2 are as follows. Those impacts that may be transported through surface water pathways including impacts to water quality that may arise as a result of the release of suspended solids, release or changes in nutrient levels / pollutants, changes in water levels / channel morphology. Potential impacts that may be transported via land and air pathways include physical disturbance of habitats and noise and visual disturbance to species. Potential sources of impact through groundwater pathways include those that may occur through the release of suspended solids and those that occur through the release or changes in nutrient levels/pollutants.

Mitigation measures required to prevent adverse impacts include those described in the OPW EPs. More detailed measures are defined where necessary and are described in detail in Table 6-3 and in Section 7.

Release of suspended solids

Surface water

Fen habitats are influenced by groundwater and surface water connectivity. Habitats with water body connectivity are susceptible to changes in water quality due to the potential release of suspended solids, introduction of pollutants. Changes to water chemistry may not support the natural structure and functioning of the habitats present. Fens are naturally poor in nitrogen and phosphorous, so increases in these levels may alter typical vegetation composition.

Surface water pathways leading to groundwater pathways, impacting upon groundwater dependant habitats may not be visible so follow protocols and EPs in and OPW Environmental Procedures (EP) (OPW 2018) - specifically the procedures under the Environmental Drainage Procedure EP, including compliance with the 10-point plan and auditing processes. Works should follow those as describes in guidance under the Silt Management EP, including but not limited to working upstream, skipping sections and leaving buffer zones both instream and along the banks. Machinery Related Procedures should be followed to include no refuelling within 50m of a watercourse, use of biodegradable oils, ensure availability of spill kits and leave natural vegetation buffer strip along the bank.

In situations where there may be a more significant build-up of silt, debris or nutrients e.g. during sluice maintenance or when clearing channels adjacent to coniferous woodlands or agricultural lands, there will be a 20m section of channel unmaintained at the channel outfall and if this is not naturally present, additional silt mitigation measures will be implemented including the use of geotextiles, clean washed stone and coarse sand (where suitable), removal of material and/or other silt

Release or changes in nutrient levels/ pollutants

No adverse impact

Changes in water levels/ channel morphology

Fens require high groundwater levels and so are also vulnerable to changes in water levels, as they may impact upon the hydrological regime. Surface water flows should be maintained or restored and changes in water levels can prevent this target from being achieved. Drainage lowers the water table and wetland surfaces dry out. This reduces the availability of suitable habitat, alters species diversity and reduces the presence of brown mosses and other typical vascular plant species. Lower water levels may cause peat to compress under its own weight, preventing active peat formation where appropriate.

No adverse impact







filtration techniques. The method used will be on a case-by-case basis and methods used will be documented and discussed with environment team.

Areas adjacent to the SAC in particular on Channels C1/17/4/7 and C1/17/4, should be considered for potential to be wetlands and in these situations, works should follow the Wetland Procedure EP, protect the wetlands hydraulics and minimise or avoid maintenance. No works should occur within fen habitats of Askeaton Fen SAC.

See Table 7-1 Specific mitigation measures for further mitigation measures.

The above measures will control sediment mobilisation and reduce the risk of pollution incidents thereby reducing the potential significance of this source of impact, including cumulative and/or in-combination impacts, on the fen habitats within this SAC, that may be occur through surface water pathways. The above measures will also prevent any changes to groundwater levels, preventing impacts that may occur as a result of this potential source of impact.







Noise and visual disturbance

Physical alterations/ disturbance to habitat

Reduction in area or quality of habitats

Land and Air

Disturbance to the fen habitats can cause the spread of negative and non-native invasive species including graminoids such as reed canary-grass Phalaris arundinacea and reed sweet-grass Glyceria maxima, tall herbs such as great willowherb Epilobium hirsutum, bracken Pteridium aquilinum, bramble Rubus fruticosus and common nettle Urtica dioica, and bryophytes such as Brachythecium rutabulum and Kindbergia praelonga. Cumulative and/or in-combination impacts may arise as a result of the disturbance to stands of NNIS, including Japanese knotweed, that may already be present. A reduction in habitat quality due to an increase in availability of susceptible bare ground, may leave areas more prone to infestation with NNIS.

Physical alterations to fen habitat may occur indirectly through increased drainage causing drying out of habitats, or directly to habitats as the area of works is located directly adjacent to the SAC on Channels C1/17/4/7 and C1/17/4. Physical alterations to the fen habitats may cause a reduction in the area or quality of habitats present, increasing negative indicator species present, reducing the presence of elements of local distinctiveness such as notable flora and fauna, or features of hydrological interest.

Limit works and physical disturbance to habitats around Askeaton Fen SAC, in particular on Channels C1/17/4/7 and C1/17/4, to prevent deterioration of supporting wetland habitat. No works to occur within wetland habitats on these Channels to prevent impacts to potential Fen habitats.

Follow biosecurity procedures as defined in the EP on Spread of Invasive Plant (Low Biosecurity) Procedure, prior to working within or adjacent to Askeaton Fen SAC at all times.

See Table 7-1 for further measures.

The above measures should reduce disturbance to Askeaton Fen SAC, prevent physical disturbance and alterations to important habitats including a reduction in area or quality of these habitats and prevent adverse effects that may arise through cumulative and/or in-combination impacts.

No adverse impact







Release of nutrients

Deepening and widening of channel to original design level


Groundwater Changes to water levels in general, may impact upon habitats such as fens and associated supporting habitats that require high groundwater levels. Drainage lowers the water table and wetland surfaces dry out. This reduces the availability of suitable habitat, alters species diversity and reduces the presence of brown mosses and other typical vascular plant species.

These protected habitats are also susceptible to changes in water quality as a result of the release of suspended solids, introduction of pollutants or changes to nutrient levels transferred through groundwater pathways. As with surface water impacts, they area also vulnerable to changes in water levels or channel morphology impacting upon the hydrological regime. Cover of typical species may be reduced or altered causing a reduction in habitat quality. Changes in water levels may cause pools to drain, impacting on indicators of local distinctiveness which includes in this SAC, the Critically Endangered water beetle Hygrotus decoratus and also the Near Threatened Hydroporus scalesianus, a water beetle indicative of undisturbed fens (NPWS 2018a).

As identified in mitigation measures for surface water pathways, groundwater pathways may not be visible so follow the procedures under the Environmental Drainage Procedure EP, including compliance with the 10-point plan and auditing processes. Works should follow those as describes in guidance under the Silt Management EP, including but not limited to working upstream, skipping sections and leaving buffer zones both instream and along the banks. Machinery Related Procedures should be followed to include no refuelling within 50m of a watercourse, use of biodegradable oils, ensure availability of spill kits and leave natural vegetation buffer strip along the bank.

