The descriptive text, below the map, is from the Cornish Red Data Book (2009). The map on this web page depicts the organisms distribution and shows the records made pre-2000 and those made since.
Range & Status
Mainly found from Western Europe to Asia Minor (Corbet & Harris, 1991; Strelkov, 1997a; Mitchell-Jones et al. , 1999). Widespread but rare in Britain. Previously considered to be a vagrant or migrant. Now known to have seven nursery sites with roosts (of all sorts) found throughout the UK.
Records since 2000 are for the Penzance, The Lizard and Penryn areas but it is possible that the species is basically under-recorded. The number of 1km squares in which it is recorded has increased from two to four.
Habitat & Ecology
Parkland and mixed light woodland. Uses holes in trees and crevices and buildings both summer and winter.
See Introduction. Disturbance in roosts.
Extensive legal protection detailed in Introduction. At low risk of extinction worldwide
(IUCN status, 2001).
