Population justification: The population is estimated to number 10,000-19,999 individuals based on an assessment of known records, descriptions of abundance and range size (Buchanan et al. 2008, Davis et al. in prep.). This is consistent with recorded population density estimates for congeners or close relatives with a similar body size, and the fact that only a proportion of the estimated Extent of Occurrence is likely to be occupied. This equates to about 6,000-15,000 mature individuals.

Trend justification: Buchanan et al. (2008) calculated the rate of forest loss within the species's range on New Britain as about 19% over three generations (30 years). Less detailed analysis is available for later years but about 2.2% of forest was lost plus 5.2% degraded across New Britain between 2002 and 2014 (Bryan and Shearman 2015). It is inferred that forest loss and degradation has slowed and the species’s rate of decline is now estimated at 10-19% over over three generations (30 years).
