This species is listed as Least Concern because of its presumed large populations, tolerance to land-use change and human encroachment, presence in a number of protected areas and the ability to persist in degraded and even developed areas.
|Range Description:||This species is endemic to the Palawan Island Group, situated between Borneo and the Philippines (Widmann and Widmann, 2004). Since 165,000 years ago, due to rising sea levels, the land connection between the Borneo population and the Palawan population was disrupted (Widmann and Widmann, 2004). This species is found on Palawan Island, Busuanga, and Calauit, and is not found on some of the smaller outlying coral islands like Rasa and Malinau, and also not on the larger land-bridge island of Dumaran (Widmann and Widmann, 2004). Corbet and Hill (1992) also list the species as occurring on Iloc island although some experts doubt this.|

|Population:||The species is geographically restricted and locally moderately common to uncommon in secondary and primary lowland forest (Heaney et al. 1998). Since then it has been reported to be widespread and common in forest, second growth, and agricultural areas on Palawan Island (Kruuk 2000, Esselstyn et al. 2004). It is common in the lowlands, up to at least 300 m (Widmann and Widmann, 2004).|
|Habitat and Ecology:||It is found in lowland forests, primary and secondary, disturbed habitat, including mixed grassland and second-growth forest (Hoogstraal 1951, Rabor 1986, Heaney et al. 1998). The species can also be found in urban areas (GMA Philippines 2006). Little is known about the ecology of this species, though it is known to be found in a wide variety of habitats (Widmann and Widmann, 2004). "It has been recorded from lowland primary and secondary forest, in shrub- and grasslands, freshwater swamp forest, and even within settlements (Widmann and Widmann, 2004)." Dogs and cats do not seem to bother this species due to its potential to excrete a nauseating chemical from its anal glands (Widmann and Widmann, 2004). The main diet of this species consists of worms and soil arhtropods, requiring areas with soft soil for foraging (grasslands typically have extensive root systems which make digging difficult, and it is seen along small streams during the dry season) (Widmann and Widmann, 2004). This species is not restricted to primary forest, it seems that relatively high population densities can occur in secondary forests and shrublands (Widmann and Widmann, 2004), and it is even known to thrive in cultivated areas (Grimwood, 1976).|
|Major Threat(s):||It is rarely hunted by native people, due to its ability to excrete a pungent smell when attacked (Widmann and Widmann, 2004). Although it probably has not suffered from conversion of primary to secondary forest or shrubland, further alteration to grassland or permanent agriculture may pose a threat to this species (Widmann and Widmann, 2004). Car traffic may also pose a threat to this species (Widmann and Widmann, 2004). It is not known if diseases from domestic animals affect it (Widmann and Widmann, 2004)|
|Conservation Actions:||There are no local laws protecting this species.|
