This species is listed as Near Threatened because its lowland forest habitat is suffering conversion to oil palm plantations and logging, which is likely to be causing a moderately rapid population decline.
|Previously published Red List assessments:|
|Range Description:||Ducula subflavescens is endemic to the Admiralities and Bismarcks, including Manus, Lou, Nauna, Lavongai, New Ireland, New Britain, Lolobau,Watom and Duke of York, and possibly other nearby small islands in Papua New Guinea. It is locally common on New Britain in flocks of up to a few tens of birds but on New Ireland there are recent records only from the far south and there are only two recent records from Manus.|
Native:Papua New Guinea

|Population:||The population is estimated to be in the band 10,000-19,999 mature individuals, equating to 15,000-29,999 individuals in total, rounded here to 15,000-30,000 individuals.|
Trend Justification: Buchanan et al. (2008) calculated the rate of forest loss within the species's range on New Britain as 20.7% over three generations; the actual rate of decline may be higher because of other factors.
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||It is a nomadic forest species, usually seen in lowland forest but recorded sporadically up to 900 m on New Britain (Gilliard and LeCroy 1967, Finch and McKean 1987, D. Bishop in litt. 1996, 1999, Dutson 2011) and 560 m on New Ireland and across Manus (Dutson 2011). It may have a requirement for coastal or lowland riverine forest (Gibbs in prep.) and most records are from primary forest.|
|Continuing decline in area, extent and/or quality of habitat:||Yes|
|Generation Length (years):||5|
|Major Threat(s):||Most lowland forest and especially coastal forest in this species's range is threatened by logging and conversion to oil palm plantations. On New Britain, 20% of forest within the species elevational range was cleared during the last 15 years (Buchanan et al 2008). It appears not to be threatened by hunting (G. Dutson pers. obs. 1997-1998).|
Conservation Actions Underway
None is known. Conservation Actions Proposed
Identify and effectively protect a network of reserves, including some containing large areas of unlogged lowland forest and some large community-based conservation areas. Continue to monitor trends in forest loss. Research its tolerance of degraded forest. Monitor populations in a number of primary forest and degraded forest sites across the islands.