Areas adjacent to the SAC in particular on Channels C1/17/4/7 and C1/17/4, should be considered for potential to be wetlands and in these situations, works should follow the Wetland Procedure EP, protect the wetlands hydraulics and minimise or avoid maintenance. No works should occur within wetland habitats of Askeaton Fen SAC on the above channels in order to prevent potential impacts to Fens.


The above measures will control sediment mobilisation and reduce the risk of pollution incidents thereby







reducing the potential significance of this source of impact, including cumulative and/or in-combination impacts, on the fen habitats within this SAC, that may be occur through groundwater pathways. The above measures will also prevent any changes to groundwater levels, preventing impacts that may occur as a result of this potential source of impact.


Natural eutrophic lakes with Magnopotamion or Hydrocharition - type vegetation [3150]


Groundwater Natural eutrophic lakes with Magnopotamion or Hydrocharition - type vegetation are sustained by specific water qualities including transparency, nutrients, phytoplankton biomass and composition, attached algal biomass and macrophyte status. Acidification, water colour, dissolved organic carbon levels and turbidity may also be impacted by the release of nutrients as the release of nutrients can cause significant changes in water quality which can trigger significant changes throughout a system. This could then impact on habitat area and vegetation composition attributes.

Groundwater pathways may transfer nutrients and allow for changes in water levels within the SAC, impacting upon it's QIs. Groundwater pathways may not be visible so follow the procedures under the Environmental Drainage Procedure EP, including compliance with the 10-point plan and auditing processes. Works should follow those as describes in guidance under the Silt Management EP, including but not limited to working upstream, skipping sections and leaving buffer zones both instream and along the banks. Machinery Related Procedures should be followed to include no refuelling within 50m of a watercourse, use of biodegradable oils, ensure availability of spill kits and leave natural vegetation buffer strip along the bank.

No works will occur within this SAC as part of this scheme.

morphology amplified by drainage. Increased water level fluctuations can increase wave action, up-root vegetation, increase turbidity, alter the substratum and lead to release of nutrients from the sediment. The hydrological regime must be maintained so that the area, distribution and depth of the lake habitat and its constituent/characteristic vegetation zones and communities are not reduced.

Drainage lowers the water table and wetland surfaces dry out. This reduces the availability of suitable habitat, alters species diversity and reduces the presence of brown mosses and other typical vascular plant species.

The above measures will also minimise any changes to groundwater levels, preventing impacts that may occur as a result of this potential source of impact.










Surface Water

Alluvial forests with Alnus glutinosa and Fraxinus excelsior (Alno-Padion, Alnion incanae, Salicion albae) [91E0] may be susceptible to changes in water quality as a result of the release of suspended solids, introduction of pollutants or changes to nutrient levels. They area also vulnerable to changes in water levels or channel morphology.

Alluvial (Wet) Woodlands rely on the height of the water table for maintenance of the woodland in this SAC. Changes to these qualities may cause alterations to flooding regime and/or vegetation zonation. Periodic flooding is essential to maintain alluvial woodlands along river flood plains, but not for woodland around springs/seepage areas. Vegetative composition, community diversity and extent of Alluvial woodlands may also be impacted upon by changes to water levels, availability of nutrients or pollution events.

Cumulative and/or in-combination impacts may arise as a result of the spread of NNIS through surface water pathways. Spread of terrestrial NNIS may occur if fragments of NNIS plant material reached the scheme channels through contaminated equipment, resulting in a decrease in availability of suitable habitats and an increase in the presence of negative

Surface water pathways may transfer suspended solids, nutrients and pollution to the SAC and it's QIs so follow protocols and EPs in and OPW Environmental Procedures (EP) (OPW 2018) - specifically, the procedures under the Environmental Drainage Procedure EP, including compliance with the 10-point plan and auditing processes. Works should follow those as describes in guidance under the Silt Management EP, including but not limited to working upstream, skipping sections and leaving buffer zones both instream and along the banks.

As per the EP on Alluvial (Wet Woodlands), any works that occur within potential Alluvial Woodland, within the Curraghchase Woods SAC should trigger a site-specific ERA. Further assessment may be required. Staff are provided with the locations of protected habitats and species prior to works commencing in each location.

Areas within or adjacent to the SAC, particularly on and near channel C1/14/4, should be assessed for potential to be wetlands and in these situations follow the Wetland Procedure EP, including, but not limited to protecting the wetlands hydraulics and minimising or avoiding maintenance. Bog mats may be required when traversing through wetlands.

The above measures will control sediment mobilisation, prevent changes in water levels and channel morphology, and reduce the risk of pollution incidents thereby reducing the potential significance of this source of direct, indirect, cumulative and/or in-combination adverse impacts on the Curraghchase Woods SAC and its QIs.

Biosecurity measures will be required where NNIS are present. Should aquatic NNIS be identified, follow biosecurity procedures as defined in the







EP on Spread of Water-based Invasives (High Biosecurity) Procedure, prior to working within and when working within the Lower River Shannon SAC at all times. This includes maintaining a demarking a contaminated zone line with bunting and ensuring anyone or any equipment that crosses this line undergoes specific decontamination as described in the procedures. All staff working within these areas must be briefed on the methodology and sign the method statement outlining this procedure. This will ensure that there are no adverse impacts from the spread of aquatic invasive species.

Where NNIS are present, particularly Japanese Knotweed, Himalayan Balsam and Giant Hogweed, follow biosecurity procedures as defined in the EP on Spread of Invasive Plant (Low Biosecurity) Procedure when working within the SAC. This will ensure that there are no adverse impacts from the spread of terrestrial NNIS.

areas that are not normally accessed by the public. Potential winter roosts, if encountered during winter, may include underground structures such as souterrains, cellars, tunnels, ice houses and natural caves. A decline in condition may occur if these structures are disturbed during winter.

Potential summer roosts, if encountered during spring or summer, may include buildings, for example stables, abandoned cottages and farm buildings, attics of large houses, large chimneys of ruined buildings, modern boiler houses, sheds and garages. A decline in condition may occur if these structures are disturbed during spring or summer.

Potential auxiliary roosts, if encountered at any time of the year within or adjacent to this SAC, may include any of the above-mentioned underground structures or buildings. Disturbance and the removal of vegetation from the surrounding habitat may cause a decline in this attributes condition.

