Assessor(s): Rajamani, N., Molur, S. & Nameer, P.O.
Reviewer(s): Amori, G. (Small Nonvolant Mammal Red List Authority) & Cox, N. (Global Mammal Assessment Team)
Listed as Vulnerable because it is confined to riparian habitats, and has an area of occupancy of probably less than 2,000 km² in total, its distribution is severely fragmented, and there is continuing decline in the extent and quality of its habitat.

Population [top]

Population:It is a very rare squirrel in the Western Ghats, with very few sightings reported. The population trend indicates a quantitative decrease at a rate of 20% or more in last 10 years and a similar trend in the future is predicted due to habitat loss in the two countries (Molur et al. 2005). This is one of the rarest and most shy Funambulus species that is usually confused with Funambulus layardi in Sri Lanka and Funambulus tristriatus in India (Sanjay Molur pers. comm. 2008).
Current Population Trend:Decreasing
Additional data:
Population severely fragmented:Yes

Habitat and Ecology [top]

Habitat and Ecology:This species is restricted to riparian habitats, especially reedbeds, in tropical evergreen and moist deciduous forest. In Sri Lanka, it is associated with these wetlands in low country wet to mid montane wet zone (Molur et al. 2005) and in bamboo jungles. In the Western Ghats it is associated with Ochlandra sp. Reedbeds in moist forests (N. Rajamani pers. comm.; Molur et al. 2005).

Threats [top]

Major Threat(s): Habitat loss and degradation due to selective logging, collection of non-woody vegetation (reeds), and forest fires have been observed to be the major threats (Molur et al. 2005). Forest fragmentation and pesticide spraying is affecting the species in some parts of its range, while collecting reeds for construction purposes is also threatening its habitat (N. Rajamani pers. comm.).

Conservation Actions [top]

Conservation Actions: The species is not protected by any legislation. It is however, known from the following protected areas in India - Silent Valley National Park, Thekkadi Bird Sanctuary, Chimmony Wildlife Sanctuary, Periyar Tiger Reserve and Wayanad Wildlife Sanctuary in Kerala. In Sri Lanka it is reported from Horton Plains National Park in Central Province and Adam’s Peak Wildlife Sanctuary in Sabaragamuwa Province (Molur et al. 2005). Survey, limiting factor research and captive breeding for species recovery are recommended for this species (Molur et al. 2005).
