Population justification: The global population is estimated as 1,000-10,000 individuals (del Hoyo et al. 1994), roughly equivalent to 670-6,700 mature individuals.

Trend justification: The population is suspected to be in decline, but the trend has not been directly estimated. Tracewski et al. (2016) measured the forest loss within the species’s range between 2000 and 2012 as c. 49 km². This roughly equates to a rate of forest loss of 2.7% over three generations (12 years) for this species, assuming that forest loss is continuing at the same rate. Threats known for Tanimbar Scrubfowl include forest clearance and hunting. Thus, given the additional threat from hunting, it is assumed that the rate of population decline may be larger than the rate of forest loss. However, even under this assumption, the rate of decline is unlikely to exceed 20% over three generations.
