This species is known from southeast Thailand (the islands of Koh Chang, Koh Kut and Koh Mehsi), the nearby Thai mainland (at Ok Yam) and from Cambodia (in the Cardamom Mountains and Elephant Mountains) (Smith 1922, Bourret 1942, Ohler et al. 2002, Stuart and Emmett 2006). The record from northern Lao PDR (Stuart 1999) is in error. Records from southern Viet Nam (Orlov et al. 2002, Nguyen 2005) refer to Limnonectes poilani (Ohler et al. 2002). It has been recorded between 300 and 1,200 m asl in the Cardamom Mountains (Stuart and Emmett 2006).
Habitat and Ecology
It has been recorded from hill, evergreen forest and breeds in slow moving sections of streams. The species lays eggs and has a free-living larval stage. It is also found in anthropogenic habitats, such as gardens and plantations. Individuals are found dispersed on the forest floor outside the breeding season.
It is a common species in the Cardamom Mountains (S. Swan pers. comm.)
Threats are mostly unknown although wildfire and future logging might affect the species.
Koh Chang is a National Park and protected areas have been established in the Cardamom Mountains. Taxonomic revision of this species is needed. This is a protected species by law in Thailand.
We follow Ohler et al. (2002) in treating Limnonectes poilani as a species distinct from L. kohchangae.
