4 1. INTRODUCTION 1.1. Background & Proposals was commissioned in by Pegasus Group, to undertake an of Camel Creek, Trevibban Farm, Cornwall (see Plan ECO1) The proposals for the site are for a resort comprising up to 241 dwellings, with a swimming pool, a lake system, associated open space and landscaping (see Appendix 1) Site Characteristics The Application Site, (hereafter referred to as the site ) is located at Trevibban Farm, Cornwall. The site is bordered to the west and southwest by agricultural fields and open countryside, to the north by residential properties, a vineyard and agricultural fields, and to the east by a wooded stream, with Cornwall s Crealy Great Adventure Park and agricultural fields beyond. To the southeast of the site lies an area of heathland that is designated as the Trelow Downs Site of Special Scientific Interest (SSSI) The vast majority of the site itself comprises semi-improved grassland with areas of rush-dominated grassland. The fields are separated by hedgerows and trees, as well as fences and scrub, and there are grass tracks also present through the site. Five buildings are present within the site, with associated areas of hardstanding and amenity grassland and planting. Areas of woodland are present along the eastern and southeastern borders of the site and small areas of scrub are also present, generally associated with the boundary features and wet issues that flow through the site into the stream bordering the eastern and southeastern boundary This document assesses the ecological interest of the site at Camel Creek, Trevibban Farm, Cornwall. The importance of the habitats within the site is evaluated with due consideration given to the current guidance published by the Chartered Institute of Ecology and Environmental Management (CIEEM) Where necessary mitigation measures are recommended so as to safeguard any significant existing ecological interest within the site. Specific enhancement opportunities that are available for habitats and wildlife within the site are detailed where appropriate, with reference to the 'UK Post-2010 Biodiversity Framework' 2. Finally conclusions are drawn. 1 Institute of Ecology and Environmental Management (2006) Guidelines for Ecological Impact Assessment in the United Kingdom (version 7 July 2006). 2 JNCC and Defra (on behalf of the Four Countries' Biodiversity Group) (2012) UK Post-2010 Biodiversity Framework.

5 2. SURVEY METHODOLOGY 2.1. The methodology utilised for the survey work can be split into three areas, namely desk study, habitat survey and faunal survey. These are discussed in more detail below Desk Study In order to compile background information on the site and the surrounding area, contacted the Environmental Records Centre for Cornwall and The Isles of Scilly (ERCCIS) Further information on designated sites from a wider search area was obtained from the online Multi-Agency Geographic Information for the Countryside (MAGIC) 3 database. This information is reproduced at Appendix 2 and where appropriate on Plan ECO Habitat Survey Methodology Habitat surveys were carried out in mid- in order to ascertain the general ecological value of the site and to identify the main habitats and associated plant species The site was surveyed based around extended Phase 1 survey methodology 4, as recommended by Natural England, whereby the habitat types present are identified and mapped, together with an assessment of the species composition of each habitat. This technique provides an inventory of the basic habitat types present and allows identification of areas of greater potential which require further survey. Any such areas identified can then be examined in more detail Using the above method, the site was classified into areas of similar botanical community types, with a representative species list compiled for each habitat identified All the species that occur in each habitat would not necessarily be detectable during survey work carried out at any given time of the year, since different species are apparent at different seasons. Although the surveys were undertaken outside the optimum period for Phase 1 habitat and botanical surveys, given the location of the site in the southwest of Cornwall and the habitats present (dominated by semi-improved grassland separated by hedgerows), it is considered that a robust botanical assessment has been made Faunal Survey Obvious faunal activity, such as birds or mammals observed visually or by call during the course of the surveys, was recorded. Specific attention was paid to any potential use of the site by protected species, Priority Species, or other notable species Joint Nature Conservation Committee (2010).

6 In addition to general observations of faunal activity, specific surveys were undertaken in for bats and Badgers Meles meles Experienced ecologists undertook the faunal surveys with regard to established best practice and guidance issued by Natural England. Details of the methodologies employed are given below. Bats Field surveys were undertaken within the site with regard to best practice guidelines issued by, the Joint Nature Conservation Committee ( ) and the Bat Conservation Trust ( ) The buildings within the site were assessed for their potential to support roosting bats in. In addition, during these surveys the buildings were subject to internal and external surveys using ladders, torches, mirrors, binoculars and an endoscope where necessary Evidence of the presence of bats was searched for, with particular attention paid to the roof areas and gaps between rafters and beams. Specific searches were made for bat droppings, which can indicate present or past use and extent of use and other signs to indicate the possible presence of bats e.g. presence of stained areas, or areas that are conspicuously cobweb-free In addition, all trees within the site were assessed for their potential to support roosting bats. Features typically favoured by bats were searched for, including: Obvious holes, e.g. rot holes and old Woodpecker holes; Dark staining on the tree, below the hole; Tiny scratch marks around a hole from bat claws; Cavities, splits and or loose bark from broken or fallen branches, lightning strikes etc; and Very dense covering of mature Ivy over trunk. Badgers Specific surveys for Badgers were carried out in The surveys comprised two main elements. Firstly, searching thoroughly for evidence of Badger setts. For any setts that were encountered standard survey practice would record the location of each sett entrance, even if the entrance appeared disused. The following specific information was recorded where appropriate: i) The number and location of well used or very active entrances; these are clear of any debris or vegetation and are obviously in regular use and may, or may not, have been excavated recently. 5 Mitchell-Jones, A.J. & McLeish, A.P. (Eds.) (2004). Bat Workers Manual. 3 rd edition. Joint Nature Conservation Committee, Peterborough. 6 Bat Conservation Trust (2012). Bat Surveys Good Practice Guidelines (2 nd Edition). Bat Conservation Trust, London. 3

