Grey long-eared bat surveillance 2012 2012


The grey long-eared bat (Plecotus austriacus) is considered to be one of the rarest bat species in the UK, with an estimated population of 1,000 individuals. In the UK its recorded distribution is largely confined to the extreme south of the British Isles. It may also be under-recorded due to the difficulty of separating it from the more common and widespread brown long-eared bat (P. auritus).

This study aims to improve our knowledge of the distribution of grey long-eared bat across its UK range through carrying out DNA analysis on droppings collected from long-eared bat roosts in target areas to provide verified identification to species level.
