This Site, locally known as “Chitrangudi Kanmoli”, is located in the village of Chitrangudi, adjacent to Kanjirankulam Bird Sanctuary in Ramanathapuram district. The wetland has been a protected area since 1989 and is also classed as an Important Bird and Biodiversity Area (IBA). There are 50 bird species found, including four near-threatened species. The Sanctuary is an important breeding ground for wintering birds such as spot-billed pelican (Pelecanus philippensis), painted stork (Mycteria leucocephala), little egret (Egretta garzetta) and grey heron (Ardea cinerea). It is also rich in medicinal plants such as holy basil (Ocimum sanctum) and flame lily (Gloriosa superba), the State flower of Tamil Nadu. Due to its rich biodiversity, the sanctuary is frequently visited by nature enthusiasts and birdwatchers. Despite being a hotspot for birds, the wetland water occasionally dries as its major sources are rainfall and run-off water. However, this feature also makes the wetland a buffering area during heavy rainfall and a sink for sediments and nutrients during flooding. The regional forest department undertakes regulation activities during the summer season to maintain the water level of the lake.
