Bat Survey, Cardiff

What is a Bat Survey?

Bat activity surveys may be required for some developments to assist with planning applications during the planning process to find out whether the plans could impact bats in the area. Typically, the local planning authority will let you know whether or not a bat ecology survey is required. The need for different types of ecology surveys could be identified during a PEA survey.

Bat surveys detect when a bat is present within the development area so that the planning process can proceed. If the survey finds that there is evidence of bats in close proximity to a site, bat mitigation and compensation measures must be undertaken before any development work is permitted to proceed.

These measures are required as bats, and bat roosts within trees, are protected species under the Wildlife and countryside Act, and they are also a European protected species. Therefore, it is illegal to kill, harm or disturb bats in any way.

Collington Winter regularly undertake bat surveys for development projects based in South Wales, including Cardiff, Swansea and Neath Port Talbot.

Types of Bat Survey, Cardiff

The first type 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, following the method statement, to look for evidence of roosting bats.

The second type are nocturnal bat emergence surveys which involve 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) to determine the number of bats.
