Population justification: Recent data suggest that the population may be very small, being estimated at only c.650 individuals, with a maximum of 500 individuals on Fergusson Island, and c.150 individuals on Normanby Island (D. Mitchell in litt. 2008). Based on these estimates, the total number of mature individuals is estimated at 450, with c.350 on Fergusson Island.

Trend justification: Surveys of the populations on Fergusson and Normanby indicate declines of c.20% from c.1997 to 2007 (D. Mitchell in litt. 2008). Satellite imagery suggests that 4.8% forest in the species' range has been lost over three generations (Tracewski et al. 2016). Until further data are available the rate of decline over three generations (27 years) is conservatively suspected to be 25-29%
