Assessment Information [top]

Red List Category & Criteria: Vulnerable A2c ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Assessor(s): Darbyshire, I.
Reviewer(s): Hilton-Taylor, C. & Pollock, C.M. (Red List Programme Office)
Justification:
A highly distinctive species known from just 12 locations. Populations appear disjunct, being absent in several seemingly suitable areas. In Bakossi, it is only known in the west, though further exploration of the lowlands of southern Bakossi may reveal further populations. It is also absent from the lowlands around Mt Cameroon, and has not been recorded in extensively collected forest areas around Bipinde and Kribi in South Province, Cameroon.

Population [top]

Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: Lowland forest, often along streams, 0–700 m alt.
Systems: Terrestrial

Threats [top]

Major Threat(s): Throughout its range, deforestation has been extensive in the lowlands, and this continues outside protected areas.

Conservation Actions [top]

Conservation Actions: As the species is readily identifiable, population census data should be possible in protected areas, and an assessment of its habitat requirements made. Further inventory work in suitable lowland sites, such as the Loum Forest Reserve, may provide additional sites.
