Taxonomy [top]

Kingdom Phylum Class Order Family

Scientific Name: Brachystephanus nimbae
Species Authority: Heine

Assessment Information [top]

Red List Category & Criteria: Vulnerable B2ab(iii) ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Assessor(s): Darbyshire, I.

First described from the Nimba Mountains in Upper Guinea, this species has a highly disjunct distribution on isolated mountain ranges across the Guinean phytochorion. The three collections from above Nyasoso on Mt Kupe represent a major increase in the extent of occurrence for this species; it has strangely not been found in other montane areas of Cameroon despite extensive collection in seemingly suitable sites. Threatened by habitat loss across much of its range.

Geographic Range [top]

Habitat and Ecology [top]

Habitat and Ecology: Found in mid-elevation forest, often in wet rocky areas, 900–1,100 m alt.
Systems: Terrestrial

Threats [top]

Major Threat(s): Forest clearance for agriculture at elevations less than 1,000 m represents a significant threat to the Cameroon population. The montane forests of Ghana and Ivory Coast are similarly threatened. Extensive forest remains on the Nimba Mountains.

Conservation Actions [top]

Conservation Actions: Survey of other likely sites in W. Africa, e.g., Mt Nlonako in W. Cameroon. Survey of current known populations may provide a greater understanding of its specific habitat requirements and so where it is most likely to be found in future.
