Assessor(s): Yuan Zhigang, Zhao Ermi, Shi Haitao, Diesmos, A., Alcala, A., Brown, R., Afuang, L., Gee, G., Sukumaran, J., Yaakob, N., Leong Tzi Ming, Yodchaiy Chuaynkern, Kumthorn Thirakhupt, Das, I., Iskandar, D., Mumpuni & Robert Inger
Reviewer(s): Chanson, J.S., Cox, N.A. & Stuart, S.N.
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 to qualify for listing in a more threatened category.

Geographic Range [top]

Range Description:This is a widely distributed frog. It is known from coastal southern China in Guangxi and Hainan Provinces, from Great Nicobar Island in India, and from most countries in Southeast Asia including the Philippines. In New Guinea introduced populations are known from the Sorong, Manokwari, Nabire and Jayapura areas of Papua, Indonesia. It has been introduced to Guam, although its breeding status and range in this island are unclear (Christy et al. 2007).
Countries occurrence:
Brunei Darussalam; Cambodia; China; India; Indonesia (Papua - Introduced); Lao People's Democratic Republic; Malaysia; Philippines; Singapore; Thailand; Viet Nam

Population [top]

Population:It is common to abundant in appropriate habitats. It is introduced to New Guinea and its population there is increasing.
Current Population Trend:Increasing
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:It occurs in mangrove forest, estuarine habitats, swamps and open, wet coastal areas, such as roadside ditches and puddles. It also thrives in man-made environments such as rice paddy fields. Tadpoles develop in rain pools above the high water line on the mainland, and in any body of standing water in the Philippines. It is tolerant of moderate salinity.
Systems:Terrestrial; Freshwater

Use and Trade [top]

Use and Trade: This species is harvested for human consumption.

Threats [top]

Major Threat(s): Over-harvesting is a potential threat to this species. Habitat destruction and degradation might also be threatening some populations, in particular the destruction of mangroves for wood, expansion of human settlements, and the construction of roads. There are no threats to the species in the Nicobar Islands. In New Guinea this species is probably a threat to native fauna.

Conservation Actions [top]

Conservation Actions: The range of this species includes a number of protected areas. Monitoring of populations and harvest levels in countries where it is exploited is needed. This species needs to be eradicated from New Guinea, and its breeding status in Guam needs to be determined. It is protected by national legislation in India.
