Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): Dieterlen, F. & Kerbis Peterhans, J.
Reviewer(s): Amori, G. (Small Nonvolant Mammal Red List Authority) & Cox, N. (Global Mammal Assessment Team)
Listed as Vulnerable because its extent of occurrence is less than 20,000 km², its distribution is severely fragmented, and there is continuing decline in the extent and quality of its habitat in the Albertine Rift.

Population [top]

Population:In some swamps it may be common but to date only about 20 specimens have ever been collected.
Current Population Trend:Decreasing
Additional data:
Population severely fragmented:No

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).
Systems:Terrestrial; Freshwater

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. However, much of the species habitat is in the highlands which is well protected in the Kahuzi-Biega National Park (Democratic Republic of the Congo), the lowlands are more threatened.

Conservation Actions [top]

Conservation Actions: Most of the specimens were collected in Kahuzi-Biega National Park in the Democratic Republic of the Congo. 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.
