Bat Surveys

Bat SurveysShould a tree or building be suitable for use by bats, it will be necessary to undertake bat emergence surveys. These are undertaken at dusk/dawn by licensed bat ecologists from late April to mid-September when bats are active.

All survey work utilises a variety of recording techniques including heterodyne, time expansion and frequency division detectors and sonogram analysis where relevant. Should bats be found to be using the building/tree as a roost, then once planning permission is granted and prior to any work commencing, a European Protected Species Licence may have to be sought for a development affecting a European protected species.

All bat species are protected from deliberate killing, injury and disturbance and their roosts are protected from damage or destruction under Conservation of Habitats and Species Regulations 2010 and Section 9 of the Wildlife and Countryside Act 1981 (as amended).


Survey Reminders


This is a good time to carry out nut searches for signs of dormice. Late September is also the end of the reptile season and bat survey seasons. We start compiling the majority of European Protected Species licence (EPSL) applications from this time onwards.

Please refer to our survey timetable for further information on surveys that can be undertaken this season.
