This alpine heathland includes low-growing, species-poor stands dominated by Calluna vulgaris, accompanied by Vaccinium myrtillus and V. vitis-idaea, graminoids and lichens. It is the natural vegetation of wind-swept ridges in the highest summit areas at altitudes above 1400 m in the Krkonoše Mountains, and less frequently also in the Hrubý Jeseník Mountains.