Extent of potential foraging habitat may be reduced through removal of vegetation; however, this will not be more than the design standard and will be along linear features already present only.

suitable for Lesser Horseshoe Bats (LHB). Any artificial bat roosts that may be installed to enhance habitats for bats, should take into consideration the specific roosting requirements of this species. Guidance on the selection of suitable additional LHB bat roosts should be sought from a suitably qualified Ecologist or the NPWS where necessary. The following more detailed measures, specific to this site must be considered when working in or adjacent to this SAC.

The targets for this SAC include no decline in the number and condition of various roost types that this QI may utilise. This includes those within and adjacent to the SAC so works that may occur in the surrounding areas must also consider the following:

Should works occur in this SAC during winter, potential winter roost structures including underground structures such as souterrains, cellars, tunnels, ice houses and natural caves should be entirely avoided if encountered. Works should cease entirely in these locations and the environmental team should be contacted for further assessment if complete avoidance is not possible.

Should works occur in this SAC during spring or summer, potential summer roost structures including buildings, for example stables, abandoned cottages







and farm buildings, attics of large houses, large chimneys of ruined buildings, modern boiler houses, sheds and garages should be entirely avoided if encountered. Works should cease entirely in these locations and the environmental team should be contacted for further assessment if works avoidance is not possible.

Prevention of decline in the condition of the above potential summer and winter roosts should prevent any decline in the condition of potential auxiliary roosts.

In order to prevent unnecessary removal of foraging habitat, previous MAC should be used only and vegetation removal should be at a minimum.

Natural eutrophic lakes with Magnopotamion or Hydrocharition - type vegetation [3150]





Groundwater Natural eutrophic lakes with Magnopotamion or Hydrocharition - type vegetation are sustained by specific water qualities including transparency, nutrients, phytoplankton biomass and composition, attached algal biomass and macrophyte status. Acidification, water colour, dissolved organic carbon levels and turbidity may also be impacted by the release of nutrients as the release of nutrients can cause significant changes in water quality which can trigger significant changes throughout a system. This could then impact on habitat area and vegetation composition attributes.

Groundwater Water connected/dependant habitats and species that are QIs of this SAC or are key species of the QIs of this SAC, may be reliant on water quality and water levels to reach their conservation objectives. Specific conservation objectives have not been set for this site and so these have been taken from similar sites where possible and assumed to be similar for impact assessment. Details of each target and attribute used from each site, is included in Appendix A.8.

Hard oligo-mesotrophic waters are sustained by specific water qualities and water level, which is a key aspect of achieving their conservation objectives. The release of nutrients as a result of drainage maintenance activities could adversely impact on water quality of the lake habitats if groundwaters which are connected to the lake habitat, become contaminated through aquifer recharge. This could then impact on habitat area and vegetation composition attributes by increasing availability of what may be limiting

Groundwater pathways are not always visible and may transfer nutrients allowing for changes in water quality within the SAC. Water levels may also be altered through groundwater pathways impacting upon the SACs QIs, so follow protocols and EPs in and OPW Environmental Procedures (EP) (OPW 2018) as described above for surface water impacts - specifically, the procedures under the Environmental Drainage Procedure EP, the Silt Management EP and Machinery Related Procedures.

Turloughs are groundwater dependant and rely on appropriate hydrological regime and nutrient levels. Water quality and vegetation composition may also be altered by changes to nutrients and water levels that may occur through drainage.

Other water dependant habitats that may be connected to groundwater pathways or reliant on groundwater, including Water courses of plain to montane levels, Alkaline Fens, Calcareous fens, Alluvial forests and caves, may be impacted by fluctuating water levels or changes to nutrient levels. Changes to nutrient levels, increases or decreases in water levels can alter species composition in the habitats, alter microclimates, floodplain connectivity and water quality in general where relevant. Therefore, changes to water levels and nutrient levels may prevent the conservation objectives of this site from being achieved for this QI.

are no specific water quality attributes relating to Otter, available fish biomass is an attribute used to assess the conservation status of Otter populations (NPWS 2012a); water quality can be adversely impacted upon by drainage maintenance and associated activities through the release of suspended solids and nutrients/pollutants and this could be transported through groundwater pathways, impacting on fish populations upon which Otter feed.




Surface Water

Alluvial forests with Alnus glutinosa and Fraxinus excelsior (Alno-Padion, Alnion incanae, Salicion albae) [91E0] may be susceptible to changes in water quality as a result of the release of suspended solids, introduction of pollutants or changes to nutrient levels. They are also vulnerable to changes in water levels or channel morphology, particularly on channels C1/25/22/1 and A1/25/11/1A.

Cumulative and/or in-combination impacts may arise as a result of the spread of NNIS through surface water pathways. Spread of terrestrial NNIS may occur if fragments of NNIS plant material reached the scheme channels through contaminated equipment, resulting in a decrease in availability of suitable habitats and an increase in the presence of negative indicator species within the SAC.

more significant build-up of silt, debris or nutrients e.g. during sluice maintenance or when clearing channels adjacent to coniferous woodlands or agricultural lands, there will be a 20m section of channel unmaintained at the channel outfall and if this is not naturally present, additional silt mitigation measures will be implemented including the use of geotextiles, clean washed stone and coarse sand (where suitable), removal of material and/or other silt filtration techniques. The method used will be on a case-by-case basis and methods used will be documented and discussed with environment team.

Works within or adjacent to wetlands around the SAC should follow the Wetland Procedure EP, including, but not limited to protecting the wetlands hydraulics and minimising or avoiding maintenance. Bog mats may be required when traversing through wetlands.

The above measures will control sediment mobilisation, prevent changes in water levels and channel morphology, and reduce the risk of pollution incidents thereby reducing the potential significance of this source of direct, indirect, cumulative and/or in-combination adverse impacts on Glen Bog SAC and its QIs.









Land and Air Alluvial Woodlands in Glen Bog are located to the south of the site, directly adjacent to Channel C1/25/22/1 and A1/25/11/1A. Therefore, they are at risk from physical disturbance and a reduction in area or quality of habitats.

Disturbance to Alluvial Woodlands and a reduction in area or quality of the woodlands caused by the Scheme could cause a decline in the Habitat Area of the site, alter the cover and height of the woodland, change typical species composition and increase the occurrence of negative indicator species on Glen Bog SAC. Negative indicator species that may be introduced or be allowed to take hold due to an increase in bare ground from un planned tree removal within Alluvial Woodland may include Acer pseudoplatanus, Fague sylvatica, Picea stickensis, LArix decidua, Cotoneaster spp., Prunus laurocerasus, Symphoricarpos albus

and Cornus sericea (O’Neill and Barron 2013).

