A member of the Association of Wildlife Trust Consultancies. Extended Phase 1 Habitat Survey Summary AWT Ecological Consultancy was commissioned by the University of the West of England to carry out an Extended Phase 1 Habitat Survey of their land holding at Frenchay in north Bristol. The survey was undertaken on 16 and 17 March 2010, in cloud with occasional sunny periods. A further visit was made on 9 April A desk study was also conducted in order to assess existing records of designated sites and protected or notable species within the site and the surrounding area. The field survey and desk study results were used to facilitate an ecological assessment of the site, particularly its importance for Biodiversity Action Plan Habitats and protected species. Features identified as having the most significant nature conservation value are broad leaved woodland (UK, Avon and South Gloucestershire Council BAP Habitat), ponds (UK and Avon BAP Habitat), watercourse (Avon BAP Habitat), species-rich hedgerows (UK , Avon and South Gloucestershire Council BAP Habitat), veteran trees and species-diverse grassland (UK, Avon and South Gloucestershire Council BAP Habitat). The habitats within the site have the potential to support bats, great crested newts, reptiles, badgers and breeding birds. Please be aware that a survey of this nature can only provide a snapshot of the site's ecological importance. To provide more detailed information, the following protected species surveys have been recommended: Immediate great crested newt - presence/likely absence survey; Pending future development bats - activity surveys, also tree surveys if trees are to be removed or are subject to tree works; reptiles; badgers. AWT Ecological Consultancy April 2010 ii University of the West of England AWT065 Extended Phase 1 Habitat Survey In order to meet accepted standards of survey effort, the surveys listed above are subject to seasonal constraints. Depending on the survey results, mitigation measures may be required, and these may also be subject to seasonal constraints. It is recommended that a protected species survey programme be incorporated into any development timetable to include timing of survey work and any further works required in the event that protected species are found to be present. Please note that the survey results and any recommendations contained within this report will remain valid for one year following the date of survey.

The survey took place on 16 and 17 March 2010, with a further survey on 9 April 2010. The survey is required in order to inform the site's Biodiversity Action Plan and any future development proposals. 1.1.2 The university landholding is situated to the west of Frenchay in north Bristol, and is approximately 10.5ha in area. The central grid reference is ST623783. The main site is for the most part comprised of high-density modern buildings, hard-standing and ornamental areas, with trees and amenity grassland, but there are fields and hedgerows to the south-west and south-east of the main campus. Ponds and other water-bodies on the site as well as woodlands and veteran trees add further biodiversity interest. 1.1.3 The purpose of the survey was to identify habitats present within the site, and to assess the ecological status and value of these habitats, including their potential to support protected or otherwise notable species. Recommendations for further ecological surveys have been made based on the survey findings. . AWT Ecological Consultancy April 2010 1 University of the West of England AWT065 Extended Phase 1 Habitat Survey 2 Methodology 2.1 Ecological Assessment The ecological assessment was carried out in three stages: A desk study to collate records of designated sites and protected or otherwise notable species on the site and within the local area. A walkover field survey to identify habitats and their associated species and to assess the potential of the habitats to support protected or otherwise notable plant and animal species. Interpretation of the combined desk study and field survey results to assess the site's ecological status (presented under Discussion and Recommendations). 2.2 Desk Study 2.2.1 Biological data within 2km (designated sites, protected and otherwise notable species) was obtained from Bristol Regional Environmental Records Centre (BRERC - www.brerc.org.uk 2010 data). 2.3 Field Survey 2.3.1 The survey was conducted in accordance with best practice guidance (Institute of Environmental Assessment 1995. Guidelines for Baseline Ecological Assessment). 2.3.2 A walkover survey of the site was undertaken on 16 and 17 March and April 2010, during which habitats within the site were mapped and assessed for their ecological interest. The habitats were also assessed for their potential to support legally protected or otherwise notable flora and fauna. Where suitable habitat was identified on site, a search was conducted for field signs such as droppings, burrows, tracks and evidence of feeding that might indicate the presence of protected species, both at UK and European level. These habitats were also considered in relation to habitats immediately adjacent to the site. 2.3.3 Botanical nomenclature in this report follows that laid out by Stace (1997). AWT Ecological Consultancy April 2010 2 University of the West of England AWT065 Extended Phase 1 Habitat Survey 2.4 Constraints 2.4.1 The main walkover survey was carried out just before the optimum survey period, but many plant species were already evident. The further visit in April provided an additional check, so the survey is deemed to have been carried out during the optimal survey period. However, we were unable to identify an orchid species due to the time of year. AWT Ecological Consultancy April 2010 3 University of the West of England AWT065 Extended Phase 1 Habitat Survey 3 Results 3.1 Desk Study Designated Sites 3.1.1 The results of the data search for statutory designated sites within 2km of UWE are shown in Table 3.1 and also on Figure 2 - UWE Designated Sites. 3.1.2 There are no statutory sites found within the site boundaries. (The Severn Estuary Special Area of Conservation, a European designated site, lies within 10km of the site, but the site has no relevance in terms of the species for which it is designated). 3.1.3 There are no non-statutory sites found within the site boundaries, but there are six Sites of Nature Conservation Interest within 2km of the site boundaries. There are also two Regionally Important Geological/Geomorphological Sites within 2km, one at Stoke Park Estate to the south, and one to the east near Frenchay Common. Table 3.1 International Designated sites within 10km of UWE, UK designated sites and Locally Designated sites within 2km Designation Reasons for designation Special Area of Conservation Severn Estuary Waders and wildfowl, fish and Sabellaria reefs. Site of Nature Conservation Interest Stoke Park Woodland Semi-natural ancient woodland, neutral and calcareous grassland. Splatts Abbey Wood Semi-natural ancient woodland. Stoke Brook (tributary of River Flowing open water and bank-side vegetation. Frome) River Frome and Oldbury Court Flowing open water and bank-side vegetation, Estate woodland and grassland. AWT Ecological Consultancy April 2010 4 University of the West of England AWT065 Extended Phase 1 Habitat Survey Frenchay Common Neutral and acid grassland. Bonnington Walk Former allotments Protected and Notable Species records 3.1.4 The desk study returned numerous records of protected or otherwise notable species within 2km of the site, described in more detail below. 