This dataset contains animal roadkill data (2011-13) from the Valparai Plateau and Anamalai Tiger Reserve, Western Ghats, India. Occurrence records were gathered in the field by researchers of the Nature Conservation Foundation, India. The dataset corresponds to the following publication: Jeganathan, P., Mudappa, D., Kumar, M. A., and Raman, T. R. S. 2018. Seasonal variation in wildlife roadkills in plantations and tropical rainforest in the Anamalai Hills, Western Ghats, India. Current Science 114(3): 619-626.
