Panorama

Oku-Nikko-shitsugen. 08/11/05; Tochigi; 260 ha; 36°47'N 139°26'E. National Park. The site is composed of Senjogahara, Odashirogahara and Yunoko at 1400m asl. in altitude surrounded by mountains. Senjogahara is one of the largest high moors in Honshu Island with more than 100 species of swamp plants like cotton grass and Japanese azalea. The vegetation of Odashigahara shows characteristics of moor and grassland succession; whereas Yunoko is a freshwater lake with hot springs in the same watershed, almost in pristine condition and an attractive tourist spot. The area is an important breeding site for summer birds, mostly Latham's Snipe Gallinago hardwickii and Stonechat Saxicola torquata. During winter, the site is visited by many migratory waterfowls including Mallard, Wigeon, Tufted Duck and Smew. Colour change of decidous trees in autumn, traditionally called 'Koyo', is cherished by the Japanese for its landscape beauty. Potential threats to Senjogahara are sediment inflow, reduction of inflow, constructions of facilities disconnecting inflow from upstream, inappropriate drainage and intake facilities, tourist influx, alien invasive species, and overgrazing. Conservation measures regularly conducted by local organixations are nature walks, control of alien species, control foraging by deer, and capacity building training for youth. Ramsar site no. 1553. Most recent RIS information: 2005.
