Reviewer(s): Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson and Neil Cox)
Listed as Least Concern in view of its wide distribution, tolerance of a broad range of habitats, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.

Population [top]

Population: It is a locally uncommon species. The total population is widely distributed, and the species is found at many localities.
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: It is a terrestrial species of seasonally flooded dry grasslands, open plains and arid areas. Breeding, and presumably larval development, takes place in many different types of waterbodies. Adults are often found in burrows, and are known to aestivate during dry periods. It is present in cultivated areas and around human settlements.
Systems: Terrestrial; Freshwater

Threats [top]

Major Threat(s): Habitat loss through the general development of infrastructure within the region, and adult mortality through road kill (in India) are threats to this species. Over collection of adults for subsistence use (in India) might also be a threat, as well as the reclamation of wetlands in Sri Lanka.

Conservation Actions [top]

Conservation Actions: Given the wide range of this frog, it is presumed to be present in a number of protected areas. It is protected by national legislation in India.
