Distribution and Habitat
Country distribution from AmphibiaWeb's database: Madagascar
Andohahela, Chaines Anosyennes. It occurs between 300-1,500m asl (Raxworthy and Nussbaum 2008).
Life History, Abundance, Activity, and Special Behaviors
An arboreal frog that is only found in pristine forest associate with screw pines (Pandanus). The eggs are laid in leaf axils (often of Pandanus) where the larvae develop (Raxworthy and Nussbaum 2008).
Trends and Threats
This species occurs in Parc National d'Andohahela and Parc National de Marojejy, and probably also in other protected areas. Its taxonomy needs revision (Raxworthy and Nussbaum 2008).
Possible reasons for amphibian decline
General habitat alteration and loss
Habitat modification from deforestation, or logging related activities
Intensified agriculture or grazing
