To record anuran diversity, a study was conducted at eight temporary breeding sites in and around Dharwad (15°26’N 74°58’E), Karnataka, India. For sampling, anuran population, we have used acoustics and visual encounter method. A total of 12 species belonging to four families and eight genera were recorded. The diversity, abundance and relative abundance was highest at site B5 and it was lowest at site B2. Mirohyla ornata was the most abundant species found in all the eight study sites. Hopalobatrachus crassus was the least abundant species. In the pair-wise comparison, beta diversity was highest between the sites B5 and B8 and it was least between the sites B2 and B8. The Jaccard's similarity index was highest between sites B1 and B3, and the minimum similarity was observed at site B8. The study provides a baseline data on anuran assemblage that can be used for evaluating the amphibian status and taking conservation measures to protect the habitat and the species.
