Thermal drone bat surveys use drone-mounted thermal imaging cameras to support the assessment of bat emergence and activity by providing an additional aerial perspective. Advances in thermal imaging, combined with automated analysis and rigorous human-in-the-loop interpretation, support robust and transparent assessment of bat emergence behaviour.

The approach is particularly suited to complex sites where roof structures, roof valleys, high elevations or recessed features are not readily visible from the ground. It can also be applied to smaller structures and trees, improving coverage of features, elevations and surrounding habitats where access or lines of sight are constrained.

Surveys may be undertaken alongside conventional emergence survey methods or, where justified by site context and survey objectives, as a standalone approach. 

All surveys are designed, supervised and interpreted by a bat-licensed, Chartered Ecologist, with careful consideration of disturbance, safety and relevant ecological and aviation requirements, in line with up-to-date best practice guidance for bat surveys.

Thermal imagery is processed using Wildlife Imaging Services movement-tracking software, followed by structured manual review to verify detections and interpret behaviour.

Outputs are provided as clear, quality-assured technical evidence to support ecological impact assessment, mitigation design and, where appropriate, bat mitigation licence applications. Technology is used to enhance survey coverage and confidence in interpretation, not to replace professional ecological judgement.
