Habitat and Ecology
It occurs terrestrially in grasslands, including rice plantations. It breeds in temporary pools, and it adapts well to agricultural habitat.
It is common and the population is stable.
There are no generalised threats against this species, although pollution of soil and water due to agriculture, industries and human settlements might be localized threats. It is also threatened by automobile collisions.
It occurs in several protected areas.
Red List Status
Least Concern (LC)
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.
