Population: In Viet Nam it was the most locally common tree frog (Inger, Orlov and Darevsky 1999).
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: It is found in substantial numbers in rainforest. It makes foam nests in trees above quiet parts of streams and swampy floodplain (Inger, Orlov and Darevsky 1999).
Systems: Terrestrial; Freshwater

Threats [top]

Major Threat(s): Deforestation of the Kon Tum-Da Lat Plateau (Darevsky and Orlov 1997; Inger, Orlov and Darevsky 1999) and other systemic impacts are prime concerns for this species. The amount of available habitat within its range is very limited.

Conservation Actions [top]

Conservation Actions: The only known location in Cambodia is within Phnom Nam Lyr Wildlife Sanctuary. Herpetological surveys of existing protected areas on the Kon Tum Plateau are needed to determine the presence of this species in existing protected areas. Protected areas in the Buen Luoi-Tram Lap-Kon Cha Ran area are in need of improved management.
