Koonthakulam BIRD SANCTUARY

Koonthankulam Bird Sanctuary or Kunthankulam is an important human-made wetland in the state of Tamil Nadu. Spreading over 72.04 ha, the wetland is located near Koonthankulam village in Nanguneri Taluk of Tirunelveli district. The wetland was declared as a bird sanctuary in 1994 and comes under the jurisdiction of Tamil Nadu Water resources department (PWD) and Tamil Nadu Forest Department, Tirunelveli district. The inland tank was built few centuries ago, interconnected by canals that bring water from the rivers originating in the Western Ghats. These rivers and tanks support rich social and cultural heritage and economically support agriculture. It irrigates about 190 acres of paddy. While socio-economic and cultural significance exist, very little is known about their ecological importance. The site experiences tropical humid climate, receiving water only through seasonal rainfall ranging from 750-850 mm. The major sources of water for the wetland is rainfall, groundwater, surrounding runoff from catchment and Manimutharu Dam. The wetlands consist in the form of irrigation tanks, interconnected by an ancient network of canals, and fed by the rivers originating from the Western Ghats. These irrigation tanks have socio-economic and cultural significance.