3.1.5 All protected species are mapped on Figure 3 Protected Species within 2km. Flora 3.1.6 There are many notable floral species within a 2km radius of the site. However, of these, only bluebell Hyacinthoides non-scripta was found on the site (Figure 1c). In addition, an orchid species found in several places growing in amenity grassland on the site may be the notable (locally uncommon) bee orchid Ophrys apifera, for which there are records within 2km. Mammals Badger 3.1.7 There are 47 badger Meles meles records within 2km of the site. Seven records occur on the site itself, mainly in the east/south-east, but also in the west. On the edge of the woodland, adjacent to car park 20, several holes which may have been formed by badgers were found (Target Note (TN) 1). In the south-eastern woodland many badger paths and other signs were found (TNs 3 and 4). Bats 3.1.8 There are 19 records for common/soprano pipistrelle Pipistrellus pipistrellus/pygmaeus, 9 for noctule Nyctalus noctula, 1 for brown long-eared Plecotus auritus, and 8 for Daubenton’s Myotis daubentonii within 2km of the site. Extending the search boundary to 5km from the site includes records for soprano pipistrelle, Leisler's bat Nyctalus leisleri, natterer’s bat Myotis nattereri and serotine Eptesicus serotinus. AWT Ecological Consultancy April 2010 5 University of the West of England AWT065 Extended Phase 1 Habitat Survey Water Vole 3.1.9 There are no water vole Arvicola terrestris records within 2km of the site. The habitats at UWE are not suitable for this species, which requires extensively interconnected rivers and other waterways with well-vegetated relatively steep banks. Otter 3.1.10 There are 4 records of otter Lutra lutra within 2km of the site. There is no suitable habitat at UWE as otters require larger water bodies than those found on site, with semi-natural connecting corridors to river habitat. Dormouse 3.1.11 There are no records of dormouse Muscardinus arvicola within 2km of the site. The habitats at UWE are not suitable for this species, which requires fairly extensive areas of interconnected ancient semi-natural woodland and species-rich hedgerows. Water shrew 3.1.12 There are 2 records for water shrew Neomys fodiens within 2km of the site. Although there are water bodies on site, they are not suitable for water shrews as the ditch is not well-enough vegetated, and the ponds are too isolated and lack suitable foraging areas. Hedgehog 3.1.13 There are 19 records for hedgehogs Erinaceus europaeus within 2km of the site. White-clawed crayfish 3.1.14 There are 12 records for white-clawed crayfish Austropotamobius pallipes within 2km of the site, on the River Frome. However, it is known from recent Avon Wildlife Trust surveys that this species is now probably extinct from the River Frome. 3.1.15 Although there are water bodies on the site, these are not suitable for this species, which requires clean flowing rivers and brooks with stony substrates. Birds 3.1.16 Records of notable birds are given in Table 3.3.

Amphibians Great crested newt 3.1.19 There are 53 records of great crested newt Triturus cristatus within 2km. The nearest record is within 500m of the site boundary, to the north-west. Other amphibian species recorded (Schedule 5 Wildlife and Countryside Act 1981) 3.1.20 There are records for smooth newts Triturus vulgaris and palmate newts Triturus helveticus, and toads Bufo bufo, within 2km of the site. 3.1.21 A small clump of frogspawn was noted in the eastern ditch. Two adult frogs Rana temporaria were found sheltering under debris in the southern woodland. Reptiles 3.1.22 There are 9 records for viviparous lizard Lacerta vivipara and 24 records for slow worm Anguis fragilis within 2km of the site. There are also 9 records for grass snake Natrix natrix and 2 records for adder Vipera berus within 2km of the site. 3.1.23 While there is suitable habitat for viviparous lizards and slow-worms on the site in the form of scrub, hedgerows and rank grassland, it seems unlikely that adders would be supported since there is little suitable habitat (dry stony ground and heathland). 3.1.24 The water bodies on the site, particularly those that are more natural in character such as the floodplain pond, the 'Ecopond' and the Wallscourt pond, and the ditch, may be suitable for grass snake. There is suitable terrestrial habitat in the form of hedgerows and woodlands. Invertebrates 3.1.25 Many notable invertebrate species have been recorded within a 2km radius of the site. AWT Ecological Consultancy April 2010 9 University of the West of England AWT065 Extended Phase 1 Habitat Survey 3.2 Field Survey Habitats and plants (Please refer to Phase 1 Habitat Map Figures 1a-f). Woodlands and Trees 3.2.1 There are several blocks of woodland at the site (TNs 2, 3 and 4). Several have been planted, but there are also woodlands that appear semi-natural in origin and may be fairly old, particularly bordering the south, north, west and south-east of the site (TNs 2, 3 and 4). 3.2.2 The planted woodland blocks are mainly dominated by sycamore Acer pseudoplatanus or ash Fraxinus excelsior, and in the blocks situated on top of the eastern bank of the ditch many trees of small-leaved lime Tilia cordata have been established. 3.2.3 . In the south-western hedgerows there are at least two veteran trees (TN 5). Across the site there are at least seven veteran trees, typically English oak Quercus robur and ash. These are mainly free-standing and are likely to derive from old hedgerows, or to be old field trees from the previous rural landscape. 3.2.4 Veteran trees are those with features of aging such as scars, holes, hollows and dead branches. Several were noted to have holes made by nesting woodpeckers. 3.2.5 Other veteran trees occur just south of Wallscourt Farm buildings, on the main campus east of B Block, and at the north-west corner of the site. Hedgerows 3.2.6 Near the Nursery building native bluebell was found in what would appear to be a remnant hedgerow. 3.2.7 The fields in the south-west of the site are divided by hedgerows consisting of a variety of native species, such as hawthorn Crataegus monogyna, blackthorn Prunus spinosa, hazel Corylus avellana, ash and field maple Acer campestre. Elder Sambucus nigra and willow species Salix spp. also occur (TN 6). In one very small block of trees near the Nursery building, likely to be a remnant of a field hedgerow, native bluebell was found. 