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).

Geographic Range [top]

Range Description: Centropus violaceus is endemic to the islands of New Britain and New Ireland, Papua New Guinea where although it is rather poorly known, it appears to be widely distributed and not uncommon in suitable habitat. It is suspected to have declined moderately rapidly in recent years owing to ongoing clearance of lowland forest (Buchanan et al. 2008).

Population [top]

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.
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: It inhabits lowland rainforest, usually primary or old-growth forest, up to 800 m. It is not thought to tolerate habitat degradation.

Systems: Terrestrial

Threats [top]

Major Threat(s): Lowland forest clearance on New Britain for conversion to oil palm plantations has been intense in recent decades and the island accounts for approximately half of Papua New Guinea's timber exports (Buchanan et al. 2008). On that island, more than 12% of habitat suitable for this species has been cleared in the last 10 years, and this trend is ongoing (Buchanan et al. 2008). This situation is not thought to be much different on New Ireland.

Conservation Actions [top]

Conservation Actions: 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 on both islands.
