Site description This complex covers Dibru-Saikhowa National Park, Poba Reserve Forest, Kobo chapori (river islands) proposed reserve forest, Amarpur chapori, Maguri and Motapung beel (lake), and the adjacent riverine tract of the Brahmaputra and Lohit rivers. The Dibru-Saikhowa NP proper covers 34,000 ha in the districts of Tinsukia and Dibrugarh in eastern Assam. It is 13 km north of Tinsukia town. It is also a Biosphere Reserve. The area is known as a major haunt of the globally threatened White-winged Duck Cairina scutulata, Black-breasted Parrotbill Paradoxornis flavirostris and Marsh Babbler Pellorneum palustre. In 1986, the Government of Assam declared Dibru and Saikhowa Reserve Forests as Dibru-Saikhowa Wildlife Sanctuary, covering 64,000 ha which also included Amarpur chapori and the adjacent riverine tract of the Brahmaputra and Lohit rivers. Subsequently, the area was upgraded to a national park. However, at the time of final notification as a sanctuary and as well as a national park, only the reserve forest areas were included. Maguri and Motapung beels in Tinsukia district, although very important for the conservation of waterfowl, are outside. Similarly, Poba and Kobo, important biodiversity sites, are located north of the Park and are in Dhemaji disrict. We have included all these adjacent sites in one IBA. Dibru-Saikhowa has the largest salix swamp forest in northeastern India. Tropical Moist Deciduous, Tropical Semi-evergreen, Evergreen Forests and grassland forms the main habitat type. The original vegetation of the Park was tropical rainforest, but a large part sank by a few meters during the earthquake in 1950, causing significant geomorphological changes. Due to regular flooding, the rainforest gradually gave way to deciduous forest and swamps (Choudhury 1998). The relatively remote Amarpur area, on the northern side of the Brahmaputra river, not included in the Park but is a part of the wider Dibru-Saikhowa Biosphere Reserve, has significant areas of tall grass, which are largely absent in the other areas of the Park. The Amarpur peninsula within the Biosphere Reserve covers about 3,000 ha. It is generally low-lying and much of it is flooded during the monsoon season (Allen 2002).
