This is a forest type dominated by Fagus sylvatica, in places mixed with Carpinus betulus, Quercus petraea agg. and other species. Its herb layer is dominated by Carex pilosa and contains other species of eastern or southern distribution, in addition to mesic forest species shared with other types of beech forests. In the Czech Republic this association is confined to the Carpathians and the eastern edge of the Bohemian Massif, where it occurs, on average, at lower altitudes and warmer sites of the colline to montane belt than other beech forest types. Soils are cambisols developed on flysch sediments and other parent material.
