Site description This large grassland-wetland complex in Dhemaji district in eastern Assam is located northwest of Dibru-Saikhowa National Park, on the north bank of the Brahmaputra River. The site comprises two reserve forests, Jamjing (8,000 ha) and Sengajan (1,200 ha). It is accessible from Jonai and Dhemaji towns. The main Jamjing beel (300 ha) is outside the Reserve Forest. This poorly known tract has a number of threatened bird species, such as the White-bellied Heron Ardea insignis and Spot-billed Pelican Pelecanus philippensis (Choudhury 1992, 2000). As in Dibru- Saikhowa National Park, Salix swamp forest is a feature of this IBA. Large parts of the area have been encroached upon for seasonal cultivation of paddy and mustard. Tree growth is stunted due to prolonged flooding but in some parts Salix trees are the dominant vegetation. The margins of the wetland are usually covered with reeds such as Arundo donax.
