Population justification: The total population is almost certainly less than 10,000 mature individuals (C. Bowden in litt. 1999, R. Fotso in litt. 1999, H. Thompson in litt. 2000), and it is thus placed in the band 2,500-9,999 mature individuals. This equates to 3,750-14,999 individuals in total, rounded here to 3,500-15,000 individuals.
Trend justification: It has been stated that the species's population is believed to be either stable or declining (Bian et al. 2006). However, given levels of habitat loss and degradation, hunting and disturbance, the population is suspected to be in decline.
