This thermophilous vernal community is dominated by the endangered annual grass Sclerochloa dura. It occurs on trampled, dry and sunny sites on dirt roads in rural landscapes, e.g. among vineyards, arable fields and in less urbanized parts of the villages. The community occurs scarcely in the warm and dry regions in northern Bohemia and southern Moravia.
