Section 1: Introduction

1.1. This Preliminary Arboricultural Impact Assessment (AIA) has been prepared by Tyler Grange (TG) on behalf of Patrick Properties Strategic Land Ltd to provide an assessment of existing trees at land off Loxley Road (B6077), Sheffield (hereafter referred to as the ‘site’).

1.2. This report has been guided by the recommendations set out within the British Standard 5837:2012 ‘Trees in Relation to Design, Demolition and Construction – Recommendations’ (hereafter BS5837).

Site Description

1.3. The site covers approximately 26.9 hectares of land along the northern and southern banks of the River Loxley. It is located to the south of Loxley Road (B6077), north-west of Sheffield and can be accessed from Storrs Bridge Lane to the north and from a farm track off Rowell Lane in the east.

1.4. The current and former operational areas are located in the bottom of the valley along the river. A steep wooded slope is present in the south of the site and a more gentle slope and mill pond are located in the north.

1.5. The developed area of the site is relatively level with a number of discreet areas of former and operational industrial use; interconnected by a series of non-adopted roadways and bridges. The disused and semi derelict buildings are associated with the former Hepworth Claypit Factory site which was operational until the 1990’s including a furnace, refractory works and storage units. There is a terrace of five dwellings on site and there is also an existing small business that uses some of the outbuildings and hardstanding. The buildings are largely in a state of disrepair and there is evidence of some anti-social behaviour, notably fly-tipping and graffiti within the site.

1.6. Woodland areas and former industrial workings are the dominant land uses with patches of rough grassland and open hardstanding, including pockets of residential units, workshops and open storage areas.

Scheme Description

1.7. Demolition of existing on-site buildings and structures, new and enhanced community woodland andthe construction of a residential-led mixed-use development comprising residential development, elderly persons accommodation, self-build plots, new and enhanced community infrastructure, new and enhanced landscaping and public realm; vehicular access roads, bus gate and parking areas; accommodation and reinstatement works to retained buildings; site remediation and other associated works.

1.8. For reference, the proposed scheme parameters (Land Use) are included at Appendix 4 to the rear of this report.

Section 2: Arboricultural Planning Context

Arboricultural Planning Policy Context

2.1. Under the Town and Country Planning Act 1990 (as amended) the requirement to consider trees as part of development is a material planning consideration and will be taken into account in the determination of planning applications. Arboricultural planning policy that relates to the Site is set out by policy at a National and Local level.

National Planning Policy

2.2. The NPPF is concerned with the delivery of sustainable development, promoting healthy communities, the importance of Public Rights of Way (PRoW), conserving the natural environment and minimising the impact of development on biodiversity, geodiversity, sensitive landscape and the historic environment.

2.3. Paragraph 170 addresses the need to contribute to and enhance the natural and local environment, including a requirement to consider “recognising the intrinsic character and beauty of the countryside, and the wider benefits from natural capital and ecosystem services – including the economic and other benefits of the best and most versatile agricultural land, and of trees and woodland”. Paragraph 170 includes for “minimising impacts on and providing net gains for biodiversity”.

2.4. Paragraph 171 states that Local planning authorities should “take a strategic approach to maintaining and enhancing networks of habitats and green infrastructure”

2.5. Paragraph 175 states that when determining planning applications, local planning authorities should aim see that “if significant harm to biodiversity resulting from a development cannot be avoided (through locating on an alternative site with less harmful impacts), adequately mitigated, or, as a last resort, compensated for, then planning permission should be refused”.

Local Planning Policy

2.6. The current adopted Sheffield Local Plan comprises the Sheffield Core Strategy (adopted March 2009) and ‘saved’ policies from the Sheffield Unitary Development Plan (UDP) (1998). The Council is preparing a new Local Plan which will be named the ‘Sheffield Plan’. This will guide the future of the city by setting out how and where development will take place up to 2034. Once adopted, it will replace the Core Strategy (2009) and the ‘saved’ policies of the UDP.

Sheffield Core Strategy (adopted March 2009)

2.7. Policy CS73 relates to the Strategic Green Network (which follow the rivers and streams of the main valleys) and seeks to ensure that these areas will be maintained and, where possible, enhanced. The policy states that these will be complemented by a network of more local Green Links and Desired Green Links.

