This association includes heathlands dominated by Calluna vulgaris and accompanied by Vaccinium myrtillus and V. vitis-idaea. They occur on acidic, nutrient-poor soils in submontane and montane belts. Most stands are secondary at deforested sites, but some stands of this vegetation may occur naturally on rock outcrops. They are distributed in most mountain ranges of the Czech Republic, and occasionally also at low altitudes, where they mostly occur on cooler north-facing slopes.
