Bat emergence survey season is fastly approaching. Our team has limited slots available.
Did you know?
If evidence of bats is found in a building during a preliminary roost assessment (PRA) or there is potential for bats to be present in unseen locations, e.g., above wall tops or under ridge tiles, bat emergence surveys are required to give confidence to a negative assessment or categorise any roost, in accordance with bat survey guidelines (Collins 2023).
Bat emergence surveys can only be undertaken during the active survey season from May – September, although the optimal time is from May to August and spaced out by at least three weeks.
In addition to the above, we also have the expertise to conduct ground level tree assessments (GLTA), aerial tree inspections (ATI) and see a project through the licencing process (when required).
Get in touch to book in your required surveys before it’s too late.
Bonus image – These three brown long-eared bats were identified using a dilapidated barn building as a feeding roost, which required subsequent licencing to keep the project moving.
Survey reports and mitigation plans are required for development projects that could affect protected species, as part of obtaining planning permission. They need to show whether protected species are present in the area or nearby, and how they use the site along with mitigation plans of how this will be avoided, reduced or managed any negative effects to the protected species. A licence will be required from Natural England if damaging their habitats can’t be avoided.
