Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2016
Date Assessed: 2016-02-24

Reviewer(s): Luedtke, J.
Contributor(s): Crottini, A., Andreone, F., Vences, M. & Nussbaum, R.

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 known from several high-elevation localities in central Madagascar, including Andringitra, Ankaratra, Mandraka, Itremo, Col des Tapias and Ambohitantely. It occurs at 1,200-1,800 m asl, possibly higher.

Population [top]

Population:It is locally very abundant. However due to ongoing declines in the extent and quality of habitat, the population is suspected to be decreasing.
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:It is a species of high-elevation rainforest. It also survives in degraded areas and open habitats, providing that some trees remain. It needs fast-flowing, clean streams for breeding and so is not found in villages.
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): Its forest habitat is receding due to subsistence agriculture, timber extraction, charcoal manufacture, and invasive spread of eucalyptus, livestock grazing, fire and expanding human settlements. It is probably also adversely affected by the pollution of breeding streams.

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 Andringitra National Park, Ambohitantely Special Reserve.

It may also occur in the newly created Ankarana Massif Reserve established by the Madagascan conservation organization Association Vondrona Ivon’ny Fampandrosoanavif (VIF) and with the support of its U.S. partners Amphibian Survival Alliance, Global Wildlife Conservation and Rainforest Trust (Moore 2015). VIF manage the reserve through forest guard units assembled in collaboration with local communities. These units regularly patrol the reserve to stop illegal logging and have effectively decreased logging rates. In addition, local communities are engaged in reforestation efforts intended to improve habitat within the Reserve and amphibian populations on the Massif are subject to ongoing monitoring (A. Crottini pers. comm. February 2016).

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