3.2.8 The majority of these hedgerows appear to have grown up alongside field ditches, now dry, thus forming double rowed hedges. AWT Ecological Consultancy April 2010 10 University of the West of England AWT065 Extended Phase 1 Habitat Survey 3.2.9 Elsewhere the hedgerows on site are planted, consisting of beech Fagus sylvatica and blackthorn where native; other hedgerows containing ornamental non-native species. Species-rich Grassland 3.2.10 The majority of the site does not consist of this habitat type but there are four areas where the botanical interest is greater. Currently these are managed as amenity grassland (i.e. regularly cut). 3.2.11 One such site is the small area of grassland just south of the Wallscourt pond (TN 7). Cowslip Primula veris is abundant here. 3.2.12 The most interesting area is an amenity-cut man-made bank immediately north of the main entrance (TN 8). The origin of the soil is unknown. 3.2.13 Both banks of the ditch in the east of the site are also more diverse. Here as well as many of the species listed above, carnation sedge Carex panicea was recorded and, in damper areas, cuckooflower Cardamine pratensis. The most speciesdiverse areas are within 5 metres of the watercourse on both sides. 3.2.14 A small area in the north of the south-western fields was also of interest, where there was abundant self-heal and ox-eye daisy, and occasional common knapweed Centaurea nigra. As this area is not regularly mown it appears on the Phase 1 map as semi-improved grassland. Rank grassland 3.2.15 The fields in the south-west consist of rank grassland dominated by the grasses cock's-foot Dactylis glomerata and Yorkshire fog (TN 9). 3.2.16 Other species found here are typical of agriculturally improved fields such as creeping buttercup Ranunculus repens, hogweed Heracleum sphondylium, white clover and daisy. 3.2.17 The central-eastern field is slightly more diverse (TN 10). 3.2.18 The south-eastern field also consists of rank semi-improved grassland (TN 11). Amenity grassland 3.2.19 The more formal areas of the site consist of regularly mown grass, almost certainly seeded (TN 12). These border buildings, paths, roads and car parks, and formally managed areas around site entrances. AWT Ecological Consultancy April 2010 11 University of the West of England AWT065 Extended Phase 1 Habitat Survey 3.2.20 In the main such grasslands are species-poor, supporting only daisy, white clover, buttercups and dandelion Taraxacum agg. 3.2.21 However, of significance are the several occurrences of a species of orchid (as indicated on the Phase 1 maps). Only the basal leaves were evident at this time of year, but it is likely to be bee orchid or possibly green-winged Orchis morio (TN 13). 3.2.22 In a limited number of areas, the amenity grassland shows slightly greater botanical diversity, with selfheal and, in less well-drained areas, cuckooflower. Ornamental trees and shrubs 3.2.23 Associated with the formal areas of amenity grassland are borders of ornamental shrubs and trees (TN 14). 3.2.24 Some of the planted trees are native, while many are non-native in origin. Invasive plant species No invasive plant species were observed. Water-bodies 3.2.25 There are several ponds on the holding, four within the main campus, one in the north-west, and another south-west of Wallscourt Farm. 3.2.26 A ditch flows in a northerly direction in the east of the site. 3.2.27 In the north-west of the site, on the 1000 year floodplain, is a relatively large flood attenuation pond (TN 15), to the north of which is a ditch carrying water off site via a culvert. The marginal species consist of a large stand of bulrush Typha latifolia with occasional yellow iris Iris pseudacorus, and a single clump of marsh marigold Caltha palustris. 3.2.28 The surrounding grassland, although regularly mown, has enough floral diversity to be considered semi-improved. 3.2.29 At the south-west corner of the main campus is a pond which also appears quite natural and is known as the site's Ecopond (TN 16). An interpretation board is present. 3.2.30 To the south-west of Wallscourt Farm buildings is a pond which has been used for fishing and is currently known as the Hewlett Packard pond (TN 7). 3.2.31 A small ornamental pond is situated between car parks 1 and 2 (TN 18). AWT Ecological Consultancy April 2010 12 University of the West of England AWT065 Extended Phase 1 Habitat Survey 3.2.32 Another small ornamental pond exists between Blocks P and Q. (TN 19); this pond contains fish. 3.2.33 In a poorly draining field in the south-western section of the holding is a small shallow body of water. This is probably only a temporary pond (TN 20). 3.2.34 Running south to north in the east of the site is a watercourse, culverted at either end and likely to be a remnant of a tributary of the River Frome (TN 21). The southern end of the watercourse in the east of the site forms a large lake (TN17). Buildings 3.2.35 The main buildings of Wallscourt Farm and its associated out-houses are built in the traditional style using stonework and slates (TN 22). 3.2.36 The majority of the campus consists of modern buildings with much use of prefabricated materials. AWT Ecological Consultancy April 2010 13 University of the West of England AWT065 Extended Phase 1 Habitat Survey 4 Discussion and Assessment 4.1 Designated Sites It is considered extremely unlikely that any development on the UWE landholding or change in site management would have any negative impact on any of the Sites of Nature Conservation Interest within a 2km radius of the site. 4.2 Habitats and Flora 4.2.1 Features identified as having the most significant nature conservation value are broad leaved woodland (UK, Avon and South Gloucestershire Council BAP Habitat), ponds (UK and Avon BAP Habitat), watercourse (Avon BAP Habitat), species-rich hedgerows (UK , Avon and South Gloucestershire Council BAP Habitat), veteran trees and species-rich grassland (UK, Avon and South Gloucestershire Council BAP Habitat). 4.2.2 Native bluebell is a UK BAP species and is also protected under the Wildlife and Countryside Act 1981. 4.2.3 Bee orchid is a locally uncommon species, green-winged orchid (should the orchid prove to be either of these species) is a locally scarce species. 4.3 Fauna 4.3.1 The site has significance for the following protected species Bats 4.3.2 There are seventeen species of bats in the UK, all of which are protected by European law through The Conservation (Natural Habitats, &c.) Regulations 1994 (better known as the Habitats Regulations) making them 'European Protected Species'. Bats are afforded legal protection in the UK under the Wildlife and Countryside Act 1981 (as amended by the Countryside and Rights of Way Act 2000) Schedule 5 Section 9, which protects bats from intentional killing, injuring or taking, and protects their roosts in England, Scotland and Wales. 