Taxonomy [top]

Kingdom Phylum Class Order Family
PLANTAE TRACHEOPHYTA LILIOPSIDA ORCHIDALES ORCHIDACEAE

Scientific Name: Bulbophyllum bifarium
Species Authority: Hook.f.

Assessment Information [top]

Red List Category & Criteria: Vulnerable 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:
First described from a collection by Gustav Mann on Mt Cameroon , this species is now known from 10 locations, with an area of occupancy of < 2,000 km². The lower altitude locations for this taxon, particularly that on the Douala to Bimbia road and at Nyasoso on Mt Kupe, where it was recorded at ca. 800 m, are threatened by forest clearance for plantation agriculture at the former and for small-holder farming at the latter; these locations are likely to be already lost.

Geographic Range [top]

Range Description: Cameroon: Bakossi Mts (3 coll. at 1 site), Mt Kupe (2 coll. at 2 sites), Mt Cameroon (3 coll. at 3 sites), Douala to Bimbia (1 coll.), Mfongu near Bagangu (1 coll.), Bana-Bateha near Fibé (1 coll.), Nkokom Massif near Ndom (1 coll.).

Habitat and Ecology [top]

Habitat and Ecology: An epiphyte in submontane and montane forest; 800–1,800 m alt.
Systems: Terrestrial

Threats [top]

Major Threat(s): The lower altitude sites for this taxon, particularly that on the Douala to Bimbia road and at Nyasoso on Mt Kupe, where it was recorded at ca. 800 m, are threatened by forest clearance for plantation agriculture at the former and for small-holder farming at the latter; these sites are likely to be already lost. The higher altitude sites on Mt Cameroon, Mt Kupe and at Kodmin are, however, less threatened at present.

Conservation Actions [top]

Conservation Actions: Conservation of this taxon should focus upon the Kodmin area of the Bakossi Mts where it appears to be most gregarious and where threats to its habitat are currently limited. A survey of its abundance should be carried out in November, its known flowering period there.
