There is a UK-wide network of over 90 volunteer based local bat groups working to protect and conserve Britain's bats. The Bat Conservation Trust can put you in contact with your local group where you can become active in protecting your local bat population.
Most groups organise training, especially for people who wish to become licensed as a bat worker.
Contact names and addresses for many Bat Groups are listed on this site. Please remember that the names given are often volunteers so please be considerate in the timing of your call. Registered Charity No. 1012361.
