1 INTRODUCTION
1.1 Terms of Reference
1.1.1 Wardell Armstrong LLP (WA) were commissioned by Severn Trent Water Limited to
undertake a Preliminary Ecological Appraisal of the proposed development site
‘Salford Priors, Section 101A’, Warwickshire, approximate central National Grid
Reference: SP 063 520. This report has been produced with reference to current
guidelines for preliminary ecological appraisal (Chartered Institute of Ecology and
Environmental Management (CIEEM 2012)) and British Standard BS 42020:2013 (BSI
2013) which involves the evaluation of potential ecological constraints based on
Extended Phase I (Joint Nature Conservation Committee (JNCC 2010)) survey data and
background desk study.
1.1.2 The purpose of the appraisal is to satisfy the requirements of the National Planning
Policy Framework (NPPF), identifying the likely presence of ecological features within
or near the application site that could pose a constraint to the proposed development.
The following ecological features have been considered:
Statutory and non-statutory designated conservation areas;
UK and local Biodiversity Action Plan (BAP) habitats;
Areas of Ancient Woodland;
Legally protected species;
UK and local BAP species; and
Invasive species.
1.1.3 This report also seeks to identify any requirement for further specialist survey where
the initial assessment cannot be relied upon to adequately determine presence or
reliably infer absence of protected species/taxa. Mitigation and enhancement
opportunities are also discussed.
1.2 Background Information
1.2.1 A previous Extended Phase 1 Habitat Survey was undertaken by Middlemarch
Environmental Limited in 2013 that provided a report in order to advise on any
ecological constraints and mitigation schemes for the site proposals. The data and
conclusions provided by the report are over 24 months old and thus no longer
SEVERN TRENT WATER LIMITED SALFORD PRIORS SECTION 101A, A5S/11519, WARWICKSHIRE PRELIMINARY ECOLOGICAL APPRAISAL
ST13509/001 OCTOBER 2015
Page 2
considered to be valid. This report has been written to provide an updated roster of
data and conclusions to further advise site proposals.
1.2.2 The proposals are for the construction of two pumping stations and a new pipeline
route required to connect residential properties to the two pumping stations.
1.3 Site Context
1.3.1 The area of construction is predominantly hard standing, bordered with rural
residential areas, roadside verges, grassland, farmland and associated farm buildings.
1.3.2 The site follows the road system, stretching from two roads in Dunnington, south to
Iron Cross, and west towards Salford Priors.
1.3.3 The surrounding area comprises expanses of arable farmland and associated
farmsteads and outbuildings.

2 METHODOLOGY
2.1 Desk Study
2.1.1 The desktop study was informed by review of available information provided by
Warwickshire Biological Records Centre (WBRC) and Worcestershire Biological
Records (WBR) for a 2km search radius from the site boundary. Ordnance Survey (OS)
and satellite mapping was also used to gain contextual habitat information.
2.1.2 In order to fully investigate the desk study records for the site, two biological record
centres were contacted as the 2km buffer from the site lies within the jurisdiction of
both records centres.
2.1.3 Specific information was sought for:
Statutory designated sites;
Locally designated sites;
Ancient woodland;
Protected and priority species; and
Local BAP priority species.
2.2 Extended Phase 1 Habitat Survey
2.2.1 Wardell Armstrong LLP carried out an Extended Phase 1 Habitat Survey of the site on
9th September 2015. The survey was carried out by an Ecologist from Wardell
Armstrong LLP. The weather conditions during the survey were around 18⁰C, with
between F1 and F2 wind and 2/8 cloud cover.
2.2.2 The survey followed the ‘Extended Phase 1’ methodology (Institute of Environmental
Assessment (IEA), 1995 and JNCC 2010). Each of the main habitats were classified
according to the relevant criteria.
2.2.3 In addition to the mapping and description of habitats, incidental observations of
protected and/or BAP priority species and the potential for such species to occur on
site (and in the surrounding landscape where relevant) were also noted.
2.2.4 Specific habitat features are mapped on Drawing ST13509/001 with appropriate
reference numbers identifying waterbodies, buildings and trees of particular note.

2.2.5 Comparison and reference to the initial Extended Phase 1 Habitat Survey
(Middlemarch, 2013) has been undertaken to encourage and promote consistency
throughout. Two years have passed since the preliminary survey and the area of
survey has altered. Therefore the initial findings in species, habitats, constraints,
conclusions or recommendations may differ.
2.3 Nomenclature
2.3.1 Vascular plant names follow ‘New Flora of the British Isles’ (Stace 1997) with
vernacular names as provided in the Botanical Society of the British Isles website (BSBI,
2013). All other flora and fauna names following the National Biodiversity Network
(NBN) Gateway (NBN, 2013). The common and scientific name of species/taxa is
provided (if available) when first mentioned in the text, with only the vernacular name
referred to thereafter.
2.4 Assessment Limitations
2.4.1 Ecological surveys are limited by factors that affect the presence of plants and animals
such as time of year, weather, migration patterns and behaviour. The survey was
undertaken in September and therefore the survey data may not be representative of
other times of year.
2.4.2 The absence of desk study records cannot be relied upon to reliably infer absence of
a species/habitat. Often, the absence of records is a result of under-recording within
the given search area.
2.5 Quality Assurance & Environmental Management
2.5.1 All Ecologists employed by WA are members of CIEEM, and are bound by its code of
professional conduct. All surveys and assessments have been undertaken with
reference to the recommendations given in BS 42020.

