Three streams from Wayanad district's unprotected areas were chosen for the study's purposes. Using the transect method, three species of Nyctibatrachus frogs were surveyed, and the canopy cover over the transects was also noted. According to the study, Nyctibatrachus species are specific to particular microhabitats based on environmental factors such substrate types, canopy cover, altitude, and stream width. The distribution of frogs is affected by several secondary and tertiary parameters, including substrate temperature, ambient temperature, vegetation, and flow rate. The focal species preferred streams with low water velocity, vegetation, and more stony substrates. Acoustic analysis of recorded calls provided the basic call structure of the three night frog species and call types.  The primary cause of the Nyctibatrachus frogs' decline is thought to be clearing of herb and shrub species and other vegetation, proximity to roads, and human settlements.  Frogs that rely on riparian habitat can be saved from local extinction with the active participation of local people and better action plans from the local government to protect riparian habitat.EnglishThesis