4.3.3 The UK Biodiversity Action Plan identifies brown long-eared bat, soprano pipistrelle bat, noctule bat as UK BAP priority species. The Avon Biodiversity Action Plan identifies all bats as Local BAP priority species. AWT Ecological Consultancy April 2010 14 University of the West of England AWT065 Extended Phase 1 Habitat Survey 4.3.4 All of the above species have been recorded with a 5km radius of the site boundaries. Common or soprano pipistrelle, noctule, Daubenton’s, and brown long-eared bat have also been recorded within 2km of the site boundaries. There are no records of bats on the site itself. Bats in Trees 4.3.5 A significant number of the site's veteran trees possess features such as cracks, splits, loose bark, and in particular woodpecker holes that might provide suitable roosting locations for bats. This includes trees with a dense cover of ivy (ivy is known to be used for roosting by bats). Should bats be utilising the local area, it is possible that they might be using some of the site's trees for roosting. Foraging bats 4.3.6 The several areas of woodland and hedgerows found along the boundaries of the site have potential to provide foraging habitat for bats that might be present in the local area. Also the habitat in the south-east corner of the site which consists of pasture enclosed by woodland, hedgerows and scrub. 4.3.7 The connectivity with the greatest potential for bat commuting is provided by the hedgerows in the south-west of the site, as these have a direct link with the Long Wood broad-leaved woodland complex of Stoke Park Estate, to the south of the site. Bats in Buildings 4.3.8 The older buildings of Wallscourt Farm and its outbuildings have pitched roofs, and some may conceal roof voids that could be suitable for roosting bats. 4.3.9 The majority of the campus buildings afford low/negligible potential to support roosting bats. Nesting Birds 4.3.10 Statutory protection is given to nesting birds in the UK under the Wildlife and Countryside Act 1981 (as amended) which makes it an offence to intentionally kill, injure or take any wild bird or take, damage or destroy its nest whilst in use or being built, or take or destroy its eggs. In addition to this, for species listed on Schedule 1 of the Act, it is an offence to intentionally or recklessly disturb them while they are nest building or at or near a nest with eggs or young, or to disturb the dependent young of such a bird. AWT Ecological Consultancy April 2010 15 University of the West of England AWT065 Extended Phase 1 Habitat Survey 4.3.11 The woodlands, hedgerows, old trees, scrub and even the denser areas of ornamental vegetation all have the potential to support nesting birds. Badgers 4.3.12 Badgers are protected under the Badgers Act 1992. This makes it an offence to wilfully kill, injure, take, possess or ill-treat a badger, or to attempt to do so; or to intentionally or recklessly interfere with a sett. Sett interference includes disturbing badgers whilst they are occupying a sett, as well as damaging or destroying a sett or obstructing access to it. 4.3.13 The many signs of badger activity in the south-east of the site, along with the density of badger records to the east and south of the site, confirm that the woodlands and fields in this area are important badger foraging territories. In addition, the badger records from the Business Park, and those in the western section of the site, suggest that badgers would be found across the campus both directly foraging and to gain access to their potential foraging territory in the west. 4.3.14 It would appear that the construction of the M32 bisected the habitats of badger populations using the Frome Valley and the woodlands to the west, with further loss of territory caused by the development of the university campus, the Business Park, housing and the complex at AXA. Hedgehogs 4.3.15 There is much potential habitat at UWE (woodland, hedgerows, grasslands and shrub beds) to support this species, which has declined so much in recent years that it is now listed in the Red Data Book and is a South Gloucestershire Council BAP species. Amphibians 4.3.16 Great crested newts are European Protected Species and as such are protected by the Conservation (Natural Habitats & c.) Regulations 1994, which implements the Habitats Directive. With regard to UK law, the species is afforded protection under Schedule 5, Section 9 (all parts) of the Wildlife and Countryside Act 1981 (as amended). Great crested newts are also listed as UK, Avon and South Gloucestershire BAP priority species, and as Species of Principal Importance under the NERC Act 2006. AWT Ecological Consultancy April 2010 16 University of the West of England AWT065 Extended Phase 1 Habitat Survey 4.3.17 Common toad was added to the list of UK BAP priority species in September 2007 and is also an Avon BAP species. 4.3.18 Smooth and palmate newts, common frog and common toad are protected under Schedule 5 of the Wildlife and Countryside Act 1981 against being sold. 4.3.19 The ponds with the most natural appearance (i.e. vegetated edges, grass or scrub surroundings and green corridor connections to other ponds) have the potential to support great crested newts. Even ponds which appear to have low potential should be checked, as this species will use sub-optimal habitat in the absence of more preferred sites. 4.3.20 The ponds also have the potential to support smooth and palmate newts, and frogs and toads, although the latter is likely to be restricted to the larger water-bodies. 4.3.21 The presence of great crested newt records within less than 500m to the north of the site, in the Harry Stoke area, implies that any suitable habitat within the UWE landholding may be used by this species, which requires several interconnected ponds to sustain its population. Reptiles 4.3.22 The six species of native reptiles within the UK are protected under the Wildlife and Countryside Act 1981 (as amended) and are all UK BAP priority species. The four most frequently encountered reptiles; adder, grass snake, common or viviparous lizard and slow-worm are protected against killing and injuring under Schedule 5 of the Wildlife and Countryside Act 1981. Slow-worm is a UK, Avon and South Gloucestershire Council BAP species. 4.3.23 The rank grassland and hedgerows have the potential to support foraging slowworms, viviparous lizards and grass snakes. The wetland areas have the potential to be inhabited by grass snakes. Invertebrates 4.3.24 The semi-natural areas at the site such as the native species of the woodlands and hedgerows provide food plants for invertebrate larvae. And some exotic shrubs provide nectar favoured by many adult insects. Therefore the site will have some value for native invertebrates. 4.3.25 The records show that there are many notable invertebrates in the surrounding area, especially moth species, but without a specialist invertebrate survey, it is not AWT Ecological Consultancy April 2010 17 University of the West of England AWT065 Extended Phase 1 Habitat Survey possible to say whether any of these species might occur at the site. However, species-rich grasslands tend to support the greatest diversity of insects, and this habitat is very scarce at the UWE landholding. AWT Ecological Consultancy April 2010 18 University of the West of England AWT065 Extended Phase 1 Habitat Survey 5 Conclusions 5.1 Designated Sites 5.1.1 It is considered that any development on the survey site is unlikely to have an impact on any nearby designated sites as there is little direct connection between such sites and the UWE landholding. 