The Vedanthangal freshwater lake attracts water birds, and the area was protected by the local people, who benefited from the manure-rich water from the lake. The
guano of the birds increased the agriculture yield of the surrounding fields. Vedanthangal literally means the 'hamlet of the hunter' in
Tamil language. Towards the end of the 18th century, locals complained to the
District Collector of
Chingleput district about the British soldiers shooting the birds and obtained a cowle (a written acceptance) from the collector to protect the birds. Due to its ecological importance, the
British Government initiated further steps to develop it into a bird sanctuary in 1798. Several accounts of the area being a breeding place for birds were published in the 19th century. In the mid 19th century, the collector of Chingleput ordered it to be established as a protected area. The surrounding wetland was declared as reserve area as per the
Madras Forest Act, 1882 on 4 June 1962. Subsequently, the surrounding zone were declared as part of the sanctuary as per the
Wildlife Protection Act, 1972 in 1996 and the final notification was issued on 8 July 1998. == Description ==
