|Red List Category & Criteria:||Least Concern ver 3.1|
|Assessor(s):||IUCN SSC Amphibian Specialist Group|
|Contributor(s):||Vallan, D. & Vences, M.|
Listed as Least Concern in view of its wide distribution, tolerance of a broad range of habitats and presumed large population.
|Previously published Red List assessments:|
|Range Description:||This species is widely distributed in east-central Madagascar at 1,000-2,000 m Asl, from Ambohitantely south to south of Ranomafana.|
|Range Map:||Click here to open the map viewer and explore range.|
|Population:||It is a common species and the population is believed to be stable.|
|Current Population Trend:||Stable|
|Habitat and Ecology:||It lives near seeps and tiny amounts of slow-flowing water in open areas, rice paddies and other agricultural areas, forest edge and inside montane forest. It has been found in gardens in Antananarivo. The egg deposition side is unknown, but the tadpoles have been found in seeps.|
|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.|
|Major Threat(s):||Deforestation appears to be affecting some populations, but not others, presumably reflecting the fact that this is a complex of several species. Therefore, as currently understood, this species is generally not significantly threatened by habitat loss. 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 Ranomafana National Park and Ambohitantely Special Reserve.
Further research is essential to fully understand the distribution, origin, type and virulence of Bd lineages found in Madagascar (Bletz et al. 2015).
