Population justification: This species’s population is estimated to number 1,000-2,499 individuals, thought to be roughly equivalent to 600-1,700 mature individuals, based on an assessment of known records, descriptions of abundance and its estimated range size (Donegan and Salaman 2012).

Trend justification: A rapid population decline is assumed owing to habitat loss and presumed hunting pressure. Forest loss has been low within the range (<2% over three generations; Tracewski et al. 2016); however, due to the combined impacts of habitat loss and hunting, overall rates of decline are thought to fall within the band of 1-19% over three generations.
