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.A18 - Niveau 5 : Chênaies-charmaies sud-alpines
Description
Fragmentary mesophile or meso-hygrophile formations of the Insubrian pre-Alps, the northern Apennines, the Ligurian Apennines, the Esterel and the Tanneron and very locally, the southern French Alps (forˆt du Saou, Dr“me), with Quercus petraea, Quercus robur, Fraxinus excelsior, Tilia platyphyllos, Tilia cordata and Carpinus betulus, developed on deep soils in conditions of sufficient atmospheric and edaphic humidity. They represent a transition between the medio-European formations of the Pulmonario-Carpinenion and Galio-Carpinenion on the one hand, the southeastern formations of the Carpinion illyricum, and perhaps the southwestern formations of the Polysticho-Corylenion, on the other hand.