3 RESULTS AND EVALUATION
3.1 Statutory and Non- Statutory Designated Sites
3.1.1 Desk study results for designated sites within the 2km search radius are evaluated in
Table 1, below.
3.1.2 Sites which are considered potentially sensitive to the development proposals by
virtue of the sensitivity of supported species or habitat assemblages, the
distance/ecological connectivity to the application site and the nature of the
perceived impacts are highlighted in bold text and are discussed in detail in the final
sections of the report.
3.1.3 Sites for which potential adverse effects are not anticipated are excluded from further
assessment.

There are a further 21 non-statutory designated sites within 2km of the site, however they were
not considered to be a constraint as the effects of site proposals are likely to be highly localised
within the surrounding 10m of proposals. These sites have been excluded from this table as they lie
over 1km from the site boundary, additionally, the presence of physical barriers to prevent the
dispersal of protected species towards the site, or the absence of mobile species contributing to the
designation of each site contribute to the site’s exclusion from further assessment.

3.2 Habitats
3.2.1 All habitats within the survey area are described below, together with an indication of
their Biological Action Plan (BAP) status, according to the definitions given in UK BAP
Priority Habitat Descriptions (Anon 2008 updated 2010) and within the Worcestershire
BAP2 and Warwickshire BAP3. The text also provides an evaluation of their potential
to constrain development, indicated with bold text.
3.2.2 Habitats are ordered by occupying area, not in order of ecological importance.
3.2.3 Habitats for which potential adverse effects are not anticipated are excluded from
further assessment.
3.2.4 The location and extent of habitats is shown on Drawing ST13509/001, Extended
Phase 1 Habitat Survey Results.
Habitat Description and Evaluation
Arable farmland
3.2.5 The most dominant habitat in terms of area within and around the site is arable
farmland. Large fields border the site boundary around the peripheries of the majority
of the site, separated from the site boundary only by small roadside verges, arable
field margins, hedgerows, linear woodland blocks or buildings. Species present include
common and widespread crop vegetation including wheat etc. Arable farmland is not
a UKBAP or Local BAP (LBAP) habitat for Warwickshire. Arable farmland is not
considered to pose a potential constraint to development.
Improved grassland
3.2.6 As the second most dominant habitat type in and around the site, improved grassland
occupies several of the fields bordering the site. These are likely the result of rotation
of crop fields for soil and nutrient restoration purposes. Species are limited to a few
select species of coarse grasses and weed species. Improved grassland is not a UKBAP

or LBAP habitat for Warwickshire. Improved grassland is not considered to pose a
potential constraint to development.
Hard standing
3.2.7 Hard standing occupies the majority of the area contained specifically within the site
boundary, as the area of works follows the road system around Iron Cross, Dunnington
and Salford Priors. This comprises predominantly of tarmac or concrete roads,
roadside footpaths and the driveways to residential properties. Hard standing is not a
UKBAP or LBAP habitat for Warwickshire. Hard standing is not considered to pose a
potential constraint to development.
Buildings
3.2.8 There are numerous buildings bordering the site boundary, in all of its northern,
western, southern and eastern extents. The buildings are restricted primarily to
residential uses, although several commercial properties are present throughout the
site. Buildings are not a UKBAP or LBAP habitat for Warwickshire. Buildings are not
considered to pose a potential constraint to development.
Semi-improved grassland
3.2.9 Semi-improved grassland is present in the form of road-side verges along the roads
throughout the site. Various levels of management of the grassland has led to various
sward heights throughout the site. Species include false oat grass Arrhenatherum
elatius, yarrow Achillea millefolium, perennial ryegrass Lolium perenne, clover
Trifolium repens, red fescue Festuca rubra, spear thistle Cirsium vulgare, hogweed
Heracleum sphondylium, creeping thistle Cirsium arvense and ragwort Senecio
jacobaea.
3.2.10 Semi-improved grassland is not a UKBAP habitat, however it is a LBAP habitat within
the Warwickshire BAP under the Roadside Verges habitat action plan (HAP). Habitat
may be lost through site proposals or take accidental damage from site works or
plant. Semi-improved grassland poses a potential constraint to development.

