Dostálová A., Mazánková Š. & Tájek P.: Impassable Wetlands of International Importance

Two new Wetlands of International Importance (the so-called Ramsar Sites) have recently been designated in the Czech Republic: the Jizera River Headwaters and the Springs and Mires of the Slavkovský les Mts. In total, there currently are 14 Ramsar sites in the Czech Republic.

The Jizera River Haedwaters include raised bogs and transition mires situated within the floodplains of the Jizera River Valley, in the central part of the Jizera Mountains, following the Czech-Poland state border. Dominating vegetation of raised bogs are non-forest plant communities and spruce forests. Variable morphology of raised bogs results from frost and wind erosion. There are elongated wet gaps and ditches and dry elevated peaks, which are very similar to the features of the north Scandinavian mires. Species poor fens border the raised bogs. Mire vegetation displays subalpine tundra character hosting combination of arctic, subarctic, Arctic-alpine and circumboreal species. Due to the habitat structure and local climate, the site also serves as a postglacial refuge for unique vegetation and fauna, such as spiders, diving beetles or dragonflies. The locality includes one of the largest characteristic raised bogs complexes in the Czech Republic and also in temperate Europe. Because of the political borders, Czech raised bog complex is adjacent to a large similar one in Poland where a Ramsar Site is under preparation to complement the Czech site. The western part of the Springs and Mires of the Slavkovský les Mts. consists of raised bogs and forest peat-bogs, transition mires and wet meadows in central and in the highest part of the Slavkovský les Mts. harbouring well preserved vegetation of the Bog Pine (Pinus rotundata) bog forests and bog spruce forests. Eastern part of the site is typical by non-forest fens, transition mires and wet meadows with wild mineral springs (particularly ferrous mineral springs) displaying unique mineral composition. Wet flat depressions in the plateau of the Tepelská vrchovina Highlands and back-to-back central part of the Slavkovský les Mts. are remarkable due to well preserved (though for decades abandoned) vegetation with numerous and abundant nationally endangered vascular plant species typical for wetlands.
