Bat Surveys

All species of bats in England and Wales are listed as European Protected Species and as such require specialist surveys. These surveys range from assessments of trees and buildings for roosts (Preliminary Bat Surveys), through activity surveys, to emergence, netting and hibernation surveys. The level of survey required will be determined by what evidence is found of bats using a site and therefore whether a European Protected Species Licence will be necessary.

Preliminary bat surveys can be carried out at any time of the year, but all other surveys are seasonally dependent, the most important period being in summer, from late May to the end of August. European Protected Species licence applications take 30 working days to be determined, therefore it is important to take into account the seasonality of these surveys when planning a project to prevent delays to schedules.
