Bat Survey Leeds

Bat Survey

Bat surveys may be required for some developments to assist with planning applications to obtain planning permission for a development. Typically, the local planning authorities will let you know whether or not a bat survey is required A survey will help to determine whether there are bats located in a structure or tree within close proximity to the site.

These bat surveys detect the presence or likely absence of bats within the development area so that development plans can go ahead. If the survey finds that there are bats on, or within close proximity to a site, compensation and mitigation measures must be undertaken before any development work is permitted to proceed.

Bat Survey Leeds: Bat Activity


West Yorkshire bat activity is at it’s peak during the summer months. It is during this time of year that surveys should be carried out to determine the presence of roosting bats. If bat activity is found during a bat survey in the summer months, a bat hibernation survey could be required during the winter months to establish whether the area is also used by hibernating bats.

The many species of bat that are likely to be found in Leeds are Common pipistrelle bats, Noctule bats, Soprano pipistrelle bats, Whiskered bats, Daubentons’ bats, Nathusius’ pipistrelle bats and Brandt’s bats.

Bat Survey Leeds: Types of Bat Survey

There are two types of bat activity surveys. The first is a preliminary roost assessment which involves an Ecology Consultant carrying out a site visit. They will carry out both an internal and external inspection of the building looking for evidence of bat roosting, including insect feeding remains as well as bat droppings.

The second type are nocturnal bat emergence surveys which involves surveyors using bat detectors to record and analyse bat calls. These surveyors will operate either when bats are leaving their roosts to forage (dusk emergence surveys) or when the bats return to their roosts (dawn re-entry surveys).
