1 SUMMARY

INTRODUCTION Kent Wildlife Trust is seeking to obtain planning permission for improvements to the existing visitor experience at its Sevenoaks Wildlife Reserve. The land subject to development proposals comprises a c.1.75 ha area located in the south-west of Sevenoaks Wildlife Reserve and Site of Special Scientific Interest (SSSI).

The site is dominated by bare ground with adjacent areas of semi-natural broadleaved woodland and dense scrub.

A Preliminary Ecological Appraisal undertaken by KWT Consultancy Services identified suitable habitat for reptiles within the site and a recommendation was made to evaluate the reptile populations known to be present within the SSSI using existing survey data for 2015-2019. This report summarises the findings of the existing reptile survey data and provides recommendations for mitigation and compensation.

RESULTS Sevenoaks Wildlife Reserve supports three common reptile species – slow-worms, grass snakes and viviparous lizards. Slow-worms and grass snakes have been recorded in the survey area closest to the site.

IMPACT ASSESSMENT The surveys focussed on areas of neutral/grassland scrub mosaic scattered throughout the Reserve. Within the site itself, limited areas of this habitat mosaic with numerous refugia features are located to the south of the Visitor Centre building. The garden of the Tadorna education building immediately to the north of the site also supports grassland/scrub mosaic and refugia features.

There are no areas of grassland/scrub mosaic within the north-east and centre of the site where the majority of groundworks will occur: the suitable habitat within these areas is limited to scattered bramble scrub and rubble piles associated with derelict buildings.

A Low-Good population of slow-worm (peak count 5 – 11 individuals) and Low populations of viviparous lizard and grass snake have been confirmed as present within the main reserve. The presence of three reptile species qualifies the reserve as a Key Reptile Site of County importance. The continuity of broadleaved woodland and scattered scrub habitats between the survey zones and site, together with the records of casual observations with the Tadorna garden, indicate that a Low population of viviparous lizard and grass snake, and a Low-Good population of slow-worm, is likely to be present within the site and its immediate surroundings.

The development proposals involve the demolition of five buildings and the removal of localised areas of scrub and trees in the north and east of the site to enlarge parking facilities and access routes into the reserve. Renovations will also be undertaken to the existing Visitor Centre building which will also involve localised scrub and tree clearance. The construction footprint is relatively small and much of it is on the edge of the main habitats used by reptiles. However, the vegetation clearance and construction phase of the road and parking areas and Visitor Centre renovations may lead to the accidental death of, or injury to, individual animals.

The proposals and potential impacts on reptiles are described below, with the location and extent of Areas 1, 2 and 3 shown on the map at Figure 5:

Area 1 – Approximately 105m2 of scattered scrub will be lost and 480m2 will be temporarily cut-back along the boundary of the southern construction area. Risk of the killing or injury of individuals of common reptile species during works.

Sevenoaks Wildlife Reserve. March 2021 Reptile Mitigation Strategy 1

KWT Consultancy Services

Area 2 – Approximately 180m2 of scattered scrub will be permanently lost within the Visitor Centre building construction area. Risk of the killing or injury of individuals of common reptile species during works.

Area 3 – Approximately 380m2 of scrub will be permanently lost through the creation of paths, roads and parking areas. Risk of the killing or injury of individuals of common reptile species during works.

Without mitigation, the above proposals would result in the temporary disturbance and/or killing or injury of individual reptiles from a population of County importance and the permanent loss of small areas of suitable habitat. All three reptile species present within the reserve are listed as Priority Species under Section 41 of the Natural Environment and Rural Communities Act (NERC, 2006). This equates to a Low-Negative impact level.

OUTLINE MITIGATION STRATEGY The constraints and proposed mitigation measures are described below and summarised in Table A. Exclusion Prior to the onset of groundworks, reptile fencing will be installed along the northern and eastern boundaries of the site to prevent entry / re-entry of reptiles into the works area from adjacent suitable habitat during the construction phase.

On completion of the construction period, the reptile exclusion fencing will be removed so that reptiles can return to the site.

