From the IUCN Red List Species Account:

Range Description

This species is known from extreme southern Peninsular Thailand, peninsular Malaysia (and Sarawak) and Singapore to Indonesia (including Sumatra and Kalimantan), up to 150m asl. It is likely to occur a little more widely than current records suggest.

Habitat and Ecology

It inhabits shallow, gentle streams and nearby swampy areas including peat swamps, very flat alluvial forests (both primary forest and mature secondary growth), and overgrown plantations. The eggs are laid in sandy streambeds but no nest is constructed (Kiew 1984c).

Population

It is generally not rare, but it is also not an abundant frog (Lim and Lim 1992); it is considered rare in Thailand.

Population Trend

Decreasing

Major Threats

The major threat to this species is deforestation. It is also collected for subsistence use and trade (Lim and Lim 1992; P. van Dijk pers. comm.), but most collection pressure is deflected from it by the sympatric occurrence of the larger and more common Limnonectes blythii.

Conservation Actions

It occurs in several protected areas, although more effective conservation of peat swamps and low alluvial rainforests is needed.

Taxonomic Notes

This species was previously hidden within the Limnonectes blythii-macrodon complex.
