Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2017
Date Assessed: 2016-08-31
Assessor(s): Monadjem, A., Howell, K., Hutson, A.M., Mickleburgh, S. & Bergmans, W.
Reviewer(s): Piraccini, R.
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.

Geographic Range [top]

Range Description:This species is distributed in East Africa and marginally in Central Africa. It ranges from Ethiopia and southern Sudan in the north of its range, into Kenya, Uganda, eastern Democratic Republic of the Congo and Rwanda, to Tanzania and northern Malawi. It is largely, but not strictly, a montane species being found between 500 and 4,000 m Asl (with most records above 1,000 m).

Population [top]

Population:This appears to be a little recorded, but locally abundant species (Mickleburgh et al. 1991). It forms colonies of up to a few hundred bats.
Current Population Trend:Decreasing
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

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).
Generation Length (years):5

Threats [top]

Major Threat(s): 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.

Conservation Actions [top]

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.
