Scientific Name: Sclerochiton preussii
Species Authority: (Lindau) C.B.Clarke

Assessment Information [top]

Red List Category & Criteria: Endangered B2ab(v) ver 3.1
Year Published: 2014
Date Assessed: 2011-03-25
Assessor(s): Darbyshire, I.
Reviewer(s): Onana, J.-M.
Justification:
First collected 'near Buea' in Nov. 1891, it was rediscovered on Mt Cameroon 101 years later in the saddle of Mt Etinde-Mt Cameroon. It was subsequently found in the 1960s at Obudu, Nigeria. The Mt Kupe collections from the 1990s, from above Kupe Village and Nyasoso, represent a significant expansion in the area of occupancy, but it has not been recorded from elsewhere in Bakossi. The assessment of Endangered (since only three sites are known (area of occupancy of 16 km², extent of occurrence is 7,122 km²) and there is a continuing decline in mature individuals due to over-utilization) which was first made in Cable and Cheek (1998) and revalidated in Cheek et al. (2004), is maintained here since no new data are available.
History:
2004 Endangered
2000 Endangered

Population [top]

Population: The species is not at all common (very few collections) and thought to be declining because of over-use.
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: An understorey shrub of closed canopy submontane and montane forest; 1,100-1,400 m alt.
Systems: Terrestrial

Use and Trade [top]

Use and Trade: The stems are cut and used for trap "springing sticks" on Mt Kupe (M. Cheek pers. obs.).

Threats [top]

Major Threat(s): The stems are cut for trap "springing sticks" on Mt Kupe (Cheek pers. obs.); this is likely to have an impact upon the population of mature individuals at the two Kupe sites.

Conservation Actions [top]

Conservation Actions: As stated in Cable and Cheek (1998), an evaluation of the threat posed by exploitation of the species for making traps is recommended, and local trappers should be encouraged to use alternative, more common taxa. The species is supposedly in Mt Cameroon National Park and the Nigerian locality may also be in a protected area.
