Population justification: In 1998, the population in Bakossi, Cameroon, one of the most important sites for the species, was estimated at several thousand individuals, thus as a preliminary population estimate the species is placed in the range bracket for 10,000-19,999 individuals. This equates to 6,667-13,333 mature individuals, rounded here to 6,000-15,000 mature individuals. Further documentation is required.

Trend justification: The population is suspected to be in decline owing to the effects of forest clearance for cultivation, logging for timber and firewood, fires and intensive grazing by livestock; and as forest patches become smaller population densities decrease (F. D. Dami in litt. 2016). The likely rate of decline, however, has not been estimated.