2.8. Policy CS74 relates to Design Principles, where high quality development is expected, which would respect, take advantage of and enhance the distinctive features of the city, its districts and neighbourhoods, including “The topography, landforms, river corridors, Green Network, important habitats, waterways, woodlands, other natural features and open space”.


‘Saved’ Policies from the Sheffield UDP (1998)

2.9. As demonstrated by the Proposals Map which accompanies the UDP (North-West, Area 2), the site lies within an Area of Special Character, Green Belt, an Area of High Landscape Value and an Area of Natural History Interest (partially).

2.10. Policy BE15 relates to the Area of Special Character designation and states that “development which would harm the character or appearance of [….] Areas of Special Character will not be permitted.” In the supporting text of the policy, the description states that Areas of Special Character are intended to give interim protection until designation as Conservation Areas can be considered. All such Areas will be assessed against criteria to determine which should become Conservation Areas which includes “Quality of space between buildings, including contribution of trees and designed or natural landscapes”.

2.11. Map 4 within the UDP illustrates ‘The Green Network’, in which a ‘Green Corridor’ passes through the centre of the site, following the River. Policy GE10 states that “a network of Green Corridors and Green Links will be “Protected from development which would detract from their mainly green and open character or which would cause serious ecological damage.”

2.12. Policy GE15 seeks to ensure that trees and woodland are encouraged and protected by planting, managing and establishing trees and woodland, requiring developers to retain mature trees, copses and hedgerows and replace any lost trees and not permit development which would damage existing mature and ancient woodlands.

Loxley Valley Design Statement Planning Guidelines Supplementary Planning Guidance (21st October 2003)

2.13. This document was drafted by the Loxley Valley Design group in consultation with the development services at Sheffield City Council. Its role is to supplement the policies of the UDP by providing more detailed guidance on design for those preparing planning applications for sites in the Loxley Valley (within which the site sits). Planning guideline 2.1 addresses trees, stating that “individual mature trees or mature groups of trees that contribute to the character of the area and are under threat from development will be identified and protected by Tree Preservation Order”.

Statutory Designations Relating to Arboriculture

2.14. As shown on the Sheffield City Council online map of Tree Preservation Orders (TPOs) and Conservation Areas, TPO Storrs Wood & Beacon Wood (ref. 808/15) covers south eastern corner of the site. This is illustrated on the Tree Constraints Plan (TCP) (ref. 12290/P07b) contained to the rear of this report. As set out within this assessment, no TPO trees will be harmed as a result of the proposed development.

2.15. The site is not located within a Conservation Area.

2.16. As shown on the magic.gov.uk website, (and illustrated on the TCP) the south eastern portion of the site is also identified as Ancient Woodland.


Section 3: Baseline Information

Tree Survey Methodology

3.1 A full tree survey of the site was undertaken in October 2019. The survey was undertaken in accordance with BS5837. For further clarification, please refer to the tree survey explanatory notes in Appendix 1. The survey findings have been utilised to inform the masterplan for the Outline Planning Application.

3.2 In accordance with the above recommendations, the tree survey included all trees within / in influence of the site and the site boundaries that were over 75mm diameter at breast height (dbh). Measured topographical survey data was used to inform the locations and surrounding context of the site’s individual and groups of trees.

3.3 Any trees not included within the topographical survey have been approximated using measurements taken during the tree survey and further informed by aerial photography.

3.4 Stem measurements were taken using a diameter tape. Where this was not possible or reasonably practical, measurements have been estimated by eye. Tree heights have been measured using a digital clinometer application.

3.5 The trees surveyed were visually inspected from ground level only. No invasive investigations or climbing inspections were necessary to confirm visual or audible signs of defect or debility and no tissue or soil samples were undertaken. Where identified, signs of substantial defects or debility appropriate to the pre-development context have been recorded.

