Site description The Manas National Park, a world heritage site, is located in western Assam on the international border with Bhutan. The most well known of the wildlife reserves of northeast India and second only to Kaziranga, it was earlier called the North Kamrup Wildlife Sanctuary. The river Manas with its distributaries, the Beki and Hakua, flows through the Park. Other smaller streams include Jongrong, Gyati and Garuchara. Known for its scenic beauty, Manas is also home to a number of globally threatened birds and mammals. The Park has now the only viable population of the Critically Endangered Pigmy Hog Sus salvanius. An added advantage to Manas is the presence of the 102,300 ha Royal Manas National Park across the border in Bhutan. For many species, it is a large contiguous wilderness area. The terrain in Manas is mostly flat, gently sloping plain typical of bhabar and terai. Towards the north, small hilly promontories of the Bhutan Himalaya can be seen. Approximately half of Manas is savanna grassland, while the rest is Moist Deciduous and Semievergreen forest. There are no large beels (waterbody), but small beels and pools occur in the southern areas. The three main types of vegetation are: i) Tropical Semi-evergreen forests in the northern part of sanctuary; ii) Tropical Moist Deciduous Forests (the most common type); and iii) extensive alluvial grasslands in the western part of the National Park, comprising many grass species, and a variety of tree and shrub species (e.g. Dillenia pentagyna, Phyllanthus emblica, Bombax ceiba, and species of Clerodendrum, Leea, Grewia, Premna and Mussaenda). There is also a considerable variety of aquatic flora along riverbanks and in the numerous pools (Jain and Sastry 1983). Drier deciduous forests represent early stages in succession and are replaced by Moist Deciduous forests away from watercourses, which, in turn, are succeeded by Tropical Semi-evergreen climax forest. Grasslands cover about 50% of the Sanctuary. Some 393 species of dicotyledons, including 197 trees, and 98 species of monocotyledons have been identified.
