Assessment Information [top]

Red List Category & Criteria: Endangered B1ab(ii,iii)+2ab(ii,iii) ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): Chakraborty, S., Nameer, P.O. & Molur, S.
Reviewer(s): Amori, G. (Small Nonvolant Mammal Red List Authority) & Cox, N. (Global Mammal Assessment Team)
Listed as Endangered, in view of its extent of occurrence of less than 5,000 km² and area of occupancy of less than 500 km², with all individuals in fewer than five locations, and a continuing decline in the extent and quality of its habitat in its inferred range around the protected areas it has been recorded from.
Previously published Red List assessments:
2000 Vulnerable (VU)
1996 Endangered (EN)

Geographic Range [top]

Range Description: This species is presently known only from four localities, largely in the Western Ghats in southern India - the type locality of Thrissur (Kerala), Eravikulam National Park (Kerala), Palni Hills (Tamil Nadu) and Upper Bhavani (in Mukurthi National Park, Tamil Nadu) (Pradhan and Kurup 2001; Shankar 1998). The 19th century type locality is from Trissur, Kerala state, southern India - this is near sea level and may not be the exact type locality (Molur et al. 2005). It has been recorded from 1,500 to 2,500 m asl.

Habitat and Ecology [top]

Habitat and Ecology: This is a nocturnal and crepuscular animal that lives in montane grassland-shola habitat (Molur et al. 2005).
Systems: Terrestrial

Threats [top]

Major Threat(s): This species inhabits a small area, and much of its known and projected extent of occurrence is under threat from habitat conversion for plantations (tea, pines, eucalyptus, wattles) (Molur et al. 2005).

Conservation Actions [top]

Conservation Actions: The species is protected in the Eravikulam National Park in Kerala and Mukurthi National Park in Tamil Nadu (Molur et al. 2005). Detailed surveys, ecological and population studies are urgently required. Taxonomic studies between the northern and southern populations to establish the their identities recommended (S. Molur pers. comm.).
