The eggs are deposited in leaf-litter, and the adults carry the tadpoles to streams. It is assumed that the species has some immunity to anthropogenic habitat change.
It is an abundant species.
The major threats are deforestation for agricultural development, illegal crops, logging, and human settlement, and pollution resulting from the spraying of illegal crops.
It occurs in a number of protected areas.
