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.
Distribution and population
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 (Buchananet al. 2008).
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.
Buchanan et al. (2008) calculated the rate of forest loss within the species's range on New Britain as 33.8% over three generations. Hence, this decline is expected to continue.
It inhabits lowland rainforest up to 1,200 m. It is thought to tolerate some degree of habitat degradation.
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 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.
