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.
