This vegetation type is dominated by the narrow-leaved tussock-forming grasses such as Festuca valesiaca and Stipa capillata. It contains many generalist species of central and eastern European dry grasslands, but several species of continental steppe are also present, e.g. species of the genus Astragalus. It occurs on south-facing slopes in warm, dry areas of northern and central Bohemia and in southern Moravia, mostly on deep soils over loess and on soft calcareous sediments, occasionally also on limestone or basalt. These grasslands have been traditionally subject to grazing, however, today most of them are abandoned.
