Habitat and Ecology [top]

Habitat and Ecology:This species is associated with both montane and lowland tropical moist forest. The Guinea specimens were captured in a secondary forest close to primary forest, while the Liberian specimen was captured in upland "undisturbed High Forest" (Fahr et al. 2002). The day roosts of this species are not known, although it is suspected to roost as small colonies in caves, mine shafts and similar habitats (Fahr et al. 2002).

Threats [top]

Major Threat(s): The species is threatened by deforestation of its habitat, largely through logging and mining operations, and conversion of land to agricultural use. It is also considered possible that the species could be threatened by overharvesting for subsistence food in the future.

Conservation Actions [top]

Conservation Actions: It is not known if the species is present in any protected areas. There is a need to protect suitable areas of forest habitat for this species, and to initiate appropriate bat conservation awareness programmes among local people. In addition, further studies are needed into the distribution, abundance, natural history, and threats to this species.
