Tisa River.04/12/04; Koaice; 735 ha; 48°23´N 022°07´E. In southeastern Slovakia, the site includes a 6 km section of the Tisa River and its floodplain contiguous with portions of the river in Hungary and Ukraine. The site includes floodplain forests and shrubs, an oxbow lake and grasslands. It is part of a larger wetland important for the recharge of aquifers in the Tisa River basin, natural control of flooding and self-purification processes, as well as for maintaining biological diversity. It supports species vulnerable at international level such as the Corn crake (Crex crex), Geoffroy's bat (Myotis emarginatus) and the Sterlet (Acipenser ruthenus). The upper part of the designated section has natural river bed, but the lower part was changed by human interferences in the 1880s. Within the site, human activities include regulated recreation and tourism, hunting, pasture and extensive agriculture. There is high eutrophication in the oxbow as a result of pollution from nearby intensive agricultural practices. The site was also used for fishing before February 2000 when several heavy metals pollution spills originating in Romanian mines caused damage in river ecology. Ramsar site no. 1411.Most recent RIS information: 2004.
Tisa River Ramsar Site is part of the "Upper Tisza Valley" Transboundary Ramsar Site declared in November 2003 in conjuction with Felsö-Tisza (Upper Tisza) Ramsar Site (No. 1410) in Hungary.
