Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor/s: Aplin, K. & Helgen, K.
Reviewer/s: Amori, G. (Small Nonvolant Mammal Red List Authority) & Schipper, J. (Global Mammal Assessment Team)
Justification:
Listed as Least Concern as although it has a very restricted range, it is apparently common, and seems fairly adaptable, being found in secondary growth and other modified habitats.
History:
1996 Lower Risk/near threatened (Baillie and Groombridge 1996)

Geographic Range [top]

Range Description: This is known only from Obi and Bisa islands, south of Halmahera, Indonesia (Flannery 1995; Helgen 2003). All known specimens have been taken from lowland areas.

Population [top]

Population: It is known by the holotype from Obi, and a small series from Bisa. Flannery (1995) noted it was common around their camp on Bisa.
Population Trend: Unknown

Habitat and Ecology [top]

Habitat and Ecology: Flannery (1995) collected this species in secondary growth along Durian Creek near Madupolo on the island of Bisa. Surrounding slopes were covered with either gardens or young regrowth, although some forest persisted in the creek valley. Flannery (1995) observed it feeding on fruit of Piper aduncu, up to 3 m above ground; some individuals were trapped on the ground, among rocks and ferns on a creek bank.
Systems: Terrestrial

Threats [top]

Major Threat(s): The major threat is likely to be habitat loss due to logging, although it seems somewhat tolerant of habitat disturbance.

Conservation Actions [top]

Conservation Actions: It is currently not present in protected areas, although a protected area has been proposed for Obi. There is clearly a need for more effective habitat protection, and for additional survey work on both islands to determine its current status.
