Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): Han, K.H. & Stuebing, R.
Reviewer(s): Hoffmann, M. & Chanson, J. (Global Mammal Assessment Team)
Listed as Least Concern as the species is relatively widespread, common, and although declining in parts of the range (such as Sumatra), these declines are not believed to be at a rate that would warrant listing in a threatened category.
Previously published Red List assessments:
1996 Lower Risk/least concern (LR/lc)

Population [top]

Population: Common on Borneo (Han et al. 2000), but there is little information from Sumatra where they almost certainly have undergone declines (K. H. Han pers. comm).
Current Population Trend: Decreasing
Additional data:
Population severely fragmented: No

Habitat and Ecology [top]

Habitat and Ecology: This species is found mainly in lowland forest, but is also fairly common in fruit orchards and secondary forest. Wells (2005) found that in selectively logged forest with a dense understorey, this species increases significantly.
Systems: Terrestrial

Threats [top]

Major Threat(s): Although this species is found in fruit orchards, it is not present in unforested agricultural areas; thus deforestation remains a threat (K. H. Han pers. comm.).

Conservation Actions [top]

Conservation Actions: This species is very common in the older forests of protected areas on Borneo (K. H. Han pers. comm.). It is listed on CITES Appendix II.
