Answer: Tamil Nadu
Notes: The Tamil Nadu government plans to build a high-level bridge to protect the Pallikaranai Marshland, a freshwater and saline wetland 20 km south of Chennai. As one of Chennai's last natural wetlands, it serves as an aquatic buffer, draining 250 sq.km through Okkiyam Madavu and Kovalam Creek into the Bay of Bengal. A Ramsar site, it supports diverse species including 115 bird species, Russell’s viper, and the glossy ibis.
