Bat Survey, Buckinghamshire: Protected Species Surveys

Bat surveys are undertaken for development sites to inform a planning application and determine the presence of bats within a structure or tree and how it may affect bats in the area. The local authorities at a record centre will usually let you know if a bat survey is required.

A bat survey will detect the presence or likely absence of bats in a particular area so that plans can be made to proceed with a development. If bats are found to be present on a site, mitigation and compensation measures must be undertaken before any development work can begin.

There are many species of bat which are likely to be found in Buckinghamshire. These include common pipistrelle bat, Noctule bat, soprano pipistrelle bat, Daubentons’ bat, Whiskered bat, Brandt’s bat and Nathusius’ pipistrelle bat.

In Buckinghamshire, bat activity is highest during the summer months. Therefore, surveys should be carried out during this time to determine the presence of roosting bats. If bat activity is found during a bat survey in the summer months, a bat hibernation survey may be required during the winter to establish whether the area is also used by hibernating bats.
