This grassland is the driest type of the alliance Koelerio-Phleion, occurring in areas where low precipitation is combined with predominance of acidic bedrock, mainly at the edge of the Bohemian Massif in south-western and central Moravia. It is dominated by Festuca valesiaca and contains several dry-grassland and sand-grassland species adapted to low pH. Mosses and lichens are common. Soils are shallow, developed on gentle slopes over granite, gneiss or decalcified sand. It is a secondary grassland type, formerly used for grazing and now mostly abandoned. Vegetation change in these very dry habitats proceeds slowly.
