|Red List Category & Criteria:||Least Concern ver 3.1|
|Assessor(s):||IUCN SSC Amphibian Specialist Group|
|Contributor(s):||Vallan, D. & Glaw, F.|
Listed as Least Concern in view of its relatively wide distribution and presumed large population.
|Previously published Red List assessments:|
|Range Description:||This species is broadly distributed in east-central Madagascar, from Ambatovaky south to Befotaka-Midongy (Bora et al. 2007). It has been recorded at 500-1,100 m asl.|
|Range Map:||Click here to open the map viewer and explore range.|
|Population:||It is a locally common species. Due to ongoing decline in the extent and quality of habitat, the population is suspected to be decreasing.|
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||This species lives in pristine rainforest, and has once been found in secondary habitats next to forest. The eggs are laid on leaves above streams, into which the larvae fall and develop.|
|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.|
Its forest habitat is receding due to subsistence agriculture, timber extraction, charcoal manufacture, and 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).
This species occurs in several protected areas including Befotaka-Midongy National Park (Bora et al. 2007).
Further research is also essential to fully understand the distribution, origin, type and virulence of Bd lineages found in Madagascar (Bletz et al. 2015).
