Population justification: G. Dutson (in litt. 2002) estimated that fewer than 10,000 individuals survive, so it is placed in the band 2,500-9,999 individuals here. This equates to 1,667-6,666 mature individuals, rounded here to 1,500-7,000 mature individuals.

Trend justification: Buchanan et al. (2008) calculated the rate of forest loss within the species's range on New Britain as 11.2% over ten years.
