Population justification: Ferguson-Lees and Christie (2001) stated that the population was most unlikely to exceed three figures, however even though the species occurs at low densities it has an extremely large range and this estimate seems implausibly low. The population is therefore preliminarily suspected to lie in the range 1,000-2,499 mature individuals. This equates to 1,500-3,749 individuals in total, rounded here to 1,500-4,000 individuals.
Trend justification: The population is suspected to be in decline owing to ongoing habitat destruction and unsustainable hunting.
