Nakdong estuary provides the largest wintering grounds for migrating waterfowls in Korea, and was designated Natural Monument No. 179 in 1966. Nakdong barrage and related construction-projects finished in 1987 to increase freshwater-supply to nearby Pusan metropolitan area and to reclaim the vast intertidal areas for land development. Changes on distribution, primary productivity, and standing crop of Schoenopluctus triqueter, the dominant species in this intertidal flats, were investigated after the construciton, during the 1988-1990, and were compared to those before the construction. Total standing crop. tuber biomass and net primary productivity of S. triqueter increased in 1988 and 1989, but decreased slightly in 1990. Increase of tuber biomass means an increase in available food, thus the carrying capacity, for swans wintering in this area. Habitat environment of this estuary should be protected and managed as a wintering ground for migrating waterfowls, inspite of the construction of the barrage.