Hedgerows
3.2.11 Species rich intact hedgerows are present on Tothall Lane lining both sides of the road
north of Ban Brook (see Target Notes 1 and 2 on Drawing ST13509-001), comprising
field maple Acer campestre, hawthorn Crataegus monogyna, ash Fraxinus excelsior,
elm Ulmus procera, ivy Hedera helix, alder Alnus glutinosa, rose Rosa sp. and
blackthorn Prunus spinosa.
3.2.12 There are several species poor intact hedgerows throughout the site. The species poor
hedgerows were generally dominated by hawthorn with varying amounts of woody
species distributed through the hedgerow. Species include, but are not limited to,
hawthorn, elder Sambucus nigra, ash, maple Acer sp. with ivy and bittersweet
Solanum dulcamara.
3.2.13 Species poor defunct hedgerows were found bordering several areas of the site,
including New Inn Lane, the B4088 and surrounding arable fields, School Road and
Oakfields track (See Target Notes 3-6 on Drawing ST13509-001), as mentioned in the
Middlemarch Phase 1 Report, 2013. These hedgerows were dominated by hawthorn,
elder and ivy, but also contained ash, maple sp. and cypress Cupressus sp.
3.2.14 Hedgerows are part of both the UKBAP and LBAP. Hedgerows are set to be removed
by site proposals and may also take accidental damage from site works and plant.
Hedgerows pose a potential constraint to development.
Amenity grassland
3.2.15 Within and adjacent to the site lie numerous small areas of amenity grassland in the
form of residential gardens. These are heavily mown, treated and maintained by the
respective owners. These support a very limited array of species, limited to perennial
ryegrass, ribwort plantain Plantago laneolata, daisy Bellis perennis and dandelion
Taraxacum officianale agg.
3.2.16 Amenity grassland is not a UKBAP habitat, however it falls under the ‘Gardens’ HAP
for Warwickshire. Amenity grassland may be damaged or lost through site
proposals. Amenity grassland may pose a potential constraint to development.

Mixed semi-natural woodland
3.2.17 Linear strips of mixed semi-natural woodland are present along the roadside
throughout various locations around the site. These locations include both roadsides
south of Iron cross and along Ban Brook (see Target Notes 7-9 on Drawing ST13509-
001). Species include Norway maple Acer platanoides, robinia Robinia pseudoacacia,
sycamore Acer pseudoplatanus, oak Quercus sp., ash, maple, silver birch Betula
pendula, cherry Prunus sp., willow Salix sp., holly, cypress, cedar Cedrus sp. and scots
pine Pinus sylvestris.
3.2.18 Mixed semi-natural woodland is both a UKBAP and LBAP habitat. Site works are set
to take place within/immediately adjacent to the woodland, resulting in the
potential removal or disturbance of wooded areas. Mixed semi-natural woodland
may pose a constraint to development.
Introduced shrubs
3.2.19 In addition to the amenity grassland, introduced shrubs are present within the
residential gardens located around the site. Species include privet Ligustrum sp.,
buddleia Buddleia sp., cherry laurel Prunus laurocerasus, forsythia Forsythia sp.,
juniper Juniperus communis, kerria Kerria japonica and holly Ilex aquifolium.
3.2.20 Introduced shrubs are not a UKBAP habitat, however they fall under the ’Gardens’
HAP for Warwickshire. Introduced shrubs may be damaged or destroyed through
site proposals. Introduced shrubs may pose a potential constraint to development.
Dense Scrub
3.2.21 Areas of dense scrub are present in throughout various field boundaries, roadside
verges and ditches located around the site. Species include ash, plum Prunus sp., ivy,
bramble Rubus fruticosus, privet and nettle Urtica dioica.
3.2.22 Dense scrub is not a UKBAP habitat, however it is included in the LBAP for
Warwickshire. Dense scrub may be lost through site proposals. Dense scrub may
pose a potential constraint to development.

Arable field margins
3.2.23 Arable field margins are present around the most northerly extent of the site at Tothall
Lane. These are small areas of less maintained vegetation surrounding agricultural
fields, supporting a variety of vegetation and protected species. Species include nettle,
sorrel, cow parsley, field bindweed, hogweed, brassica Brassica sp., oats Avena sativa,
couch grass, broad leaved dock, cocksfoot, ragwort, false oat grass and great
willowherb.
3.2.24 Arable field margins are both a UKBAP and LBAP habitat in Warwickshire. Arable
field margins may be lost through site proposals. Arable field margins may pose a
constraint to development.
Ditch
3.2.25 Three dry ditches lie within the site boundary. One is located along the eastern
boundary of the B4088, extending approximately 100m south of Iron Cross, a second
ditch lies at the western boundary of the B4088 at the New Inn Lane junction, and a
third ditch was found on the eastern section of the southern boundary of New Inn
Lane (See Target Notes 10-12 on Drawing ST13509-001). The dry ditches support
similar plant species to those found within the improved grassland and dense scrub
habitats, these include but are not limited to; perennial ryegrass, false oat grass,
creeping thistle, nettle and bramble.
3.2.26 Additionally, a single wet ditch was located on the northern boundary of Oakfields
Track (See Target Note 13 on Drawing ST13509-001). The water within the ditch was
not flowing, and no submerged or emergent vegetation was recorded.
3.2.27 Though ditches are not a UKBAP habitat, they are a LBAP habitat within
Warwickshire. Ditches may be lost impacted by site proposals. Ditches may pose a
constraint to development.
Scattered trees
3.2.28 Numerous semi-mature and mature trees are located throughout the entire site,
predominantly lining roads adjacent to fields, with other trees located in residential
gardens. Additionally, several trees located within the site were noted to have
features with the potential to support roosting bats. Broadleaved tree species

