Jhanjimukh - Kokilamukh

Site description (2004 baseline):

Site location and context
This site includes the riverine tracts of the Brahmaputra River near its confluence with one of its tributaries, the Jhanji. In addition, there are some lakes and marshes such as Digholi, Misamari, Kawoimari and Laujan, which harbour avifauna. Situated 30 km northeast of Jorhat, the district headquarters, this wetland complex is an important site for waterbirds. The terrain is flat, being part of the floodplains of the Brahmaputra. During monsoon, the major part of this area is completely inundated.

Key biodiversity

AVIFAUNA: Although a full checklist is not available, information on many threatened species is available. This IBA is particularly noteworthy for the records of Baer’s Pochard Aythya baeri, which has been listed as Vulnerable. It has been recorded in four beels within this site, Misamari, Digholi, Kawoimari and Laujan (Choudhury 2000). A few thousand waterfowl, including ducks and geese, winter in the area. Seven more threatened species were recorded in the area.

OTHER KEY FAUNA: Gangetic Dolphin Plantanista gangetica inhabits the rivers and various turtles are also found.

Pressure/threats to key biodiversity
MAIN THREATS: Aquaculture / Fishing; Encroachment for agriculture; Poisoning of birds.

Reclamation of beels, heavy fishing and poaching of birds are the main issues. A ‘bird festival’ like the one organised in January 2003, could generate interest among local people.
