"Rhacophorus margaritifer" occurs in both lowland and montane forests, including in disturbed forests, at elevations of above sea level. Breeding takes place in streams. This species is threatened by habitat loss associated with smallholder farming and subsistence wood collecting. Also "Batrachochytrium dendrobatidis" has been detected in it, although this  is not known to be associated with declines. It is present in the pet trade, with an annual quota of 900 specimens. It occurs in several protected areas.