ST13509/001 OCTOBER 2015
Page 12
recorded include oak, ash, silver birch, willow, cherry, sycamore, field maple,
European chestnut Castanea sativa, robinia and hawthorn. Coniferous species noted
within the site included Corsican Pine Pinus nigra laricio, scots pine, cypress and cedar.
3.2.29 Scatted trees are not a UKBAP, however they fall under the ‘Gardens’ HAP for
Warwickshire. Scattered trees may be lost through site proposals. Scattered trees
may pose a constraint to development.
Watercourse
3.2.30 The watercourse “Ban Brook” was noted running across the site, through a culvert
underneath Tothall Lane and the B4088 (See Target Notes 14 and 15 on Drawing
ST13509-001), bordered by common ruderal species and occasional areas of fen, that
lie away from the site boundary.
3.2.31 Watercourses are both a UKBAP and a LBAP habitat, both of which run through the
site. Watercourses may be impacted by site proposals. Watercourses may pose a
constraint to development.
Waterbodies
3.2.32 There are six waterbodies within 500m of the site boundary (See Target Notes 16-21
on Drawing ST13509-001). The ecologist from WA undertook a Habitat Suitability
Index (HSI) survey of these waterbodies during the Extended Phase 1 Habitat Survey
to discern the waterbodies’ potential to support great crested newts (GCN) Triturus
cristatus.
3.2.33 The waterbodies that lie within 500m of the site boundary are considered to be
suitable to support breeding GCN and are within the terrestrial dispersal range of GCN.
As thus further discussion is needed to assess the impact of development upon the
nature conservation value of GCN within the local area, please refer to section 4.1.39
to Error! Reference source not found..
3.2.34 Waterbodies are both a UKBAP and LBAP habitat, however they lie distant from the
site works and thus are not considered to pose a constraint to development.

Veteran Tree
3.2.35 A veteran oak is present on the roadside at the end of the driveway of Salford Farm
House, NGR: SP 06411 52005 (See Target Note 22 on Drawing ST13509-001).
3.2.36 Veteran trees are both a UKBAP and an LBAP in Warwickshire. The veteran tree may
be impacted by site proposals. Veteran trees are considered a potential constraint
to development.
3.3 Species
3.3.1 Recorded protected and/or invasive species from the field survey or evidence of the
presence of protected or BAP priority species are described below.
Birds
3.3.2 All birds recorded during the survey are summarised in Table 3, below together with
a preliminary assessment of their likelihood to pose a constraint to the development.
All nesting birds are discussed in the final section given the general legislative
provisions relating to destruction of active nests. In addition, potential effects to
species identified as potential constraints due to the presence extent and viability of
supporting habitat, ecological connectivity and perceived nature and extent of effects
also discussed in more detail (species highlighted in bold text) in the discussion
section.

Invasive Plants
3.3.3 During the survey, a small area of Himalayan balsam Impatiens glandulifera was
located next to Ban Brook at NGR: SP 06304 52633 (See Target Note 23 on drawing
ST13509-001). Due to the prolific nature of this species, it is considered likely that this
species is widespread up and downstream throughout a large expanse of Ban Brook.
This may pose a constraint to development if left unchecked in areas where
construction may be taking place i.e. where the Ban Brook intersects with the site.
3.3.4 No other invasive species were noted.
3.4 Ecological Evaluation
3.4.1 Protected, UK & Local Biodiversity Action Plan species are evaluated in order to
identify potential ecological constraints in Table 4 below, based on the desk study
records, presence extent and viability of supporting habitat, ecological connectivity
and perceived nature and extent of effects.
3.4.2 Species/taxa for which potential adverse effects are not anticipated are excluded from
further assessment.

