Mahavidyalaya Kavathe Mahankal, Sangli (M.S) India Email: [email protected] Abstract: The Sanctuary area is home to several species, rich endemic flora and harbors different species of fauna. Amphibians are one of the most ubiquitous groups of predators in the animal kingdom commonly found in all terrestrial and many aquatic ecosystems. Baveli and Talegaon region is the part of Northern Western Ghats of Maharashtra. So far no body has worked out or studied the amphibian Diversity from Baveli, Talegaon region of Radhanagari Wildlife Sanctuary and hence we have decide to explore the amphibian diversity from this area. Most of the area is dense semi-evergreen forest with a wide range of flora. The area prevails humid and moderate climate and heavy rainfall This high diversity of habitats responsible for amphibian diversity. For the present study the survey of amphibians was carried out during rainy season (late May to late October). The presence of various species of frogs were noted on the bases of actual sighting, presence of egg clusters (for same species), on their calls. The specimens were obtained along the streams and through patches of forest during day light and early night hours. The most distinct feature of this area is the presence of numerous barons rocky and laetrile plateau called as sadas. Sodas provide good breeding ground for Bufo koynnayensis toads. Sadas are with less perennial vegetation and over hanging clips on the edges and numerous fallen boundaries with dense thorny vegetation .Amphibians from family bufonidae, ranidae, microhylidae ,rhacophoridae and caecillidae were reported.
