Population [top]

Population:This species is reported to be restricted to disturbed areas in primary forest and is often the most common small mammal found in logged forests in Sabah, Borneo (occurring at 6-16 individuals/ha) (Wearn pers. comm). However, little population information is known for this species.
Current Population Trend:Decreasing
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:It is a terrestrial species found in forest, as well as in rice paddies (but only where surrounded by forest) (Payne et al. 1985). It is mostly a lowland species on Borneo, but can be found as high as 2,100 m asl (Nor 2001, Musser and Carleton 2005). Wilson et al. (2006) reported this species in an acacia plantation and in a fragmented forest in Borneo. Records also suggest that this species can occur in mangrove swamp and secondary forest at Kuala Selangor State Park (Chuluun et al. 2005). This species is also found in oil palm habitats in Sabah, Borneo, and although found at low densities (less than 1 individual/ha), it may be more abundant than other small mammals found in this habitat. Also found in the Maliau Basin Conservation Area, Sabah, Borneo (Wearn pers. comm.).
Generation Length (years):1.7

Use and Trade [top]

Use and Trade: No use and trade information is available for this species.

Threats [top]

Major Threat(s): The major threat to this species is widespread habitat loss in the lowlands of Sumatra and Borneo.

Conservation Actions [top]

Conservation Actions: It is recorded from several protected areas, such as Mt. Kinabalu National Park. It has recently been found during surveys of Gunung Stong State Park, Kelantan, and Wang Kelian State Park, Perlis, in Malaysia (Jayaraj et al. 2012, Jayaraj et al. 2013).
