Nakaumi. 08/11/05; Shimane, Tottori; 8,043 ha; 35°28'N 133°14'E. NWPA. A brackish lagoon located at the estuary of the Hii River system, linked to the Sea of Japan by a narrow waterway in the northern shore. The site is home to 80 species of brackish and sea fishes and is one of the largest wintering and staging spots of more than 75,000 birds and 260 species. Nakaumi supports more than 1% of the East Asian population of Tundra Swan, Common Pochard, Tufted Duck and Scaup. The site has a high value for fishery resources with average annual catch more than 500 metric tons. A strong environmental movement against a reclamation project for converting the lands to farmlands with freshwater flow has subsequently led to Ramsar designation. Main conservation measures include Anatidae census, regular national survey of the environment, and a Sanctuary established for Yonago Waterbirds. Ramsar site no. 1551. Most recent RIS information: 2005.
