Red List Category & Criteria: Near Threatened ver 3.1

This species is listed as Near Threatened because although the species is widespread and occurs in numerous protected areas and can occur in logged and secondary forest, overall forest conversion rates in its entirely Sundaic range are very high. It almost qualifies as threatened under criterion A2c, because it is only found at low elevations and there has been rapid forest loss of lowland forest.
Previously published Red List assessments:

Geographic Range [top]

Range Description:This species occurs on Peninsular Malaysia and Thailand, Sumatra, Borneo, and small adjacent islands (Thorington et al. 2012). It is found at elevations below 300 m asl (E. Meijaard pers. comm).
Countries occurrence:
Brunei Darussalam; Indonesia (Kalimantan); Malaysia (Peninsular Malaysia, Sabah, Sarawak); Singapore; Thailand
Additional data:
Upper elevation limit (metres):300

Population [top]

Population:This species has been rarely encountered. One long term study in Brunei Darussalam only captured the species in a disturbed kerangas patch in Berakas forest reserve, which suggests that the species is rare and extremely difficult to trap (Charles and Ang 2010).
Current Population Trend:Decreasing
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This is a diurnal and terrestrial species (Saiful and Nordin 2004), occurring in lowland primary rainforest, logged forests, and 40 year old regrowth. In a study in Sabangau Forest, central Kalimantan, it was only found in dense inner forest (Schep 2014).

Threats [top]

Major Threat(s): It is threatened by habitat loss due to logging and agricultural conversion. Some studies have shown that densities of the species decreased after logging (Meijaard and Sheil 2008), although a recent study showed that there were high capture rates of the species at sites with logging residues compared to those without logging residues (Yamada et al. 2016).

Conservation Actions [top]

Conservation Actions: It occurs in several protected areas, for example in the Hala-Bala Wildlife Sanctuary on Thai/Malaysian border (Kitamura et al. 2010), in Berakas Forest Reserves, Brunei Darusalam (Charles and Ang 2010), and in Central Catchment Nature Reserve and Bukit Timah Nature Reserve, Singapore (Lim and Yeo 2012).
