Listed as Near Threatened because, despite an extent of occurrence (EOO) of 13,771 km2 and ongoing decline in the quality and extent of forest habitat within its range. the species appears not to be in decline thanks to its resilience and adaptability to a certain level of degraded habitat. The species is close to qualifying for Vulnerable B1.

Use and Trade [top]

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

Threats [top]

Major Threat(s): This species is threatened by the loss and degradation of its forest habitat due to subsistence agriculture, timber extraction, charcoal manufacture, 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).

Conservation Actions [top]

Conservation Actions: Conservation Actions
It occurs in Andohahela and Befotaka-Midongy National Parks.

Conservation Needed
Improved protection and management of forests throughout the region is required, including within the boundaries of protected areas.

Research NeededFurther 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).
