As a result mountains plants and animals species have different and unique characteristics. They reveal the entirely different behavior as compare to others wildlife community’s residents in different national park of the country.Himalayan mountain system leaves direct impact on the characteristics of Jim Corbett National Park. As far as the geographical boundary is concerned Corbett’s northern area are marked by the Lesser Himalayan chain which extends from Pakistan, through Jammu and Kashmir, Himachal, Uttaranchal, Nepal, Sikkim, Bhutan, and to Arunachal. The lesser Himalayas are made up of crystalline rocks. These mountains are quite high with an average altitude of 1800 meter. The sal dominated area of Corbett has woody vegetation and rest area vegetation include different species of trees like Oak, Pine and rhododendron.

However, major portion of the park falls in the outer Himalayan or Shiwalik region towards the south. The upper tertiary rocks are exposed towards the Shiwalik range and hence Shiwaliks form the largest ridge across the park, running east to west from Dhangarhi to Kalagarh. These ridges are clothed by sal forests and other associates.