3.6 The quality and value of trees have been assessed in accordance with the BS5837 Cascade Chart for Tree Quality Assessment included at Appendix 3. Grading subcategories (1, 2 and 3) included within the Cascade Chart for Tree Quality Assessment are intended to reflect arboricultural, landscape and cultural values respectively.

Tree Survey Summary

3.7 A total of 4no. individual trees and 14no. groups of trees and 3no. areas of woodland were identified during the tree survey of the site.

3.8 Findings for each of the trees surveyed are detailed in the Tree Survey Schedule included at Appendix 2 and the distribution of the surveyed tree cover is illustrated on the TCP included to the rear of this report. The Tree Survey Schedule provides a tabulated record of the trees surveyed, including; species composition, tree dimensions, life stage, physiological and structural condition, and the arboricultural value of each tree and group of trees.

3.9 Tree cover comprises a mature network of canopy coverage across the central watercourse. The site is characterised by woodland tree cover with scattered emergent stock also present throughout the site, with more limited, younger and self-seeded tree cover present across the previously developed / former industrial portions of the internal areas of the site.

3.10 Varying degrees of past and active tree management is evident. Typical observations recorded the general presence of deadwood and minor dieback in some of the trees, most of which appeared to be age related or as a result of crossing laterals or conflict with existing adjoining structures. Much of the surveyed tree stock has been left to naturalise within a largely developed context.


3.11 Overall, there is good age diversity and a mix of high to low canopy specimens; however, on-going management is required to ensure that the best trees have the required space, light and nutrients to thrive. This may require selected thinning and crown reductions to afford clearance from adjoining canopies and buildings.

Tree Grading Categories

3.12 The purpose of categorising surveyed trees based on their arboricultural quality and value was to ensure that the emerging design considered the presence of important trees on the Site so informed decisions are made concerning the removal or retention of trees as a result of the proposals.

3.13 The quality of the trees is described by reference to BS5837 categories for tree classification. In accordance with the recommended survey assessment criteria found in Appendix 3, a synopsis of the surveyed tree stock is provided below.

3.14 Higher value arboricultural resources (Category A) are associated with the southern tracts of woodland cover which provides a verdant backdrop and sense of wooded enclosure to the surrounding incised valleys and water course corridor across the edges of the site. Whilst such trees afford a notable contribution in terms of landscape character / screening, the developed context and evident urban pressures has influenced the form and appearance across much of the stock, downgrading the BS5837 categorisation in some cases.

3.15 Category B trees signify those that provide moderate arboricultural quality and value to the Site. Category B trees are denoted by a Blue tree canopy outline as illustrated on the TCP and this level of classification has often been assigned to trees which attract a higher collective rating than they might as individuals, particularly in terms of their visual appearance where contributing to a cohesive group of trees. Such trees predominantly include those with maturity and good future potential, whilst not representing a tree or groups of trees with notable or distinct arboricultural functions.

3.16 Trees of low arboricultural quality and value (Category C) are denoted by a Grey tree canopy outline as illustrated on the TCP found to the rear of this report. All remaining trees represent largely unremarkable examples of their species and provide limited or transient benefits in the existing site context which may be readily replaced. The integration of Category C trees into the design has been recognised as important where practicable as they contribute to the overall tree cover within the site vicinity, nonetheless, they are of less priority for retention, particularly where their removal benefits to the retention of Category B tree cover. Several of the more naturalised or younger tracts of woodland cover has been downgraded to a Category C valuation, particularly where the influence of previous ground disturbances or naturalised degradation has taken hold.

Root Protection Areas

3.17 The TCP shows the approximate extent of Root Protection Areas (RPAs). The RPAs have been calculated in accordance with the methodology set out in Appendices C and D of BS5837, using the stem diameter dimensions obtained during the Site visits.

3.18 RPAs are considered to contain sufficient rooting volume to ensure the survival of the tree and should be left undisturbed in order to avoid damage to the roots or rooting environment surrounding the tree. The plotted RPAs have therefore informed the design of the proposals where possible. In accordance with BS5837, whilst developing within RPAs should be avoided, special working methods can be adopted to alleviate the RPA disturbance for cases where the development is considered necessary and unavoidable.