7 ii) iii) The number and location of inactive entrances; these are not in regular use and have debris such as leaves and twigs in the entrance, or have plants growing in or around the edge of the entrance. The number of disused entrances; these have not been in use for some time, are partly or completely blocked and cannot be used without considerable clearance. If the entrance has been disused for some time all that may be visible is a depression in the ground where the hole used to be together with the remains of the spoil heap Secondly, any evidence of Badger activity such as well-worn paths, runthroughs, snagged hair, footprints, latrines and foraging signs was recorded so as to build up a picture of the use of the site by this species. 4

14 4. WILDLIFE USE OF THE SITE 4.1. General observations were made during the surveys of any faunal use of the site, with specific attention paid to the potential presence of protected species. Specific surveys were undertaken with regard to bats and Badgers. Bats Tree Surveys 4.2. A number of trees within woodland W1 are likely to have developed features suitable to support roosting bats. However, the woodland is to be retained within the development proposals in any event. No other trees within the site were recorded as having developed features suitable to support roosting bats. Internal / External Surveys 4.3. It is considered that buildings B1-B4 do not have any potential to support roosting bats due to their design and construction Building B5 has low potential to support roosting bats, and this building is to be retained within the development proposals in any event. Habitats 4.5. It is considered that the hedgerows, trees and woodland within the site offer suitable foraging and navigational opportunities for bats Background Records. The ERCCIS returned no records of any bats from within the site itself. A single record of dead Pipistrelle Pipistrellus pipistrellus was returned from the gird square east of the site in Badgers 4.7. Four Badger setts were recorded during the surveys undertaken. These were situated along the southern boundary of the site (the location of these can be seen on Plan ECO3). Each sett is described below. Sett One 4.8. Sett one is located at the southern boundary of field F7, and the northern boundary of the adjoining woodland W1. This is a main set comprising 16 active entrances were recorded, together with old bedding in some entrances. Pathways were recorded along the southern boundary of field F7 and through the adjacent woodland and snuffle pits were recorded within field F7. Pushthroughs were recorded through the fence line between field F7 and woodland W1. Sett Two 4.9. Sett two is located at the southern margin of field F7. Two active entrances and one collapsed entrance were recorded, together with associated mammal paths / push-throughs between field F7 and woodland W1. It is considered likely that sett two is a subsidiary sett to sett one. 11

15 Sett Three Sett three is a potential Badger sett located at the southern margin of field F7. One clear entrance was recorded, although no evidence of Badger, such as hairs, was recorded. It is considered likely that sett three is a potential outlier sett to sett one. Sett Four Sett four is located at the southern margin of field F8. One active entrance was recorded. It is considered likely that sett four is a subsidiary sett to sett one Background Records. The ERCCIS returned no records of any Badgers from within the site itself. The nearest record of Badger was returned 0.5km southwest of the site in A low resolution record of an active Badger sett was also returned from the wider study area in Other Mammals It is considered that the scrub, hedgerows and woodlands within the site provide suitable habitat for Dormouse. However, a nut search was conducted and no evidence of this species was recorded It is considered that stream S1 and the wet issues within the site provide suitable foraging and dispersal opportunities for Otter Lutra lutra It is considered that stream S1 offers some limited opportunities for Water Vole Arvicola amphibious. It is not considered that the wet issues within the site offer any suitable opportunities for Water Vole Evidence of Rabbits Lepus curpaeums was recorded associated with the hedgerows, and as stated above the site is grazed by farmed Red Deer. No evidence of any other mammals was recorded within the site. However, it is considered that the habitats within the site provide suitable opportunities for a range of common mammal species Background Records. The ERCCIS returned no records of any other notable mammals were returned from within the site itself. The nearest record of Dormouse was returned from approximately 1km west of the site in No records of any other mammals were returned. Birds General observations of the use of the site by birds were made during March The Red List and Priority Species House Sparrow was recorded associated with the residential properties in the north of the site, while the Priority Species Dunnock were recorded associated with the hedgerows and woodland within the site A number of common bird species were also recorded within the site, including Blue Tit Cyanistes caeruleus, Blackbird Turdus merula, Magpie Pica pica, Wren Troglodytes troglodytes, Woodpigeon Columba palumbus, Jackdaw 12

