Range Description

This species is currently known from 470–1,500 m Asl in northern (Bounlenger 1903, Orlov, 1997, Inger et al. 1999, Orlov et al. 2002, Nguyen et al. 2009) and central (Luu et al. 2014) Viet Nam. These are unlikely to represent the actual limits of the species' range as similar habitat and elevations to those in its known localities occur in many intervening provinces in both Viet Nam and Lao PDR, as well as north into southern Yunnan and Guangxi Provinces, China. 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. This species' EOO is 244,143 km2, which consists of six threat-defined locations.

Habitat and Ecology

This species occurs in primary evergreen forest and is associated with steep, rocky cliffs (Orlov 1997). Reproduction has been observed between March and December (Orlov et al. 2006). This species deposits eggs in water-filled rock cavities, where the tadpoles remain until metamorphosis (Orlov 1997).

Population

Little is known about the size of this species' population except that it has been detected in several surveys (Bounlenger 1903, Orlov 1997, Inger et al. 1999, Luu et al. 2014), and was described as abundant at Tam Dao, northern Viet Nam in the 1990's (Orlov 1997). Further research is needed to determine the species' true abundance. Deforestation continues to affect habitat in this species' range (Sodhi et al. 2009), and is very likely causing some declines. There are captive populations of the species in Vietnamese (Gawore et al. 2012) and European (Orlov et al. 2006, Rauhaus et al. 2012) zoological institutions, as well as in private collections.

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). Recent satellite imagery reveals areas of land cleared for agriculture throughout much of this species' range, however its occurrence in steep, rocky areas (Orlov 1997) may offer some protection from habitat loss associated with agriculture. Despite this species having been successfully bred in captivity (Orlov et al. 2006, Gawor et al. 2012), it may also be threatened by collection from the wild to meet the demand for the international pet trade, as is the case for similarly attractive frog species from the region (Rowley et al. 2010).

Conservation Actions

Conservation Actions
This species is known from a number of protected areas including Tam Dao (Orlov et al. 1997, Inger et al. 1999) and Phong Nha-Ke Bang National Parks (Luu et al. 2014). A number of other additional protected areas are included in parts of the species' predicted range; it is very likely represented 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, the size and trends of its population, and rates of harvest would inform conservation decisions.

Red List Status

Least Concern (LC)

Rationale

Listed as Least Concern as this species is relatively widespread, with an extent of occurrence (EOO) of 244,143 km2, which represents six threat-defined locations.
