Assessment Information [top]

Red List Category & Criteria: Vulnerable B1ab(iii) ver 3.1
Year Published: 2013
Date Assessed: 2011-03-01

Justification:
Listed as Vulnerable because its extent of occurrence is less than 7,000 km2, it is known from only four localities (each considered a separate location based on a threat from conversion of its habitat to plantations), and there is continuing decline in the extent and quality of its habitat.

Geographic Range [top]

Range Description: Oligodon brevicauda is endemic to the Western Ghats (India) and is known only from the Nilgiri Hills and Anaimalai Hills in Tamil Nadu, from Peermade Hills in Kerala (Boulenger 1894), and recently from Sengaltheri, Kalakkad-Mundunthurai Tiger Reserve, Tamil Nadu (V. Deepak pers. comm. 2011). It is mostly reported based on four specimens collected historically from these areas, with a single recent sighting from Sengaltheri. It is found at elevations of 350 to 1,250 m asl.