16 Corvus monedula, Robin Erithacus rubecula, Raven Corvus corax, Buzzard Buteo buteo, Chiffchaff Phylloscopus collybita, Long-tailed Tit Aegithalos caudatus, Snipe Gallinago gallinago, Meadow Pipit Anthus pratensis, Redlegged Partridge Alectoris rufa, Pheasant Phasianus colchicus and Chaffinch Fringilla coelebs In addition, Guinea Fowl Numida meleagris were recorded within field F1 and in the amenity grassland surrounding building B A Barn Owl Tyto alba box is present within building B1. Around 20 Barn Owl pellets were noted within building B1, the vast majority of which were recorded as being old. Indeed, anecdotal information suggests this box has been occupied by Barn Owls in previous years, but not during the 2014 nesting season It is considered that the scrub, hedgerows, trees and woodland within the site offer suitable nesting and foraging opportunities for birds, while the rushdominated grassland offers some suitable nesting opportunities for groundnesting birds such as Snipe. It is also considered that the semi-improved grassland and scrub-dominated grassland offer some suitable foraging opportunities for birds Background Records. The ERCCIS returned no records of any notable birds from within the site itself. A number of records for birds were returned from the 1km square east of the site in 2006, including the Red List species Sky Lark Arlauda arvensis the Red List and Priority species Grasshopper Warbler Locustella naevia, Cuckoo Cuculus canorus, and Herring Gull Larus argentatus. Reptiles It is considered that the margins of the grass tracks, the scrub-dominated grassland and the woodland margins offer suitable opportunities for reptiles, while the rush-dominated grassland offers some suitable habitat for e.g. Grass Snake Natrix natrix. However, it is considered that the vast majority of the grazed semi-improved grassland does not provide suitable opportunities for reptiles Background Records. The ERCCIS returned no records of any reptiles from within the site itself. The nearest records of Slow Worm Anguis fragilis and Grass Snake were returned from approximately 1.4km southwest of the site in Great Crested Newts There are no ponds within the site. Three ponds are present within 500m of the site boundary. However, the majority of these ponds are separated from the habitats within the site by the fast flowing stream that runs through the woodland and which is considered to act as a dispersal barrier to Great Crested Newts. In addition, these ponds are further considered to be unsuitable for Great Crested Newts as they are stocked with fish. In any event, the site lies within in an area identified within the Habitat Suitability Index assessment as being unsuitable for Great Crested Newts. 13

17 4.29. Background Records. No records of Great Crested Newts were returned from within the site or wider study area On the basis of the above, and given the absence of this species form the local area, it is considered that the habitats present within the site do not offer suitable terrestrial habitat for Great Crested Newts and as such, no further consideration is given to this species within this report. Invertebrates Given the habitats present it is likely an assemblage of common invertebrate species would be present within the site. However, it is not considered that any of these invertebrate species would be reliant on the habitats present within site Background Records. The ERCCIS returned no records of any notable invertebrates from within the site itself. The nearest records of the Priority Species Wall Lasiommata megera was returned from the same grid square as the site in It is not considered that any of the habitats present within the site offer any suitable opportunities for Wall. 14

18 5. ECOLOGICAL EVALUATION 5.1. The Principles of Ecological Evaluation The latest guidelines for ecological evaluation produced by CIEEM 7 propose an approach that involves professional judgement, but makes use of available guidance and information, such as the distribution and status of the species or features within the locality of the project The methods and standards for site evaluation within the British Isles have remained those defined by Ratcliffe 8. These are broadly used across the United Kingdom to rank sites so priorities for nature conservation can be attained. For example, current sites of Special Scientific Interest (SSSI) designation maintains a system of data analysis that is roughly tested against Ratcliffe s criteria In general terms, these criteria are size, diversity, naturalness, rarity and fragility, while additional secondary criteria of typicalness, potential value, intrinsic appeal, recorded history and the position within the ecological / geographical units are also incorporated into the ranking procedure Any assessment should not judge sites in isolation from others, since several habitats may combine to make it worthy of importance to nature conservation Further, relying on the national criteria would undoubtedly distort the local variation in assessment and therefore additional factors need to be taken into account, e.g. a woodland type with comparatively poor species diversity, common in the south of England, may be of importance at its northern limits, say in the border country In addition, habitats of local importance are often highlighted within a local Biodiversity Action Plan (BAP). Cornwall s Biodiversity Action Plan 9 currently contains a number of BAP habitats and species Levels of importance can be determined within a defined geographical context from the immediate site or locality through to the International level The legislative and planning policy context are also important considerations and have been given due regard throughout this assessment Habitat Evaluation Designated Sites Statutory Sites: There are no statutory designated sites present within the site itself. However, the Trelow Downs SSSI lies adjacent to the site 7 Institute of Ecology and Environmental Management (2006). Guidelines for Ecological Impact Assessment in the United Kingdom (version 7 July 2006). 8 Ratcliffe, D A (1977).