No works are planned to occur within the Alluvial Woodlands. Any works on channels C1/25/22/1 and C1/25/11/1A will occur on the bank opposite the woodlands and minimal tree maintenance only will occur where necessary on non-alluvial woodland on these channels. As per the EP on Alluvial (Wet Woodlands), any works that occur within potential Alluvial Woodland i,e, within riverside woodlands that flood regularly, within an SAC should trigger a site specific ERA. Further assessment may be required.

Where protected habitats are present the Wetland EP, Alluvial Woodland EP and Tree management EP should be followed. Works within wetlands, including marsh, bog, swamp and wet grasslands should protect the wetlands hydraulics and minimise or avoid maintenance as per Wetland Procedure EP. Machine/bog mats may be required to prevent unnecessary disturbance.

Works will follow Protocol in the EP for Tree Management Procedures, particularly when removing fallen trees and clearing Machine Access Corridor to minimise physical disturbance during the works.

Biosecurity measures will be required where NNIS are present.

Where NNIS are present, particularly Japanese Knotweed, Himalayan Balsam and Giant Hogweed, follow

They are also vulnerable to changes in water levels or channel morphology.

Release of suspended solids may cause in increase in sediment deposition, potentially altering the structure and function of estuarine habitats. Release of suspended solids are likely to be intermittent in duration but may cause significant cumulative impacts to communities present.

Protected habitats that are water dependant and/or connected such as Alluvial (Wet) Woodlands), Molinia Meadows and Saltmarsh habitats, may rely on water levels and/or channel morphology to maintain or restore the structure and/or function of the conservation objectives of the SAC. Changes to these qualities may increase sediment supply to Salicornia [1310] habitat, Atlantic Salt-meadows [1330] and/or Mediterranean Salt-meadows [1410], causing alterations to flooding regime and/or vegetation zonation.

Nutrient level increases could cause an increase in vegetation growth, blocking light for understory or underwater species and altering species composition of Water courses of plain to montane levels with the Ranunculion fluitantis and Callitricho-Batrachion vegetation that may be present. Eutrophication, caused by discharges or the release of detergents, phosphates or sewage, can cause an increase in algal growth in water, which de-oxygenates the water as it dies off, causing fish kills and smothers the typical vegetation present.

Dolphin) [1349]


within all channels, and Dolphin within the River Shannon Estuary, can be impacted by negative impacts transferred through surface waterbodies. Otter, salmonids and Lamprey species are mobile species and may, provided there are no physical barriers, move to another location should the habitat become unsuitable due to lack of prey species / food, pollution events or changes in water levels causing a reduction in suitability of habitat. In some instances, i.e. extreme pollution events, the scheme works could result in direct mortalities of protected animals or fish, effecting the overall population trend. Multiple Scheme watercourses and embankments are directly within the Lower River Shannon SAC, so any release of suspended solids, nutrients or pollutants, changes in current levels of nutrients or changes to channel morphology / water level, within the SAC, could have direct and/or indirect negative impacts upon the conservation objectives of the qualifying interests of the SAC.

Cumulative and/or in-combination impacts may arise as a result of the spread of NNIS through surface water pathways. The Mulkear in particular is infested with NNIS and these are transported throughout the Lower River Shannon SAC. Spread of aquatic NNIS can cause a reduction in

include checking mapping and reporting of Otter holts on gangers card and maintaining a buffer zone of 20m for general maintenance works. This buffer zone may need to be increased depending on the nature of the works required and it may be necessary to obtain a derogation license prior to works commencing where disturbance of the holt is required. See Otter EP for further measures that will be applied as necessary.

Measures required to prevent the spread further of NNIS in this SAC include strict adherence to the EPs on invasive species and additional measures such as keeping machinery on-site when working on the Mulkear River until full cleaning can be conducted to prevent the spread of minute seeds.







habitat quality and/or a reduction in availability of prey species. Crayfish Plague has been identified on the River Deel on the Deel Scheme, which leads to the Shannon Estuary and the Lorrha River upstream of the Lower River Shannon SAC. As it is spreading throughout Ireland, it may spread to channels on the Shannon Scheme causing mass mortality of this important prey species. Crayfish are not a QI of the Lower River Shannon SAC but they are protected under the Habitats Directive. Reduction in habitat quality through loss of prey species or spread of invasive aquatic vegetation, may cause QIs such as Otter or Salmon, to expend increased energy travelling to new foraging and breeding sites, and an overall reduction in availability of suitable habitats. Spread of terrestrial NNIS may occur if fragments of NNIS plant material reached the River Shannon or its tributaries through contaminated equipment, resulting in a decrease in availability of suitable habitats and an increase in the presence of negative indicator species within the Lower River Shannon SAC.








Land and Air

Species that may be present in the SAC are at risk from noise and visual disturbance as a result of the works of the Scheme.

Otter, Salmon, Lamprey spp. and Dolphin that use the River Shannon and associated tributaries within the SAC, are vulnerable to disturbance related impacts from drainage maintenance activities. Disturbance can include noise from staff and machinery operating in the area, visual disturbances from general daytime movement of people and machinery at work, and physical disturbances that cause alterations to the supporting and protected habitats present. Noise and visual disturbances will be temporary.

Disturbance can cause displacement of protected species, requiring increased energy expenditure. Breeding otter may be sensitive to disturbance year-round. Lamprey will be sensitive to disturbance from April to August and Salmonids will be sensitive to disturbance from October to May. Any unnecessary stresses upon protected species can impact upon the population trends of a species and species distribution.

Cumulative and/or in-combination impacts may arise as a result of the disturbance to stands of NNIS, reduction in habitat quality causing increase in availability of susceptible

Limit works and physical disturbance to wetland habitats around Lower River Shannon SAC, in particular on Embankments and within areas adjacent to the SAC, to prevent deterioration of supporting habitats. Almost all channels and embankments of this scheme are ultimately connected to the Lower River Shannon SAC and so species of conservation interest using these areas may be temporarily disturbed by the works. Surveys have been conducted to identify the potential presence of these and these locations have been provided to the OPW in the form of a GIS layer. Staff will be made aware of the location of any protected species and habitats and the following measures will be applied as per the Environmental Procedures (OPW 2018). Specific environmental procedures are available for Salmonids, Otter, Lamprey, Crayfish, Badger, Birds and Bats, described below where relevant.

Where protected habitats and species are present, follow EPs below, limit works and physical disturbance to prevent deterioration of supporting habitat, prevent deterioration of protected habitats and prevent unnecessary impact to protected species that depend on both protected and unprotected habitats.

required should works be necessary that may impact upon protected habitats or species.

