Application for a Licence

    Bats Method Statement

    Wildlife Licensing Unit The Method Statement will be used to determine the impact of the Natural England application on the favourable conservation status of the species concerned Burghill Road, (Regulation 53(9)(b)). Westbury-on-Trym Bristol BS10 6NJ You are strongly advised to refer to the Bat Mitigation Guidelines. T. 0845 601 4523 Please use photographs to support descriptions F. 0845 601 3438

    Document 1 - Background and Supporting Information

    The format below must be used and completed by a consultant ecologist or other suitably experienced person A Executive Summary. No more than one side of A4

    B Introduction

    B.1 Background to activity/development, include a brief summary of why the activity is necessary.

    B.2 Full details of proposed works on site that are to be covered by the licence e.g. barn/loft conversion

    to new dwelling, demolition of buildings, re-pointing of bridges and tunnels, lime kilns etc. Include current

    status of planning permission (if applicable).

    C Survey and site assessment

    C.1 Pre-existing information on the bat species at the survey site. Provide records from local

    environmental records centres, local bat groups, previous survey work by the applicant or others. C.2 Status of species at the local, county and regional levels.

    C.3 Objectives of the survey. e.g to determine presence/absence of bats, bat usage of site (e.g. maternity,

    hibernation, night roosts; foraging, commuting, swarming sites).

    C.4 Scaled plan/map of survey area of appropriate scale and orientation with integral or separate location

    map at 1:50,000 or 1:25,000 scale. Aerial photographs are also useful.

    C.5 Site/habitat description (relevant to bats), based on day-time visits (to include description of roost and

    habitat relevant to bat commuting/foraging behaviour). Include annotated photographs if helpful. C.6 Field survey(s). Include survey method (emergence counts, dawn surveys, site inspections), timings

    (day/evening), weather conditions (wind, rain, temperature tabulated for multiple survey visits), personnel

    involved (provide individual licence numbers, if held), and equipment used (type of bat detectors and

    logging equipment).

    C.7 Survey results. Summarise findings in table form (if appropriate); provide clear, annotated and cross-

    referenced maps/plans/photographs to show roost locations, flight lines, access points, dimensions of

    existing roosts etc.). Raw data to be appended, (including sonograms).

    C.8 Interpretation/evaluation of survey results (Bat Mitigation Guidelines section 5.8) Provide

    count/estimate of bat numbers, status of site (e.g. hibernation, maternity or feeding roost, swarming site

    etc), roost significance, constraints on survey (e.g. time of year, cold weather, access problems justify as

    necessary).

    D Impact assessment in absence of mitigation. See Bat Mitigation Guidelines (section 6.2)

    D.1 Short-term impacts: disturbance e.g. noise, vibration, dust, lighting, access obstruction due to

    scaffolding and plastic sheeting.

    D.2 Long-term impacts: roost modification e.g. new entrances (including human access e.g. for

    servicing/maintenance), change in size of roost space, changes in air flow etc., temperature and humidity.

    Note that impacts can be positive or negative as this is in absence of mitigation. WML-A13.2 (04/10) 1

    D.3 Long-term impacts: roost loss. Impact on different species populations to be taken into account at local,

    regional, and national level.

    D.4 Long-term impacts: fragmentation and isolation. e.g. loss of linear features such as hedges, tree lines,

    increased lighting, severance of flight lines by roads/rail lines.

    D.5 Post-development interference impacts. e.g. extra street lighting, use of loft space as storage. D.6 Predicted scale of impact on species status at the site, local county and regional levels.

    E Land ownership Mitigation site(s) (area(s) where any works will be done to offset development impacts, including development plot if applicable)

    E.1 Mitigation site ownership If the mitigation site is not owned by the applicant, you must provide the written

    consent of the relevant land owner(s). You must also provide details of how any measures to secure the

    population are to be maintained in the long term (e.g. a legal agreement). F References: List any references cited, and include credits for source information.

    G Annexes

    G.1 Pre-existing survey reports;

    G.2 Raw survey data.

Document 2 - Delivery Information

    The format below must be used and completed by a consultant ecologist or other suitably experienced person

    This document will be attached to the licence

    A Mitigation and compensation.

    A.1 Summary of mitigation strategy Overview of how the impacts will be addressed in order to ensure no

    detriment to the maintenance of the population at a favourable conservation status. To include a scaled

    map or plan that can be compared with the proposals on the survey results plan.

    B Works to be undertaken by the ecologist or suitably experienced person.

    B.1 Capture and exclusion (if applicable). Timings, effort, methods to be employed, care of bats, release sites

    etc. Include diagrams and photographs to show capture/exclusion apparatus. Include map to show location

    of capture and exclusion activities.

    C Works to be undertaken by the Developer/Landowner.

    C.1 Bat roosts

    C.1.1 In-situ retention of roost(s) providing details of all re-roofing works for example, replacement of

    tile type, replacement of felt with breathable membrane, use of insect guards, timber treatment; also

    include addition or changes in insulation and any impact on temperature/humidity. Explain how roost

    entrances will be retained and if purpose built entrances are required a scaled drawing of their

    design is required. Any enhancements to the roosts such as crevice provision should also be

    detailed. (include photographs)

    C.1.2 Modification of existing roost(s) dimension details, scale drawings of the roost and access points,

    orientation, state what services will be incorporated in the roost that might require regular servicing,

    for example, lift winding gear, electrical or plumbing services, gas boilers, partitioning of voids where

    a large property is being converted to a number of units, etc. (include photographs)

    C.1.3 New roost creation (including bat houses, cotes and bat boxes) dimension details including

    access points, location details, materials to be used e.g., timber, sarking felt, etc.. aspect, jstify

    variation from the original roost. Diagrams of widely available standard bat box designs are not

    required, just refer to bat box name and reference number, e.g., FF 1 Schwegler.

    C.1.4 Scaled maps/plans to show proposals/mitigation outlined above in relation to existing and proposed

    habitat features.

    D Post-development site safeguard

    D.1 Habitat/site management and maintenance to include details of what will be done in terms of habitat

    management and site maintenance required to ensure long-term security of affected population. Include

Use the notes column to provide any additional information or clarification, for example, if several activities are occurring within the same timeframe, explain the order in which they will take place.
