This association includes mesic acidophilous oak forests dominated by Quercus petraea agg., less frequently Q. robur, with frequent admixture of Betula pendula, Pinus sylvestris or Sorbus aucuparia. The shrub layer is usually sparse. The herb layer is species-poor and usually dominated by the graminoids Avenella flexuosa or Luzula luzuloides. A moss layer is often well developed. This association occurs on nutrient-poor acidic soils on both flatland and slopes. Especially on flatland and gentle slopes it often evolved under long-term forest management that involved nutrient depletion. In the Czech Republic it occurs mainly in areas with poorly-weathering acidic rocks of the Bohemian Massif, especially in central Bohemia and south-western Moravia, but also in other areas.
