History of the Orang National Park

History of the ONP dates back to the year 1900. The sanctuary area was inhabited by local tribes till the year 1900. British government declared the sanctuary area as Orang Game Reserve on May 31, 1915. Later the Assam state forest department considered orang game reserve for Project Tiger. Government of Assam established the Orang Wildlife Sanctuary in the year 1985 to protect the wildlife present in the sanctuary area. This park was renamed as Rajiv Gandhi Wildlife Sanctuary in the year 1992, which was reversed due to public pressure against renaming. Finally, the sanctuary was upgraded to Orang National Park on 13th April 1999 to protect different endangered and critically endangered species of wild animals and birds in India.
