Carici humilis-Seslerietum caeruleae

Photo on

This is a drier type of Sesleria caerulea grasslands which includes a number of dry grassland specialists but only few dealpine species. At some sites it constitutes the natural vegetation of rock outcrops, but it is also found in secondary habitats, where it had extended under the influence of grazing. It usually occurs on limestone and rarely also on base-rich siliceous rocks such as basalt. It is most common in the Bohemian Karst and in the Vltava valley near Prague. Some sites are found in dry areas of northern Bohemia and in the Svratka valley near Tišnov.
