Atlantic and medio-European forests dominated by Quercus robur or Q. petraea, on eutrophic or mesotrophic soils, with usually ample and species-rich herb and bush layers. Carpinus betulus is generally present. They occur under climates too dry or on soils too wet or too dry for beech or as a result of forestry practices favoring oaks.

Description
Often low, open formations dominated by Quercus robur or Q. petraea, developed on superficial to deep soils associated with calcareous substrates in southern Germany, eastern and southern Belgium, eastern and central France; they generally constitute substitution forests of the Cephalanthero-Fagion, either regressive phases brought about by coppicing or recolonisation phases permitted by abandonment of Bromion grasslands.
