Jim Corbett National Park is the oldest national park in India and was established in 1936 as Hailey National Park to protect the endangered Bengal tiger. It is located in Nainital district and Pauri Garhwal district of Uttarakhand and was named after Jim Corbett, a well-known hunter and naturalist. The park was the first to come under the Project Tiger initiative. The park has sub-Himalayan belt geographical and ecological characteristics. An ecotourism destination, it contains 488 different species of plants and a diverse variety of fauna. The increase in tourist activities, among other problems, continues to present a serious challenge to the park’s ecological balance. Corbett has been a haunt for tourists and wildlife lovers for a long time. Tourism activity is only allowed in selected areas of Corbett Tiger Reserve so that people get an opportunity to see its landscape and wildlife. In recent years the number of people coming here has increased dramatically. Presently, every season more than 70,000 visitors come to the park. Corbett National Park comprises 520.8 km2 (201.1 sq. mi) area of hills, riverine belts, marshy depressions, grasslands and a large lake. The elevation ranges from 1,300 to 4,000 ft. (400 to 1,220 m). Winter nights are cold but the days are bright and sunny. It rains from July to September. Dense moist deciduous forest mainly consists of sal, haldu, peepal, rohini and mango trees. Forest covers almost 73% of the park, 10% of the area consists of grasslands. It houses around 110 tree species, 50 species of mammals, 580 bird species and 25 reptile species.