Tree Canopies and Shading

3.19 The distribution of tree canopy cover on and within influence of the Site and the principal tree shadow constraints are illustrated on the TCP. Canopies have been plotted at cardinal points for individual and groups of trees.

3.20 The Tree Survey Schedule included at Appendix 2 to the rear of this report lists the vertical clearance from Site ground level to significant tree branching of individual trees. This measurement informs the impacts of accessibility and development beneath tree canopies.

3.21 Canopy shading has been plotted in accordance with BS5837 using the current height of surveyed trees. The indicative shade cast by existing surveyed trees signifies the area within which the amenity interests of shading, available daylight and the proximity of trees to any future Site uses may be impacted upon should a tree be retained as part of development.

3.22 Where shading is unavoidable, the potential adverse impact of shadowing should also be reviewed on balance with the positive aspects of retaining a degree of canopy shade. BS5837:2012 (para. 5.3.4, a) NOTE 1) states that "shading can be desirable to reduce glare or excessive solar heating, or to provide comfort during hot weather. The combination of shading, wind speed/turbulence reduction and evapotranspiration effects of trees can be utilised in conjunction with the design of buildings and spaces to provide local microclimatic benefits".


Section 4: Preliminary Arboricultural Impact Assessment

4.1 This Preliminary Arboricultural Impact Assessment has been undertaken to predict the likely tree losses and impacts in response to the outline development parameters prepared by Urbed (see Appendix 4). Tree losses and impacts associated with the proposed access arrangement are considered definitively given the detailed nature of the proposals. The assessment is informed by a composite of the tree survey findings and the proposed site access drawings prepared by Eddisons.

4.2 In accordance with BS5837, potential tree losses to implement the outline layout and proposed tree removals to accommodate the Link Road are illustrated on the Tree Retention and Removal Plan (Ref. 12290/P09a) (TRRP) located to the rear of this report. Tree removals are also listed in the table below.

Tree Number Description of Loss and Mitigation

Proposed Tree Removals to Accommodate the new Access Arrangement

G13 (Mixed species) Category B and C - partial

Selected removal of trees to accommodate widening, footpath implementation and vis-splays for the new vehicular access from Loxley Road. The route of the access road will utilise an area of existing hardstanding / vehicular access. The losses relate to areas of site-side tree cover. Site side lower crowns of retained trees will need to be lifted in accordance with BS3998:2010 to achieve a footway to lower crown clearance of 2.5m to ensure safe clearance for pedestrians and vehicles.

The survey has not identified any trees of high arboricultural value (Category A) on individual merit within G13, nor any trees of veteran or ancient status in terms of age class across the tree belt. Several trees of good maturity and condition are present, including larger horse chestnut and English oak specimens. The northern portion of the tree belt comprises the more notable trees and the southern portion becomes poorer, overall, in terms of tree quality. It is important to note that the arboricultural value of the tree belt is derived from its collective merit.

The removal of 18 trees is proposed, excluding smaller understory. This includes 11 trees of moderate arboricultural value (Category B) and 7 trees of low arboricultural value (Category C).

As the road is widened past the existing road footprint, it will incur within the Root Protection Areas of trees that will be retained at the edges of the new road footprint. The areas of new hardstanding within the RPAs will need to use a ‘no-dig’ approach, including a sensitive approach to new kerb edges, and the building up of any ground levels utilising stacked cell-web and permeable surfacing for the new footway east of the access road to alleviate the impacts within the RPAs. Such works would be specified as part of a later Arboricultural Method Statement in accordance with BS5837:2012.


Tree Number Description of Loss and Mitigation

In response to the extent of tree removals, the following opportunities for enhancements across the tree group have been identified in terms of mitigation:

• New tree and shrub planting to establish an understorey to the tree belt – to provide ecological benefits as well as a more structured appearance to the tree belt.

• Compensatory planting to the east of the tree belt, particularly to the north where most tree loss will be experienced – to reinstate the structure (i.e. width) of the tree line following removals.

• Removal of lower value trees, particularly those identified to be in significant decline or dead, with direct replacements – to secure the longevity of the overall tree group, which is currently short-lived in parts, particularly to the south.

