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.
