Bailiwick Bat Survey 2022
The surveying season is now finished for 2022. We are currently analysing the data collected whilst our bats are hibernating. The 2022 report will be available next year.
The 2023 surveying season will begin again in spring. To receive updates or get involved in the survey, subscribe to our newsletter or send us an email – we’d love to hear from you!
The survey aims to improve our understanding of the distribution and activity of the different species of bat found in Guernsey, Herm, Alderney and Sark whilst providing an opportunity for anyone across the islands to take part in this project.
Why care about Bats?
Sadly, bat species around the world are vulnerable or endangered due to factors ranging from loss of habitat, diminished food supply, destruction of roosts, disease or killing of bats.
However … there are lots of things we can do to help!

2021 Bailiwick Bat Survey Report
During 2021, 720,011 recordings were collected across the Bailiwick of Guernsey which, following analyses and validation, included 710,260 bat recordings, and 8,211 small terrestrial mammal recordings. Over 1.5 million recordings contained bush-crickets and audible moth species which were recorded as ‘by-catch’, and we report species presence on a site and night basis.
The full report includes a full species-by species breakdown of spatial, seasonal and through-the-night patterns of activity.
