Assessment Information [top]

Red List Category & Criteria: Data Deficient ver 3.1
Year Published: 2010
Date Assessed: 2009-10-19
Assessor(s): IUCN SSC Amphibian Specialist Group
Reviewer(s): Cox, N.A. & Hoffmann, M.
Contributor(s): Angulo, A. & Biju, S.D.
Justification:

Listed as Data Deficient since it has only recently been described, and there is still limited information on its extent of occurrence, status and ecological requirements. However, it is likely that it may be reassessed to a threatened category upon further study, although the information currently available does not allow for the unequivocal assignment of this species to one of the threatened categories.

Geographic Range [top]

Range Description:This species is known from two high-altitude (1,700 and 2,000 m asl) localities in the Palani Hills and surrounding areas, south of the Palghat Gap: Kodaikanal, in Tamil Nadu, and Mattupetti, in Kerala, India (Biju et al. 2008).

Population [top]

Population:

This seems to be a rare species, and it appears to be declining. However, further field work is required to confirm this (S.D. Biju pers. comm. October 2009).

Current Population Trend:Decreasing
Additional data:

Habitat and Ecology [top]

Habitat and Ecology:This species seems to be restricted to disturbed evergreen sholas (isolated montane forest patches). Individuals can be found close to mountain streams, in habitats such as leaf litter, rock patches, tall grass clumps and the undergrowth of shrub vegetation (Biju et al. 2008). Foam nests can be deposited on rock surfaces, on the ground up to 2 m above water level, and near streams, and may contain ca 185 eggs (Biju et al. 2008).
Systems:Terrestrial; Freshwater

Use and Trade [top]

Use and Trade:

There are no reports of this species being utilized.

Threats [top]

Major Threat(s):

The main threat to this species is the conversion of the forested areas that are its habitat. The species appears to be in decline at the type locality primarily because of habitat alteration (the forest is within the town limits and is exploited by local residents), likely due to small-scale agriculture, rural and/or urban development and pollution (S.D. Biju pers. comm. October 2009).

Conservation Actions [top]

Conservation Actions:

The type locality is within a forested area owned by the government, although it has not been given a protected area status. This area is in the midst of town and local residents depend on the forest for resources (S.D. Biju pers. comm. October 2009). The other known locality is also outside a protected area, and the surrounding forests are completely degraded (S.D. Biju pers. comm. October 2009). Further research into this species' population status, life history and threats is needed.
