Tokai Hilly Land Spring-fed Mires. 03/07/12; Aichi; 23 ha; 35°05'02"N 137°12'59"E. Quasi National Park. A cluster of six small oligotrophic spring-fed mires at an elevation of 100-300m that occur in three main areas (Kamitaka, Onshinji, and Yanami) in adjacent catchments, but are hydrologically linked because of underground seepage from the Yahagi River system. The mires are representative examples of such wetland types that once used to be common in the biogeographic region but have since been lost due to development. The wetland supports many rare and endemic plant species that are adapted to the oligotrophic conditions of Tokai Hill, including a number that are locally called 'Tokai Hill Land Elements' because they have their main distribution only at the site. These include 'Shiratama-hoshikusa' Eriocaulon nudicuspe, 'Mikawa-shiogama' Pedicularis resupinata var. microphylla and 'Tokai-komousengoke' Drosera Tokaiensis. As a result of land development elsewhere, these are the only remaining spring-fed mires that are still in good condition. The clusters of wetlands are currently well conserved and protected under national law. They represent a water reservoir and support the agriculture carried out downstream. Ramsar Site no. 2060.