Displacement of reptiles (Refer to Figure 5 in main report for location of areas described below) Area 1 – Small areas of scattered scrub around the edges of the works area will be cut in two stages, first cut to 300mm and second cut to a minimum of 150mm. A hand / destructive search of the area will then be undertaken. These areas will be maintained at a low sward height or as bare ground for the duration of the works. Reasonable Avoidance Measures (RAMs) will be followed –stored building materials will be raised on pallets, and all spoil/rubble or vegetation piles will be isolated within bare ground or short sward vegetation – away from adjacent areas of retained vegetation. Suitable storage areas for site works infrastructure, machinery and for any construction materials or proceeds from demolition and clearance need to be identified before site works commence.

Area 2 – Visitor Centre and Works Compound - Staged scrub removal and hand / destructive search of refugia will be carried out as for Area 1. RAMs will be followed to avoid animals moving into the stored materials from the lakeside and sensory garden area.

Retained areas of vegetation will be protected by the installation of Heras fencing around the construction works area.

Translocation Area 3 – A trapping program will be required to remove any reptiles present. Due to the limited suitability of the habitat within the site, the HGBI (1998) best practice guidance for translocations of Low populations of slow-worm, viviparous lizard and grass snake will be followed. Refugia (0.5m squares of roofing felt) will be placed throughout Area 3 at a density of 50/ha. The recommended minimum number of capture visits is 60 days – however, given the limited amount of suitable of habitat, particularly the lack of dense ground cover for slow-worm, an initial period of 15 visits will be carried out in optimal weather conditions for reptile activity (Froglife, 1999). Trapping in periods of prolonged wet or hot weather is considered unsuitable and site visits will not be carried out during such conditions.

Should no reptiles be recorded during the 15 day period then two-staged vegetation clearance will proceed within Area 3, followed by hand / destructive searches. Alternatively if reptiles are found during the initial 15 days, trapping will continue for a minimum of 30 days; captures will be plotted over time to monitor the expected downward trend until five consecutive days of zero capture have been achieved. Staged vegetation clearance and hand / destructive searches will then proceed as above. The land will then be released for development pending any other protected species mitigation required.

Animals captured during the trapping program will be released within a receptor area located at survey zone B in the north of the Reserve. This area supports suitable and well connected habitat but observations were consistently low throughout the 2015-19 survey period.

Timing All works to displace and trap reptiles will be carried out during the active season for reptiles i.e. March-October. Within all areas, the first cut of scrub to 300mm should be carried out during the period November-February, to avoid causing disturbance during the breeding bird season.

Compensation Prior to translocation, the receptor area will be enhanced for reptiles through the provision of hibernacula and log pile refugia (Appendix 3). Cordwood from felled trees within the site will also be used to create two large woodchip piles to provide egg-laying sites for grass snake and slow-worm.

On completion of construction, the site will be enhanced for reptiles through native shrub planting and the creation of log piles and woodchip piles from felled trees. In addition, a ‘gabion hibernacula’ will be constructed (using materials from the building demolition) as a low wall within the new development, adjacent to a south-facing bank and areas of dense scrub.

Monitoring Post construction monitoring is proposed for reptiles and should be undertaken during the first and third spring or autumn season after the development is complete. This will show whether reptiles are using the receptor area and the proposed development site, or whether any additional habitat management is required. The monitoring will comprise at least seven survey visits per year and can be undertaken as part of the long term monitoring of the wider reserve.

ECOLOGICAL ENHANCEMENTS In addition to the above measures, ecological enhancements should where possible be incorporated into the proposed development to contribute towards the objectives of planning legislation. In July 2018, the UK Government published the revised National Planning Policy Framework (NPPF) which states that “opportunities to incorporate biodiversity improvements in and around developments should be encouraged, especially where this can secure measurable net gains for biodiversity” (Para 175).

Enhancement recommendations for a range of habitats and species were provided within the PEA report. The following enhancements pertain specifically to reptiles:  Consider habitat management to create additional glades of neutral grassland/scrub mosaic to increase connectivity between existing areas.  Consider the creation of additional ponds which are not linked to the larger waterbodies, providing suitable habitat for amphibians and foraging grass snake.