5.1.2 However, one possible exception is the drainage from the floodplain pond; this would appear to exit the UWE site onto the site of Splatts Wood. It is not possible at this stage to be definitive about this potential risk. 5.2 Habitats and Species The most ecologically significant habitats on site are the blocks of native semi-natural woodland and the hedgerows, particularly those in the south-west of the site. The ditch and the most natural ponds are also of ecological importance. 5.2.1 Some small areas of grassland have been show to have characteristics of more species-rich grassland, but these areas are currently limited in their extent. 5.2.2 The Phase 1 survey has demonstrated the presence of the protected species badgers on the UWE landholding. 5.2.3 It has also demonstrated the potential presence of the protected species bats, great crested newts, slow-worms and grass snakes on the site. AWT Ecological Consultancy April 2010 19 University of the West of England AWT065 Extended Phase 1 Habitat Survey 6 Recommendations 6.1 Bats Bats in trees 6.1.1 Several trees, in particular the veteran trees, within the site were considered to have medium to high potential to support roosting bats. It is recommended that all trees within the site are assessed in order to determine their potential to support roosting bats and provide baseline data for use in planning future tree works. 6.1.2 In the event of future development and/or tree works taking place, any trees likely to be affected with identified features with medium to high potential to support roosting bats should be fully inspected for bats. This would require a skilled tree climber to assess the tree using ropes and a ladder where necessary to inspect features that are not accessible from the ground. The inspection would be carried out under the supervision of an ecologist with experience in assessing trees for their potential to support roosting bats. Bats in Buildings 6.1.3 Before any building works, including demolition, take place that may affect the fabric of the site buildings, particularly the buildings of Wallscourt Farm, it is recommended that consideration be given to assessing the buildings' potential to support roosting bats. 6.1.4 Should potential to support roosting bats be identified, the buildings should be inspected. An inspection survey would involve a full visual inspection of the interior and exterior of the building using ladders where necessary to access features at height. During the survey the building would be inspected for any features that may provide roosting sites with bats, along with any signs of bat usage such as droppings, scratch marks, urine staining, or grease marks. Foraging bats 6.1.5 In the event of future development taking place that is likely to affect the site's boundary habitats, especially the areas of woodland and hedgerows, it is recommended that a bat activity survey be conducted in order to assess the abundance, and patterns of activity, of any bats that may be using the site. AWT Ecological Consultancy April 2010 20 University of the West of England AWT065 Extended Phase 1 Habitat Survey 6.1.6 The bat activity survey would require two or three separate dawn and/or dusk surveys, with at least one consisting of a dusk and dawn survey within one 24-hour period. The survey would involve an ecologist/s walking potential foraging and navigational routes within the site using a bat detector to detect the echolocation calls of any bats that may be present. The surveys should be conducted between April and September inclusive. 6.2 Nesting Birds 6.2.1 It is recommended that all scrub and tree clearance works should be conducted outside of the breeding and nesting season (generally considered to be March to September inclusive). 6.2.2 Where it is not possible to conduct these operations outside the nesting season, the trees and scrub to be cleared should be inspected by an ecologist immediately prior to works commencing. 6.2.3 In the event of nesting birds being found in vegetation to be cleared, works should cease. The vegetation in question should be cordoned off to a radius of 10m. No works shall be allowed to commence until an ecologist has confirmed that breeding or nesting birds are no longer present. 6.3 Reptiles 6.3.1 In the event of future development taking place within areas identified with the potential to support reptiles, it is recommended that a reptile presence / absence survey is carried out to determine presence or likely absence of reptiles. 6.3.2 This survey would involve placing artificial refugia made of corrugated steel, heavyduty black rubber or bitumen roofing felt within the area. Refugia would be checked during suitable weather conditions at intervals of between 3 and 12 days for a minimum of 7 visits. Natural England guidelines recommend that reptile surveying be carried out in late March to April or in September. Should any reptiles be found during the survey, further mitigation may be required. Depending on the numbers and species of reptile present, and the details of the development, further mitigation may involve habitat creation and/or translocation/relocation of reptiles. AWT Ecological Consultancy April 2010 21 University of the West of England AWT065 Extended Phase 1 Habitat Survey 6.4 Badgers 6.4.1 In the event of future development, the exact use of the site by badgers for foraging would need to be established by a full badger survey, to include the surrounding land up to 500m where suitable habitat exists. 6.4.2 The location of signs of badger activity should be recorded and mapped, including setts, runs, latrines, footprints, snaffle holes, digging, scratching trees and hair on fences and sharp vegetation such as brambles. In the event of future development, this will provide a picture of badger utilisation of the site and also inform ecological management decisions relating to the site 6.4.3 The best times of year to survey for badger activity are spring and autumn when activity levels are relatively high and vegetation growth is limited. 6.5 Great crested newts 6.5.1 If any of the ponds, or newt-friendly habitat within 500m, support this species and are likely to be affected by proposed development, full population surveys will be required in order to inform a development licence. 6.5.2 A population survey would require six surveys to be carried out between March and June, using at least three methods from; egg searching, torchlight survey, refugia searching, netting and bottle trapping.

Badger use of the site was confirmed by the finding of a typical badger hair. It is likely that the sett is disused, at least at the present time (badgers can abandon a sett and then open it up again at a later date according to the need of the population). Although there were relatively recent spoil heaps, the (at least half a dozen) holes did not have the characteristic D shape of badger sett entrance holes. Rabbit Oryctolagus cuniculus droppings were found and it seems most probable that the original badger entrance holes and tunnels have partially collapsed, but been kept open to a smaller extent by rabbit use. On inspection, the holes led to tunnels which quickly narrowed only a short distance inside, further confirming the lack of recent use by badgers.

