Dudhwa National Park opens for public after monsoon closure. This national park was established in 1958 as a wildlife sanctuary and the area was notified as a national park in January 1977. In 1988, the park was declared as a tiger reserve, and forms the Dudhwa Tiger Reserve together with the Kishanpur Wildlife Sanctuary. Dudhwa National Park is home to one of the finest Sal forests in India, some of these trees are more than 150 years old and over 70 feet tall. Some rare species inhabit the park. Hispid hare, earlier thought to have become extinct, was rediscovered here in 1984. In the mid 1980s, Indian rhinoceros was reintroduced into Dudhwa from Assam and Nepal.
