Rajaji represents floral elements of both the Himalayan and the Upper Gangetic Plains. Owing to its location between both these bio- geographic regions, it is home to one of the most diverse ranges of wildlife habitats in the country. The eight major forests types including the Western Gangetic Moist, Northern Dry Deciduous and Khair-Sissoo forests in the southern slopes, the Low Alluvial Savannah Woodlands in the southern margins of the reserve, and the Shiwalik Chir-Pine forests in the higher reaches of the hills makes this area rich of bio diversity.
