Population justification:
Based on the recorded population densities (1-2.25 individuals/km2 [Bloch et al. 1991] and 17.1, 2.3 and 6.7 individuals/km2 [Jacobs and Walker 1999]) and the area of mapped range (16,570 km2), and assuming that between 10.3% and 11.3% of the range is occupied, the population is estimated to fall within the band 2,770-9,650 individuals, roughly equating to 1,850–6,430 mature individuals, rounded here to 1,800–6,500 mature individuals.
Trend justification: An analysis of deforestation from 2000-2012 found that forest within the species's range was lost at a rate equivalent to 1.9% across three generations (Tracewski et al. 2016). Hunting may also be contributing to declines. Overall, the species is assumed to decline at < 10% over three generations.
