This grassland is usually co-dominated by Bromus erectus and Carex flacca, with a remarkable participation of the halophyte Plantago maritima. It occurs in the warm, dry area of north-western Bohemia with less than 500 mm of annual precipitation. It is found on toe slopes covered by dry grasslands, in shallow depressions and near springs. Soils are heavy, clayey, developed over claystone, marl or colluvial sediments. They are wet in spring and early summer but dry out considerably in late summer. In the past this vegetation type has been extensively grazed by sheep and goats.
