Kingdom Phylum Class Order Family
ANIMALIA CHORDATA AMPHIBIA ANURA NASIKABATRACHIDAE

Scientific Name: Nasikabatrachus sahyadrensis
Species Authority: Biju & Bossuyt, 2003
Taxonomic Notes: This species has been reported from several additional localities, although these likely refer to undescribed species (S.D. Biju pers. comm.)

Assessment Information [top]

Red List Category & Criteria: Endangered B1ab(iii) ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Assessor(s): S.D. Biju
Reviewer(s): Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson and Neil Cox)
Justification:
Listed as Endangered because its Extent of Occurrence is less than 5,000 km2, all individuals are in fewer than five locations, and there is continuing decline in the extent and quality of its habitat in the Cardamom Hills.

Geographic Range [top]

Range Description: This species is endemic to the Western Ghats in India, and is known from only two localities, both in Idukki District in the Cardomom Hills in Kerala: Kattapana; and near Idukki town. Its recorded altitudinal range is 850-1,000m asl. It is likely to occur more widely.

Population [top]

Population: It is a rare species, though very hard to find. Only 135 specimens have so far been observed, and, of these, only three have been females.
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: It has been found in disturbed secondary forest contiguous with montane evergreen forest, but presumably occurs in undisturbed forest as well (though apparently it does not survive in open, completely cleared habitats). For most of the year it is a fossorial species, living from 1.3-3.7m below ground. It comes to the surface for a few weeks a year to breed in temporary and permanent ponds and ditches by larval development. It often breeds in ponds close to streams.
Systems: Terrestrial; Freshwater

Threats [top]

Major Threat(s): The main threat is forest loss due to expanding cultivation (of coffee, cardamom, ginger and other species).

Conservation Actions [top]

Conservation Actions: It has not yet been recorded from any protected areas, making the protection of forest habitat within its range an urgent priority.
