The Dudhwa National Park is a national park in the Terai of Uttar Pradesh, India, and covers an area of 490.3 km2 (189.3 sq mi), with a buffer zone of 190 km2 (73 sq mi). It is part of the Dudhwa Tiger Reserve. It represents one of the few remaining examples of a highly diverse and productive Terai ecosystem, supporting a large number of endangered species, obligate species of tall wet grasslands
and species of restricted distribution. 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.] 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.
