Forestry England Passive Acoustic Bat Survey

The Forestry England Passive Acoustic Bat Survey collects data from a number of Foresty England sites. Within each site static acoustic sensors (AudioMoths) are deployed at a random stratified sample of monitoring locations, and used to record bat activity over several nights from July - September. Recordings are intially classified to species using the BatDetect2 algorithm. After automatic classification, all records apart from those of Pipistrellus pipistrellus, Pipistrellus pygmaeus and the Myotis species group are manually verified from spectrograms of the recordings. These surveys are funded by Forestry England and coordinated by the Bat Conservation Trust.
