This species is listed as Near Threatened because it is likely to be undergoing a moderately rapid population decline as a direct result of conversion of lowland forest to oil palm plantations (revealed through remote sensing).
|Previously published Red List assessments:|
- 2012 – Near Threatened (NT)
- 2008 – Near Threatened (NT)
- 2004 – Least Concern (LC)
- 2000 – Lower Risk/least concern (LR/lc)
- 1994 – Lower Risk/least concern (LR/lc)
- 1988 – Lower Risk/least concern (LR/lc)
|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 18.5% over three generations.
