Introduction
-
Rajaji National Park is situated along the hills and foothills of the Shiwalik ranges in the Himalayan foothills and represents the Shiwalik ecosystem. Combining three sanctuaries, namely Chilla, Motichur and Rajaji, Rajaji National Park is spread over Pauri Garhwal, Dehradun and Saharanpur districts of Uttarakhand. The Motichur and Rajaji sanctuaries are contiguous and are separated from Chilla Sanctuary to the south-east by the Ganges River and the Chilla River. Motichur and Rajaji wildlife sanctuaries lie to the north and south of the Siwalik Ridge and are dissected by many ravines carrying water which descend from the main ridge, becoming broad pebble-/boulder-filled streams in the plains. These streams remain dry for most of the year but become raging torrents during the monsoon. The area is covered with diverse forest types ranging from semi-evergreen to deciduous and from mixed broad-leaved forest to terai grassland. The area has been classified as an Indus-Ganges Monsoon Forest type. Lofty strands of sal dominate in many parts. Rajaji is home to avian species which are found in forested foothills and in open grasslands. It is a location in a transition zone between the temperate western Himalaya and central Himalaya, which enhances the species diversity and consequently the viewing prospects. Rajaji's checklist has about 400 birds species and includes birds like the greater scaup, white-naped woodpecker, great hornbill, black-bellied tern, Pallas's fish eagle, northern goshawk, black-necked stork, yellow-billed blue magpie, scaly thrush, snowy-browed flycatcher, rusty-flanked treecreeper, pale-footed bush warbler, Tytler’s leaf warbler, green avadavat and reed bunting.
