Population justification: The species is known from four specimens and a handful of recent records and so the global population is placed in the band 2,500-9,999 mature individuals. This estimate was supported by Davis et al. in prep..
Trend justification: Buchanan et al. (2008) calculated the rate of forest loss within the species's range on New Britain as 9.5% over three generations.
