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.A16 - Niveau 5 : Chênaies-charmaies subcontinentales
Description
Quercus robur or Quercus petraea forests of eutrophic or mesotrophic soils of subcontinental and continental northern and central Central Europe and of Eastern Europe. Carpinus betulus is generally present in their western representatives, widespread in Central Europe and western Eastern Europe. They are richer in lime, Tilia cordata, than the sub-Atlantic forests of units G1.A13, G1.A14 and 41.25. They are of more northern character in their area of mutual approach than the Balkanic forests of unit G1.A1C. Their southern limit of occurrence follows the Carpathian arc, the northern rim of the Podolian plateaux, and, farther east, the southern limit of nemoral forests.