AWT Ecological Consultancy April 2010 25 University of the West of England AWT065 Extended Phase 1 Habitat Survey Target Note 2 Habitat Type: Broad-leaved woodland Plate 3: Broad-leaved woodland There are several blocks of broad-leaved woodland adjacent to or bordering the perimeters of the site. An example is the woodland bordering the north of the western section of the main campus, which leads down to the floodplain. The woodland appears to be mainly secondary and consists of predominantly native species. Dominated by sycamore Acer pseudoplatanus and/or ash Fraxinus excelsior, occasional pedunculate oak Quercus robur, English yew Taxus baccata and field maple Acer campestre are also present. The understory consists of frequent hazel Corylus avellana coppice, hawthorn Crataegus monogyna, blackthorn Prunus spinosa, wild privet Ligustrum vulgare, dogwood Cornus sanguinea and rarely, spindle Euonymus europaeus. Ivy Hedera helix is the dominant species of the ground flora, and other species include frequent lords-and-ladies Arum maculatum and occasional stinking iris Iris foetidissima. Habitat status: UK, Avon and South Gloucestershire Council BAP habitat. Habitat management: Not known. Potential likelihood to support protected species: Foraging badgers, foraging bats, nesting birds, great crested newts, slow-worms and grass snakes. AWT Ecological Consultancy April 2010 26 University of the West of England AWT065 Extended Phase 1 Habitat Survey Target Note 3 Habitat Type: Broad-leaved Woodland at boundary with Filton Cemetery Plate 5: Woodland Plate 4: Woodland This is a small block of linear mixed broad-leaved plantation woodland forming the boundary with Filton Cemetery. A diverse range of mostly native broad-leaved tree species characterise this area, including ash, pedunculate oak, hazel, field maple, hawthorn, elder Sambucus nigra, spindle, wild privet, goat willow Salix capraea and crack willow Salix fragilis. Nonnative species found include: sycamore, European larch Larix decidua, Turkey oak Quercus cerris, horse chestnut Aesculus hippocastanum and lime Tilia x europaea. The generally impoverished ground flora is dominated by ivy, lords-and-ladies and common nettle Urtica dioica. However, some small patches of bluebell Hyacinthoides non-scripta occur in the north west corner. These have probably been here since this area formed part of a now defunct hedged boundary. Rabbit activity is found throughout the woodland, but is most extensive in the northern section of woodland. There are signs of badger activity throughout the woodland, including trails, snuffle holes, and hair samples found within spoil formed around some of the rabbit hole entrances found along the northern boundary (TN 1). Habitat status: UK, Avon and South Gloucestershire Council BAP Habitat. Habitat management: Not known. Potential likelihood to support protected species: Badgers, foraging bats, slow-worms, nesting birds, great crested newts. AWT Ecological Consultancy April 2010 27 University of the West of England AWT065 Extended Phase 1 Habitat Survey Target Note 4 Habitat Type: South-eastern Broad-leaved Woodland Plate 6: Eastern woodland edge from Plate 7: Badger hair sample on eastern adjacent UWE landholding boundary fence This small area of mixed broad-leaved plantation woodland forms part of a more extensive area of adjacent woodland found outside the UWE landholding. Like the woodland parcel found to the north (TN 1), this area comprises a diverse range of mostly native broad-leaved trees species with pedunculate oak, field maple and European larch commonly occurring. Like the woodland area found to the north, there are signs of badger activity throughout the woodland, including trails, snuffle holes, and hair samples, notably a small bundle of badger hair found caught on the eastern boundary fence line (Plate 7 above). Habitat status: UK, Avon and South Gloucestershire Council BAP Habitat. Habitat management: Not known. Potential likelihood to support protected species: Badgers, foraging bats, slow-worms, grass snakes, nesting birds, great crested newts. AWT Ecological Consultancy April 2010 28 University of the West of England AWT065 Extended Phase 1 Habitat Survey Target Note 5 Habitat Type: Veteran trees Plate 8: Veteran trees with woodpecker holes This specimen, pedunculate oak, was found in one of the south-west field hedgerows. Like several of the other veteran trees, old woodpecker holes were noted. These can be frequented by certain bat species such as noctule bats. Other typical features that may attract bat use are crevices, rot holes and areas where bark has lifted away from the trunk. In addition dense ivy may provide dayroosting opportunities for bats. Habitat status: None Habitat management: oNone None apparent, although it is likely that the trees are subject to Health and Safety inspections with subsequent safety works as necessary. Potential likelihood to support protected species: Roosting bats and nesting birds. AWT Ecological Consultancy April 2010 29 University of the West of England AWT065 Extended Phase 1 Habitat Survey Target Note 6 Habitat Type: Native hedgerow Plate 9: Native hedgerow Plate 10: Ditch There are several native hedgerows across the site, but mainly found bordering the fields in the south-west and the east of the site. The hedges in the south-western fields consists of hawthorn, ash, willow sp., blackthorn, hazel (often old coppice) and field maple. They appear to be formed from scrub which has grown up around old ditches, largely now dry. The number of species per unit length of hedgerow, linkages with other native hedgerows, and association with ditches, lead these hedgerows to be assessed as important under the Hedgerow Regulations. This means that Hedgerow Removal Notices will need to be submitted to the Local Authority for permission to remove them, although their being left in situ and buffered within any new development would be advised in terms of maintaining the biodiversity interest at the site. Habitat status: Species-rich hedgerows are UK, Avon and South Gloucestershire Council BAP Habitats. They are also protected under the Hedgerow Regulations 1997. Habitat management: Not known. Potential likelihood to support protected species: Foraging and commuting bats, grass snakes, slow-worms and common lizard, foraging bats, great crested newts, nesting birds. AWT Ecological Consultancy April 2010 30 University of the West of England AWT065 Extended Phase 1 Habitat Survey Target Note 7 Habitat Type: Wallscourt Pond Plate 11: Pond This rectangular, stone-lined pond has been used in the past by Hewlett Packard staff as a fishing lake. Well-spaced ash and goat willow surround the pond. The marginal vegetation consist of clumps of common reed Phragmites australis, but there did not appear to be any emergent or submerged plant species. The water is opaque, with a grey-green tinge, suggesting that it is subject to considerable eutrophication (an overgrowth of algae caused by excessive nutrient input). We were informed that there are carp in the pond, which could account for the nutrient richness (their excretion) and the opaqueness of the water (they are bottom feeders and constantly stir up silt). Cowslips Primula veris grow in the adjacent grassland. Habitat status: