|Scientific Name:||Nyctibatrachus major Boulenger, 1882|
Rana travancorica Annandale, 1910
|Taxonomic Notes:||There is quite considerable intraspecific variation in this taxon (Biju 2001).|
|Red List Category & Criteria:||Vulnerable B1ab(iii) ver 3.1|
|Assessor(s):||S.D. Biju, M.S. Ravichandran, Anand Padhye, Sushil Dutta|
|Reviewer(s):||Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson and Neil Cox)|
Listed as Vulnerable because its Extent of Occurrence is less than 20,000 km2, its distribution is severely fragmented, and there is continuing decline in the extent and quality of its forest habitat in the Western Ghats of India.
|Range Description:||This species has a wide distribution in the Western Ghats of India. It has been recorded from elevations up to 1,000m asl in Kerala.|

|Population:||There is no information on the population status of this species, partly hindered by the large degree of intraspecific variation evident in this species.|
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||It inhabits torrential streams in evergreen, moist deciduous forest. Although it may be found in forest edge, it does not occur in degraded habitats. Breeding takes place in streams.|
|Major Threat(s):||The conversion of forested land to agricultural use (including tea, coffee, and paddy fields), and the harvesting of wood and timber by local people are threats to this species. The construction of roads and the development of tourism in the region are leading to further loss and degradation of the species' habitat.|
|Conservation Actions:||The species has been recorded from several protected areas throughout the Western Ghats. There is an urgent need for a taxonomic revision of this species, since it almost certainly represents a complex of several distinct and isolated forms. It is protected by national legislation.|
