|Red List Category & Criteria:||Endangered B1ab(iii) ver 3.1|
|Assessor(s):||IUCN SSC Amphibian Specialist Group|
|Contributor(s):||Andreone, F., Glaw, F. & Vences, M.|
Listed as Endangered because its extent of occurrence is 2,367 km2, its distribution is severely fragmented, it occurs in two threat-defined locations, and there is continuing decline in the extent and quality of its forest habitat in northern Madagascar.
|Previously published Red List assessments:|
|Range Description:||This species is known from Nosy Be Island and from Sahamalaza Peninsula (Berara) on the mainland of northwestern Madagascar. It occurs from sea level up to 200 m asl and is likely to occur more widely, but its current extent of occurrence (EOO) is 2,367 km2.|
|Range Map:||Click here to open the map viewer and explore range.|
|Population:||It is a locally abundant species, but its population is severely fragmented because there is no dispersal between the mainland and Nosy Be. 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 arboreal species inhabits primary and secondary rainforest, and also occurs in tree plantations, gallery forest, and dense secondary vegetation, but always along streams in which breeding takes place by larval 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.|
Its forest habitat is receding due to subsistence agriculture, including livestock grazing, timber extraction, charcoal manufacture, fire, and expanding human settlements. It is probably also impacted by water pollution on Nosy Be and the drying up of streams as a result of water abstraction.
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 Réserve Naturelle Intégrale de Lokobe on Nosy Be, where it receives very good protection, and the Sahamalaza National Park.
Further protection of forest habitats in the region is required.
Further research is required to clarify the species' distribution, population size and trends, and is essential to fully understand the distribution, origin, type and virulence of Bd lineages found in Madagascar (Bletz et al. 2015).
