Assessment Information [top]

Red List Category & Criteria: Near Threatened ver 3.1
Year Published: 2010
Date Assessed: 2009-09-13
Assessor(s): Hamilton, S., Bonaccorso, F., Helgen, K. & Allison, A.
Reviewer(s): Lamoreux, J. (Global Mammal Assessment Team), Racey, P.A., Medellín, R. & Hutson, A.M. (Chiroptera Red List Authority)
Listed as Near Threatened because this species is likely in significant decline (but probably at a rate of less than 30% over ten years given the species' tolerance of some degree of habitat modification) because of widespread habitat loss through much of its range, thus making the species close to qualifying for Vulnerable.

Geographic Range [top]

Range Description:This species has been recorded from the islands of Mioko, New Britain, New Ireland, Sakar, Duke of York, and Umboi in the Bismarck Achipelago of Papua New Guinea (Flannery 1995, Bonaccorso 1998). It has been recorded from sea level to 1,200 m asl. Records from the main island of New Guinea are likely vagrants.

Current Population Trend:Decreasing

Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:Animals have been recorded in lowland and hill forests, secondary forest, plantations, logged forest, and in gardens at the forest edge. It is also found on coconut plantations (feeding on coconut flowers). It roosts in vegetation (Flannery 1995, Bonaccorso 1998). Presumably females give birth to a single young. There is male lactation in this species. Lifespan averages 8–10 years and reaches maturity at 1–2 years of age.

Threats [top]

Major Threat(s): The species is threatened by intensive logging activities on New Britain and New Ireland Islands. The species is probably highly threatened through the clearing of land for oil palm plantations and the subsequent loss of roost sites. Logging is most pervasive at low elevations within this species' range (for estimates of forest cover loss on New Britain for the period of 1989–2000, see Buchanan et al. 2008).

Conservation Actions [top]

Conservation Actions: This species is listed on Appendix II of CITES. Field studies are needed to determine important roosting and foraging sites for this species. It does not appear to be present in any protected areas.
