Occurrence and population status of the pond bat (Myotis dasycneme) in Northwest Russia

Abstract

Abstract Pond bat Myotis dasycneme is distributed from Belgium to Eastern Siberia, between 44°–50° N and 60° N. The total population of M. dasycneme is probably declining, but supporting data are incomplete. The conservation status of the species is not yet completely assessed. Surveys of hibernacula and foraging sites have been carried out recently in Northwest Russia. Evidence of a recent increase in numbers of wintering bats have been recorded, a northwards expansion is supposed. However, the local pond bat is still under threat as its most significant population is concentrated in only one hibernaculum, which is not well protected.
