The Corbett National Park is an excellent and largely inviolate specimen of the rich sal and mixed woodland that spans the outer Himalayas. Because of its rich biogeographic diversity, the Park is a natural haven for the flora and fauna of the plains, the submountainous regions and high altitude areas.
At the lower level are winding strips of alluvial grasslands or chaurs (beloved to many species of deer) crossed by numerous water courses. The lifeline of the Park is the sparkling Ramganga river which provides safe harbour to mahaseer fish, crocodile and otter. Stately stands of sal and diverse mixed forest cover hills and valleys, fodder and foliage for large herds of elephants. Sharp spurs in the terrain make it an idyllic habitat for shy species like the tiger.
The incredible variety of mammals, birds and vegetation at Corbett reveals one of the healthiest 'food chains' this side of the world. Almost all the major groups of animals known to exist in the Himalayan Terai and the Bhabar foothills region are found here. The abundance of the prey species determines the presence and survival of the predators. As the abundance of diverse vegetation supports myriad species, from avian to mammal.
