Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2016
Date Assessed: 2016-05-17

Reviewer(s): Cox, N.A.
Contributor(s): Raxworthy, C.J., Glaw, F., Cadle, J. & Nussbaum, R.
Facilitator/Compiler(s): Hobin, L.
Listed as Least Concern in view of its relatively wide distribution, tolerance of a degree of habitat modification and presumed large population.

Geographic Range [top]

Range Description:This species is broadly distributed in east-central Madagascar from Fierenana south to Andringitra, at 600-1,400 m asl (Andreone et al. 2007).

Population [top]

Population:It is a locally abundant species, however the population trend is unknown.
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:It is a terrestrial rainforest species. It has also been found outside forest in slash-and-burn areas, even at considerable distance from forest. It probably cannot tolerate the complete opening up of the habitat. The eggs are laid on land, and the larvae are washed by rain into streams, where they develop.
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: This species is found in the international pet trade but not at levels that constitute a serious threat.

Threats [top]

Major Threat(s): Although somewhat adaptable, deforestation caused by urbanization, agriculture (including slash and burn agricultural practices) and logging does affect it adversely. It is in the international pet trade, but this is unlikely to be a serious threat. 

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
This species occurs in the Ranomafana, Mantadia and Andringitra National Parks, and in the Pic Ivohibe Special Reserve. It is listed on CITES Appendix II.

Conservation Needed
A carefully regulated trade is the best management option for this species. 

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).
