Population [top]

Population:	It is less common than other members of the family Sooglossidae.
Population Trend:	Unknown

Habitat and Ecology [top]

Habitat and Ecology:	It is restricted to relatively undisturbed habitat in wet rocky areas along streams or dry streambeds. The recent low-altitude records were from secondary forest, but it shows a strong preference for higher altitudes and undisturbed habitats. It breeds by direct development, the eggs being laid among rocks.
Systems:	Terrestrial; Freshwater

Threats [top]

Major Threat(s):	The main threat is habitat degradation, mainly due to fire and invasive species, but it is not thought to be seriously threatened in its higher altitude habitat. It might be inherently at risk because of its small range.
