DEHRADUN: Wildlife Institute of India, Dehradun will be conducting ecological survey of six major rivers of India — Mahanadi, Periyar, Godavari, Kaveri, Narmada and Barak. The survey will be conducted under National River Conservation Plan to assess ecological status of the rivers and ecosystem around these rivers.
