Synonym/s:
Impatiens sakerana Hook.f. [orth. error]

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:
Although secure on Mt Cameroon, and probably Bioko, forest on Muanenguba and in the Bamenda Highlands has been under pressure from grassland fires set by graziers and for clearance for agriculture; forest in the Kilum-Ijim area outside the protected area having seen a reduction in cover of ca. 25% in eight years of the 1980s and 1990s (Moat in Cheek et al. 2000). Assuming a generation time of ten years, it is estimated that about 30% habitat loss may have occurred in the last 30 years.
