UK Bats

Brown long-eared bat in gloved handWe are lucky enough to have 18 species of bat in the UK, 17 of which are known to be breeding here - that's almost a quarter of our mammal species.

Every summer, thousands of people venture out to experience the wonder of bats in their natural environment. Sadly, bat populations have suffered severe declines during the past century, but the Bat Conservation Trust and more than 100 local bat groups are working hard to help our bats hang on. Learn more about where to see bats!