19 along its south-eastern boundary, and is separated by woodland W1 and a stream, and lies on the opposite side of a valley to the site. This SSSI is designated for its heathland, valley mire communities and scrub It is not considered that the development proposals would have any adverse effects on this SSSI from contaminated run-off, given that it lies on the opposite side of a valley. However, standard engineering practice in respect of pollution control, as part of the development proposals will negate any potential effect to the stream, which borders the souteastern edge of the site and the northern edge of the SSSI. In addition, any potential detrimental effects from dust contamination will be mitigated for through standard industry best practice measures. As such, given the above, it is not considered that there will be any direct or indirect adverse effects on this statutory designated site as a result of the development proposals Non-statutory Sites: There are no non-statutory designated sites within or immediately adjacent to the site. The nearest County Wildlife Site (CWS) is Trevillador CWS that lies approximately 260m northeast of the site. This CWS is designated for its mixed broad-leaved woodland and for the possible presence of Priority Habitat upland mixed ashwoods, and for the presence of the Priority Species and European Protected Species Otter. This CWS is separated from the site by roads, tracks and arable fields. This CWS is connected to the site by the stream. However, as set out above, standard engineering practices in respect of pollution control as part of the development proposals will negate any potential effect to the stream. As such, it is not considered that there will be any direct or indirect adverse effects on this non-statutory designated site as a result of the development proposals. Habitats Semi-improved Grassland and Grass Tracks The semi-improved grassland and grass tracks within the site are of limited ecological value in terms of species content, comprising only common and widespread species. However, it is considered that this habitat offers suitable foraging opportunities for Badgers and birds Areas of this habitat are to be lost to the development proposals Mitigation and Enhancements. Losses to this habitat could be mitigated for through the oversowing of the retained grassland areas (such as the areas of open space) with a species-rich wildflower grassland seed mixture (such as Emorsgate s Standard General Purpose Meadow Mixture EM2) and implementation of a suitable management regime, to increase the floristic diversity of the site accordingly. In addition, the provision of green roofs within the development proposals will diversify the habitats present. It is recommended that the green roofs be sown with a native wildflower seed mixture (such as Emorsgate s Wild Flowers for Green Roofs Mixture ER1F, or Emorsgate s Turf Roof Mixture ER1). 16

20 Rush-dominated Grassland The rush-dominated grassland within the site is of limited ecological value, comprising only common and widespread species. However, it is considered that this habitat offers suitable nesting opportunities for some ground-nesting birds and foraging opportunities for a range of birds The majority of this habitat is to be lost within the development proposals Mitigation and Enhancements. It is recommended that the new lake system be planted with a diverse range of native aquatic and marginal vegetation of known wildlife value, while any ephemerally wet areas be sown with a native wildflower grassland seed mixture suitable for wet / damp conditions (such as Emorsgate s Meadow Mixture for Wetlands EM8) which will increase the floristic diversity of the site. The creation of the new lake system within the site would serve to diversify the habitats within the site, provide new opportunities for a range of wildlife not currently present within the site, and increase the biodiversity of the site accordingly. Scrub-dominated Grassland The scrub-dominated grassland is of limited ecological value in terms of its species content, comprising only common and widespread species. However, it is considered that this habitat offers suitable foraging opportunities for birds and Badgers, and potentially suitable habitat for reptiles The scrub-dominated grassland is to be lost within the development proposals Mitigation and Enhancements. Losses to this habitat could be offset and enhancements realised through the oversowing of the retained grassland areas (such as the areas of open space) with a species-rich wildflower grassland seed mixture (such as Emorsgate s Standard General Purpose Meadow Mixture EM2) and implementation of a suitable management regime, to increase the floristic diversity of the site accordingly The development proposals include new areas of buffer planting and it is recommended that these be planted with a diverse mix of native species, which will provide new and enhanced opportunities for wildlife. Scrub The scrub within the site is of limited ecological value in terms of its species content, comprising only common and widespread species. However, it is considered that this habitat offers suitable foraging opportunities for Badgers and foraging and nesting opportunities for birds The scrub is to be lost within the development proposals Mitigation and Enhancements. It is considered that no specific mitigation measures would be necessary for the loss of this habitat. However, the development proposals include new areas of buffer planting and it is 17