• New planting to plug existing and new gaps across the tree group – to restore and improve the cohesive appearance of the tree belt.

• Thinning of lower trees to improve the future growth environment of the principal trees being retained.

• Remedial pruning works / management – to improve the longevity of individual trees within the tree belt.

Potential Tree Removals to Accommodate the Outline Scheme Parameters:

0.4 ha of W3 woodland (Mixed species) Category B as a collective grading

Partial removal of tracts of moderate to low value internal tree cover due to conflicts with the proposed residential development parcels. The layout includes the provision of formal and informal public open spaces within the development and retains the vast majority of the site’s network of Green Infrastructure and boundary woodland stock to maintain the verdant character and connectivity between areas of retained mature tree cover.

Opportunities to establish a site-wide soft-landscaping scheme. The areas of retained and proposed public open spaces will provide opportunities for new tree planting internally across the development. The opportunities for new tree planting across the development suggests that an increase in canopy cover could be achieved through this scheme, including active management of tree stock which is currently lacking across the site.

0.14ha of category C G13 tree cover (Mixed species) 0.165ha of category C G8 (Mixed species) 0.7ha of category C G10 (Mixed species) 0.15ha of category C G14 (Mixed species) 0.0875ha of category C G7 (Mixed species) T4 (Ash) Category B


4.3 These worst case tree loss predictions are considered to represent a moderate arboricultural impact, reflecting the quantity and quality of the tree removals and the scope for a further detailed iterative design process as part of the later scheme fix. The social proximity associated with retained trees has been recognised in relation to the potential impacts of shading, canopy growth and seasonal nuisance towards newly occupied buildings. The final orientation, development offsets and boundary treatments of specific units at the interface between retained tree groups and proposed residential parcels will require careful consideration to consider the RPAs of mature trees whilst addressing the shading implications of retained high canopy tree stock.

4.4 Mitigation for the proposed tree loss is addressed at this outline stage via the establishment of Green Infrastructure networks in conjunction with the submitted outline scheme parameters which have been determined through a combination of retention of existing green assets wherever appropriate, and the proposal of new open spaces throughout the site. A summary of the Green Infrastructure opportunities is set out below:

• Retention and enhancement of southern boundary woodland areas and safeguarding of Ancient Woodland and TPO tree stock.

• Retention of the central mature river corridor, incorporating retained tracts of mature tree cover with opportunities to strategically open up section of the river to increase intervisibility whilst re-stocking the embankments in places where greater screening is sought.

• Soft landscaping of proposed play and recreational spaces within the scheme and along the central river corridor, creating green gateways comprising tree planting and wide verges with associated planting.

• The implementation of a soft landscaping scheme across the new residential areas with opportunities to create a hierarchy of green infrastructure of avenue street trees, grass verges, hedgerow planting, bulb planting and street tree planting.

Construction Mitigation

4.5 Central to the mitigation of effects during construction and operation will be the production and implementation of an Arboricultural Method Statement (AMS). The AMS would be prepared as part of the package of detailed planning and design documents in order to demonstrate how the above and below ground structures of retained and proposed trees and hedgerows will be protected during the site preparation and construction phases of the development in accordance with BS5837.

4.6 It is therefore recommended that a full AMS is prepared as part of a reserved matters application or to discharge applicable and suitably worded planning Conditions.

4.7 An AMS will set out a practical and robust strategy for the protection of retained trees for the Site preparation, construction of the proposed new link road and the wider development. An AMS can be agreed in writing with the LPA as part of subsequent reserved matters application and / or through imposition and discharge of suitable planning conditions, and is recommended to include:

• a schedule and specification of any tree works; • specifications for barriers and ground protection; • procedures for any specialist construction techniques or supervised excavations within RPAs; • phasing of work; • an auditable system of site monitoring; and • a Tree Protection Plan.


