Abstract :

The Nilgiri Biosphere Reserve (NBR) is the home for many endemic species of Western Ghats. Amphibians within Western Ghats and Nilgiri Biosphere Reserve show very high level of endemism especially in the genus Raorchestes. The genus Raorchestes is shrub frog belonged to the family Rhacophoridae , and the class Amphibia. Published information on the Herpetofauna particularly about amphibians of NBR is scanty, There is no detailed study on the ecology of the bush frogs. Hence it was decided to study the ecology, current taxonomic positions, habit and habitat and distribution pattern of bush frogs. Four different localities were selected for this study in and around Udhagamandalam. In each locality visual encounter survey method was used to collect data on bush frogs. During the study period, three species of Raorchestes were recorded which included R. tinniens, R. signatus and R. thodai. Raorchestes mostly recorded during the rainy season under bushes and other vegetations.
