Site description This site includes Pani-Dihing Bird Sanctuary (3,393 ha) and its environs (600 ha), including Phokolai and Dorou beels. Situated 17 km north of Sibsagar town, the district headquarters, this large wetland complex lies on the south bank of River Brahmaputra, near its confluence with the tributary Disang. The terrain is flat, being on the floodplains. During monsoon, most of the area is inundated. The main beels (wetlands) of the area are Phokolai, Dorou (both outside the Sanctuary), Sagunpora, Ghoka, Tokia and Jarjaria. The main channels that feed the area are Dimou, Boloma, Balijan and Singorajan. Pani-Dihing and adjacent areas are known for migratory waterfowl, while there are also important resident species. It used to be a hunters paradise, and people from Sibsagar town used to go for shooting ducks and geese. Now sport hunting has been stopped, but poisoning of waterfowl still goes on. The strip of swampy reed jungle of the northern border comprises chiefly Arundo donax and plants of the genus Alpinia, Vetiveria zizanioides and Saccharum spontaneum are also common, whereas Phragmites karka is becoming rarer, possibly because of collection by the villagers. Thorny vines wind around these tall grasses and during the summer rainfall, it becomes impenetrable with thick clumps of Eichornia crassipes.