21 recommended that these be planted with a diverse mix of native species, which will provide new and enhanced opportunities for wildlife. Woodland The woodland at the margins of the site is of relatively greater ecological value in the context of the site. It is considered that the woodland within the site provides suitable foraging and navigational opportunities for bats, nesting and foraging opportunities for birds, as well as shelter and foraging opportunities for Badgers The woodland is to be retained and safeguarded within the development proposals Mitigation and enhancements. It is recommended that the footprint of any buildings be situated outside the root protection zones of the trees within the woodland. Indeed, the woodland, together with all retained semi-mature / mature trees within the site will be fenced at canopy width according to the current British Standard (BS 5837:2012) before landscaping work commences on site, to protect roots from compaction A significant numbers of trees are to be planted as part of the development proposals, and it is recommended that the new tree planting be based around native species of local provenance Any potentially detrimental effects of dust contamination on the retained woodland through dust contamination will be mitigated through standard industry best practice measures. In any event, the residual effect of the construction of the proposed development will be short term, with construction dust infrequently affecting sensitive receptors. Hedgerows and Trees The hedgerows and trees within the site are also of greater ecological value in the context of the site. A number of hedgerows within the site are considered to be species-rich, with three considered to potentially qualify as important under The Hedgerows Regulations The hedgerows and trees within the site also offer suitable navigational and foraging opportunities for bats, foraging and nesting opportunities for birds and foraging opportunities for Badgers Under the development proposals, hedgerows H9, H12, H14 and H15 will be lost, of which hedgerows H9 and H14 are species-rich and hedgerow H15 potentially qualifies as important under The Hedgerow Regulations Partial losses would occur to hedgerows H5, H7 and H16 of which hedgerows H5 and H7 are species-rich The majority of the trees are to be retained and safeguarded within the development proposals, although some losses to trees would occur to accommodate the development proposals Mitigation and Enhancements. Where losses to hedgerows are to occur, new hedgerow / tree planting should be undertaken of a length / area greater than that lost, to offset these losses. Indeed, the development 18

22 proposals include the planting of a large number of native trees, which would more than offset loses to any hedgerows Any losses to the trees would be more than mitigated for through the planting of the large number of new native trees as part of the development proposals It is recommended that any additional planting as part of the landscape proposals, should utilise a diverse mix of native species, or species of benefit to wildlife wherever possible. Amenity Grassland and Planting The amenity grassland and planting within the site is of limited ecological value, comprising a number of non-native species The amenity grassland and planting within the site is to be retained within the development proposals Mitigation and enhancements. No mitigation is required. Buildings and Hardstanding The buildings and hardstanding within the site are of negligible ecological significance. However, building B1 does provide suitable nesting opportunities for Barn Owl Buildings B1-B4 are to be lost to the development proposals Mitigation and Enhancements. No specific mitigation is required. Wet Issues The wet issues within the site are of limited ecological value. However it is considered that the wet issues within the site offer suitable foraging and dispersal opportunities for Otter The wet issues within the site are to be lost to the development proposals Mitigation and Enhancements. Losses to this habitat could be compensated for and enhancements realised through the creation of the new lake complex. It is recommended that the new lake system be planted with a diverse range of native aquatic and marginal vegetation of known wildlife value, while any ephemerally wet areas be sown with a native wildflower grassland seed mixture suitable for wet / damp conditions (such as Emorsgate s Meadow Mixture for Wetlands EM8) which will increase the floristic diversity of the site. The creation of the new lake system within the site would serve to diversify the habitats within the site, provide new opportunities for a range of wildlife not currently present within the site, and increase the biodiversity of the site accordingly. 19

23 Stream Stream S1 is of some ecological value. It is considered that stream S1 provides suitable opportunities for Otter for foraging, dispersal and holts and offers limited burrowing and foraging opportunities for Water Vole The stream is to be retained within the development proposals Mitigation and Enhancements. Standard engineering practice in respect of pollution control, as part of the development proposals will negate any potential effect to the stream. In addition, any potential detrimental effects from dust contamination will be mitigated for through standard industry best practice measures. As such, given the above, it is not considered that there will be any adverse effect upon the stream as a consequence of the development proposals Faunal Evaluation Bats Legislation. All bats are protected under Schedule 5 of the Wildlife and Countryside Act 1981 (as amended) and included on Schedule 2 of the Conservation of Habitats and Species Regulations 2010 ( the Habitats Regulations ). These include provisions making it an offence to: Deliberately kill, injure or take (capture) bats; Deliberately disturb bats in such a way as to be likely to significantly affect:- (i) the ability of any significant group of bats to survive, breed or rear or nurture their young; or to hibernate; or (ii) to affect significantly the local distribution or abundance of the species concerned; Damage or destroy any breeding or resting place used by bats; Intentionally or recklessly obstruct access to any place used by bats for shelter or protection (even if bats are not in residence) The words deliberately and intentionally include actions where a court can infer that the defendant knew that the action taken would almost inevitably result in an offence, even if that was not the primary purpose of the act The offence of damaging (making it worse for the bat) or destroying a breeding site or resting place is an absolute offence. Such actions do not have to be deliberate for an offence to be committed In accordance with the Habitats Regulations the licensing authority (Natural England) must apply the three derogation tests as part of the process of considering a licence application. These tests are that: 1. the activity to be licensed must be for imperative reasons of overriding public interest or for public health and safety; 2. there must be no satisfactory alternative; and 3. the favourable conservation status of the species concerned must be maintained. 20

