When compared with the other associations of the alliance Koelerio-Phleion, this grassland type occurs in slightly cooler areas. It contains less thermophilous species and is mainly composed of generalists adapted to dry and acidic soils. Mosses and lichens are common. This association is typical of gentle slopes with shallow, acidic soils over basalt, gneiss, granite or shale. It forms secondary vegetation at sites potentially supporting acidophilous oak or beech forests. These grasslands are utilized for grazing, but after abandonment they decline due to spread of tall grasses, shrubs and trees. The localities of this association are scattered in moderately dry areas of the Bohemian Massif.
