Bat Surveys, Cumbria: Protected Species

What are bat surveys?

Bat surveys are undertaken for development sites to inform planning applications and determine presence of bats within a structure or tree. The local planning authorities will usually let you know which types of survey are 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 groups which are likely to be found in Cumbria. These include, common pipistrelle bat, Noctule bat, soprano pipistrelle bat, Daubentons’ bat, Whiskered bat, Brandt’s’ bat and Nathusius’ pipistrelle bat.

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.

Bat Surveys Cumbria: Types of Bat Survey


Preliminary Bat Roost Assessment: This is the first step in the bat surveying process which involves an ecologist carrying out a site visit. They will carry out an internal and external inspection of the building looking for evidence of bats, including insect feeding remains and bat droppings.

Nocturnal bat surveys: This involves ecology consultants using bat detectors to record and analyse bat calls. They will be either dusk emergence surveys (when bats are leaving their roosts to forage) or dawn re-entry surveys (the end of the night out when all the bats return back to their roosts).