2 INTRODUCTION

2.1 Background

Kent Wildlife Trust is seeking to obtain planning permission for improvements to the existing visitor experience at its Sevenoaks Wildlife Reserve. The land subject to development proposals comprises a c.1.75ha area located in the south-west of Sevenoaks Wildlife Reserve and Site of Special Scientific Interest (SSSI) – herein termed as ‘the site’.

The site is dominated by bare ground with adjacent areas of semi-natural broadleaved woodland and dense scrub. The central OS grid reference for the development area is TQ51942 56702.

The current proposals ae understood to include the following:  Demolition of five structures, several containers and limited areas of dense scrub and trees to facilitate new access and parking areas.  Removal of a limited area of trees and scrub in the vicinity of the existing visitor centre building and the enlarged parking areas and one way road system.  Extension and renovation of the existing visitor centre building.  Recladding and improved thermal performance of the visitor centre, requiring the temporary removal of all roof tiles and timber weatherboarding from all elevations.  Installation of air sourced heat pumps within the visitor centre and photo voltaic panels on the visitor centre roof.  Resurfacing of all access routes and parking areas.  New play area to east of visitor centre.  New areas of tree planting and soft-landscaping in the north, east and west of the site.

2.2 Scope of Work

KWT Consultancy Services was commissioned to undertake a Preliminary Ecological Appraisal (PEA) of the site in November 2019 (KWT CS, 2020). The PEA identified suitable habitat for reptiles within the site and a recommendation was made to evaluate the reptile populations known to be present within the SSSI using existing survey data for 2015- 2019. CIEEM suggests that surveys and reports that are between eighteen months and three years old may still be valid, dependent on the results of a walkover survey by an ecologist to determine the current status of the site compared with status of the site at the time of the original surveys.1 The site surveys undertaken as part of the PEA confirmed that there have been no significant changes to the site between 2015 and 2020 and no additional surveys were proposed.

KWT Consultancy Services were commissioned to undertake a desktop evaluation of the existing survey data. This report summarises the findings and provides recommendations for mitigation and compensation.

2.3 Survey Area

Sevenoaks Wildlife Reserve is situated on the northern periphery of Sevenoaks town (see Figure 1). The village of Dunton Green is located to the west, the A25 to the South, residential and commercial areas to the west and open agricultural land to the north. It is accessed from Bradbourne Vale Road at OS grid reference TQ5218 5636.

The Reserve is owned by Tarmac and leased / managed by Kent Wildlife Trust and comprises a 73ha area including five lakes and surrounding areas of broadleaved woodland with dense scrub, numerous smaller ponds, wet woodland and reedbed, with a number of bird hides and trails for public use. The river Darent flows through the north of the reserve. The Reserve is all designated as SSSI for its breeding wetland bird assemblage and Downy Emerald dragonfly. The reserve also sits in an area identified in the Sevenoaks District Plan as: Area of Archaeological Potential, and Metro Greenbelt.

The site subject to development proposals lies within the south-west corner of the Reserve; habitats within the site comprise amenity grassland, broadleaved woodland edge, scattered scrub and trees, and areas of unsurfaced bare ground and hard-standing. The site also includes the existing Jeffrey Harrison visitor centre building and an outdoor education/sensory garden area.

Figure 1 shows the extent of the Reserve and the general location of the site. Figure 2 shows the development proposals.

2.4 Objectives

The aims of the surveys and desktop evaluation were to:  determine the presence/likely absence of common reptile species within the Reserve.  determine the distribution of reptiles within the Reserve.  evaluate the relative size and importance of any reptile population within the Reserve.  suggest appropriate mitigation and compensation for reptiles with regard to the site and proposed development works.

