This association includes dry grasslands dominated by Festuca pallens, occurring on gentle slopes of small granitic or gneiss hillocks. In the past these grasslands were used for low-intensity grazing, leading to local soil erosion, which fostered long-term maintenance of this vegetation type. The range of this association is restricted to the warm, dry region along the upland fringes of the Bohemian Massif in southern Moravia.
