Listed as Least Concern in view of its relatively wide distribution and presumed large population.
|Previously published Red List assessments:|
|Range Description:||This species is known from several areas in northern and northwestern Madagascar, from Fôret d’Ambre Special Reserve and Montagne d'Ambre National Park (Raxworthy and Nussbaum 1994, D'Cruze et al. 2008) south to near Maevatenana, including forest fragments in the Tsarakibany area (Durkin et al. 2011). It is likely to occur more widely than currently known. It has been recorded at 200-1,150 m asl.|
|Range Map:||Click here to open the map viewer and explore range.|
|Population:||It is a locally abundant species. Due to ongoing decline in the extent and quality of habitat, the population is suspected to be decreasing.|
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||This species inhabits pristine rainforest, along streams and rivers on the forest floor. But the species also shows a degree of resilience as it has also been recorded in highly fragmented forests, and degraded primary and secondary forests (M.D. Scherz pers. comm. March 2016). Its egg deposition site is not known, but tadpoles live in streams.|
|Continuing decline in area, extent and/or quality of habitat:||Yes|
|Movement patterns:||Not a Migrant|
|Use and Trade:||There are no records of this species being utilized.|
Its forest habitat is receding due to subsistence agriculture, timber extraction, charcoal manufacture, and invasive spread of eucalyptus, 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).
This species occurs in Fôret d’Ambre Special Reserve, Montagne d'Ambre National Park (D'Cruze et al. 2008), Tsaratanana Strict Nature Reserve, and Scherz et al. recorded it in the Mahimborondro corridor south of Tsaratanana (a proposed protected area).
Additional work is required on the species' population size, distribution and trends, and its ecological requirements. Further research is also essential to fully understand the distribution, origin, type and virulence of Bd lineages found in Madagascar (Bletz et al. 2015).