3 LEGISLATIVE AND PLANNING POLICY FRAMEWORK

All British reptiles are afforded legal protection under Schedule 5 of the Wildlife and Countryside Act 1981 (as amended) largely as a consequence of a national decline in numbers due to habitat loss. Under the terms of the Act, it is an offence to intentionally kill or injure a reptile and accordingly in order to avoid committing an offence under the Act, appropriate mitigation techniques need to be incorporated for reptiles occurring within development sites. Mitigation methods for reptiles may include trapping and relocation of animals to a suitable receptor site, combined with the exclusion of the development site through the use of reptile fencing. Measures to enhance habitats for reptiles include the provision of hibernacula and appropriate management to improve foraging areas may also be required.

Mitigation for the more common British reptiles and amphibians does not require a licence from Natural England but would typically be agreed in consultation with the local planning authority.

4 METHODOLOGY

4.1 Desktop Study

A search for local records of reptiles was requested from the Kent and Medway Biological Records Centre as part of the wider Sevenoaks Wildlife Reserve Preliminary Ecological Appraisal (Enquiry No: 19/537) (Kent Wildlife Trust, 2020); the results are reproduced within this report.

4.2 Reptile Presence / Likely Absence Surveys

Reptile surveys across the Reserve were carried out by KWT site staff and volunteers for the five year period 2015-2019. The surveys were focussed within six areas of the Reserve identified as comprising suitable habitat for supporting reptiles such as neutral grassland and scrub mosaics. These areas varied in size from path-side verge areas to wider glades, and were bordered by broadleaved mixed woodland and heathland habitats. They are linked to the proposed development site via corridors of mixed broadleaved woodland and scattered scrub; areas of grassland/scrub mosaic within these corridors are limited to occasional small (c.5m2) lakeside fishing spots. The six zones are shown labelled as A – F on the map included at Figure 3.

A total of 60 artificial refugia were placed in areas of suitable habitat within zones A – F in 2015 and have remained in-situ to the present time. The refugia comprised 0.5m x 0.5m squares of roofing felt (35 squares), corrugated tin (20 squares) and carpet tiles (5 squares). All artificial refugia were surveyed on a weekly basis between March and October 2015- 2018, and between March and July 2019. In addition to these targeted surveys records have also been kept of casual observations.

Although the site is 73ha in size, approximately 39ha of this comprises open water. Accordingly, the density of artificial refugia either met, or exceeded, the recommended minimum density of ten refugia per hectare of suitable habitat (Froglife, 1999).

Table 1 shows the size and refugia density for each zone. Table 2a includes details of the broad habitat types present within each survey zone and Table 2b shows the distances separating each survey zone from the site.

4.3 Surveying / Weather Conditions

To establish presence, the Froglife (1999) guidance recommends that a minimum of seven survey visits under favourable weather conditions are required, and the English Nature advice within the Species Conservation Handbook (1994 et seq.) states that ‘it is difficult to get any reliable opinion of animals in a population in less than 5 to 10 visits’. Over the five year survey period, a total of 131 survey visits were undertaken within each survey zone.

Froglife also advises that in relation to time of year, “Reptiles are generally active from March to October, but the most profitable months for surveying tend to be April, May and September. The exact timing however will depend on temperature, rainfall and other climatic patterns.” Suitable weather conditions as detailed by Froglife (1999) specify survey temperatures between 9C and 18C, with no wind or rain, and, depending on conditions, between the hours of 08:30 and 11:00 hours or 16:00 and 18:30. However, it is recognised that peak counts of reptiles can often occur outside of these times and the surveys were timed to utilise the best available weather conditions.

The majority of the surveys were undertaken in accordance with the suitable weather conditions described above. Due to the long term, weekly nature of the monitoring program, a low number of surveys were undertaken in sub-optimal conditions, i.e. temperatures outside of the recommended range or light rainfall. Table 3 provides details of the number of surveys carried out under optimal / sub-optimal conditions. Full weather data for each survey date is provided in Appendix 2.

* in 2015 only air temperature data is available

4.4 Evaluation Methodology

Due to the variability in the number of animals (i.e. proportion of a population) seen during reptile survey visits, for example due to variation in weather and behavioural patterns, it is not possible to estimate the size of reptile populations on the basis of presence/likely absence survey results. Froglife (1999) suggests that a ‘basic evaluation of the size and importance of reptile sites’ can be obtained using the scoring system for Key Reptile Sites, reproduced in Table 4 below. The results of the surveys and the criteria detailed within the table were used to assess the reptile populations within the Reserve.

