Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): Bonaccorso, F. & Helgen, K.
Reviewer(s): Lamoreux, J. (Global Mammal Assessment Team), Racey, P.A., Medellín, R. & Hutson, A.M. (Chiroptera Red List Authority)
Listed as Least Concern because, although its extent of occurrence is probably less than 20,000 km2, it is distributed on a number of islands, presumably has large population, occurs in a number of protected areas, and it is unlikely to be declining at nearly the rate required to qualify for listing in a threatened category.
Previously published Red List assessments:
1996 Endangered (EN)

Geographic Range [top]

Range Description: This species is endemic to the Raja Ampat Islands (Batanta, Gebe, Salawati, Gag, Waigeo (plus possibly Misool)), and the Biak and Supiori islands (including Owi) in Geelvinck Bay, Indonesia. It is not present on the island of New Guinea (Flannery 1995).

Population [top]

Population: This species is widespread and common within its range.
Current Population Trend: Unknown
Additional data:
Population severely fragmented: No

Habitat and Ecology [top]

Habitat and Ecology: This species roosts in large colonies in both caves and trees. It is commonly found foraging in secondary forest, Pandanus, plantations, and gardens. Flannery (1995) thought that the similar-sized Dobsonia emersa excludes it from caves where the two species co-occur. Of the 14 specimens in the type series collected in December 1909 from Waigeo, seven females were lactating or pregnant. Females observed on Biak-Supiori in September were in an early stage of pregnancy, while on Batanta many pregnant females were observed in October (Flannery1995).
Systems: Terrestrial

Threats [top]

Major Threat(s): There appear to be no major threats to this species. It is unlikely to be hunted within this range (F. Bonaccorso pers. comm.).

Conservation Actions [top]

Conservation Actions: It is present in a number of protected areas. Further taxonomic studies are needed to determine if this species is conspecific with Dobsonia viridis.
