The water bodies and mangroves of Kumana provide particularly a very important habitat for birds. Block II of the park was established in December 1969 and Block I in January 1970. The total extent of the park is 18,149 hectares with Block I consisting of 17,863 and Block II consisting only 265.3. The main feature this park is renowned for is the 200 hectare mangrove swamp which teams with nesting birds in May-June. It is surrounded by plains and jungle. There are saline large lagoons along the coast, often surrounded by extensive plains. The vegetation is mostly semi-arid thorn scrub with large areas of dense forest. DWLC is in the process of re building the bungalows at this park. The camp sites have to be pre booked. There are many places to stay over night in Arugambay/Pottuwil.
