G1.A1 - Niveau 4 : Boisements sur sols eutrophes et mésotrophes à Quercus, Fraxinus et Carpinus betulus
Description
Atlantic, medio-European and eastern European forests dominated by Quercus robur or Quercus petraea, on eutrophic or mesotrophic soils, with usually ample and species-rich herb and shrub 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 favouring oaks.

G1.A17 - Niveau 5 : Chênaies-charmaies calciphiles subatlantiques
Description
Often low, open, xerophile forests dominated by Quercus robur or Quercus petraea, developed on superficial to deep soils associated with calcareous substrates in Hercynian southern central Germany, eastern and southern Belgium, eastern and central France; located within the range of the Pulmonario-Carpinenion, they offer similarities to the Galio-Carpinenion and generally constitute substitution forests of the Cephalanthero-Fagion, either regressive phases brought about by coppicing or recolonisation phases permitted by abandonment of Bromion grasslands.
