Listed as Endangered because its extent of occurrence is approximately 800 km2, it is known from only two locations, and there is likely to be continuing decline in the extent and quality of its bamboo forest habitat in southeastern Madagascar.

Geographic Range [top]

Range Description:This species has a very small range in south-eastern Madagascar, in the Anosy Mountains, at 1,900 m asl, close to the mountain summit at 1,959 m asl. It has recently been reported from Andohahela, a national park within the Anosy Mountains, at a site 1,548 m asl (Vences et al. 2010). Its extent of occurrence is estimated to be 795 km² and it occurs at two locations, defined by human pressures from agriculture and exploitation of forest resources.

Population [top]

Population:It is uncommon in Andohahela National Park (Vences et al. 2010).
Current Population Trend:Unknown
Additional data:
Population severely fragmented:Unknown

Habitat and Ecology [top]

Habitat and Ecology:It is apparently confined to bamboo forests at high elevations, and presumably breeds in water filled cavities in bamboo and has a non-feeding larval form.
Systems:Terrestrial; Freshwater

Use and Trade [top]

Use and Trade:

There are no reports of this species being utilized.

Threats [top]

Major Threat(s): The main threat is likely to be habitat loss due to subsistence agriculture, timber extraction, charcoal manufacture, spread of invasive eucalyptus, livestock grazing, fires, and expanding human settlements. However, as a mountain-top species, it could also be a risk from global warming.

Conservation Actions [top]

Conservation Actions: The habitat of the Anosy Mountains is in urgent need of protection. This frog is known from a locality within Andohahela National Park, but appears not to be common there (Vences et al. 2010). However, this site is not well protected, and is under pressure from agricultural conversion and logging. Further research is needed on this species' distribution, population status, life history and threats.