24 Licences can usually only be granted if the development is in receipt of full planning permission Site Usage. There are no trees within the site that have developed features suitable to support roosting bats None of the buildings to be lost to the development proposals offer suitable roosting opportunities for bats, given their design and construction It is considered that the hedgerows, trees and woodland within the site offer suitable foraging and navigational opportunities for bats Mitigation and Enhancements. Recommendations have already been made above to offset losses to hedgerows and trees through new native hedgerow / tree planting. The inclusion of new hedgerow planting and a significant number of new trees will more than offset losses to the hedgerows and trees and provide new and enhanced foraging and navigational opportunities for bats. The creation of wildflower grassland within the areas of retained grassland, the creation of new green roofs, and the creation of the new lake system (to be planted with native aquatic / marginal species), will provide further enhanced foraging opportunities for bats. As such, overall it is considered that foraging and navigational resources for bats would be greatly enhanced post-development Where necessary, a sympathetic lighting regime associated with the new proposals will be implemented to minimise light spillage into key areas, such as the woodland. To maintain suitable conditions for bats, it is recommended that the use of sodium or LED lights, which produce less light spillage than other types of lighting, and have no low / no UV content, or UV-filtered lights should be considered to reduce the light spillage on existing bat flight lines. In addition, the spillage of the light can be reduced further through use of low-level lights and the employment of lighting hoods which will direct light below the horizontal plane, preferably at an angle less than 70 degrees In addition it is recommended that bat boxes, such as Schwegler 1FF boxes (see Appendix 3 for suitable examples), are erected within the site on suitable existing trees and positioned out of reach of opportunistic predators such as cats. This model of bat box is known to be attractive to Pipistrelle, which are known from the local area. These measures will provide increased roosting opportunities across the site over the existing situation. Badgers Legislation. The Protection of Badgers Act 1992 consolidates the previous Badgers Acts of 1973 and The legislation aims to protect the species from persecution, rather than being a response to an unfavourable conservation status, as the species is in fact common over most of Britain, with particularly high populations in the southwest As well as protecting the animal itself, the 1992 Act also makes the intentional or reckless destruction, damage or obstruction of a Badger sett 21

25 an offence. A sett is defined as any structure or place which displays signs indicating current use by a Badger 10. Current use of a Badger sett is defined by Natural England as how long it takes the signs to disappear, or more precisely, to appear so old as to not indicate current use In addition, the intentional elimination of sufficient foraging area to support a known social group of Badgers may, in certain circumstances, be construed as an offence by constituting cruel ill treatment of a Badger Site Usage. A main sett, two subsidiary setts and an outlier sett, all of which are active, were recorded within field F7 and F8, together with a number of Badger latrines and footprints recorded throughout the site Mitigation and Enhancements. It is recommended that the footprint of any development be offset from the Badger setts by at least 30m. Should any of the outlier or subsidiary setts need to be closed / partially closed to accommodate the development proposals, a Natural England licence would be applied for During the construction phase of development it is often necessary to undertake a number of additional measures to safeguard any Badgers present on a site, particularly in regard to disturbance, loss of foraging and other related issues It is recommended that all contractors working in the vicinity of the Badger sett should be briefed regarding the presence of Badgers and of the types of activities that would not be permissible on site. Any licensing requirements should be particularly highlighted Any trenches or deep pits that are to be left open overnight should be provided with a means of escape should a Badger enter. This could simply be in the form of a roughened plank of wood placed in the trench as a ramp to the surface. This is particularly important if the trench fills with water Any trenches/pits should be inspected each morning to ensure no Badgers have become trapped overnight. Should a Badger get stuck in a trench it will likely attempt to dig itself into the side of the trench, by forming a temporary sett. Should a trapped Badger be encountered, Ecology Solutions should be contacted immediately for further advice The storage of topsoil or other soft building materials within the site should be given careful consideration. Badgers will readily adopt such mounds as setts, which would then be afforded the same protection as established setts. So as to avoid the adoption of any mounds, they should be subject to daily inspections (or nightly patrols if 24 hour security is present on site) or consideration given to fencing them with Badger proof fencing. 10 Protection of Badgers Act 1992 (as amended). Guidance on Current Use in the definition of a Badger Sett 22

26 During the development the storage of any chemicals required for the building construction should be well away from any Badger activity and contained in such a way that they cannot be accessed or knocked over by any roaming Badgers The retention of the woodland, hedgerows and trees, and the extensive planting of new native trees, as well as the creation of areas of new wildflower grassland, will maintain and enhance foraging opportunities for Badgers. It is recommended that any new planting as part of the landscape proposals include fruit-bearing species to provide new seasonal foraging opportunities for Badgers. Other Mammals Site Usage. Evidence of Rabbit was recorded associated with the hedgerows, and as stated above the farm is grazed by farmed Red Deer. It is considered that the scrub, hedgerows and woodland within the site offer suitable opportunities a range of small mammals, including Dormouse, although no evidence of this species was recorded It is considered that the wet issues within the site and the stream at the site boundary offer suitable opportunities for Otter, although no evidence of this species was recorded It is considered that the stream within the site offers limited opportunities for Water Vole, although no evidence of this species was recorded Mitigation and Enhancements. The majority of the hedgerows and trees within the site are to be retained within the development proposals. Any losses to the scrub and hedgerows will be more than compensated for with the new hedgerow planting, extensive planting of trees, creation of new areas of wildflower grassland and the creation of new areas of wet / marshy grassland. Should Dormouse be recorded within the site, a Natural England licence will likely be required before any hedgerow / scrub removal works can commence Any losses to the wet issues within the site will be more than compensated for with the creation of the new lake complex and standard engineering practices as described above will ensure that the stream is not adversely affected by the development proposals. Should Dormouse be recorded within the site, a Natural England licence will likely be required before any hedgerow / scrub removal works can commence. Birds Legislation. Section 1 of the Wildlife and Countryside Act 1981 (as amended) is concerned with the protection of wild birds, whilst Schedule 1 lists species that are protected by special penalties. All species of birds receive general protection whilst nesting Site Usage. The scrub, hedgerows, trees and woodland within the site offer suitable foraging and nesting opportunities for birds, while the semiimproved grassland offers suitable foraging opportunities for birds. A Barn 23

