Population justification: The population is estimated to number 10,000-19,999 individuals based on an assessment of known records, descriptions of abundance and range size. This is consistent with recorded population density estimates for congeners or close relatives with a similar body size, and the fact that only a proportion of the estimated Extent of Occurrence is likely to be occupied. This estimate is equivalent to 6,667-13,333 mature individuals, rounded here to 6,000-15,000 mature individuals.

Trend justification: Rates of forest loss are not as great as once feared and local inhabitants are also protecting their forest. The species is therefore suspected to have experienced a decline of only 1-19% over the last ten years.
