A broad, shallow bay of the Caspian Sea and associated delta wetlands at the mouth of the Sefid Rud River. With a variety of marine, coastal and freshwater and brackish inland wetland types, the Site is important as a spawning and nursery ground for fish, and as a breeding, staging and wintering area for waterfowl including Dalmatian Pelican (Pelecanus crispus). The Site regularly supports at least 1% of the population of three species in the region: teal (Anas crecca), wigeon (Anas penelope) and gadwall (Anas strepera). The Site is used for recreational and commercial fishing including aquaculture, livestock grazing, reed cutting, hunting, rice farming and recreation and tourism. Bujagh National Park is an Important Bird Area and is considered a potential site for the reintroduction of the Siberian crane. The original Ramsar Site (designated in 1975) was significantly enlarged from the original area of around 500 hectares to the current area of over 3,400 ha.
