Stipetum tirsae

This dry grassland is dominated by Stipa tirsa and contains species of both the meadow steppe and dry steppe. Within the Festucion valesiacae, it occupies the least dry sites on gentle slopes or footslopes, usually covered by deep calcareous soils. It is a relict of the vegetation of the Pleistocene steppe on plains in dry lowlands – a great rarity today since it has been converted into arable land in most areas of original distribution. It is most common in the south-western part of the České středohoří hills, in the middle Ohře valley of northern Bohemia and at a few sites in southern Moravia.