UK and Avon Biodiversity Action Plan Habitat. Habitat management: Grass is cut right up to the edge of the pond. Potential likelihood to support protected species: Foraging bats, great crested newts, grass snakes, nesting birds. AWT Ecological Consultancy April 2010 31 University of the West of England AWT065 Extended Phase 1 Habitat Survey Target Note 8 Habitat Type: Semi-improved Neutral Grassland Plate 12: Area of species-rich grassland A bank of grassland to the north of the main entrance consists of species-rich grassland. It's provenance is not known, but it is possible that the bank was made up with imported or on site material which contained an assemblage of less common plants, i.e. was species-rich grassland. Red fescue Festuca rubra is the dominant grass species, with abundant Yorkshire fog Holcus lanatus. Self-heal Prunella vulgaris and ribwort plantain Plantago lanceolata are the most abundant herbs, with frequent creeping cinquefoil Potentilla repens, ground-ivy Glechoma hederacea, white clover Trifolium repens and daisy Bellis perennis, occasional germander speedwell Veronica chamaedrys and common mouse-ear Cerastium fontanum, and rarely (and of most interest), an orchid species, ox-eye daisy Leucanthemum vulgaris, lady's bedstraw Galium verum and corky-fruited water-dropwort Oenanthe pimpinelloides. Habitat status: None Habitat management: Frequent cutting as amenity grassland. Potential likelihood to support protected species: Very limited, possibly basking slowworms, grass snakes and invertebrates. AWT Ecological Consultancy April 2010 32 University of the West of England AWT065 Extended Phase 1 Habitat Survey Target Note 9 Habitat Type: Rank grassland Plate 13: Field with rank grassland This field in the south-west of the site consists of rank i.e. dense and overgrown grassland. The dominant grass species are cock's-foot and Yorkshire fog. Supporting only widespread and common species such as daisy, white clover, buttercup, hogweed, docks and nettles, most of these fields consist of improved grassland, grading to semi-improved with the addition of common mouse-ear and ribwort plantain. Habitat status: None Habitat management: Cut, with the cuttings left in situ. Potential likelihood to support protected species: Slow-worms and grass snakes, hunting ground for birds of prey such as kestrel. AWT Ecological Consultancy April 2010 33 University of the West of England AWT065 Extended Phase 1 Habitat Survey Target Note 10 Habitat Type: Central-Eastern field Plate 14 : Rank field with shorter rabbitgrazed turf (inset) The field consists of rank grassland, i.e. dense tall grasses, dominated by cock's-foot and Yorkshire fog. The few plant species present include hogweed, docks, nettles and creeping thistle with occasional ribwort plantain and common mouse-ear. This species assemblage would lead it to be assessed as semi-improved grassland. A slightly more species-rich area occurs in the central-eastern section of the field, which appears to be intensively rabbit-grazed (many droppings are present). Here there is carnation sedge Carex panicea, self-heal and ox-eye daisy, giving it characteristics of semi-improved neutral grassland. The far eastern end of the field is dominated by dense bramble Rubus fruticosus agg. scrub. The southern boundary is formed by an old hedge, (the sparse line of old hawthorns to the west appears to be a continuation of this feature), where there was a spoil mound and holes suggestive of another disused badger sett, currently used by rabbits. Habitat status: None Habitat management: Field is cut infrequently. Potential likelihood to support protected species: Badger foraging, slow-worm, grass snake, nesting birds in scrub and hedgerow, hunting ground for birds of prey such as kestrel. AWT Ecological Consultancy April 2010 34 University of the West of England AWT065 Extended Phase 1 Habitat Survey Target Note 11 Habitat Type: Semi-improved grassland Plate 15: Semi-improved grassland looking south L-shaped, fenced off area of species poor semi-improved rank grassland. Dominant grass species include cock's-foot, common bent Agrostis capillaris and red fescue. Commonly occurring forbs include common sorrel Rumex acetosa, ribwort plantain, dandelion Taraxacum agg. and creeping buttercup Ranunculus repens. Other forbs found include: broad-leaved plantain Plantago major, meadow buttercup Ranunculus acris, creeping cinquefoil, common mouse-ear, white clover, common daisy, lesser celandine Ranunculus ficaria and carnation sedge (rare). A small area of tall ruderal vegetation occurs in the northern end of this area, characterised by creeping thistle Cirsium arvense, common nettle and spear thistle Cirsium vulgare. The larger expanse of grassland found to the south of this area is for the most part species-poor improved grassland dominated by perennial rye grass Lolium perenne. Small patches of vegetation more characteristic of species poor semi-improved grassland, as described above, occasionally occur within the sward. Habitat status: None Habitat management: Not known Potential likelihood to support protected species: foraging badgers and bats, slowworms, hunting ground for birds of prey such as kestrel. AWT Ecological Consultancy April 2010 35 University of the West of England AWT065 Extended Phase 1 Habitat Survey Target Note 12 Habitat Type: Amenity grassland Plate 16: Amenity grassland The majority of the amenity grassland on the site consists of the grasses cock's-foot and Yorkshire fog, with daisy, white clover and creeping buttercup. However, there are some areas, indicated on the Ph1 map, which have developed a slightly more diverse species assemblage, causing them to be assessed as semiimproved grassland or even poor semi-improved neutral grassland. On these areas species such as common mouse-ear, cuckooflower Cardamine pratensis, ox-eye daisy and self-heal occur. The extensive swathes of level grasslands within 5 metres of the ditch in the east of the site are a good example of these more species-rich areas, and in addition to the species above, also support carnation sedge. Habitat status: None Habitat management: Frequent mowing. Potential likelihood to support protected species: Possibly basking slow-worms and grass snakes. AWT Ecological Consultancy April 2010 36 University of the West of England AWT065 Extended Phase 1 Habitat Survey Target Note 13 Habitat Type: Amenity grassland with orchids Plate17: Orchid leaves The majority of the amenity grassland on the site consists of the grasses cock's-foot and Yorkshire fog, with daisy, white clover and creeping buttercup. However, there are some areas, indicated on the Phase 1 map (Figures 1a-f), where orchids grow. As just the base leaves were visible at the time of survey, it is difficult to make an identification as yet, but the most likely species are bee orchid Ophrys apifera or green-winged orchid Orchis morio. Bee orchids are locally uncommon, while green-winged orchids are locally scarce. Future management of these grasslands could be altered to enable the orchids to flower. Habitat status: None Habitat management: Frequent mowing. Potential likelihood to support protected species: Possibly basking slow-worms and grass snakes. AWT Ecological Consultancy April 2010 37 University of the West