Midongy du Sud, Vevembe, Vohiparara, Vondrozo. It occurs between 700-1050m asl in primary and secondary rainforest and sometimes in disturbed habitats (Glaw and Cadle 2008).

Life History, Abundance, Activity, and Special Behaviors
Habits: Similar to G. boulengeri. Often heard also from secondary vegetation far from any forest, e.g., in the village of Vondrozo.

Calls: A relatively slow series of 40-50 unharmonious notes.

Breeding takes place by direct development (Glaw and Cadle 2008).

Trends and Threats
This species is threatened by the loss and degradation of its forest habitat due to subsistence agriculture, timber extraction, charcoal manufacture, invasive spread of eucalyptus, livestock grazing and expanding human settlements. It occurs in Parc National de Ranomafana, the Réserve Spéciale du Pic Ivohibe, and Parc National de Midongy-du-Sud (Glaw and Cadle 2008).

Possible reasons for amphibian decline

General habitat alteration and loss
Habitat modification from deforestation, or logging related activities
Intensified agriculture or grazing
Habitat fragmentation