The scoring system is based on peak adult counts observed under artificial refugia placed at a density of up to 10 per hectare, and/or by general observation by one person, in one day. Hatchlings, juveniles and sub-adults are excluded from the assessment.

Table 4. Criteria for the assessment of Key Reptile Sites (after Froglife, 1999).

4.5 Limitations

The survey data has been obtained from long term monitoring of reptiles within the wider Reserve and the surveys did not include the less suitable habitats within the proposed development site. The habitats within the Reserve – comprising broadleaved woodland, scrub and unmanaged grassland – are considered to be of greater suitability for reptiles than those within the proposed development site, and areas close to the proposed development site were surveyed; it is therefore considered that the species and relative density of reptiles observed within the wider reserve represent a reliable indication of the maximum number of species and individuals which are likely to occur within the site.

There is some discrepancy between the methodology of best practice guidance with regard to refugia tile density and weather conditions (Froglife, 1999). However, the density of refugia within all survey zones was either equal to or higher than that recommended by Froglife (1999) and the majority of surveys were undertaken in line with optimum temperature conditions. Furthermore, many observations of reptiles were still recorded during visits in sub-optimal conditions, and the total number of visits undertaken is significantly greater than the minimum number recommended by Froglife (1999). The survey data is therefore considered to provide a thorough and reliable indication of the reptile species present within the wider reserve.

5 RESULTS

5.1 Desktop Records

The KMBRC data search (Enquiry No: 19/537) has records dating from 2017 of viviparous lizard Zootoca vivipara, slow-worm Anguis fragilis, and grass snake Natrix helvetica from the Reserve. There are also two records of adder Vipera berus from the Reserve, the most recent dating from 2002. It is also known that the Reserve was used as a translocation area for slow-worms in 2009 (Kent Wildlife Trust, 2013).

5.2 Survey Data

Slow-worms, grass snakes and viviparous lizards were recorded during the surveys. Tables 5 – 9 show the total number of observations (not individuals) recorded per month for years 2015-2019 for each survey zone. The full survey data is provided in Appendix 2.

The data in Tables 5-9 has been summed for each month and refers to total observations rather than total individuals recorded. The relative abundance of each species within the Reserve as a whole and within each survey zone can be inferred by differences in the number of observations made as follows:  In all years, the majority of observations for all species were made in zones C and F. These areas are located 1.2km and 523m to the east of the site, respectively. The nearest survey zone to the proposed development site is zone A – slow-worm was the only species recorded within zone A in 2018, and grass snake was the only species recorded in zone A in 2019.  The most frequently recorded species was slow-worm – the highest number of monthly observations of slow-worm was recorded in 2016, when 34 observations were recorded during June. Within zone A, a maximum of three observations of adult slow-worm were made within any one month (June 2018); within zone F, the highest number of observations was 22, recorded in both July 2015 and August 2018. In 2019, the highest number of observations of adult slow-worm made within zones A and F in any one month, were nil and 13 respectively.  The highest number of monthly observations for viviparous lizard was recorded in October 2017 (9 individuals). The highest number of observations for adult common lizard in zone A was nil. The highest number of observations within any one month in zone F was five, recorded in April 2018. In 2019, the highest number of observations of adult common lizard made within zones A and F, in any one month, were nil and three respectively.  The highest number of observations of grass snake was recorded in 2018 – 16 observations were made during July 2018. The highest number of observations for adult grass snake in zone A was two, in May 2015. The highest number of observations in zone

KWT Consultancy Services

F was 16, in July 2018. In 2019, the highest number of observations of adult grass snake made within zones A and F, in any one month, were one and eight respectively.  Juveniles and sub-adults of slow worm and grass snake were frequently recorded, confirming successful breeding by these species.

In addition to the data above, casual observations of grass snake and slow-worm have been made within the vicinity of the ‘Tadorna’ education building, lying immediately beyond the site’s northern boundary (Celia Davies (KWT), pers. comm.).

