Population justification: It is generally rare (Butynski et al. 1997), and reporting rates have been dropping (S. Cichon, M. McQuillan and E. Meyjes in litt. 2016). Its population size had previously been estimated to be in the range of 2,500-4,999 mature individuals, but given the decline in reporting rate and a lack of recent sightings this is now likely to be an overestimate (S. Cichon, M. McQuillan and E. Meyjes in litt. 2016). Therefore, the population size is precautionarily suspected to fall in the range of 1,000-2,500 mature individuals with no subpopulation containing >250 mature individuals.

Trend justification: The species's population is suspected to be declining in line with the clearance and degradation of forest within its range, although the likely rate of decline has not been estimated.
