Assessment Information [top]

Red List Category & Criteria: Endangered B1ab(iii) ver 3.1
Year Published: 2016
Date Assessed: 2015-11-25
Assessor(s): IUCN SSC Amphibian Specialist Group
Reviewer(s): Stuart, S.N.
Contributor(s): Andreone, F., Scherz, D. & Nussbaum, R.
Facilitator/Compiler(s): Hobin, L.
Justification:
Listed as Endangered because its extent of occurrence (EOO) is 3,787 km2, it occurs in three threat-defined locations and there is ongoing decline in the extent and quality of habitat, despite some protection provided by Marojejy National Park and Anjanaharibe-Sud Special Reserve.

Geographic Range [top]

Range Description:This species is known from the Anjanaharibe-Sud Special Reserve (Andreone, 1996), Ambolokopatrika and Tsararano (Andreone et al. 2000), and Marojejy National Park (Glaw & Vences 2007) in north-eastern Madagascar, between 800-1,000 m asl. It is known from three threat-defined locations and its extent of occurrence (EOO) is 3,787 km2.

Population [top]

Population:It is common in its range. However due to ongoing decline in the extent and quality of habitat, the population is suspected to be decreasing.
Current Population Trend:Decreasing
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:It is a species of pristine rainforest, and of slightly degraded habitats (but these are always close to good forest). It breeds in streams, presumably through larval development.
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, invasive spread of eucalyptus, livestock grazing, and expanding human settlements. These threats occur right up to the edges of the protected areas.

Intensive illegal wood extraction of rosewood species within Marojejy National Park that followed the 2009 political crisis of Madagascar caused concerns for the survival of rainforest–restricted species, such as this one. However, while illegal rosewood logging has probably ceased, wood extraction currently taking place in the Park seems to occur at lower elevations and is not thought to have reached elevations where this species has been recorded; along the boundaries of Marojejy deforestation is taking place to clear land for agriculture (F. Glaw pers. comm. November 2015).

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
The species is known from Anjanaharibe-Sud Special Reserve and Marojejy National Park. Marojejy is currently relatively well-protected, and Anjanaharibe-Sud Special Reserve also benefits from a relatively good level of protection (F. Glaw pers. comm. Nov. 2014). 

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

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).
