Assessment Information [top]

Red List Category & Criteria: Vulnerable A2c+3c+4c ver 3.1
Year Published: 2012
Date Assessed: 2012-05-01

This speciesis classified as Vulnerable because remote-sensing data indicate that there has been a dramatic loss of lowland forest across its range and that it is therefore likely to be undergoing a rapid population decline.

Geographic Range [top]

Range Description: Ninox odiosa is endemic to the island of New Britain Papua New Guinea where although it is rather poorly known, it appears to be not uncommon in suitable habitat. It is suspected to have declined 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 up to 1,200 m. It is thought to tolerate some degree of 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). Over 30% of suitable habitat has been cleared in the last 10 years and this trend is ongoing (Buchanan et al. 2008).

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, on New Britain. 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 island.
