Assessment Information [top]

Red List Category & Criteria: Vulnerable B1ab(iii) ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Assessor(s): S.D. Biju, Gajanan Dasaramji Bhuddhe, Sushil Dutta, Karthikeyan Vasudevan, Chelmala Srinivasulu, S.P. Vijayakumar
Reviewer(s): Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson and Neil Cox)
Justification:
Listed as Vulnerable, because its Extent of Occurrence is less than 20,000 km2, its distribution is severely fragmented, and there is a continuing decline in the extent and quality of its forest habitat in southern India.

Geographic Range [top]

Range Description: This species is believed to be restricted to the southern Western Ghats, Ponmudi Hills (Kerala and Tamil Nadu), Wayanad and the Silent Valley (Kerala), and Saklespur, Hassan District (Karnataka) in India. The distribution record in the Shevaroys Hills of the Eastern Ghats, as reported in Dutta (1997), requires further confirmation. It has been reported from elevations of 300-950m asl.

Population [top]

Population: It is a locally common species.
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: It is found in tropical moist evergreen and deciduous forests, and coffee plantations with a natural canopy cover. It can be found in tree holes between two and four metres above ground level (Inger et al. 1984), and in the leaf-litter substrate. It may also be found in abandoned eucalyptus plantations close to forest. It presumably breeds by larval development, like other members of its genus, but it is not known whether or not it requires waterbodies for breeding.
Systems: Terrestrial

Threats [top]

Major Threat(s): The major threat to this species is habitat loss due to conversion to agricultural land (including coffee plantations) and human settlements.

Conservation Actions [top]

Conservation Actions: It has been recorded from Wynaad Wildlife Sanctuary and Silent Valley National Park, both in Kerala, which form part of the Nilgiri Biosphere Reserve. It is also present in the Ponmudi Hills of Kerala.
