Population justification: The population is estimated to number 50-249 mature 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 75-374 individuals in total, rounded here to 70-400 individuals.
Trend justification: The population is suspected to be in decline owing to habitat loss and hunting pressure, although the likely rate of decline has not been estimated.