As per Salmonid EP, no works are to occur instream outside of July - September. This may be extended following consultation with IFI and if further impacts affect Salmo salar (Salmon) [1106], a project specific NIS may be required. Consultation should be sought from IFI and/or a suitably qualified ecologist in all instances where there may be potential impacts to salmonids that have not previously been assessed i.e. impacts that may occur on channels not screened into this NIS or works not described and assessed in this NIS.

Specific procedures relevant to Otter as described in the Otter Procedures EP include checking mapping and reporting of Otter holts on gangers card and maintaining a buffer zone of 20m for general maintenance works. This buffer zone may need to be increased depending on the nature of the works required and it may be necessary to obtain a derogation license prior to works commencing where disturbance of the holt is required. See Otter EP for further measures that will be applied as necessary.

Where Lamprey may be present, Lamprey Procedure EP is to be



Physical alterations causing a reduction in area or quality of habitats, can be caused by trampling, extensive removal of vegetation in particular within the SAC and destruction of the composition and structure of the habitats present. Alterations to the structure of protected habitats, including Molinia Meadows, Alluvial Woodlands, Saltmarsh and Floating River Vegetation habitats where present, can cause a reduction in habitat quality. Wetlands including Alluvial Woodlands and Molinia Meadows may be more prone to erosion due to an increase in the presence of bare ground.

A reduction in habitat quality instream may impact upon the conservation objectives, as listed in Appendix A.10, of aquatic species. This includes Salmon and Lamprey spp. in particular as may be unable to leave aquatic areas should obstacles be present. Lamprey spawning habitat and juvenile habitat may be disturbed during vegetation removal or instream

works.

A reduction in habitat quality and physical alterations can also be caused by the introduction of non-native invasive species. Several NNIS have been found within the working area during the walkover survey, they may have been removed, may have spread and further invasives may be revealed during vegetation clearance or they may be introduced by machinery or equipment that is used at another location.

Physical alterations resulting from disturbance or introduction of non-native invasive species, can be temporary or permanent dependant on the nature and extent of the habitat alteration. As previous, alterations to habitats can reduce their area, structure and composition. Habitats that are no longer suitable for qualifying protected species as a result of a reduction in habitat quality, may require species to use extra energy to relocate and therefore, a required increase in foraging. Prey species that may have suffered as a result of the degradation in the habitats, may no longer be present or in sufficient quantities for the protected species for which the site is designated a SAC. As a result, Otter, Salmonids and Lamprey may suffer a reduction in their population trend, population distribution, habitat range and extent (area).

followed. Procedures include observing spoil at a minimum 3 times daily, making note of new observations, inform Foreman of new observations of species and replacing stranded lamprey to a bucket prior to release in a suitable location. If Lamprey are confirmed as present, the detailed procedures in the Lamprey EP will be followed.

Wetland habitats (including saltmarsh and molinia meadows) should be identified on-site prior to works commencing. Works occurring within or adjacent to wetlands, or where access to area of works will require travel through wetlands, the Wetland Procedure EP should be followed, including measures designed to protect the wetlands hydraulics and minimising or avoiding maintenance. Bog mats may be required when traversing through wetlands.

As per the EP on Alluvial (Wet Woodlands), any works that occur within potential Alluvial Woodland, within the Lower River Shannon SAC should trigger a site specific ERA. Further assessment may be required.

Where Floating River Vegetation habitat [3260] may be present, the EP on Floating River Vegetation Habitat and Rare Plants Procedures must be followed. This includes the implementation of a 10m buffer zone







where feasible, retention of untouched sections where not including 1/3 to 1/2 of vegetation.

Where NNIS are present, particularly Japanese Knotweed, Himalayan Balsam and Giant Hogweed, follow biosecurity procedures as defined in the EP on Spread of Invasive Plant (Low Biosecurity) Procedure, prior to working within and when working within the Lower River Shannon SAC at all times. This includes maintaining a 7m buffer zone around infestations, washing of all machinery, equipment and this includes personnel's equipment such as boots. Use of the Invasive Plants Construction Management Plan flow chart should be considered where NNIS are present.

Specific Invasive Plant Treatment Procedures are defined in the OPW 2018 procedures manual. These may be required and should be considered where works are required to proceed within areas containing NNIS.


The above measures should reduce disturbance to the QIs of Lower River Shannon SAC, prevent physical disturbance and alterations to important habitats including a reduction in area or quality of these habitats and prevent adverse effects that may arise through cumulative and/or in-combination







impacts.




Groundwater Water dependant habitats at this site that have direct or indirect groundwater linkages (i.e. through surface water pathways) will be influenced by the release or changes in nutrient levels, if any nutrients released cause changes in the quality of the habitats present at the site. Habitat structure, vegetation composition and area can be impacted by changes to groundwater. Changes to water levels could dry out wetlands, resulting in the habitat no longer providing suitable ecosystem services for species like Otter. This could impact upon the range and distribution of Otter using the habitat.

Quayfield and Poulaweala Loughs supporting coastal lagoon habitats are located within Askeaton (IE_SH_G_010) Karstic GWB and may be impacted by the transfer of nutrients through the GWB, or changes in water levels.

Nutrient level increases could cause an increase in vegetation growth, blocking light for understory or underwater species. Eutrophication, caused by discharges or release of detergents, phosphates or sewage, can cause an increase in algal growth in water, which de-oxygenates the water as it dies off, causing fish kills and smothers the typical vegetation present. A reduction in habitat quality and the availability of suitable prey species can also occur from poisoning as a result of the release of pollutants. Protected Otter or Dolphin that rely on fish, will travel to other locations to find suitable fish, or they may eat poisoned fish, resulting in mortalities. Changes in water levels and channel morphology would also make supporting habitats unsuitable for lamprey and salmonids.

Changes to water levels in general, may impact upon habitats such as fens, caves and associated supporting habitats that require specific groundwater levels. Drainage lowers the water table, potentially altering microclimates in sensitive habitats and wetland surfaces dry out. This reduces the availability of suitable habitat, including those used for roosting, alters species diversity and may reduce the presence of protected species such as Rhinolophus hipposideros (Lesser Horseshoe Bat) [1303] as a result.

Habitat structure, vegetation composition and area can be impacted by changes to groundwater.

Surface water

Fen habitats are influenced by groundwater and surface water connectivity. Habitats with water connectivity are susceptible to changes in water quality as a result of the release of suspended solids, introduction of pollutants or changes to nutrient levels. Changes to water chemistry that may occur, may not support the natural structure and functioning of the habitats present. Fens are naturally poor in nitrogen and phosphorous, so increases in levels of these may alter typical vegetation composition.

