Geographic Range [top]

Range Description:This widely distributed species is present in northeastern South Asia, southern China and western Southeast Asia. In South Asia, this species is widely distributed in Bangladesh, Bhutan, India and Nepal at elevations of 500 to 1,560 m asl (Molur et al. 2005). In China, it has been recorded from southern Yunnan (Smith and Xie 2008). In Southeast Asia, it is largely confined to western and central Myanmar.

Population [top]

Population:The species is rare in Nepal (Shrestha pers. comm.), fairly common in Bangladesh (Sarker pers.comm.), and stable in Myanmar (Lunde, Duckworth, Lee and Tizard pers. comm.). In Chillapat forest, West Bengal, India, the density was estimated at 0.05 individuals per hectare in 1983. However, a similar study in 2002 revealed the density to be 0.03 individuals per hectare due to the decrease in canopy cover from 65 to 40 percent (S. Chakraborty pers. comm. 2005).
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:In general, this is a diurnal and arboreal species that occupies mid canopy temperate, tropical and subtropical moist forest with thick to moderate evergreen forest patches (Molur et al. 2005). In Nepal, it has been reported from riverine woodland (Shrestha pers. comm.). It appear to be tolerant of some habitat modification. In Bangladesh and China the species has been recorded from gardens, plantations (including bananas) and cane shrubs (Sarkar pers. comm. and Smith and Xie 2008). The species reproduces once each year, with a litter size averaging three to four young (Smith and Xie 2008).

Threats [top]

Major Threat(s): In South Asia, this species is threatened by habitat loss resulting from shifting agriculture, small-scale and selective logging, clear cutting of forest, the establishment of human settlements, forest fires, and hunting for local consumption (Molur et al. 2005). In China, it is generally threatened by habitat loss (Wang, Zheng, and Kobayashi 1989). The species is used for medicinal purposes in Nepal (Sarker pers. comm.). The threats in Southeast Asia are not known.

Conservation Actions [top]

Conservation Actions: It is listed in the Schedule II of the Indian Wildlife (Protection) Act, 1972. It is known from the following protected areas in South Asia - Namdapha National Park and Pakhui Wildlife Sanctuary in Arunachal Pradesh, and Gorumara National Park and Mahananda Wildlife Sanctuary in West Bengal in India; Royal Chitwan National Park in Central Nepal (Molur et al. 2005). Survey and monitoring are recommended for this species (Molur et al. 2005).
