During 2023, 582 different locations across the Bailiwick of Guernsey were surveyed. Recording was undertaken on 228 different nights mainly between April and the end of October, amounting to a total of 2,260 nights of recording effort across sites.
Overall, 3,825,977 five second triggered recordings were collected which, following analyses and validation, were found to include 994,021 bat identifications, and 7,973 small terrestrial mammal identifications. There were also over 2 million identifications of bush-crickets as ‘by-catch’, for which we report species presence on a site and night basis.
