Frog occurrence records from rainforest fragments of the Valparai Plateau and Anamalai Tiger Reserve, Western Ghats, India

Frogs were sampled using belt transects (25 m x 4 m) placed in two habitat strata — terrestrial rainforest interior and stream — across 10 rainforest fragments and three control sites in the ATR. Sampling was conducted during the south-west monsoon season (June–September 2018) when anurans are most vocal and active for breeding.

A total of 13 sites were surveyed: 10 rainforest fragments of varying size classes (small, medium, large) within the plantation landscape and 3 control sites within the ATR. The dataset contains 143 occurrence records representing 33 anuran species from 8 families across all sites.
