Bats in National Trust properties: a preliminary review

A preliminary analysis of the use by bats of National Trust properties revealed that all 14 resident species have been recorded. Comparison with a national database of records for Britain managed by English Nature (NCC Bat database) showed that the scarcer species are better represented roosting in buildings on Trust properties than in other buildings. In addition, survey of Trust properties has shown that a high proportion of buildings are used by bats. Bats provide unusual wildlife links between buildings, gardens and countryside through which the Trust can promote nature conservation, and resolve conflicts between building or landscape restoration and the bat habitat requirements. The role of the County Bat Groups in survey and promotion of bats on Trust properties is becoming increasingly important, especially if we are able to identify key properties for bats.
