Habitat and Ecology
Most of the records of this species are from roosting caves in montane tropical moist forest, although it has also been recorded from a mosaic of East African evergreen bushland and secondary Acacia wooded grassland, with very few records from drier Guineo-Congolian rain forest, wet and dry miombo woodland, East African evergreen and semi-evergreen bushland and thicket, and deciduous bushland and thicket (Bergmans, 1994).

Reviewer/s
Hutson, A.M., Racey, P.A. (Chiroptera Red List Authority) & Cox, N. (Global Mammal Assessment Team)

Justification
Listed as Least Concern in view of its wide distribution, presumed large population, it occurs in a number of protected areas, and because the global population is unlikely to be declining fast enough to qualify for listing in a more threatened category.

Major Threats
The major threats to this species include ongoing deforestation in montane regions, likely disturbance of cave roosting sites (possibly from tourists in parts of its range), and possible overhunting of bats at roost sites for subsistence food by local people.

Management

Conservation Actions

Conservation Actions
Although there appear to be no direct conservation measures in place, it has been recorded from a number of protected areas (e.g.. Mount Elgon National Park, Kenya). There is a need to maintain remaining areas of suitable montane forest and to protect major roosting colonies from disturbance. In areas where this species is identified as being overhunted, there is a need to encourage the sustainable use of susceptible populations.
