Little is known on ecology of this species. It is found near rivers, in lowland primary and secondary forest and in plantations (Payne et al., 1985; Rabor, 1986; Heaney et al., 1998). Payne et al. (1985) list this species as occurring from sea level up to 1,500 m.

It is likely to be found near rivers in the Philippines (Rabor, 1986; Heaney et al., 1998). On Borneo, it occurs in lowland primary and secondary forest, as well as plantations and in gardens (Payne et al., 1985). In Sarawak, this species occurs in acacia plantations within mosaic or patchy forest or peat swamp forest. It is widespread in the hills and lowlands, but occuring up to 1,280 m elevation in the Kelabit uplands in Sarawak (Medway 1965, 1977). However, in Penisular Malaysia, all records have been from elevations of less than 100 m in primary or regenerating evergreen forest (Wells 1989). The species is currently being studied in Wildife Krau Reverve in Peninsular Malaysia in order to obtain more information on its ecology (Jennings et al, in prep.; Malaysia Carnivore Project, 2006).

  Lower Risk/least concern

The population status is poorly known. In the Philippines, this species is restricted to Palawan where it is quite rare (Widmann pers. comm). This species is widespread, and probably common, though its current status is poorly known (Heaney et al. 1998). Medway (1967) found that it was not common.

Unknown

Major threats are unknown, though it is eaten in some parts of Sarawak and is locally considered a pest in agricultural areas.

It is protected in all of Malaysia and Indonesia. Field surveys, ecological studies and assessments of any possible threats are urgently needed.