5.3 Evaluation of Survey Results

The full survey data (Appendix 2) for April – June were used to determine the peak count of individuals on any one survey date for each reptile species during 2018 and 2019. April and May are generally two of the most profitable months for surveying reptiles (Froglife, 1999) and June also yielded consistently high rates of observation during the surveys at the reserve. Records from each date across all survey zones were summed due to the good habitat connectivity across the reserve (Table 10).

5.3.1 Key Reptile Site Evaluation

The data within Table 10 shows that the Reserve supported a ‘Good’ population of slow- worm and ‘Low’ populations of grass snake and viviparous lizard during both 2018 and 2019.

Due to variation between survey zones in terms of the amount of suitable grassland/scrub mosaic, the density of refugia varied between 10-25 per hectare. Within the two zones which yielded the highest observation rate - C and F - the refugia density was 16-20/ha. As such, the population sizes within the reserve may be lower than indicated in Table 10.

The wider reserve supports three species of reptile and thereby qualifies as a Key Reptile Site under the first criteria (Table 4).

6 IMPACT ASSESSMENT

The surveys focussed on areas of neutral/grassland scrub mosaic scattered throughout the Reserve. Within the site itself, limited areas of this habitat mosaic with numerous refugia features are located to the south of the Visitor Centre building. The garden of the Tadorna education building immediately to the north of the site also supports grassland/scrub mosaic and refugia features.

A Good population of slow-worm and Low populations of viviparous lizard and grass snake have been confirmed as present within the main reserve. The presence of three reptile species qualifies the reserve as a Key Reptile Site of County importance. The continuity of broadleaved woodland and scattered scrub habitats between the survey zones and site, together with the records of casual observations with the Tadorna garden, indicate that a Low population of viviparous lizard and grass snake, and a Low-Good population of slow-worm, is likely to be present within the site and its immediate surroundings.

The development proposals involve the demolition of five buildings and the removal of localised areas of scrub and trees in the north, south and east of the site to enlarge parking facilities and access routes into the reserve. Renovations will also be undertaken to the existing Visitor Centre building which will also involve localised scrub and tree clearance. The construction footprint is relatively small and much of it is on the edge of the main habitats used by reptiles. However, the vegetation clearance and construction phase of the road and parking areas and Visitor Centre renovations may lead to the accidental death of, or injury to, individual animals. Figure 2 shows the proposals for the site.

The proposals and potential impacts on reptiles are described below, with the location and extent of Areas 1, 2 and 3 shown on the map at Figure 5:

7 RECOMMENDATIONS

The proposed development works will lead to the permanent loss of 665m2 and the temporary loss of 480m2 scattered scrub and grassland mosaic habitats which support individuals of slow-worm, grass snake and viviparous lizard.

Natural England’s (NE) Standing Advice for reptiles2 includes the following guidance on mitigation planning to landowners and ecologists:  Consider changing the layout and not developing the areas used by reptiles;  Displace reptiles from sensitive areas by changing the vegetation;  Time works sensitively, and/or  Move the reptiles (translocate) to another area that has been specially prepared, but only as a last resort, and maintain connectivity.

As part of compensation for the loss of reptile habitat, NE’s Standing Advice includes the following recommendations:  Creating links to other habitats;  Creating new habitat, and/or  Improving existing habitat.

7.1 Outline Mitigation Strategy

The mitigation proposals for the site are described below. Mitigation areas are shown in Figure 5.

Exclusion Prior to the onset of groundworks, reptile fencing will be installed along the northern and eastern boundaries of the site to prevent entry / re-entry of reptiles into the works area from adjacent suitable habitat during the construction phase.

On completion of the construction period, the reptile exclusion fencing will be removed so that reptiles can return to the site.

