|Red List Category & Criteria:||Vulnerable B1ab(iii) ver 3.1|
|Assessor(s):||IUCN SSC Amphibian Specialist Group|
|Contributor(s):||Raxworthy, C.J., Glaw, F. & Vences, M.|
Listed as Vulnerable because its extent of occurrence is 16,404 km2, it occurs in fewer than 10 threat-defined locations, there in ongoing decline in the quality and extent of its habitat, and it occurs several small, widely separated subpopulations.
|Previously published Red List assessments:|
|Range Description:||This species is known only from southeastern Madagascar, from Andringitra south to Andohahela, between 600-1,000 m asl. It occurs in fewer than 10 threat-defined locations, and its extent of occurrence (EOO) is 16,404 km2.|
|Range Map:||Click here to open the map viewer and explore range.|
|Population:||It is a rare species with a patchy distribution. Due to ongoing declines in the extent and quality of habitat, the population is suspected to be decreasing.|
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||This is a species of pristine rainforest, which does not live in altered habitats. It is found on the forest floor and is particularly associated with bamboo. Breeding is presumed to be by direct development.|
|Continuing decline in area, extent and/or quality of habitat:||Yes|
|Movement patterns:||Not a Migrant|
|Use and Trade:||There are no records of this species being utilized.|
It is threatened by the loss and degradation of its forest habitat due to subsistence agriculture, timber extraction, charcoal manufacture, invasive spread of eucalyptus, livestock grazing and expanding human settlements.
Species in this genus have tested positive for Batrachochytrium dendrobatidis (Bd), however currently there have been no negative effects observed within amphibian populations in Madagascar suggesting the Bd strain has a low virulence level (Bletz et al., 2015).
It occurs in the Kalambatritra Special Reserve, Andohahela National Park and Andringitra National Park.
Further research is essential to fully understand the distribution, origin, type and virulence of Bd lineages found in Madagascar (Bletz et al., 2015).
