Taxonomy [top]

Kingdom Phylum Class Order Family

Scientific Name: Achyranthes talbotii
Species Authority: Hutch. & Dalziel

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.
Reviewer(s): Hilton-Taylor, C. & Pollock, C.M. (Red List Programme Office)
This taxon was treated in Cable and Cheek (1998) as Endangered, being then recorded from only three sites, the type collection from Oban District, Nigeria and the Mt Cameroon collections on the Onge and Joke rivers. However, with the collections from Baseng in the Chide Valley and Nyandong in western Bakossi, together with the records of this taxon from two rivers in Littoral Province previously omitted, it is now known from seven locations and is therefore downgraded to Vulnerable. Loss of habitat is still a major threat to this species.
2000 Endangered

Population [top]

Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: The species occurs in fast-flowing rivers, growing half submerged and rooted amongst boulders; often around waterfalls, 0–750 m alt.
Systems: Terrestrial; Freshwater

Threats [top]

Major Threat(s): The proposed conversion of lowland forest around Mt Cameroon to plantation is likely to threaten the plant communities of the rivers that drain the area, such as the Onge, an important site for this taxon, through flooding and excessive silting of their habitat. Illegal logging for timber in lowland Bakossi is likely to have a similar impact.

Conservation Actions [top]

Conservation Actions: Botanical surveys of other suitable sites in S.W. and Littoral Provinces should reveal further populations of this taxon; monitoring of the riparian plant communities in response to increased upstream run-off should be carried out.