27 Owl box is present within building B1, together with evidence and anecdotal evidence of past usage by Owls Mitigation and Enhancements. The planting of new tree planting will provide new and enhanced foraging and nesting opportunities for birds, while the creation of new areas of wildflower grassland, the creation of new areas of wet grassland and the creation of a new lake will provide enhanced foraging opportunities for birds, as well as new foraging and nesting opportunities for aquatic bird species. As such, it is considered that opportunities for birds within the site will be greatly enhanced postdevelopment In order to compensate for the loss of the Barn Owl box within building B1, it is recommended that a new Barn owl box be provided within a suitable new building / tree to provide continued nesting opportunities for this species As a precautionary measure it is recommended that any required clearance of any suitable nesting vegetation (including tree felling) be undertaken outside the bird nesting season (March to July inclusive) to avoid any potential offence. Should the above timing constraints conflict with any timetabled works, it is recommended that works commence only after a suitably qualified ecologist has undertaken checks to ensure no nesting birds are present. If nesting birds are found to be present during checks then clearance would need to be delayed until young have fledged Simple enhancement measures could ensure the ornithological interest at the site is increased. The erection of bird nest boxes could provide further enhancements for this group if placed on suitable semi-mature / mature trees or buildings post-development. Using nest boxes of varying designs would maximise the species complement attracted to the site, and where possible these could be tailored to provide opportunities for red listed / Priority Species known from the local area, e.g. House Sparrow (see Appendix 4 for suitable examples). Reptiles The rough margins of the grass tracks and scrub-dominated grassland only limited suitable opportunities for reptiles Mitigation and Enhancements. As a precautionary measure it is recommended that, prior to any works within the grass tracks and scrubdominated grassland, a habitat manipulation exercise be carried out to encourage any reptiles that may be present to move away from those areas into areas of adjacent retained habitat The creation of new areas of species-rich wildflower grassland will provide new suitable habitat for reptiles over the existing situation, while the creation of new areas of species-rich wet grassland will also create potentially suitable habitat for e.g. Grass Snake, known from the local. 24

28 Invertebrates Site Usage. Given the habitats present it is likely an assemblage of common invertebrate species would be present within the site Mitigation and Enhancements. The implementation of other measures recommended above would also likely provide knock-on benefits for invertebrates, e.g. through new tree and hedgerow planting and use of species of wildlife benefit. The provision of nectar-rich flowers within the wildflower grassland and green roofs will also provide suitable foraging resources for a range of invertebrates, while the inclusion of species such as Lucerne and Clovers within the wildflower grassland seed mixture will provide new and enhanced opportunities for a number of invertebrates species. The creation of the lake system, to be planted with native aquatic and marginal plants, will diversify habitats present and provide new habitats for a range of aquatic invertebrate species It is recommended that log piles be incorporated into the new woodland areas, which would be beneficial to saproxylic species. 25

29 6. PLANNING POLICY CONTEXT 6.1. The planning policy framework that relates to nature conservation at Camel Creek, Trevibban Farm, Cornwall is issued at two main administrative levels: nationally through the National Planning Policy Framework and locally, through the emerging Cornwall Local Plan and saved policies from the North Cornwall Local Plan. The proposed development will be judged in relation to the policies contained within these documents National Policy National Planning Policy Framework The National Planning Policy Framework (NPPF) sets out the Government s requirements for the planning system and was adopted on 27th March It replaces previous national planning policy, including PPS9 (Biodiversity and Geological Conservation) published in The key element of the NPPF is that there should be a presumption in favour of sustainable development, which should be seen as a golden thread running through both plan-making and decision-taking (paragraph 14). It is important to note that this presumption does not apply where development requiring Appropriate Assessment under the Birds or Habitats Directives is being considered, planned or determined (paragraph 119), although this is not applicable to the proposals in this case A number of policies in the NPPF are comparable to those in Planning Policy Statement (PPS)9 (which it replaced), including reference to minimisation of impacts to biodiversity and provision of net gains to biodiversity where possible (paragraph 109) and ensuring that Local Authorities place appropriate weight to statutory and non-statutory nature conservation designations, protected species and biodiversity The NPPF also considers the strategic approach which local authorities should adopt with regard to the protection, enhancement and management of green infrastructure, priority habitats and ecological networks, and the recovery of priority species Paragraph 118 of the NPPF comprises a number of principles which Local Authorities should apply, including encouraging opportunities to incorporate biodiversity in and around developments, provision for refusal of planning applications if significant harm cannot be avoided, mitigated or compensated for, applying the protection given to European sites to potential SPAs, possible SACs, listed or proposed Ramsar sites and sites identified (or required) as compensatory measures for adverse effects on European sites, and the provision for the refusal for developments resulting in the loss or deterioration of irreplaceable habitats unless the need for, and benefits of, the development in that location clearly outweigh the loss National policy therefore implicitly recognises the importance of biodiversity and that, with sensitive planning and design, development and 26

