Assessment Information [top]

Red List Category & Criteria: Vulnerable D2 ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Assessor/s: Darbyshire, I. & Cheek, M.
Reviewer/s: Hilton-Taylor, C. & Pollock, C.M. (Red List Programme Office)
Justification:
The area of occupancy of this taxon is less than 1–2 km², this being the estimate for the grassland areas comprising the two (of three) peaks of Mt Kupe from which it has been collected. Since these grassy areas are very precipitous below the peaks, they have not been fully explored and only a rough estimate of the size of the population of P. kupense is possible. It is likely that the number of mature individuals is only a few hundred, but could fall in the range 50–several thousand. This taxon is assessed as Vulnerable due to the very restricted area of occupancy and number of locations such that it is vulnerable to stochastic change (see threats below). Subsequent attempts to relocate this species in 2003 to 2004 have been unsuccessful to date (M. Etuge, pers. comm.). It is possible that this conservation assessment will be downgraded in future if the plant is found in other adjacent montane grassland areas, such as the poorly known Mt Nlonako to the northeast. However, investigations of montane grassland in the Bakossi Mts, the Muanenguba Mts and Mt Cameroon have so far not revealed populations of this plant.

Population [top]

Population Trend: Unknown

Habitat and Ecology [top]

Habitat and Ecology: occurs in montane grassland; 1,900–2,000 m alt.
Systems: Terrestrial

Threats [top]

Major Threat(s): Possibly threatened by stochastic change such as lightning-induced fires or landslides. The species is not threatened by man at present, being found far above the highest limits (ca. 1,100 m alt.) of agriculture on the mountain.

Conservation Actions [top]

Conservation Actions: Rediscover and investigate more fully the populations of this taxon in the grassy areas on the summit of Mt Kupe, possibly using ropes and harnesses. Surveys of other grassy areas on the mountain, such as Kupe Rock, might reveal further subpopulations. Ideally, surveys should be carried out annually over several years so that fluctuations can be recorded and their significance assessed. Surveys are best conducted between October and March, the dry season, when the plant is flowering and fruiting and so conspicuous and easily identifiable.
