Current Population Trend:Decreasing
Additional data:
Population severely fragmented:Yes

Habitat and Ecology [top]

Habitat and Ecology:It is a nocturnal species mostly confined to high altitude marshes within bamboo and montane forest. It is specialized for climbing on stems of marshy grass and other plants. The species has not been recorded from human habitats. Two pregnant females have been recorded with three embryos each, and a nest with four young has been found (Nowak 1999).
Continuing decline in area, extent and/or quality of habitat:Yes

Threats [top]

Major Threat(s): The small geographic range of the species has experienced considerable habitat destruction in recent years and has a very high human population density.

Conservation Actions [top]

Conservation Actions: The species is found in Kahuzi-Biega National Park in the Democratic Republic of the Congo, Kibira National Park in Burundi and in Mgahinga Gorilla National Park and Nyungwe National Park in Uganda. Research is needed into population numbers, the species range, biology, ecology, habitat status, threats, and potential conservation measures. Populations of this species should be monitored. Further management of the protected areas in which the species occurs is needed.