of England AWT065 Extended Phase 1 Habitat Survey Target Note 14 Habitat Type: Ornamental shrubs with trees Plate 18: An example of ornamental shrubs and trees Forming borders in and around car parks and adjacent to roads and buildings, are extensive areas consisting of non-native shrubs and trees. Occasionally native trees have been formally planted, such as silver birch Betula pendula, but the majority of species are non-native and therefore of very limited value to wildlife. Habitat status: None Habitat management: Regular maintenance. Potential likelihood to support protected species: Nesting birds, possibly slow-worms and grass snakes, badgers (especially within more extensive areas along the northern boundary). AWT Ecological Consultancy April 2010 38 University of the West of England AWT065 Extended Phase 1 Habitat Survey Target Note 15 Habitat Type: Pond on 1000 year floodplain Plate :Pond (marsh marigold in insert) Plate 19: Floodplain pond with marsh marigold (inset) Although there are trees bordering the pond, they are not casting enough shade to limit the pond's wildlife value. There are swathes of bulrush Typha latifolia forming the marginal vegetation, with occasional marsh marigold Caltha palustris and yellow flag iris Iris pseudacorus. To the north of the pond runs a partially culverted drain, bringing water from the site, the pond acting as an overflow reservoir. Habitat status: Ponds are UK and Avon BAP habitats. Habitat management: Not known. Potential likelihood to support protected species: Great crested newts, grass snakes, foraging bats. AWT Ecological Consultancy April 2010 39 University of the West of England AWT065 Extended Phase 1 Habitat Survey Target Note 16 Habitat Type: Ecopond Plate 20: Ecopond with Interpretation Board This pond is reputed to be an old farm pond. The marginal vegetation consists of hard rush Juncus inflexus, soft rush Juncus effusus, marsh marigold and yellow flag iris. Mare's-tail Hippuris vulgaris is the emergent species, forming a dense tangle of aquatic stems at the northern end of the pond, and the main submerged species is rigid hornwort Ceratophyllum demersum. Information from site workers suggests that the pond has been much used in the past by frogs although no spawn was evident at the time of survey. However, two frogs were found under some hardboard debris adjacent to the woodland to the east of the pond. New development now lies immediately outside the fence on the western boundary, where open fields had existed until last year or so. Habitat status: Ponds are UK and Avon BAP habitats. Habitat management: Not known. Potential likelihood to support protected species: Great crested newts, grass snakes, foraging bats. AWT Ecological Consultancy April 2010 40 University of the West of England AWT065 Extended Phase 1 Habitat Survey Target Note 17 Habitat Type: Water course lake Plate 21: Pond at southern end of ditch Plate 22: Corky-fruited water-dropwort At the southern end of the ditch the water has been dammed to form an ornamental lake. The marginal vegetation consists of infrequent stretches of common reed with occasional hard rush. There does not appear to be much emergent or submerged vegetation. The lake supports water birds such as coot, mallard and Canada goose. Abundant corky-fruited water-dropwort was growing on the surrounding amenity grassland. It is not known whether this may have been planted. Habitat status: Ponds are UK and Avon BAP habitats. Habitat management: Grass cut to water's edge. Potential likelihood to support protected species: Grass snakes, unlikely to be great crested newts as there are likely to be fish in a water body of this area, foraging bats. AWT Ecological Consultancy April 2010 41 University of the West of England AWT065 Extended Phase 1 Habitat Survey Target Note 18 Habitat Type: Ornamental pond Plate 23: Ornamental pond This pond is stone-lined, with stone walls and paving on most of the perimeter. Much of the upper banks are covered in the ornamental shrub Cotoneaster horizontalis. However, it has gained a more semi-natural appearance through the development of a marginal vegetation consisting of common reed, bulrush and yellow iris. The emergent vegetation consists of water mint Mentha sp. and marsh marigold. The submerged species include the non-native Nuttall's pondweed Elodea nuttallii. There was no evidence of use by amphibians at the time of survey. Habitat status: Ponds are UK and Avon BAP habitats. Habitat management: Not known. Potential likelihood to support protected species: Great crested newts, grass snakes, foraging bats. AWT Ecological Consultancy April 2010 42 University of the West of England AWT065 Extended Phase 1 Habitat Survey Target Note 19 Habitat Type: Ornamental pond between Blocks P and Q Plate 24: Ornamental pond This pond is completely surrounded by stone paving, making it less suitable for wildlife than if it had a vegetated edge. It contains fish, which makes it unlikely that great crested newts would survive for long in it. It is quite isolated from other water bodies and is without any vegetated corridors leading to other more suitable water bodies. Habitat status: Water bodies are a UK and Avon BAP habitat. Habitat management: The grass is cut to the edges of the water. Potential likelihood to support protected species: Limited potential for great crested newts. AWT Ecological Consultancy April 2010 43 University of the West of England AWT065 Extended Phase 1 Habitat Survey Target Note 20 Habitat Type: Pond (and poorly drained grassland) Plate : Pond with damp grassland Plate 25 : Temporary pond In the northern centre of the SW fields, lies an area of poorly drained grassland, where a shallow depression has enabled the formation of a (probably seasonal) pond. The "pond" is up to half a metre in depth, and the vegetation appears to consist of immersed terrestrial species such as grasses and buttercups. Habitat status: Ponds are UK and local BAP habitats. Habitat management: None apparent. Potential likelihood to support protected species: Great crested newts, possibly foraging bats. AWT Ecological Consultancy April 2010 44 University of the West of England AWT065 Extended Phase 1 Habitat Survey Target Note 21 Habitat Type: Ditch Plate 26: Northern section Plate 27: Southern section The majority of the length of the ditch was holding water at the time of survey, although the water was very shallow in some sections with excessive silting and no more than half a metre at the deepest point. Leaves were evident on the ditch bed. Water flow is in a northerly direction, with a culvert exiting the site at the northerly end. At the southern end is a pond (TN 17). Ditch vegetation is sparse, but there are extensive beds of water mint at points, and occasional hard and soft rush on the margins. Common reed occurs at the southern end and here a section of the ditch is lined with mature alder Alnus glutinosa trees. A small clump of frog spawn was found near the southern end, and mallard ducks were observed. Habitat status: Water bodies are a UK, Avon BAP habitat. Habitat management: The grass is cut to the edges of the water. Potential likelihood to support protected species: Great crested newts are unlikely, due to the presence of fish, but are possible, grass snakes.
