The Desert National Park is located 45 km west of the Jaisalmer city in the west Indian state of Rajasthan close to the India- Pakistan border. Spread over an area in excess of 3150 sq km, this is probably the largest park of India. Rajasthan Desert National Sanctuary was set up in 1980. The desert sanctuary being a fragile ecosystem has its own flora and fauna. Sand-dunes, both fixed and shifting, low rock-faces, grasslands and scrublands, characterize this park where the greatest need is for water. The topography of the park comprises of craggy rocks, compact salt lake bottoms and vast sand dunes, which form about 20% of the Park. There are three main lakes in this sanctuary - Rajbaugh Lake, Milak Talao Lake and Padam Talao Lake. These lakes are the major watering holes for the inhabitants of the national park. As the desert only supports a few type of small grasses, shrubs and xerophytic trees, the leaf cover is limited and not suitable for large herbivorous, camel being an exception. Vast tracts are encrusted with sewan grass, and the aak shrub and khair, khejra and rohira trees are widespread, but sand dominates every scene. Even so, many creatures have adapted to this harsh, inhospitable terrain.
