Bat Survey, Wokingham: Protected Species Surveys

What is a Bat Survey?

Protected species surveys are required for some developments to assist with planning applications during the planning permission process to find out whether the development could impact bats and other protected species in the area. Typically, the local authority will let you know whether a bat survey is required in order for the work to be carried out. The need to undertake bat ecological surveys could also be identified during a PEA survey.

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

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

Types of Bat Survey, Wokingham

There are two types of bat surveys which can help you to discover whether signs of bats are present. The first ecological service, phase 1 of the bat survey is a preliminary bat roost assessment which involves an Ecology Consultant carrying out a site visit. The bat roost assessment will carry out both an internal and external inspection of the building, looking for evidence of roosting bats, including insect feeding remains as well as bat droppings.

The second type are nocturnal bat emergence surveys. Emergence and re-entry surveys 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.
