Bat Survey


Currently 18 species of bat are known to be present in the United Kingdom, 17 of these are known to be breeding and all a protected under the Conservation of Habitats and Species Regulations 2010 and the Wildlife and Countryside Act 1981 (as amended)*.


HalpinRobbins have licensed and experienced ecologists capable of conducting a range of bat surveys**, each tailored to meet our clients' needs and project requirements.

Bat surveys can be undertaken as "stand alone" surveys, part of Preliminary Ecological Appraisals or as part of Ecological and Environmental Impact Assessments and the requirement to undertake a bat survey is usually determined during a Phase 1 Survey. However if a site or project contains a watercourse, building, meadow, grassland, woodland, hedgerow, scrub, parkland, pasture or trees or is adjacent to such features it can be considered likely that a bat survey will be required in some form.

Each bat survey will start with a desk study and site walkover assessment to determine the potential for bats to be present. If this initial assessment concludes that there is a potential for bats then an active search will be undertaken. There are two general active search survey methods used for all 18 bat species within the United Kingdom, these are classed as field surveys and activity surveys.

Field surveys are a detailed inspection of a site looking for evidence of presence, such as feeding signs, droppings and staining, and activity surveys are a detailed assessment of the actual bat activity on site. The latter is usually undertaken through a combination of emergence and re-entry surveys or transect-walks using specialist equipment.

Although bats have complex behaviours and individual species requirements vary, all British bat species have broadly similar life-cycles and active seasons. To protect bats during periods of hibernation activity surveys are usually done between May to August, although building field surveys can be undertaken throughout the year.

HalpinRobbins are able to conduct habitat evaluations, bat activity and field surveys to assess the presence, absence and potential for bat species which can be used to inform decisions on land purchase, developments and project works, impact assessments and, where necessary, to obtain an appropriate wildlife licence.

Barn with Brown Long Eared Bats

 

*Protected under the Wildlife and Countryside Act 1981 (as amended) and the Conservation of Habitats and Species Regulations 2010 it is an offence to kill, injure or disturb a bat and to destroy any place it uses for rest or shelter.

** Bats are European Protected Species and all surveys must be undertaken by suitably experienced and wildlife licensed surveyor. Wildlife licences are issued by a relevant governing body (such as Natural England, Natural Resource Wales or Scottish Natural Heritage).

More information about all species of bat within the United Kingdom can be found at the Bat Conservation Trust.
