This community is dominated by the clonal herb Geranium sanguineum, accompanied by other broad-leaved thermophilous herbs. It is found in warm, dry areas such as northern and central Bohemia and southern Moravia, usually on steep, south-facing slopes. The soils supporting this vegetation type are mostly shallow, developed over limestone, marlstone and basalt, occasionally also over base-poor siliceous bedrock. At many sites the Geranium sanguineum stands occur in partial shade. At some sites it is the natural vegetation on the forest-steppe ecotone, but occurrences along the anthropogenic forest-steppe interface seem to be more common.
