During 2022, 622 different locations across the Bailiwick of Guernsey were surveyed. Recording was undertaken on 209 different nights mainly between April and the end of October, amounting to a total of 2,416 nights of recording effort across sites.
Overall, 3,389,138 recordings were collected which, following analyses and validation, were found to include 872,126 bat recordings, and 8,587 small terrestrial mammal recordings. Over 2 million recordings of bush-crickets and audible moth species were also recorded as ‘by-catch’, for which we report species presence on a site and night basis.