Surface water pathways leading to groundwater pathways may not be visible so follow protocols and EPs in and OPW Environmental Procedures (EP) (OPW 2018) - specifically the procedures under the Environmental Drainage Procedure EP, including compliance with the 10-point plan and auditing processes. Works should follow those as describes in guidance under the Silt Management EP, including but not limited to working upstream, skipping sections and leaving buffer zones both instream and along the banks. Machinery Related Procedures should be followed to include no refuelling within 50m of a watercourse, use of biodegradable oils, ensure availability of spill kits and leave natural vegetation buffer strip along the bank.

In situations where there may be a more significant build-up of silt, debris or nutrients e.g. during sluice maintenance or when clearing channels adjacent to coniferous woodlands or agricultural lands, there will be a 20m section of channel unmaintained at the channel outfall and if this is not naturally present, additional silt mitigation measures will be implemented including the use of geotextiles, clean washed stone and coarse sand (where suitable), removal of material and/or other silt filtration techniques. The method used will be on a case-by-case basis and methods used will be documented and discussed with environment team.

Fens require high groundwater levels and so are also vulnerable to changes in water levels, as they may impact upon the hydrological regime. Surface water flows should be maintained or restored and changes in water levels can prevent this target from being achieved. Drainage lowers the water table and wetland surfaces dry out. This reduces the availability of suitable habitat, alters species diversity and reduces the presence of brown mosses and other typical vascular plant species. Lower water levels may cause peat to compress under it's own weight, preventing active peat formation where appropriate.

Areas adjacent to the SAC in particular on Channels C1/23 and C1/23/4, should be considered for potential to be wetlands and in these situations, works should follow the Wetland Procedure EP, protect the wetlands hydraulics and minimise or avoid maintenance. No works should occur within Tory Hill SAC fen habitats. Movement of equipment around Lake Nagirra and associated wetlands may require the use of bog mats to prevent release of suspended solids, nutrients and/or pollutants.


The above measures will control sediment mobilisation and reduce the risk of pollution incidents thereby reducing the potential significance of this source of impact, including cumulative and/or in-combination impacts, on the fen habitats within this SAC, that may be occur through surface water pathways. The above measures will also prevent any changes to groundwater levels, preventing impacts that may occur as a result of this potential source of impact.









Land and Air

Disturbance to the fen habitats can cause the spread of negative and non-native invasive species including graminoids such as reed canary-grass Phalaris arundinacea and reed sweet-grass Glyceria maxima, tall herbs such as great willowherb Epilobium hirsutum, bracken Pteridium aquilinum, bramble Rubus fruticosus and common nettle Urtica dioica, and bryophytes such as Brachythecium rutabulum and Kindbergia praelonga. Cumulative and/or in-combination impacts may arise as a result of the disturbance to stands of NNIS that may already be present or may have been introduced since the ecological surveys. A reduction in habitat quality due to an increase in availability of susceptible bare ground, may leave areas more prone to infestation with NNIS.

Qualifying Interests birds that may be present in the SPA and use the River Shannon and associated tributaries within and adjacent to the SPA are at risk from noise and visual disturbance as a result of the works of the Scheme. Wintering birds within the SPA will already be accustomed to a low level of occasional disturbance due to agricultural activities, shipping activities and tourism, and the Scheme may provide cumulative impacts.

Disturbance can include noise from staff and machinery operating in the area, visual disturbances from general daytime movement of people and machinery at work, and physical disturbances that cause alterations to the supporting and protected habitats present. Noise and visual disturbances will be temporary.

Disturbance can cause displacement of protected species, requiring increased energy expenditure. Breeding Cormorant may be sensitive

Physical alterations to the habitat may occur due to the physical removal of vegetation or the addition of soil to raise and/or level out land which should not occur as part of the proposed scheme but may contribute cumulative impacts from local land maintenance. Physical alteration by the collapse of embankments or coastal edges due to transport of personnel or machinery, could result in a reduction in the extent of suitable foraging habitat available to wintering birds. Removal of the woodland along the shoreline could result in a reduction in the extent of terrestrial habitat available that could normally be used by breeding Cormorant.

7 Avoidance and Mitigation Measures In order to ensure that arterial drainage maintenance works and proposed associated works do not adversely impact on the below Natura 2000 sites, specific mitigation and avoidance measures have been highlighted in Table 6-3 that should be followed, in addition to those listed in the OPW's Environmental Management Protocols and EPs (OPW 2018), in order to offset the identified potential impacts on the Natura 2000 sites; these are detailed in Table 7-1. The Natura 2000 sites with potential for adverse impacts are as follows:


















To ensure that adverse impacts do not arise on the above Natura 2000 sites, and their protected habitats and species as in Table 6-1 and Table 6-2 as a result of normal arterial drainage maintenance works undertaken during the period 2019-2023, all procedures as recommended in the OPW Environmental Procedures Document (OPW 2018) are to be followed, specifically the Annual Program Environmental Procedure EP, the Environmental Risk Assessment Procedure EP, Appropriate Assessment Procedure EP, Structures Construction Procedure EP, Environmental Management Procedure EP and those EPs as further recommended within the management EPs.

To view required site-specific mitigation measures, outside of those described in the OPW Environmental Procedures document, see Section 7.1, Table 7-1.

To view required specific mitigation measures relevant to works that may occur on bridges, sluices and/or structures, see Section 7.2, Table 7-2.

Specific Avoidance and Mitigation Measures



Particular attention is to be paid to measures related to the prevention of transfer of nutrients, silt and pollutants when working on channels C1/17/4/7 and C1/17/4 near Askeaton Fen Complex SAC, C1/25/22/1 and C1/25/22/1A near Glen Bog SAC, C1/23 and C1/23/4 in and near Tory Hill SAC, C1/14/4 in Curraghchase SAC and all channels and embankments within the Lower River Shannon SAC; and when working within groundwater bodies Askeaton (IE_SH_G_010) Karstic GWB, Ennis SH_G_080 GWB and/or Kilkishen SH_G_121 GWB.

All aquatic vegetation or brash cuttings shall be removed from the channel and its bank and placed in an area where they cannot re-enter the water.

The release of large amounts of silt or other debris that has built up over time, e.g. during sluice maintenance or when clearing channels adjacent to coniferous woodlands, must be prevented. In these situations, there will be a 20m section of channel unmaintained at the channel outfall and if this is not naturally present, additional silt mitigation measures will be implemented including the use of geotextiles, clean washed stone and coarse sand (where suitable), removal of material and/or other silt filtration techniques. The method used will be on a case-by-case basis and methods used will be documented and discussed with the environment team.