Conclusion

4.8 A BS5837 tree quality survey and preliminary arboricultural impact assessment has been undertaken to inform the Outline Planning Application at land off Loxley Road in Loxley, Sheffield. The proposed development is likely to require the removal of selected areas of internal tree cover in order to implement the outline development parameters and associated vehicular access arrangement. Such tree cover comprises a mix of moderate value mature trees and an array of lower value groups of naturalised tree cover. Much of the site’s screening vegetation and woodland tree stock of merit will be maintained. Trees are shown as retained where these lie within areas of Green Infrastructure and public open spaces on the submitted scheme parameters (see Appendix 4).

4.9 The assessment of potential tree losses detailed in this report represents a worst-case scenario and will be refined during the later detailed planning and design stages where additional tree retention opportunities can be explored as part of the delivery of a design that addresses site levels, layout, a detailed drainage regime and detailed planting proposals in more detail.

4.10 At this stage, the most significant impact relates to the partial loss of the W3 woodland group in order to accommodate an area of new residential footprint. As part of mitigating the removal of existing tree cover, the indicative parameters include a commitment to implementing a site-wide Green Infrastructure strategy consisting of new green areas of public open space and tracts of retained tree cover. Mitigation opportunities can offer direct tree loss replacement, and wide-spread additional tree establishment through the provision of public open spaces, green corridors, formal and informal recreational spaces and associated planting.

4.11 Balancing the potential losses, retention and scope for new green infrastructure within the site, the development parameters are considered to be acceptable in arboricultural terms and demonstrates conformity with local planning policy aspirations pertinent to trees where a network of green and blue linkages will be maintained throughout the site. No Category A, Veteran, TPO or Ancient Woodland trees will be removed as a result of the development.

4.12 In terms of further works recommended for the later detailed planning and design stages, a separate Arboricultural Method Statement would be prepared to accompany a subsequent reserved matter application(s) and / or discharge of suitably worded pre-commencement planning conditions to ensure the safeguarding of retained tree cover during the construction phase of the development.

Land off Loxley Road, Sheffield Preliminary Arboricultural Impact Assessment 12290_R01a_27th February 2020_JJ_MM Appendix 1, Page 1

Appendix 1: Tree Survey Explanatory Notes

Tree Numbers ‘T’ prefixes have been used to identify individual trees and commence with ‘T1’.

‘G’ prefixes have been used to identify groups of trees.

Species Species are listed by their common name, both in the schedule and in the report text.

Height and Stem Diameter The stem diameter of single stemmed trees is measured at 1.5m above ground level and given in millimetres (mm). The diameter measurement of multi-stemmed trees is taken immediately above the root flare. Tree heights are measured in metres (m).

Crown Spread and Height of Crown Clearance Radial crown spread is measured in metres and is listed for each of the four cardinal points. The canopy shape for individually surveyed trees depicted on the accompanying plans accurately represents the canopy spread as measured on-site.

The height crown clearance is measured above ground in metres from the attachment point of the first significant branch, or the height to which the lowest (living) branch reaches; whichever is the lower.

Age Class The age of each tree is defined as follows:

Young - within the first third of life expectancy;

Early-Mature - within the second third of life expectancy;

Semi-Mature - within the last third of life expectancy;

Mature - specimen at full maturity; and

Veteran – tree that, by recognised criteria, shows features of biological, cultural or aesthetic value that are characteristic of, but not exclusive to, individuals surviving beyond the typical age range for the species concerned. For the purpose of this report the term ‘ancient tree’ and ‘veteran tree’ are interchangeable.

Physiological and Structural Condition The physiological or structural condition of each tree is defined as either; good, fair, poor or dead. For each tree, where appropriate, notes on the structural integrity are provided on form, taper, forking habit, storm damage, decay, fungi, pests, etc.

An assessment of a tree’s physiological condition is defined as:

Good – fully functioning biological system showing expectant vitality for the species i.e. normal bud growth, leaf size, crown density and wound closure.

Fair – fully functioning biological system showing below average vitality i.e. reduced bud growth, smaller leaf size, lower crown density and reduced wound closure


Poor – a biological system with limited functionality showing clear physiological decline, disease or significantly below average vitality i.e. limited bud growth, small and chlorotic leaves, low crown density and limited wound closure.

An assessment of a tree’s structural condition is defined as:

Good – no significant structural defects.

