Panorama

Watarase-yusuichi. 03/07/12; Ibaragi, Tochigi, Gunma, Saitama; 2,861 ha; 36°14'20"N 139°40'56"E. National Wildlife Protection Zone. A natural river flood plain where the Watarase, Uzuma and Omoi rivers meet and includes the Watarse reservoir, an artificial retarding basin surrounded by an embankment managed mainly for flood control. Located 60 km north of Tokyo, it is representative of a Phragmites australis-dominated low moor wetland in the Japanese Evergreen Forest biogeographic ecoregion. The extensive reedbed is one of the largest in the biogeographic region and supports a diversity of wetland flora and fauna. The site has an important flood control function by retarding the flood water from the rivers that flows into the site, and then slowly releasing the water into the Tone River that flows downstream. It is also used for fisheries, recreation, and environmental education. The wetland is at risk of drying up due to excess deposits of earth and sand and is being maintained through excavation since 2010. Ramsar Site no. 2061. Most recent RIS information: 2012.
