BTHK comprises descriptions and accounts of how Potential Roost Features (PRF) form in trees and how bat species native to the British Isles use them. It includes accounts from the front-line of some of the rarest species provided by professional bat-workers and committed amateurs alike. Anyone can contribute as the text is updated annually. Bat Conservation Trust has recently taken over the Bat Tree Habitat Key Project from Henry Andrews. We are very grateful to Henry for all of his hard work and for trusting that we are the right organisation to take the project forwards. We are currently working through a few changes and discussing how best to develop the project for the future so please bear with us. BCT is not regularly monitoring this page, we are only adding new records after they have been processed. Please note that members are not able to post information, only to comment on our posts.
