The bat survey season for activity surveys ends in mid-September. Nocturnal bat surveys involve surveyors observing a development site at dawn or dusk to watch for emerging or returning bats. The Bat Survey Guidelines recommend that surveys should be carried out between May and mid-September.
Our licensed bat specialists are able to undertake all aspects of bat survey including initial bat scoping surveys, dusk emergence and dawn re-entry flight activity surveys and remote monitoring. We have several years experience in the design and implementation of mitigation strategies including the construction of bespoke bat roosts, bat exclusions and roost enhancement, as well as applying for European Protected Species licences.
More information about bats and survey techniques can be found in our articles – Bat Droppings, the Bat-Year, Architectural Terms for Bat Surveyors, Guides to Bat Mitigation, Horseshoe Bat Mitigation and Brown Long-Eared Bat Mitigation.
