Ouchigata Lagoon is a stopover for a large number of Bewick’s swans, geese, ducks, etc. from Siberia between mid-October and late March. It is classified as one of Japan’s 500 most important wetlands. The lagoon and nearby rice fields are rich in aquatic plants such as common reeds and Manchurian wild rice, as well as gleanings, which serve as food for Bewick’s swans and other birds. Efforts are being made to increase the supply of microorganisms for birds to eat by flooding the rice fields during the winter. In Hakui City, people would like to observe Bewick’s swans and other wild birds in the natural environment. For that purpose, the members of Hakucho-no-sato Promotion Council and its supporters carry out environment conservation activities such as putting up signs to control the passage of vehicles and to increase awareness of the need for environmental protection.
