Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2017
Date Assessed: 2016-12-06
Assessor(s): IUCN SSC Amphibian Specialist Group
Reviewer(s): Stuart, S.N.
Contributor(s): Vences, M. & Nussbaum, R.
Facilitator/Compiler(s): Hobin, L.
Justification:
Listed as Least Concern in view of its wide distribution, tolerance of a wide variety of habitats and presumed large population.
Previously published Red List assessments:

Geographic Range [top]

Range Description:This species is broadly distributed in northern, eastern and western Madagascar. The map is very provisional since this is an unresolved species complex. It occurs from 0–1,750 m Asl (Rabearivony et al. 2010).
Countries occurrence:
Native:
Madagascar
Additional data:
Upper elevation limit (metres):1750

Population [top]

Population:It is very common at many sites and the population is believed to be stable.
Current Population Trend:Stable
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:It lives in both intact and degraded rainforest, and is occasionally observed in deforested agricultural areas where some shade and cover remain. It breeds in streams, pools, puddles and rice fields. Knoll et al. (2007) collected larvae from "small and very shallow, slow-flowing streams".
Systems:Terrestrial; Freshwater
Continuing decline in area, extent and/or quality of habitat:Yes
Movement patterns:Not a Migrant

Use and Trade [top]

Use and Trade: There are no records of this species being utilized.

Threats [top]

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).

Conservation Actions [top]

Conservation Actions: Conservation Actions
It occurs in many protected areas including Betampona Strict Nature Reserve (Rosa et al. 2012). 

Research Needed
Further research is essential to fully understand the distribution, origin, type and virulence of Bd lineages found in Madagascar (Bletz et al. 2015).
