Specialist Bat Surveys

Surveys and research into Irish bats has been at the heart of Scott Cawley’s ecological expertise for the last ten years. As a result we are one of Ireland’s most experienced and equipped teams to be able to carry out a range of bat surveys and it forms a core part of our business. These range from presence/absence surveys for buildings, bridges and trees to more complex flight path and foraging resource studies using the latest telemetry, remote sensing  and night vision techniques.

All Scott Cawley ecologists are licenced to carry to surveys that may disturb bats and selected staff are also licences to capture and handle bats under specific circumstances.
