Site description Bordoibam-Bilmukh is a large freshwater lake that was created during the great earthquake of 1950. It was part of the River Subansiri, which now flows 7 km away from the lake. The Sanctuary is 50 km from Lakhimpur, the district headquarters, and 455 km from Guwahati. A large number of migratory waterfowl are seen in winter while some globally threatened species such as the Spot-billed Pelican Pelecanus philippensis and Lesser Adjutant Leptoptilos javanicus are seen all over the year. The wetland is fringed by tall emergent vegetation, mainly Arundo donax, where the Swamp Francolin Francolinus gularis was not uncommon some years ago. However, the grassland has been destroyed by villagers, so this bird is now rarely seen. The typical aquatic, floating and emergent vegetation of wetlands is seen in this wetland also. In the drying and dried up part, Arundo donax dominates along with sedges. A few Barringtonia acutangula trees are found on the fringes.
