The potential of the Sultan National Park and Bird Sanctuary to become a bird preserve was first identified by an enthusiastic bird watcher, Mr. Peter Jackson. He then convinced the then Prime Minister of India, Ms. Indira Gandhi, about the need for giving protection to this area and became successful in convincing. The Government of India declared the area covering 359 acres as a Bird Sanctuary in the year 1971 and it was again upgraded to the status of National Park in 1989 by the State Government of Haryana
After the up gradation, the Department of Wild Life Preservation, Haryana has so far carried out a number of development works like construction of mounds, widening of paths, etc. in the bird sanctuary. Apart from that, an education and interpretation center, and a library have also been established within the bird sanctuary.
