Scientific Name: Myotis nattereri
Species Authority: (Kuhl, 1817)
Regional Assessments:
Common Name(s):
English Natterer's Bat
French Murin De Natterer
Spanish Murciélago Ratonero Gris
Myotis escalerae Cabrera, 1904
Taxonomic Notes: Does not include Myotis schaubi (Armenia and western Iran) and Myotis bombinus (southeastern Siberia, northeastern China, Korea, Japan). Two subspecies of M. nattereri are recognized: M. nattereri nattereri (N Africa, Europe, SW Asia Minor, Palestine) and M. n. tschuliensis (Caucasus region, Iraq, Turkmenia).

Part of the Iberian population has been described as a new cryptic species named Myotis escalerae (Ibañez et al. 2006), and recent genetic work indicates that true nattereri may not occur on the Iberian Peninsula, and that what occurs there is a third lineage which may have a broad range in southern Europe (12% genetic difference) (J. Juste pers. comm. 2007). However, for the purposes of this assessment escalerae is treated as part of nattereri.

Reviewer(s): Hutson, A.M., Racey, P.A. (Chiroptera Red List Authority) & Temple, H. (Global Mammal Assessment Team)
The species is widespread and abundant, and there is no evidence of current significant population decline. Consequently it is assessed as Least Concern.

Geographic Range [top]

Range Description: Myotis nattereri is a western Palaearctic species. It occurs in north-west Africa (coastal zone of Morocco and Algeria, extending inwards to western Atlas from sea level to 1200 m asl), and Europe from Portugal eastwards through the northern Mediterranean, and Ireland, southern Sweden and Finland into western Russia, Ukraine (including Crimea). Western and south-western Asia Minor, Levant, the Caucasus region (including northern Iraq), the Kopetdag Mountains in Turkmenia and Iran, northern Kazakhstan. Its altitudinal range is sea level to 2,000 m.

Population [top]

Population: In Europe it is widespread but never in large numbers. Colonies can reach 250-300 individuals in Jordan (Z. Amr 2000). In North Africa there are very few records, so populations are presumably small.
Current Population Trend: Stable
Additional data:
Population severely fragmented: No

Habitat and Ecology [top]

Habitat and Ecology: It forages in woodland (including Mediterranean pine and oak forest: Amr 2000), shrubland and parkland, sometimes over water, pasture, and road verges. It occurs in humid areas, and in dry areas it is dependant on water bodies. Summer roosts are in hollow trees, buildings and occasionally underground sites. It hibernates in underground habitats (caves, cellars and mines). It is a sedentary species, movements between summer, autumn and winter roosts are up to 120 km (Masing et al. 1999 in Hutterer et al. 2005).
Systems: Terrestrial

Threats [top]

Major Threat(s): No major threats. However, the species is affected by loss of woodland and other changes in land management and development. Loss of or damage to roost sites in trees, buildings and underground habitats may also be a problem. In the African part of the range, cave habitat where the species roosts is being destroyed by fires and vandalism. The species is collected for traditional medicinal purposes in North Africa.

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.

Protection of cave roost sites is required.
