Trends and Threats
Species is listed as data deficient because of continuing uncertainties as to its extent of occurrence, status and ecological requirements. Its forest habitat is receding due to subsistence agriculture, timber extraction, charcoal manufacture, invasive spread of eucalyptus, livestock grazing, fires and expanding human settlements. It occurs in the R�serve Sp�ciale d�Ambohitantely, which is poorly managed, and Parc National d'Andohahela, which is well managed (Nussbaum and Vallan 2008).

Possible reasons for amphibian decline

Habitat modification from deforestation, or logging related activities
Intensified agriculture or grazing
Urbanization
Subtle changes to necessary specialized habitat
