The Cerastietum is a community of calcicolous vernal therophytes with a phenological optimum in late April and early May. It forms a part of vegetation complexes of dry grasslands on limestone and other calcareous bedrocks, where it is confined to disturbed patches and the vicinity of rock outcrops. It is found in areas with dry, warm climate in northern and central Bohemia and southern Moravia.
