Dudhwa became a tiger reserve in 1979. The area was established in 1958 as a wildlife sanctuary for swamp deer. Thanks to the efforts of Billy Arjan Singh the area was notified as a national park in January 1977.[3] In 1987, the park was declared a tiger reserve and brought under the purview of the Project Tiger . Together with the Kishanpur Wildlife Sanctuary and the Katarniaghat Wildlife Sanctuary it forms the Dudhwa Tiger Reserve.
