Population justification: Data from 2008 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. It is unclear whether the population has declined since this estimate was made. Forest cover in this species' mapped range has declined by c.5% since 2008 (Global Forest Watch 2022, based on data from Hansen et al. [2013] and methods disclosed therein) and this may have led to equivalent population losses although this requires confirmation.
Trend justification: Between 1997 and 2007, populations at study sites declined by c.20% for reasons that were not fully elucidated (D. Mitchell in litt. 2008), while more recent trend data are lacking. Remote sensing data in the three generations to 2021 suggest forest cover in the species' mapped range was reduced by c.7% (Global Forest Watch 2022, based on data from Hansen et al. [2013] and methods disclosed therein) and, as a forest dependent species, P. decora is suspected of having declined at a similar rate.
