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.