30 6.3. Local Policy conservation of the natural heritage can co-exist and benefits can, in certain circumstances, be obtained. North Cornwall Local Plan - Saved Policies District Councils within Cornwall became a unitary authority (Cornwall Council) in 1 st April Many of the planning policies that were used by the former districts have been saved until such time that a county wide Cornwall Local Plan is adopted There are three saved polices within the North Cornwall District related in whole or in part to nature conservation, policies ENV1, ENV4 and ENV5. Policies ENV4 and ENV5 are concerned with the protection of internationally, nationally and locally designated sites. Cornwall Local Plan The Cornwall Local Plan is comprised of a suite of documents including: Strategic Policies, Community Infrastructure Levy, Mineral Safeguarding Development Plan Document and the Allocation Development Plan Document. Strategic Policies There are five polices within the Local Plan Strategic Policies document that are related in whole or in part to nature conservation, policies 2, 22a, 23, 25, and PP10. Policy 2 is concerned with the protection and enhancements of environmental assets, including mitigation of unavoidable effects, appropriate and proportional to their value. Policy 22a is concerned with impacts upon biodiversity, while Policy 23 is concerned with designated sites of nature conservation, loss of biodiversity and protection of wildlife corridors. Policy 25 is concerned with green infrastructure, while Policy PP10 is concerned with the protection of national and international designations Discussion Measures have been suggested within this report to ensure that the development proposals will have no adverse effects on any statutory or non-statutory designated sites and as such the proposals will accord with policies ENV4, ENV5, 23, and PP10 of the saved policies, strategic policies and the principles laid down in the NPPF The majority of the features of greater ecological value within the site are to be retained, including all of the woodland and the majority of the hedgerows and trees. Where losses to the hedgerows and trees are to occur, these will be more than mitigated for through new hedgerow planting and through the planting of large numbers of new native trees. Losses to the wet issues within the site will be mitigated through the creation of a new lake complex which will diversify the habitats within the site and create new aquatic habitats within the site. As such the proposals 27

31 will accord with policies 2, 22a and PP10 of the strategic policies and the principles laid down in the NPPF Where the development proposals are likely to have an adverse effect on any protected species, works will only commence after a Natural England licence has been obtained and appropriate mitigation put in place. Although there will be some losses to the hedgerows within the site (a Priority Habitat), the planting of significant numbers of new native trees of an area far greater than that lost will mitigate for these losses. As such the proposals accord with policies 2, 22a and PP10 of the strategic policies In conclusion, implementation of the measures set out in this report would enable development of the site to accord with national and local planning policy for ecology and nature conservation. 28

32 7. SUMMARY AND CONCLUSIONS 7.1. was commissioned in to undertake an of the site at Camel Creak, Trevibban Farm, Cornwall for Pegasus Group The proposals for the study area are for a resort comprising up to 241 dwellings, with a swimming pool, a lake system, associated open space and landscaping The site was surveyed based around extended Phase 1 survey methodology, as recommended by Natural England. In addition, specific surveys were undertaken in respect of bats and Badgers A number of recommendations have been made to safeguard any designated statutory and non-statutory sites of nature conservation interest, and there are not considered to be any significant adverse effects on any designated sites as a result of the development proposals Four Badger setts are present within the site. Recommendations have been made to ensure that there is no adverse effect on the Badger setts as a consequence of the development proposals. Should any setts need to be closed / partially closed to accommodate the development proposals, a Natural England licence would be applied for 7.6. There are no trees or buildings within the site that have developed features suitable to support roosting bats The planting of new native hedgerows and large numbers of trees, the creation of new areas of wildflower grassland, the creation of new areas of wet grassland and the creation of a lake system will diversify the range of habitats present within the site and will provide enhanced opportunities for foraging bats, Badgers and invertebrates, while the erection of bat boxes on suitable retained trees will provide new roosting opportunities for bats within the site The above planting / habitat creation measures will also provide new and enhanced opportunities for nesting and foraging birds and a range of other wildlife e.g. invertebrates, while the erection of bird boxes within the site will also provide new nesting opportunities for birds Further recommendations have been made to safeguard other protected and notable species present within the site, including nesting birds. Recommendations have also been made to achieve ecological enhancements for such protected/notable species wherever possible In conclusion, through the implementation of the safeguards and recommendations set out within this report it is considered that the proposals accord with planning policy with regard to nature conservation at all administrative levels. 29