4 DISCUSSION AND RECOMMENDATIONS
4.1 Potential Constraints
4.1.1 The following designated sites, habitats and species (receptors) have been evaluated
as being potential ecological constraints:
Himalayan Balsam;
Ban Brook, headwaters and tributaries LWS;
Semi-improved grassland;
Hedgerows;
Amenity grassland;
Mixed semi-natural woodland;
Introduced shrubs;
Dense scrub;
Arable field margins;
Ditches;
Scattered trees;
Watercourse;
Veteran tree;
Bats;
Badger;
Otter;
Water vole;
Reptiles;
GCN;
Nesting birds (general).
4.1.2 Potential effects, requirements for further survey, and mitigation are discussed below
for each of the identified potential constraints. Table 5 below, provides a summary of
the discussion.
Himalayan balsam – Invasive species
4.1.3 Himalayan balsam is listed under schedule 9 of the Wildlife and Countryside Act 1981,
under this law it is illegal to plant or otherwise permit the growth of this species in the
wild, this also includes spreading it, either with or without intent. As this species is
SEVERN TRENT WATER LIMITED SALFORD PRIORS SECTION 101A, A5S/11519, WARWICKSHIRE PRELIMINARY ECOLOGICAL APPRAISAL
ST13509/001 OCTOBER 2015
Page 21
present along the Ban Brook and the Brook intersects the site at two locations, it may
cause a constraint to the development at these two locations.
4.1.4 It is recommended that a 5m stand-off should be placed around all areas of Himalayan
balsam to prevent the spread of this species. Additionally, should any tracks or wheels
enter an area of Himalayan balsam, a thorough wheel wash must be undertaken in
situ, in order to prevent the spread of seed pods off site.
4.1.5 Should this buffer be maintained, Himalayan balsam is no longer considered to be a
constraint to development.
Ban Brook, headwaters and tributaries LWS
4.1.6 The proximity of Ban Brook, headwaters and tributaries LWS to the proposed
development site suggests there may be adverse impacts on the LWS due to
disturbance from site works. A strategy should be developed to ensure minimal
impacts from silt and dust during construction works such as implementation of a
construction environmental management plan (CEMP).
4.1.7 If a strategy to prevent any impacts from construction is implemented, the presence
of Ban Brook, headwaters and tributaries LWS is unlikely to be a constraint to
development.
Semi-improved grassland
4.1.8 The areas of semi-improved grassland immediately adjacent to the site are at risk from
damage during site works. Locations for site compounds and site works should avoid
areas of semi-improved grassland wherever possible.
4.1.9 Where areas of semi-improved grassland are impacted by site works, it is
recommended that the grassland is replanted with species of similar or greater
ecological value upon completion of works to ensure no net loss in biodiversity value
of the site. Consequently loss of semi-improved grassland is unlikely to be a constraint
to development.
SEVERN TRENT WATER LIMITED SALFORD PRIORS SECTION 101A, A5S/11519, WARWICKSHIRE PRELIMINARY ECOLOGICAL APPRAISAL
ST13509/001 OCTOBER 2015
Page 22
Hedgerows - UKBAP
4.1.10 Hedgerows provide important foraging and/or commuting habitats for a variety of
protected species, and are afforded protection under the UKBAP and LBAP for
Warwickshire. Site works aim to avoid areas of hedgerow.
4.1.11 Where removal of sections of hedgerow are necessary to facilitate works, it is
recommended that the hedgerow is replanted upon completion of works with native
species in order to mitigate for the loss. Replacement of all hedgerow sections will
ensure that hedgerows are unlikely to be a constraint to development.
Amenity Grassland
4.1.12 Amenity grassland provides foraging habitat for a variety of protected species. Site
works should aim to avoid these areas. However, should any areas of amenity
grassland be removed or damaged during works, it is recommended that these areas
are reseeded to ensure no net loss in biodiversity value of the site. Consequently,
amenity grassland is unlikely to be a constraint to development.
Mixed semi-natural woodland - UKBAP
4.1.13 Mixed semi-natural woodland is a valuable resource that provides commuting,
foraging, nesting and hibernation habitat for an assemblage of protected species that
may be present in the area. Additionally, it is a UKBAP habitat.
4.1.14 It is recommended that a 3 metre buffer is maintained between the woodland edge
and site works to prevent any damage to tree roots that may adversely affect the
condition of the woodland. The 3 metre buffer should be demarcated by high visibility
tape or fencing to ensure no encroachment into the buffer by site vehicles.
4.1.15 Adherence to the 3 metre buffer will ensure no adverse impacts on the woodland.
Consequently the presence of areas of semi-natural woodland is unlikely to be a
constraint to development.
Introduced shrubs
4.1.16 Introduced shrubs are an LBAP habitat in Warwickshire and provide cover and foraging
habitat for various protected species. Site proposals should aim to avoid any areas of
introduced shrub, however if this cannot be accommodated, it is recommended that
SEVERN TRENT WATER LIMITED SALFORD PRIORS SECTION 101A, A5S/11519, WARWICKSHIRE PRELIMINARY ECOLOGICAL APPRAISAL
ST13509/001 OCTOBER 2015
Page 23
any introduced shrubs damaged or removed during site works of should be replaced
with a species of similar or equal ecological value.
4.1.17 Replacement of introduced shrubs will ensure that this habitat is unlikely to be a
constraint to development.
Dense scrub
4.1.18 Dense scrub provides valuable hibernation, foraging, commuting and nesting habitat
for an assemblage of protected species. Dense scrub is also a LBAP habitat for
Warwickshire. Where removal of dense scrub is necessary to facilitate works, the
scrub should be replanted upon completion of works in order to mitigate for the loss.
Replacement of all scrub will ensure that scrub is unlikely to be a constraint to
development.
Arable field margins - UKBAP
4.1.19 Arable field margins support an array of fauna and flora and provide valuable foraging,
resting and commuting habitat for an assemblage of protected species. Additionally,
they are afforded protection under the UKBAP and LBAP for Warwickshire. Areas of
arable field margin encroached upon by site works should be kept to a minimum. If
impacted areas are kept to a minimum, the habitat lost will only occupy a very small
percentage of arable field margin in relation to the neighbouring landscape, and thus
this loss of habitat is not considered to adversely affect the nature conservation value
of this habitat in the local area.
Ditches
4.1.20 The ditches that lie within the site are not a UKBAP habitat, however they are listed
under the ‘Roadside Verges’ HAP. Both wet and dry ditches can provide valuable
wildlife corridors and commuting habitat to an assemblage of protected species.
Ditches should be avoided where possible. Implementation of a CEMP would ensure
no impacts to the water quality of the ditch. Should ditches be impacted by the works,
a suitably qualified ecologist should check these areas in advance.
4.1.21 Implementation of a CEMP and/or or adherence to a stand off from the working area
will ensure no adverse impacts upon ditches as a result of works. Ditches are not likely
to be a constraint to development.

