Dhanushkodi lagoon is declared a greater flamingo sanctuary to protect migratory birds and local biodiversity
A 5.3 sq km (524.8 ha) lagoon in Dhanushkodi, considered a crucial stopover along the Central Asian Flyway supporting migratory birds, was declared a greater flamingo sanctuary.
Chief Minister M K Stalin made the announcement on June 5 during the World Environment Day celebrations held in Chennai.
"The lagoon also supports large populations of herons, egrets, sandpipers, terns, Kentish plovers, Hanuman plovers, and both greater and lesser flamingos," says Forest Secretary Supriya Sahu. "The area, located at the southern tip of Rameswaram Island and known for its unique landscape of sand dunes, marshes, and mangrove forests, serves as a crucial feeding and roosting ground for these birds.
It also doubles as a nursery for fish, molluscs, and crustaceans that depend on the area for their early development, thereby supporting local fisheries.
"
During the most recent wetland bird census, 10,761 birds were recorded in the area, representing 128 species, both migratory and resident, says Supriya. In addition, the Dhanushkodi beach is an important nesting site for turtles. On the botanical front, the area harbours 47 recorded plant species, including important mangrove types such as Avicennia and Rhizophora.
These mangroves are instrumental in stabilising the coastline, preventing erosion, and buffering the impact of storm surges.
They also offer shelter to marine organisms and birds.
The broader diversity of plants, including herbs, shrubs, and trees, creates a vibrant ecosystem that supports insects, birds, and small mammals. By designating the area as a bird sanctuary, the govt aims to provide formal protection to both resident and migratory bird species and their habitats.
The declaration is also expected to bolster conservation efforts for the region's varied ecosystems, ensuring their long-term ecological integrity.
"We hope to promote public awareness about wetland conservation and the importance of protecting migratory birds," says Supriya. "Responsible tourism practices may also emerge, potentially leading to employment opportunities for local communities while preserving one of Tamil Nadu's most delicate ecological hotspots."
