Author: Newson, S.E., Else, R., Crymble, J., Gilbert, G., Tosh, D.G. & Booth Jones, K.A.
Published: 2023
Static acoustic bat detectors were deployed over a six-month winter survey season, to explore the possibility for using acoustics to detect and monitor the presence of Brown Rats on Rathlin Island in Northern Ireland. This report provides an overview of the survey coverage and main results from 2022/23.This research used the BTO Acoustic Pipeline to process and analyse sound recordings.
