Dusk and pre-dawn emergence surveys of buildings and trees are used to find out how bats use a building. This allows us to develop a bespoke mitigation strategy and apply for a development licence.
Survey teams with bat detectors are deployed to observe a potential roost site at dusk or in the hours before dawn. We also use state of the art detectors that can be left at a site to monitor bat activity for weeks or months between surveys.
For some sites, observation in low-light with the naked eye is not enough, and we use infrared cameras with infrared spot lights to record bat’s behaviour.