ST13509/001 OCTOBER 2015
Page 24
Scattered trees
4.1.22 Trees scattered throughout the site have varying levels of ecological value.
Additionally, scattered trees are a LBAP habitat for Warwickshire. Site proposals
should aim to avoid tree removal where possible, however where this cannot be
accommodated, trees equal or greater in both number and ecological value should be
planted in areas near to where any trees are removed through site proposals.
4.1.23 Replacement of trees will ensure that trees are not considered to be a constraint to
development.
Watercourse
4.1.24 The watercourse intercepts the site at two separate points. Additionally watercourses
are both a UKBAP and LBAP habitat in Warwickshire. Site works aim to avoid the
watercourse and implementation of a CEMP will ensure that impacts are minimised.
Implementation of a CEMP will ensure that the watercourse is unlikely to be a
constraint to development.
Veteran trees
4.1.25 The veteran tree is located at grid reference: SP 06411 52005.
4.1.26 A veteran tree is classed as a tree that, by recognized 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. These
characteristics might typically include a large girth, signs of crown retrenchment and
hollowing of the stem.
4.1.27 The works should be designed to allow a suitable buffer around the tree to prevent
any damage to the tree or its roots. It is recommended that an arboricultural survey
including a tree protection is undertaken for the site prior to works.
Bats
4.1.28 The data search returned 16 records of bats within 2km of the search area. This
includes two records from within the site boundary, these are a common pipistrelle
on 23/04/2005 detected in a garden, and an unspecified bat roost in a loft adjacent to
the site boundary on 30/01/2013 (See Target Note 24 on Drawing ST13509-001).
SEVERN TRENT WATER LIMITED SALFORD PRIORS SECTION 101A, A5S/11519, WARWICKSHIRE PRELIMINARY ECOLOGICAL APPRAISAL
ST13509/001 OCTOBER 2015
Page 25
4.1.29 Though the buildings within and bordering the site may hold the potential to support
roosting bats, they are unlikely to be disturbed by site works as impacts will be highly
localised and thus the buildings will not be impacted by site works.
4.1.30 Additionally, site works aim to avoid any trees and areas of woodland, which may act
as a foraging and commuting corridor for bats and may also provide suitable roosting
habitat. A 3m buffer is recommended to be maintained from the woodland to prevent
any accidental damage caused by site works, which may lead to damage to a potential
bat roost. If this cannot be accommodated, any trees or buildings set to be removed
by site proposals should have their potential to support roosting bats assessed to
advise if any further survey effort is required.
4.1.31 If the 3 metre buffer is maintained, bats are no longer considered to be a constraint
to development and no further survey effort will be required.
Badger
4.1.32 There are records of badger sett within 2km of the site boundary. The nearest record
lies approximately 250m east of the site boundary.
4.1.33 Areas of habitat suitable to support badger setts are present within the site and may
be impacted by site proposals. Although no active badger setts were found, evidence
of badger using the site was found in the form of mammal corridors and a latrine.
4.1.34 It is recommended that a pre-construction badger sett check should be undertaken
for the site and up to 30 metres from the site boundary in all areas except where works
will occur entirely within hard standing. This will allow protection of any potential
badger setts in the area. Should a sett be found, a 30 metre stand off will be required
from the sett and all works. Where this cannot be accommodated, a licence would be
required from Natural England for disturbance of the sett.
Otter and water vole
4.1.35 The data search returned 10 records of otter within 2km and 1 historic record of water
vole. The otter records are from within the River Arrow which is separated from the
site by the A46, which acts as a physical barrier against dispersal of less mobile species
towards the site.
SEVERN TRENT WATER LIMITED SALFORD PRIORS SECTION 101A, A5S/11519, WARWICKSHIRE PRELIMINARY ECOLOGICAL APPRAISAL
ST13509/001 OCTOBER 2015
Page 26
4.1.36 Ban Brook was surveyed in 2005 to identify any otter or water vole activity in Ban
Brook near to the site. The survey found no evidence to suggest the presence of otter
or water vole present in the area. It is recommended that a pre-construction check
should be undertaken immediately prior to the commencement of works by a suitably
qualified ecologist to check for the presence of any water vole or otter activity. Should
any water vole burrows be found, a 5m buffer should be maintained to prevent
damage to the burrows from site works and prevent disturbance to water vole that
may be present within them. There are no potential otter holt locations along Ban
Brook at the proposed works locations. However there is the potential for otter to use
the Brook as a commuting route. Should evidence of otter be found during the pre-
construction check, it is recommended that a mitigation scheme for avoidance of
impacts on otter be developed and including within the CEMP.
Reptiles
4.1.37 There are two records of grass snake from within the 2km search area of the site
boundary. One of the records is historic located 1800m east of the site boundary, and
the other recorded was from 1300m west of the site, however this was provided
without a date.
4.1.38 Areas of habitat suitable to support reptiles are present within the site may be
disturbed through site works. In order to prevent any injury or mortality to any reptile
species, it is recommended that any suitable reptile habitat to be disturbed or
removed through site proposals should be hand searched by a suitably qualified
ecologist immediately prior to its removal. This will ensure protection of reptiles
throughout works. If reptiles are found, they will be moved to an area of suitable
habitat a sufficient distance away from the working area. Consequently, reptiles are
not a constraint to the development.
GCN
4.1.39 The data search provided one record of two juvenile GCN under a paving slab 1800m
east of the site boundary on 11/04/2004.
4.1.40 There were six potentially suitable waterbodies within 500m of the site boundary,
three of which were found to have potential to support breeding GCN (HSI results at
Appendix 4).
SEVERN TRENT WATER LIMITED SALFORD PRIORS SECTION 101A, A5S/11519, WARWICKSHIRE PRELIMINARY ECOLOGICAL APPRAISAL
ST13509/001 OCTOBER 2015
Page 27
4.1.41 It is considered highly unlikely that great crested newts are found within either of the
proposed compound areas, which are the only areas of land away from the existing
roads which are proposed to be affected by the development. The proposed
compound at Tothall Lane in the north of the site is over 500m away from any suitable
breeding ponds and significant barriers to movement in the form of roads and large
arable fields exist between these waterbodies and the site.
4.1.42 Similarly the proposed compound in the south of the site is located on regularly
disturbed land and separated from the closest ponds, which score poorly under the
HSI assessment, by extensive arable land.
4.1.43 For these reasons it is not considered that great crested newt surveys are required,
and that reasonable avoidance measures can be implemented. Reasonable avoidance
measures would comprise strimming of vegetation to encourage dispersal of animals
from the proposed construction area and careful removal of possible refuge sites
under ecological supervision.
Nesting birds
4.1.44 The ecological data search provided numerous records of notable bird species nesting
in the area.
4.1.45 Habitat to support potential nesting birds is present within the site in the form of
arable field margins, hedgerows, trees, dense scrub and buildings. It is recommended
that any works that will impact these habitats are undertaken outside of the usual bird
breeding season (normally taken to be March – August inclusive). If such timescales
cannot be accommodated, it is recommended that a check for the presence of active
nests, and nesting birds should be undertaken by a suitably qualified ecologist
immediately prior to the commencement of works. Any active nests should be
identified and protected subject to the relevant legal provisions until the nesting
attempt is complete. Protection is usually in the form of a 5 metre buffer from an
active nest.
4.1.46 Additionally, an owl box was noted in the area of mixed woodland at approximate
NGR: SP 05845 52023 (See Target Note 25 on Drawing ST13509-001). This is located
immediately adjacent to the planned location of the southern pumping station. It is

