Geographic Range [top]

Range Description: Nyctalus leisleri is largely a western Palaearctic species (Europe and north-west Africa), with scattered records in the western parts of the eastern Palaearctic (Pakistan, Afghanistan, the Himalayas). It is widely distributed in Europe from southern Scotland and Ireland more or less along southern edge of the Baltic Sea south and parts of Mediterranean coast to western Russia. It is present on Madeira and the Canary Islands (on Tenerife and La Palma only) but absent from southwestern Italy and Sicily, eastern Spain, most of Fennoscandia and northern Russia. In North Africa it is recorded from Mediterranean montane Morocco and Algeria and there is one record from Cyrenaica (Libya). It occurs from sea level to 2,400 m.

Population [top]

Population: It is widespread although patchily distributed in Europe. Common in parts of range (e.g., Ireland), scarce in other parts (Stebbings and Griffith 1986). Local extinctions have been reported for the central part of Russian Federation (K. Tsytsulina pers. comm. 2005), although the species remains common in other parts of Russia and the Caucasus (S. Kruskop pers. comm. 2005). In North Africa it is limited by the distribution of suitable habitat, but is particularly abundant in Djurdjura, NE Algeria. There is no information about trends.
Population Trend: Unknown

Habitat and Ecology [top]

Habitat and Ecology: It forages over woodland, pasture, and river valleys, where it feeds on flies (including mosquitos), moths and beetles. It is linked to old trees. Summer nursery roosts are located in tree holes, plus buildings and bat boxes. Nursery colonies usually number 20-50 females, occassionally up to 1,000 (e.g., in Ireland: Stebbings and Griffith 1986). In winter it hibernates mainly in tree holes, or occasionally in underground sites or buildings, often in large groups. Females migrate over distances up to 1,567 km (Ohlendorf et al. 2000).
Systems: Terrestrial

Threats [top]

Major Threat(s): Threats include disturbance to and destruction of roosts in trees and buildings, and loss or degradation of foraging habitat. However, these are not thought to be major threats at present.

Conservation Actions [top]

Conservation Actions: It is protected by national legislation in most range states. There are also international legal obligations for its protection through the Bonn Convention (Eurobats) and Bern Convention, in parts of its range where these apply. It is included in Annex IV of EU Habitats and Species Directive, and there is some habitat protection through Natura 2000. It occurs in protected areas throughout its range. No specific conservation actions known.
