Executive summary The local planning authority (Wychavon District Council) has requested a METHOD STATEMENT prior to demolition works at Rushwinds, Ombersley. An initial scoping survey, evening emergence and dawn re-entry / swarming survey was undertaken in August 2011 by Crawshaw Environmental and the survey was submitted with a planning application outlining the demolition of an existing house prior to the proposed rebuild. The initial survey effort identified the presence of one soprano pipistrelle and noted the significant potential of the property to support crevice-roosting bats. Subsequently, Wychavon District Council whilst satisfied with the original survey effort, requested additional information regarding mitigation and compensation following a response from Susanne Hiscock (Landscape and Natural Heritage Officer). Wychaven District Council has also requested a detailed Method Statement (July 2012) requiring a detailed working methodology with appropriate timing considerations to ensure that the proposed demolition works are carried out in such a way as to avoid or significantly reduce the impact of the operations on protected species. The attached method statement requires the work to be carried with due care and attention to the safe removal of all external materials where roosting or resting bats may be found; this requires removal of timber claddings, fascias and soffits by hand during the autumn period (September to October) as recommended by Natural England. Where there is a high risk of exposure of roosting bats it is normally ‘good practice’ to require the demolition works to be supervised by an ecologist / consultant; in this particular instance where there is only low to moderate risk of disturbing roosting bats it is recommended that only the removal of the dormers and the west gable-end cladding needs to be supervised. In all areas it is proposed that mitigation measures are followed as directed and the works proceed with due care and vigilance for the potential presence of roosting bats and / or accumulations of bat droppings. In the unlikely situation that roosting bats are exposed or likely to be disturbed, the standard caveats apply - ie. stop all work in that area of the building immediately, cover any exposed bats and seek further advice from a qualified person / consultant (or call the BCT helpline) before proceeding. D. Fisher (EED) 1 August 2012 Page 2 of 5 B introduction The proposed demolition of the building will require removal of external features such as timber cladding, fascia boards, soffits and roofing materials where there is a risk of exposing roosting bats. Although only a solitary bat was seen entering an area of the roof at the rear of the building, there remains a low to moderate risk of other solitary bats being exposed and disturbed during the proposed works. It is very unlikely however that the building has been used as nursery site, transitional roost or place of hibernation. A single bat species has been identified: Soprano pipistrelle (P. pygmaeus). The following methodology has been requested by the client (Mark Phillips) in response to a request from Wychavon District Council for a Method Statement prior to demolishing the building. It is important to note the following document has been prepared at short notice and therefore does not conform to the standard format for a NE Method Statement (WML A13.2). Revisions have subsequently been made following advice given by Suzanne Hiscock, Wychavon District Council on 14 September 2012. The following methodology is based on the Protected Species Survey (Project N. B1141) as submitted to Watson Stirrup Associates Ltd.on 24 April 2012 (Earthworks Environmental Design) in which detailed mitigation recommendations were given in addition to recommended compensatory works (NB. These recommendations are not repeated in the following document). METHOD STATEMENT: RUSHWINDS, Boreley lane, Ombersley Action: Method: Notes: 1. Timing of the works Works should not proceed before the beginning of September 2012 BMG p42 table 8.1 The majority of bat roosts within buildings are used on seasonally. Natural England advises optimum season / period for carrying out the works is 1 September to 1 May (allowing some variation between species. 2. Temporary bat box in situ It is recommended that a purpose built bat box is erected within the boundary of the site (on nearby trees) to house ant bats that may be accidentally disturbed or exposed during the works. It is important to note that any exposed bats should be carefully covered up preventing them to fly in daylight. In the event of a bat being found, contractors should avoid handling the bat and seek advice immediately. (refer to mitigation notes in previous document). 3. Removal of timber fascias and soffits / wall claddings All boards to be carefully removed by hand and lifted off carefully to avoid crushing resting bats; awareness at all times for the presence of accumulations of bat droppings, corpses or live bats. If any live bats are found, stop work in that area immediately and seek advice. Wall claddings and timber boarding, including removal of timber battens should be undertaken by hand also. Page 3 of 5 4. Removal of roof materials As above, all verge tiles and ridge tiles should be very carefully lifted by hand and roofing felts and battens lifted carefully to avoid crushing roosting bats. After removal check all working areas for the unexpected presence of exposed bats. NB. In very cool weather or after cold nights, resting bats mat be in a torpid state and therefore unable to move / or escape quickly. In an emergency, a torpid bat can move out of harms way but is unable to fly fo several minutes. 5. Removal of dormers These are likely to be higher risk structures and therefore additional care is required; roosting bats are most likely to occur between wavy-edge boards and the felt / battens beneath or between the window frames and the surrounding boards. The dormers should be removed under supervision by a licensed bat worker. Bats are also found beneath bitumastic felts and any roofing felt above these windows should be peeled of carefully in case bats are present. All dormer windows (front and rear) may be attractive to roosting bats. 6. West gable end - cladding The wavy-edge boards on the gable end wall are also higher risk and these should be removed by hand and lifted off singly to avoid crushing resting bats; it is also important to check the ground directly beneath the boards in case a torpid bat has been displaced and fallen to the ground. The cladding/wavy edge boards on the west gable-end should be removed under supervision by a licensed bat worker. 7. Removal of lead flashings As above, remove with care to prevent crushing / exposure. 8. Site Contractors. All site contractors must be made aware of the potential risk of exposing roosting bats at this site. The supervising ecologist shall give any contractors at the site instruction on how the removal of materials is best carried out. This shall be done by means of a tool box talk to contractors working on site. In addition a copy of the Method Statement should be made available to the demolition contractor in advance of ant work being carried out. 9. Compliance Although a development licence is not required in this case, the onus is with the developer to ensure that no offence will be committed if the development goes ahead. The existence of a method Statement helps to establish a defence against prosecution for intentional (WCA), deliberate (Habitat Regs.) or reckless (WCA) disturbance of bats or damage to roosts. A Method Statements is normally required by the local planning authority to ensure that procedures are in place before the development works are carried out. It is the responsibility of the LPA to ensure that the proposed works would not result in breaches of the Conservation (Habitat regs.) BMG, section 8.3 p.44. (WCA) Wildlife and Countryside Act. (Habitat Regs.) (Natural Habitats &c.) Regulations (1994) (as amended 2010). Page 4 of 5 C Summary The overall purpose of the Method Statement is to ensure that bats and their roosts are fully protected to ensure the ‘favourable conservation status of the species’. The Method statement is designed to minimise or remove any potential disturbance to roosting bats; appropriate timing of the works is very important. Works carried out in late summer and autumn will ensure that young bats are able to fly and forage independently and there is no risk to breeding bats or pregnant females / flightless pups. Autumn is an important time for bats as they prepare for winter hibernation and at this time of year bats and displaced bats can normally find alternative sites to roost and food is generally available.