Displacement of reptiles Area 1 – Small areas of scattered scrub around the edges of the works area will be cut in two stages, first cut to 300mm and second cut to a minimum of 150mm. A thorough hand search of the area will then be undertaken followed by a final cut to <50mm. These areas will be maintained at a low sward height for the duration of the works. Reasonable Avoidance Measures (RAMs) will be followed –stored building materials will be raised on pallets, and all spoil/rubble or vegetation piles will be isolated within bare ground or short sward vegetation – away from adjacent areas of retained vegetation. Suitable storage areas for site works infrastructure, machinery and for any construction materials or proceeds from demolition and clearance need to be identified before site works commence.

Area 2 – Visitor Centre and Works Compound - Staged scrub removal and hand searches of refugia will be carried out as for Area 1. RAMs will be followed to avoid animals moving into the stored materials from the lakeside and sensory garden area.

Retained areas of vegetation will be protected by the installation of heras fencing around the construction works area.

Translocation Area 3 – A trapping program will be required to remove any reptiles present. Due to the limited suitability of the habitat within the site, the HGBI (1998) best practice guidance for translocations of Low populations of slow-worm, viviparous lizard and grass snake will be followed. Refugia (0.5m squares of roofing felt) will be placed throughout Area 3 at a density of 50/ha. The recommended minimum number of capture visits is 60 days – however, given the limited amount of suitable of habitat, particularly the lack of dense ground cover for slow- worm, an initial period of 15 visits will be carried out in optimal weather conditions for reptile activity (Froglife, 1999). Trapping in periods of prolonged wet or hot weather is considered unsuitable and site visits will not be carried out during such conditions.

Should no reptiles be recorded during the 15-day period then two-staged vegetation clearance will proceed within Area A, followed by hand / destructive searches. Alternatively, if reptiles are found during the initial 15 days, trapping will continue for a minimum of 30 days; captures will be plotted over time to monitor the expected downward trend until five consecutive days of zero capture have been achieved. Staged vegetation clearance and hand searches will then proceed as above. The land will then be released for development pending any other protected species mitigation required.

Animals captured during the trapping program will be released within a receptor area located within survey zone B in the north of the Reserve. This area supports suitable and well connected habitat for reptiles and observations were consistently low throughout the 2015-19 survey period.

Timing All works to displace and trap reptiles will be carried out during the active season for reptiles i.e. March to October, and also in accordance with timings required for Roman Snail mitigation within the same habitat areas. Within all three areas, where scrub has potential to support nesting birds the first cut of scrub to 300mm should be carried out during the period November-February, to avoid causing disturbance during the breeding bird season. Compensation Prior to translocation, the receptor area will be enhanced for reptiles through the provision of hibernacula and log pile refugia (Appendix 3). Cordwood from felled trees within the site will also be used to create two large woodchip piles to provide egg-laying sites for grass snake and slow-worm.

Monitoring Post construction monitoring is proposed for reptiles and should be undertaken during the first and third spring or autumn season after the development is complete. This will show whether reptiles are using the Receptor Area and the proposed development site, or whether any additional habitat management is required. The monitoring will comprise at least seven survey visits per year and can be undertaken as part of the long term monitoring of the wider reserve.

8 ECOLOGICAL ENHANCEMENTS

In addition to the above measures, ecological enhancements should where possible be incorporated into the proposed development to contribute towards the objectives of planning legislation. In July 2018, the UK Government published the revised National Planning Policy Framework (NPPF) which states that “opportunities to incorporate biodiversity improvements in and around developments should be encouraged, especially where this can secure measurable net gains for biodiversity” (Para 175).

Appendix 4. Example Specification for Temporary Reptile Fencing using Recycled / Re-useable materials

Fitted measurements:-

Installed 300mm vertically below ground, 375mm vertically above ground

Fitting/installation Description

The fencing panels are fitted into a 300mm deep × 50mm slit trench using handheld machinery.

Once the newt fencing panels are positioned (fitted to the side of the trench nearest to the relevant population or the inside if a containment area and ‘overlapped’ by 50mm), the slit is closed up and compacted using handheld machinery. This creates a total seal between the soil and the newt fencing panels. The newt fencing panels are then secured by aluminium blind rivets along the overlap joint. Fencing panels can be cut down or the overlap increased to allow for uneven ground or contours.