Works on all channels shall be undertaken in accordance with the Scheme's design standard, in order to prevent any new widening or deepening of a channel.

No machinery will be operating within the river channel.

Physical disturbance of species

Particular attention is to be paid to measures related to the prevention of physical disturbance of species when working on channels C1/17/4/7 and C1/17/4 near Askeaton Fen Complex SAC, C1/25/22/1 and C1/25/22/1A near Glen Bog SAC, C1/23 and C1/23/4 in and near Tory Hill SAC, C1/14/4 in Curraghchase SAC and all channels and embankments within the Lower River Shannon SAC.

Where protected species are present, follow relevant EPs, limit works and physical disturbance to prevent unnecessary impact to protected species that depend on both protected and unprotected habitats. Qualifying interests of all Natura 2000 sites are legally protected outside of the SAC. Derogation licenses may be required should works be necessary that may impact upon protected species.

Works that may occur during winter in and around Curraghchase Woods SAC will consider the potential for any structures such as souterrains, cellars, tunnels, ice houses and natural caves to be winter roosts for Lesser Horseshoe Bats and will be entirely avoided if encountered. Should works occur in Curraghchase Woods SAC during spring or summer, potential summer roost structures including buildings, for example stables, abandoned cottages and farm buildings, attics of large houses, large chimneys of ruined buildings, modern boiler houses, sheds and garages will be entirely avoided if encountered.

Where a new, potential roost is discovered in the above SACs, works will cease entirely in these locations and the environmental team will be contacted for further assessment.

As per Salmonid EP, no works are to occur instream outside of July - September. This may be extended following consultation with IFI and if further impacts may affect Salmo salar (Salmon) [1106], a project specific NIS may be required. Consultation should be sought from IFI and/or a suitably qualified ecologist in all instances where there may be potential impacts to salmonids that have not previously been assessed i.e. impacts that may occur on

channels not screened into this NIS or works not described and assessed in this NIS.

Where necessary, the OPW should consult with suitably qualified ecologists, the NPWS and IFI. This will be necessary where unpredicted impacts may occur to supporting habitats and/or protected species, where works may occur on channels that are not included in this NIS, where mitigation measures may be insufficient due to local conditions or unpredictable, unforeseen circumstances and/or where staff are in doubt as to the application of any of the measures within the EPs, including the identification of supporting habitats and/or species that may be present.

Physical disturbance of habitats

Particular attention is to be paid to measures related to the prevention of physical disturbance of habitats when working on channels C1/17/4/7 and C1/17/4 near Askeaton Fen Complex SAC, C1/25/22/1 and C1/25/22/1A near Glen Bog SAC, C1/23 and C1/23/4 in and near Tory Hill SAC, C1/14/4 in Curraghchase SAC and all channels and embankments within the Lower River Shannon SAC.

Areas adjacent to Askeaton Fen SAC in particular on Channels C1/17/4/7 and C1/17/4, should be considered for potential to be wetlands i.e. "Natural or artificial areas where biogeochemical functions depend notably on constant or periodic shallow inundation, or saturation, by standing or flowing fresh, brackish or saline water" (Irish Planning Legislation, 2011). Limit works and physical disturbance where possible to habitats in general around Askeaton Fen SAC, and Lower River Shannon SAC in particular on Channels C1/17/4/7 and C1/17/4, to prevent deterioration of supporting wetland habitat. Prevent any alterations to fen habitats in and around Askeaton Fen SAC.

Works on Channel C1/23/4 near Tory Hill SAC may occur within the Annex I habitat type Semi-natural dry grasslands and scrubland facies on calcareous substrates (Festuco-Brometalia) (* important orchid sites) [6210], A QI for this site, and/or Hydrophilous tall herb fringe communities of plains and of the montane to alpine levels [6430] which is not a QA for this site. Further, more detailed botanical surveying will be required within this area prior to works commencing on this channel during a more optimal survey period of between June to August.

Drainage maintenance works will not encroach into the protected wetland habitats of Lower River Shannon SAC, Curraghchase SAC, Glen Bog SAC, Tory Hill SAC, River Shannon and River Fergus SPA and Askeaton Fen Complex SAC to limit physical disturbance to these habitats.

Where protected habitats are present, limit works and physical disturbance to prevent deterioration of supporting habitat, prevent deterioration of protected habitats and prevent unnecessary impact to protected species that depend on both protected and unprotected habitats. QIs of this site are legally protected outside of the SAC. Derogation licenses may be required should works be necessary that may impact upon protected habitats.

In order to prevent unnecessary removal of foraging habitat for bats in Curraghchase Woods SAC, previous MAC should be used only and vegetation removal should be at a minimum.

Within all Natura 2000 sites, clearance of MAC or accessing works area through wetlands, will necessitate the usage of bog/machine mats in wet areas and tree clearance will be at a minimum, only where necessary and in accordance with the relevant OPW EP on Tree Management.

Qualifying interests of all Natura 2000 sites are legally protected outside of the SAC. Derogation licenses may be required should works be necessary that may impact upon protected habitats or species.


136

Potential Impact


Where necessary, the OPW should consult with suitably qualified ecologists, the NPWS and IFI. This will be necessary where unpredicted impacts may occur to protected habitats, where works may occur on channels that are not included in this NIS, where mitigation measures may be insufficient due to local conditions or unpredictable, unforeseen circumstances and/or where staff are in doubt as to the application of any of the measures within the EPs, including the identification of protected or supporting habitats that may be present.


Works and access will be restricted to maintenance access corridors.

Particular attention is to be paid to measures related to the prevention of noise and visual disturbance of species when working on channels C1/17/4/7 and C1/17/4 near Askeaton Fen Complex SAC, C1/25/22/1 and C1/25/22/1A near Glen Bog SAC, C1/23 and C1/23/4 in and near Tory Hill SAC, C1/14/4 in Curraghchase SAC and all channels and embankments within the Lower River Shannon SAC.

The need for visual screening will be considered on a case-by-case basis, particularly in River Shannon and River Fergus SPA, if works are prolonged within any coastal areas within winter.

Where protected habitats and species are present, follow species specific EPs and limit works and noise and visual disturbance to prevent unnecessary impact to protected species. Species protected under the Habitats Directive are legally protected outside of their designated Natura 2000 site and within other sites for which they are not designated as a QI. Derogation licenses may be required should works be necessary that may impact through disturbance upon protected species.

As per the Salmonid EP, no works are to occur instream outside of July - September. This may be extended following consultation with IFI and if further impacts onSalmo salar (Salmon) [1106] are possible a project specific NIS may be required.

