. It is semi-aquatic and semi- arboreal species that is active by day and night. It is a locally common frog where suitable habitat exists. However, it is threatened by clear-cutting of lowland tropical rainforest for oil palm plantations, small holder agriculture, and wood extraction. Use of insecticides might also be a threat. Its range overlaps with some protected areas.
