Description |
JUSTIFICATION
Listed as Least Concern because, whilst the species is is dependent upon a highly fragile habitat in central Borneo, it has a reasonably wide distribution and appears to be tolerant of some disturbance to its forest habitat.
RANGE DESCRIPTION
This species ranges from the mountains of Sarawak and Sabah (Malaysia), and northern East Kalimantan. More recently it has been recorded further East in Tawau Hills National Park (Wells et al. 2007) and in Kalabakan Forest Reserve (Fitzmaurice 2014). It has been recorded up to 1,530 m asl on Mt. Kinabalu (Thorington et al. 2012).
DESCRIPTION
The abundance and population size of this species are not known.
HABITAT AND ECOLOGY
These animals are found in primary forests up to 1,000 m. In one study of varying degrees of forest disturbance, this species was only recorded in unlogged forest (Wells et al. 2007).
THREATS
The native forests of Borneo have been impacted by selective logging, fire, and conversion to plantations at unprecedented scales since industrial-scale extractive industries began in the early 1970s (Gaveau et al. 2014). Lowland rainforests in particular are being heavily degraded (Meijaard and Sheil 2008). In a study of different disturbances the species was only unlogged forest, which might indicate that it is not very tolerant to disturbance (Wells et al. 2007). There has been a decrease in density of this species observed in response to logging (Dahaban et al. 1996). However, in a study conducted in Kalabakan Forest Reserve where different logging regimes are in operation the species was detected across all areas surveyed including highly logged, medium logged and no logging (Fitzmaurice 2014).
CONSERVATION ACTIONS
Further studies are needed into the distribution, abundance, reproduction and ecology of this species. It has been recorded in Tawau Hills National Park (Wells et al. 2007). |
