Listed as Vulnerable because its extent of occurrence is estimated to be less than 10,000 km², while the area of occupancy is estimated at 600 km². based on survey data and available habitats (Molur et al. 2005). It is found in a few severely fragmented locations and is facing a continuing decline in its habitat quality.

|Habitat and Ecology:||It is a nocturnal and fossorial species. It occurs in lowland and montane evergreen forests (Molur et al. 2005).|
|Major Threat(s):||Habitat loss and degradation due to expansion of agriculture, clear-cutting, forest fire in Horton Plains, undergrowth clearing in Knuckles Range, and predation by domestic carnivores have been observed to be the major threats for this species (Molur et al. 2005, W.I.L.D.P.T.S. de A. Goonatilake in litt. 2005).|
|Conservation Actions:||The species is not protected by any legislation. It is known from Horton Plains National Park, Knuckles Range Forest Reserve in Central Province; Delwala Forest Reserve and Sinharaja Forest Reserve in Sabaragamuwa Province. Survey, life history studies and monitoring are recommended for this species (Molur et al. 2005).|
