From the IUCN Red List Species Account:


Range Description

This relatively widespread species is known from 100–1,200 m Asl across much of central and southern Viet Nam and in eastern Cambodia (Smith 1924, Inger et al. 1999, Bain et al. 2007, Hendrix et al. 2007, Nguyen et al. 2009, Tran et al. 2010, J. Rowley unpubl. data). These are unlikely to represent the actual limits of the species' range as similar habitat and elevations to those in the species' known localities extend into adjacent parts of central and southern Laos. Further surveys in these areas may uncover its presence there, therefore its range has been projected beyond known sites to include these areas of suitable habitat. The species' EOO is 336,160 km2, which represents six threat-defined locations.

Habitat and Ecology

This species is associated with evergreen forest and has most commonly been observed around pools and slow-moving stream sections (Inger et al. 1999, J. Rowley unpubl. data). Reproduction has been observed in both Spring and Autumn, when eggs were deposited in foam nests on rocky surfaces at the banks of streams and on the trunks of trees in flooded plains (Inger et al. 1999). Tadpoles of the species at stage 41 (Gosner 1960) have been observed in early September (Hendrix et al. 2007).


The size and trends of this species' population are not known, but it has been described as the most locally abundant tree frog at one locality in Gia Lai Province (Inger et al. 1999), and has been observed quite commonly and often in large numbers throughout its range (Smith 1924, Inger et al. 1999, Bain et al. 2007, Hendrix et al. 2007, Nguyen et al. 2009, Tran et al. 2010, J. Rowley unpubl. data). It is likely that ongoing forest loss associated with expanding agriculture throughout Southeast Asia (Meyfroidt and Lambin 2008, Sodhi et al. 2009, Meyfroidt et al. 2013) is causing some populations declines.

Population Trend


Major Threats

Habitat loss and degradation due to the effects of rapidly expanding agriculture is an ongoing threat to biodiversity throughout Southeast Asia (Sodhi et al. 2009). In the Central Highlands of Viet Nam, where this species is most commonly encountered, this is a particularly pressing threat; large areas of forest are converted to agricultural land to grow cash crop plantations (e.g. rubber, coffee and tea) (Meyfroidt and Lambin 2008, Meyfroidt et al. 2013). High rates of deforestation for logging and agricultural encroachment on natural forest are also ongoing in much of Laos and Cambodia, where the species is also known or expected to occur (Sodhi et al. 2009). An online search revealed that this species is at least occasionally available for sale as a pet. As with other large, charismatic Rhacophorid species, unsustainable harvest for the international pet trade may also represent a threat to this species' persistence (Rowley et al. 2010).

Conservation Actions

Conservation Actions
This species has been recorded in various protected areas including Nui Ong and Ngoc Linh Nature Reserves in Viet Nam (J. Rowley unpubl. data) and Virachey National Park in Cambodia (Stuart et al. 2006). A number of other protected areas are included throughout this species' predicted range. It very likely occurs in some of these also. 

Research Needed
Addressing the lack of data is the first step towards ensuring this species' long-term persistence; further research on its true distribution, threats, and the size and trends of its population would inform conservation decisions.

Red List Status

Least Concern (LC)


Listed as Least Concern as this species is relatively widespread, with an extent of occurrence (EOO) of 336,160 km2.