Other Biosecurity measures when working on the Mulkear Scheme will be strictly adhered to regarding terrestrial NNIS in particular. Machinery will not be removed from the area overnight unless it undergoes strict biosecurity measures including the Clean, Check and Dry procedures to prevent further spread of NNIS.

Biosecurity measures when working on the Deel Scheme will follow the Spread of Water Based invasives (High Biosecurity) Procedure EP to prevent spread of Crayfish Plague. Machinery will not be removed from the area at any time, including overnight unless it undergoes strict biosecurity measures as described in the EP.

On all channels, biosecurity measures will be implemented throughout the works following the OPW's Spread of Invasive Plant (Low Biosecurity) Procedure and Spread of Water Based invasives (High Biosecurity) Procedure as necessary. Although Crayfish plague has not been identified as being present within this catchment at any other locations than those mentioned on the Lorrha and the Deel, given the recent outbreaks of crayfish plague reported around Ireland, the best practice principles of Check-Clean-Dry guidance of the NNSS (NNSS 2017) and IFI biosecurity protocols (IFI 2010) shall be followed during these works, to ensure that crayfish plague and invasive non-native species are not introduced into the working area.

7.2 Mitigation for Bridge/Sluice/Structural Works

As discussed in Section 2.2.3, it is currently unknown where and when structural drainage maintenance operations will be required in relation to bridges. This NIS considers the potential impact of maintenance operations on bridges and other structures on those channels and embankments screened into the assessment. To ensure that adverse impacts do not arise on Natura 2000 sites and their QIs as a result of structural maintenance operations undertaken during the period 2019-2023, all procedures as recommended in the OPW Environmental Procedures Document (OPW 2018) are to be followed; specifically the Annual Program Environmental Procedure EP, the Environmental Risk Assessment Procedure EP, Appropriate Assessment Procedure EP, Structures Construction Procedure EP, Environmental Management Procedure EP and where relevant the Bridge Inspection Form EP.

The following pre-works mitigation checklist as detailed will also be implemented where structural maintenance works will occur:

Table 7-2 Mitigation measures for bridge, sluice and/or structural works

8 Conclusions Taking into consideration the limitations and constraints as identified in Section1.4.5, this Natura Impact Statement details the findings of the Stage 2 Appropriate Assessment conducted to further examine the potential direct and indirect impacts of the proposed arterial drainage maintenance works in the Lower River Shannon Arterial Drainage Scheme on the following Natura 2000 sites:


















The above sites were identified by a screening exercise that identified likely significant effects in relation to Natura 2000 sites within the one of Influence of the proposed works. This screening exercise was conducted following the methodology outlined in Ryan Hanley (2014a), which examines three source > pathway > receptor chains; surface water, land and air, and groundwater pathways. The Appropriate Assessment investigated the potential direct and indirect impacts of the proposed works on the integrity and interest features of the above Natura 2000 sites, alone and in-combination with other plans and projects, considering the site's structure, function and conservation objectives. The three pathways of potential impact were again used as a framework of assessment. Where potentially significant adverse impacts were identified, a range of mitigation and avoidance measures have been stipulated to help offset them. As a result of this Appropriate Assessment it has been concluded, that the avoidance and mitigation measures suggested, the proposed drainage maintenance operations in the Lower Shannon Arterial Drainage Scheme will not have a significant adverse impact on the integrity of the above Natura 2000 sites.

To confirm this conclusion, the following checklist, taken from DEHLG (2009) has been completed.

Conservation objectives: does the project or plan have the potential to:

Y/N

Cause delays in progress towards achieving the conservation objectives of the sites?

N - Following mitigation, no significant adverse residual impacts have been identified that will prevent achievement of the conservation objectives of the assessed sites.

Interrupt progress towards achieving the conservation objectives of the sites?

N - Following mitigation, no significant adverse residual impacts have been identified that will prevent achievement of the conservation objectives of the assessed site.

Disrupt those factors that help to maintain the favourable conditions of the site?

N - Potential adverse impacts via surface water; land and air; and groundwater pathways identified during the screening process can be mitigated against.


140

Conservation objectives: does the project or plan have the potential to:

Y/N

Interfere with the balance, distribution and density of key species that are the indicators of the favourable condition of the site?

N - Potential adverse impacts on the habitats and species of the SACs and SPAs are not expected as impacts can be avoided by implementing the mitigation and avoidance measures detailed.

Other objectives: does the project or plan have the potential to:

Y/N

Cause changes to the vital defining aspects (e.g. nutrient balance) that determine how the site functions as a habitat or ecosystem?

N - Potential adverse impacts from suspended solid and nutrient release are not expected as measures can be included within working protocols to ensure potential impacts are effectively mitigated.

Change the dynamics of the relationships (between, for example, soil and water or plants and animals) that define the structure and/or function of the site?

N - Potential adverse impacts relating to hydrological status and water quality have been identified which could impact on the functioning and dynamics of the site, however, these are not expected to be significant given the mitigation measures detailed to ensure potential impacts are effectively mitigated.

Interfere with predicted or expected natural changes to the site (such as water dynamics or chemical composition)?

N - Potential adverse impacts from changes to the hydrological regime and suspended solid/ nutrient/ pollutant release are not expected as measures are included within working protocols to ensure potential impacts are effectively mitigated.

Reduce the area of key habitats? N - Potential adverse impacts on the habitats of the SACs and SPAs are not expected given the mitigation measures that have been detailed.

Reduce the population of key species? N - Potential impacts to key species of all sites, as listed in Table 6-1, are not expected as impacts can be avoided by implementing the mitigation measures detailed.

Change the balance between key species?

N - Potential impacts to key species for which the SACs are designated or which support key features of the designated habitats of the SACs as listed in Table 6-1, are not expected as impacts can be avoided by implementing the mitigation measures detailed.

Reduce diversity of the site? N - The identified mitigation measures to protect designated habitats and species will ensure that the current diversity of the sites is maintained.

Result in disturbance that could affect population size or density or the balance between key species?

N - Potential impacts to the population size, density or balance of key species are not expected as impacts can be avoided by implementing the mitigation measures detailed.

Result in fragmentation N - The proposed works will be undertaken along existing maintenance access corridors and therefore no fragmentation of habitats will occur.

Result in loss or reduction of key features (e.g. tree cover, tidal exposure, annual flooding etc.)?

N - Potential adverse impacts on SAC and SPA habitats as listed in Table 6-2, are not expected as impacts can be avoided by implementing the mitigation measures detailed so there will be no loss of, or reduction of, key features.
