A survey of Bailiwick bat species would have taken more than 45 years to complete without the help of hundreds of local volunteers, according to the States.

The now completed Bailiwick Bat Survey was a volunteer-led initiative organised by the British Trust for Ornithology (BTO), the States of Guernsey and Bailiwick La Sociétés and wildlife trusts.

Between 2021 and 2024, 420 volunteers collected more than 16 million bat sound recordings, which included six bat species never previously recorded in the Bailiwick.
