Geographic Range [top]

Range Description:This species is endemic to Bhutan, India and Nepal at altitudes of 1,500 to 3,000 m asl (Molur et al. 2005, Thorington and Hoffmann 2005). Choudhury (2002) observes the subspecies singhei as occurring in Arunachal Pradesh, India. The range in India was extended to include Tawang district and its occurrence is also possible in Tibet (China) (Choudhury 2009).

Population [top]

Population:The population of this species is declining with continuing habitat loss in the region. Molur et al. (2005) stated a 21–50 % loss of its habitat from the last 35 years and similar trends predicted for the subsequent 25 years.
Current Population Trend:Decreasing
Additional data:
Population severely fragmented:Unknown

Habitat and Ecology [top]

Habitat and Ecology:It is an arboreal and crepuscular/nocturnal species. It occurs in tropical and subtropical montane, montane pine and rhododendron forests (Molur et al. 2005, Shreshta pers. comm). The generation time is estimated to be about seven or eight years.
Generation Length (years):7-8

Use and Trade [top]

Use and Trade: Petaurista nobilis is a local livelihood and it is used as food by humans.

Threats [top]

Major Threat(s): Habitat loss and degradation due to logging and mining operations, expansion of human settlements, construction of dams, and hunting for local consumption have been observed to be the major threats for this species in South Asia (Molur et al. 2005). Consruction and road widening in Arunachal Pradesh and Sikkim are major threats (Choudhury pers. comm). Molur et al. (2005) suggested 21–50 % of its habitat has lost from the previous 35 years and similar trends predicted for the subsequent 25 years.

Conservation Actions [top]

Conservation Actions: The species is included in the Schedule II (Part II) of the Indian Wild Life (Protection) Act, 1972. The subspecies singhei occurs in Eaglenest Wildlife Sanctuary and Sessa Orchid Sanctuary in Aruncachal Pradesh (Choudhury 2002). In Sikkim the nominate subspecies occurs in Kangchendzonga National Park, Maenam Wildlife Sanctuary, Barsey Rhododendron Sanctuary and Pangolakha Wildlife Sanctuary while in Bhutan the subspecies singhei occurs in Bumdeling and Sakteng Wildlife Sanctuaries (Choudhury pers. comm). Survey, life history and limiting factor studies and monitoring are recommended for this species (Molur et al. 2005).
