Scientific Name: Schefflera mannii
Species Authority: (Hook.f.) Harms

Assessment Information [top]

Red List Category & Criteria: Vulnerable A2c ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Assessor(s): Cheek, M.
Reviewer(s): Hilton-Taylor, C. & Pollock, C.M. (Red List Programme Office)
Justification:
Forest clearance for agriculture and wood has reduced the habitat of this species by an estimated 30% or more over its whole range due principally to loss in the Bamenda Highlands, which, having the largest area above 2000 m in the Cameroon uplands, was probably once the stronghold for this species. Between 1987–1995, 25% of forest was lost in one area of the Bamenda Highlands (Moat in Cheek et al. 2000). Extensive losses of habitat have also occurred at Manenguba, Obudu, Bamboutos and Bafut-Ngemba.

Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: One of the very few montane (above 2,000 m alt.) trees that are endemic to the Cameroon uplands (another is Morella arborea), this evergreen canopy tree begins life as an epiphytic shrub. Found in montane forest; (1,400–)2,000–2,400 m.
Systems: Terrestrial

Threats [top]

Major Threat(s): Forest clearance for agriculture and wood are the main threats.

Conservation Actions [top]

Conservation Actions: The status of S. mannii on the Gulf of Guinea islands requires elucidation, perhaps by survey. At Mts Kupe, Cameroon and Mt Oku (Kilum-Ijim) the species seems secure currently.