Fair – structural defects which could be alleviated through remedial tree surgery or arboricultural management practices

Poor – structural defects which cannot be alleviated through tree surgery or arboricultural management practices.

Limitations

The comments made are based on observable factors present at the time of inspection. Although the health and stability of trees in their current context is an integral part of their suitability for retention, it must be understood that this report is not a tree risk assessment and should not be construed as such. While every attempt has been made to provide a realistic and accurate assessment of the trees’ condition at the time of inspection, it may have not been appropriate, or possible, to view all parts or all sides of every tree to fulfil the assessment criteria of a risk assessment.

No tree can be considered entirely safe, given the possibility that exceptionally strong winds could damage or uproot even a mechanically ‘perfect’ specimen. It is therefore usually accepted that hazards are only recognisable from distinct defects or from other failure-prone characteristics of the tree or the site. An assessment of the potential influence of trees upon existing buildings or other structures resulting from the effects of trees upon shrinkable load-bearing soils or the effects of incremental root or branch growth, are specifically excluded from this report.

Un-assessable Risks

Any alteration to the application site or development proposals could change the current circumstances and may invalidate this report and any recommendations made.

The Wildlife and Countryside Act (WCA) 1981 (as amended) makes it an offence to disturb nesting birds or recklessly endanger a bat or its roost. Bats are also a European protected species and are additionally protected under the Conservation (Habitats & c) Regulations 1994 and 2010 (as amended). The survey findings, constraints, opportunities and design or mitigation recommendations included within that report must be read alongside this document.

A lack of recommended work does not imply that a tree does not pose an unacceptable level of risk and likewise, it should not be implied that a tree will present an acceptable level of risk following the completion of any recommended work.

TREES FOR REMOVAL

Category and Definition Criteria Identification on Plan

Category U Those in such a condition that they cannot realistically be retained as living trees in the context of the current land use for longer than 10 years

• Trees that have a serious, irremediable, structural defect, such that their early loss is expected due to collapse, including those that will become unviable after removal of other category U trees (i.e. where, for whatever reason, the loss of companion shelter cannot be mitigated by pruning).

DARK RED • Trees that are dead or are showing signs of significant, immediate, and irreversible overall decline.

• Trees infected with pathogens of significance to the health and/or safety of other trees nearby or very low-quality trees suppressing adjacent trees of better quality.

(NOTE: Category U trees can have existing or potential conservation value which it might be desirable to preserve)

TREES TO BE CONSIDERED FOR RETENTION

Category and Definition Criteria - Subcategories

Identification on Plan 1. Mainly Arboricultural Values 2. Mainly Landscape Values 3. Mainly Cultural Values, including Conservation

Category A Trees of high quality with an estimated remaining life expectancy of at least 40 years

Trees that are particularly good examples of their species, especially if rare or unusual; or those that are essential components of groups or formal or semi-formal arboricultural features (e.g. the dominant and/or principal trees within an avenue)

Trees, groups or woodlands of particular visual importance as arboricultural and/or landscape features

Trees, groups or woodlands of significant conservation, historical, commemorative or other value (e.g. veteran trees or wood-pasture)

LIGHT GREEN

Category B Trees of moderate quality with an estimated remaining life expectancy of at least 20 years

Trees that might be included in category A, but are downgraded because of impaired condition (e.g. presence of significant though remedial defects, including unsympathetic past management and storm damage), such that they are unlikely to be suitable for retention for beyond 40 years; or trees lacking the special quality necessary to merit the category A designation

Trees present in numbers, usually growing as groups or woodlands, such that they attract a higher collective rating than they might as individuals; or trees occurring as collectives but situated so as to make little visual contribution to the wider locality

Trees with material conservation or other cultural benefits.

MID BLUE

Category C Trees of low quality with an estimated remaining life expectancy of at least 10 years, or young trees with a stem diameter below 150mm

Unremarkable trees of very limited merit or such impaired condition that they do not qualify in higher categories

Trees present in groups or woodlands, but without this conferring on them significantly greater collective landscape value; and/or trees offering low or temporary/transient landscape benefit.

Trees with no material conservation or other cultural value.