5.2.1 The majority of the site where works will take place holds limited ecological value as
it is primarily hard standing.
5.2.2 There are opportunities for enhancement throughout the site. It is recommended that
habitats disturbed or lost by proposals are enhanced through planting species of
greater ecological value and of local provenance. This would provide a significant
improvement to the current ecological value of the site.
5.2.3 The improvement of any species poor/defunct hedgerows to species rich/intact
hedgerows by planting woody species of local provenance would also provide a
considerable ecological enhancement.
5.3 Species
5.3.1 Installation of bat and bird boxes would provide suitable nesting and roosting habitats
for several species.

Legislation and Policy Summary
Appendix 1 – Legislation and Policy Summary
Legislation for Habitats/Sites
Designated Site/Habitat Status
Ramsar Sites Ramsar Sites are wetlands of international importance
designated following The Ramsar Convention. RAMSAR sites
have the same level of protection as SSSIs under the Wildlife and
Countryside Act 1981 (as amended).
SPA (Special Protection Areas) SPAs are classified in accordance with Article 4 of the EC
Directive on the Conservation of Wild Birds (79/409/EEC), the
Birds Directive. They are they seek to protect the habitats of rare
and vulnerable birds, listed in Annex I of the Birds Directive, and
for regularly occurring migratory species. The Wildlife and
Countryside Act 1981 (as amended) and the Conservation of
Habitats and Species Regulations 2010 implement the Birds
Directive in the UK.
SAC (Special Areas for Conservation) SACs are strictly protected areas which represent typical
European Union of habitats and (non-bird) species listed in
Annexes I and II of the EC Habitats Directive. The Wildlife and
Countryside Act 1981 (as amended) and the Conservation of
Habitats and Species Regulations 2010 implement the Habitats
Directive in the UK.
SSSI (Sites of Special Scientific Interest) SSSIs protect the best examples of the UK's flora, fauna, or
geological or physiographical features. Originally notified under
the National Parks and Access to the Countryside Act 1949, SSSIs
were renotified under the Wildlife and Countryside Act 1981 (as
amended). Modified provisions for the protection and
management of SSSIs were introduced by the Countryside and
Rights of Way Act 2000.
NNR (National Nature Reserves) NNRs are examples of some of the most important natural and
semi-natural terrestrial and coastal ecosystems in Great Britain.
NNRs are declared by the statutory country conservation
agencies under the National Parks and Access to the Countryside
Act 1949 and the Wildlife and Countryside Act 1981 (as
amended). Legal protection of NNRs is provided under The
Wildlife and Countryside Act 1981 (as amended).
Hedgerows All hedgerows are protected by the Hedgerows Regulations
1997, under which it is an offence to remove or destroy certain
Designated Site/Habitat Status
hedgerows without planning consent or permission from the
Local Planning Authority. These regulations do not apply to any
hedgerow within the curtilage of, or marking the boundary of
the curtilage of, a dwelling house.
LNR (Local Nature Reserves) Designated by the National Parks and Access to the Countryside
Act 1949, LNRs may be declared for nature conservation by local
authorities after consultation with the relevant statutory nature
conservation agency. Legal protection of LNRs is provided under
The Wildlife and Countryside Act 1981 (as amended).

