Nakaikemi-shicchi. 03/07/12; Fukui; 87 ha; 35°39'40"N 136°05'20"E. Quasi-National Park. Within the Japanese Mixed Forest biogeographic region, this type of low moor wetland is rare and not widely distributed. The peat sediment at the central part of the site is approximately 40 meters deep, representing a valuable record of changes in climate and vegetation during the past one hundred thousand years. It is also considered a biodiversity hot spot with more than 2,000 species of animals and plants inhabiting the area. It was initially developed for rice cultivation during the Edo period (1603-1868) and has since been used as unprepared wet paddies without improvement. Currently, cultivation has been abandoned for the entire field except for the wet paddies for conservation of the wetland. The Japanese Yellow Bunting, Emberiza sulphurata, listed as vulnerable by IUCN, occurs in the wetland. The visitor centre is managed by Tsuruga city and used for environmental education and communication; boardwalks, paths, and information boards have been built for the 15,000 visitors that visit the area each year. Incursion of alien species such as Procambarus clarkia (Red swamp crawfish) and Solidago altissima (Canada goldenrod) is seen as a potential threat. Ramsar Site no. 2057.
