Listed as Least Concern because it has a wide distribution, it occurs in many protected areas and it has a presumed large population.
|Previously published Red List assessments:|
|Range Description:||This species was previously only known with certainty from the type locality near Andasibe in east-central Madagascar. Tadpoles have now been found in Analamazaotra and Mantadia in the Andasibe area (Raharivololoniaina et al., 2006). It is also known from Befotaka-Midongy National Park in southeastern Madagascar (Bora et al., 2007), in Masoala in northeastern Madagascar (Glaw and Vences, 2007), and in Sorata in northern Madagascar (F. Glaw unpubl. data). It is thought to occur more widely, and there is an unconfirmed record from Pic d'Ivohibe (D. Edmonds unpubl. data) and one from a stream beside a road near Ampandrana, between Antsohihy and Bealanana (F. Glaw unpubl. data) [which is not mapped here]. Its altitudinal range is 690-900 m asl. |
Records from Ranomafana and Zahamena in eastern Madagascar could belong to this species or to Boophis albipunctatus.

|Population:||This species is moderately common where it has been found. However due to ongoing declines in the extent and quality of habitat, the population is suspected to be decreasing.|
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||It is restricted to pristine rainforest, where it breeds in streams by larval development. Males call at night from vegetation along streams, usually from high perches of more than 3m off the ground (Glaw and Vences, 2007).|
|Continuing decline in area, extent and/or quality of habitat:||Yes|
|Movement patterns:||Not a Migrant|
|Use and Trade:||There are no records for this species being utilized.|
Its forest habitat is receding due to subsistence agriculture, timber extraction, charcoal manufacture, invasive spread of eucalyptus, livestock grazing, and expanding human settlements. It might also be impacted by pollution of 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).
This species occurs many protected areas including in Analamazaotra Special Reserve and Befotaka-Midongy National Park. There is an unconfirmed record from Pic d'Ivohibe Special Reserve (D. Edmonds unpubl. data).
Further research is also essential to fully understand the distribution, origin, type and virulence of Bd lineages found in Madagascar (Bletz et al., 2015).