the Wildlife & Countryside Act prohibits the release of any
animal species that are:
“not ordinarily resident in and is not a regular visitor to
Great Britain in a wild state”
Policy Summary
Section 40 of the Natural Environment and Rural Communities (NERC) Act imposes a legal
duty on Planning Authorities to ‘have regard’ to the conservation of biodiversity when
considering planning applications.
Section 41 of the NERC Act requires the Secretary of State to publish a list of species and
habitats of principal importance for conserving biodiversity in the UK. Such Biodiversity Action
Plan (BAP) Habitats and Species (2007) do not offer the species any specific protection but
help to highlight the species importance at a national level. This list is used by Local Planning
Authorities to identify the species and habitats that should be afforded priority when applying
the requirements of the National Planning Policy Framework (NPPF).
The NPPF underpins the Government’s planning policies for England and how these are to be
applied. The central theme of the NPPF is a presumption in favour of sustainable
development. This presumption does not apply where development requiring Appropriate
Assessment under the Birds or Habitats Directives is being considered, planned or
determined.
The NPPF states:
‘When determining planning applications, local planning authorities should aim to
conserve and enhance biodiversity by applying the following principles:
• if significant harm 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;
• proposed development on land within or outside a Site of Special Scientific
Interest (SSSI) likely to have an adverse effect on a SSSI (either individually or in
combination with other developments) should not normally be permitted.
Where an adverse effect on the site’s notified special interest features is likely,
an exception should only be made where the benefits of the development, at
this site, clearly outweigh both the impacts that it is likely to have on the
features of the site that make it of special scientific interest and any broader
impacts on the national network of SSSIs;
• development proposals where the primary objective is to conserve or enhance
biodiversity should be permitted;
• opportunities to incorporate biodiversity in and around developments should
be encouraged;
• planning permission should be refused for development resulting in the loss or
deterioration of irreplaceable habitats, including ancient woodland and the
loss of aged or veteran trees found outside ancient woodland, unless the need
for, and benefits of, the development in that location clearly outweigh the loss;
and
• the following wildlife sites should be given the same protection as European
sites: potential Special Protection Areas (SPA) and possible Special Areas of
Conservation (SAC); listed or proposed Ramsar sites; and sites identified, or
required, as compensatory measures for adverse effects on European sites,
potential SPAs, possible SACs, and listed or proposed Ramsar sites.’
The NPPF requires the Planning Authority to have a responsibility to promote the
preservation, restoration and re-creation of priority habitats, ecological networks and the
protection and recovery of priority species populations, linked to national and local targets,
and identify suitable indicators for monitoring biodiversity in the plan. In addition, the
planning system should contribute to and enhance the natural and local environment by
minimising impacts on biodiversity and providing net gains in biodiversity where possible,
contributing to the Government’s commitment to halt the overall decline in biodiversity,
including by establishing coherent ecological networks that are more resilient to current and
future pressures.
The National Planning Policy Guidelines (NPPG) provides information on the implementation
of the policies set out within the NPPF and how these policies are associated with supporting
legislation, policies and supplementary guidelines.
With regard to Schedule 1 and 2 projects, the NPPG explains the requirements of Town and
Country Planning (EIA) Regulations 2011, including the legislation, stages and implementation
of the act.
In terms of planning applications which fall outwith the EIA regulations the NPPG provides the
following broad guidelines (extracts below):
Section 40 of the Natural Environment and Rural Communities Act 2006, places a duty
on all public authorities in England and Wales to have regard, in the exercise of their
functions, to the purpose of conserving biodiversity. A key purpose of this duty is to
embed consideration of biodiversity as an integral part of policy and decision making
throughout the public sector, which should be seeking to make a significant
contribution to the achievement of the commitments made by Government in its
Biodiversity 2020 strategy.
Guidance on statutory obligations concerning designated sites and protected species
is published separately …. Local planning authorities should take a pragmatic approach
– the aim should be to fulfil statutory obligations in a way that minimises delays and
burdens.
The National Planning Policy Framework is clear that pursuing sustainable
development includes moving from a net loss of biodiversity to achieving net gains for
nature, and that a core principle for planning is that it should contribute to conserving
and enhancing the natural environment and reducing pollution.
