Assessment Information [top]

Red List Category & Criteria: Vulnerable A2c; B2ab(iii) ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Assessor(s): Pollard, B.J. & Darbyshire, I.
Reviewer(s): Zapfack, L. & Cribb, P.J. (Orchid Red List Authority)
Justification:
The Nigerian locations are threatened by continued extensive clearance of forest to high elevations; one or more of these subpopulations are likely lost. The plant at Enyandong, Cameroon was found growing in largely cleared forest, on a tree in the village. It is therefore likely to occur in the surrounding forest, some of which is being cleared for small-holder farming, thus threatening this population. In all, a loss of over 30% of the population is estimated over the past three generations, which we here estimate to be 10 years, much of this loss being irreversible. Although the extent of occurrence is large, the area of occupancy is likely to be < 2,000 km² and the species is known from less than ten locations.

Conservation Actions [top]

Conservation Actions: As this species is found within the village of Enyandong, on a tree in front of the house of the Chief of the village, this is an ideal location for promoting community-based conservation. Local residents here could be encouraged to search for this species in the surrounding forest, perhaps using a species conservation poster as an aid to identification, and to promote protection of any locations where it is found.
