Red List Category & Criteria: Near Threatened ver 3.1

Although this species has a large range, it is generally rare, occurring in low density and numbers. It is mainly sedentary. The population is fragmented and linked to particular kinds of old forest habitats, which are declining. The species does not easily colonise new areas. Declines are widely reported in most of its range with a few exceptions in recent years. The status of this species is linked to forestry practices and the decline in the number of old trees (one colony may use up to 30 old trees with holes each summer season). Has specific habitat and diet requirements. Listed as Near Threatened (approaching A4c), as it is suspected that population declines will approach 30% over a 15 year period including both the past and the future.

Population [top]

Population:A rare or infrequent species. Summer colonies, usually c. 30. Winter clusters usually small (often solitary), but can reach 500 and, rarely, up to 1,000 in France, Poland and over 7,000 in Slovakia (Schober 2004). Extinct in the Netherlands since 1984. Last recorded in Norway in 1949, and possibly extinct there (van der Kooij in litt. 2006). Decreases widely reported. Considered threatened in many range states. Very small numbers in large part of the range with large temporary aggregations in areas without natural caves. Populations increasing in the last 5 years in Germany now that insecticide use has been reduced (D. Kock pers. comm. 2005). Relatively frequent in woodlands in western part of Caucasus and without reported decline; rare in Ukraine (S. Kruskop pers. comm. 2005). In Africa, population size and trends are unknown.
Current Population Trend:Decreasing
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:Forages in mature woodland, woodland edge (and agricultural edge). Feeds on small moths. Summer roosts: usually older mature woodland with maternity sites in trees (occasionally older buildings). Depends on a large number of old trees to roost in a large part of its range, because individuals change their roosts very frequently and colonies need a large number of roost sites for this reason. Winter: Hibernation may start in trees, but later underground sites are preferred. Usually in smaller numbers (up to 50) in natural caves, but in regions where these are missing in large groups in mines and bunkers. Underground habitats maybe of any type, but usually very cold sites. Recorded in old mines in winter in the Caucasus (K. Tsytsulina pers. comm. 2005). Movements up to 290 km in Austria (Kepka 1960).
Generation Length (years):5

Threats [top]

Major Threat(s): Loss of old mature woodland and ancient trees with loose bark or wood crevices (reforested areas are not suitable for this species); disturbance and loss of underground habitats, disturbance and loss of roost sites in older buildings. In Germany, habitat loss and fragmentation (caused by inter alia infrastructure development, forestry, and the renovation or demolition of old buildings used as roost sites), and disturbance (e.g. from cave tourism) are major threats (Schulenberg 2005); accidental mortality (roadkill) is also a problem (Rudolph et al. 2003).

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 where these apply. It is included in Annex II (and IV) of EU Habitats and Species Directive, and hence requires special measures for conservation including designation of Special Areas for Conservation. Some habitat protection through Natura 2000. Research is underway to establish conservation requirements for this species. Recommendations include adopting forestry practices that maintain old trees in sufficient numbers.
