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.A15 - Niveau 5 : Chênaies - Charmaies faméniennes
Description
Sub-Atlantic forests of Quercus robur and Quercus petraea, mostly low-canopied, with Carpinus betulus, Sorbus torminalis, Betula pendula, Populus tremula in the subcanopy or the understorey, developed on soils with an alternating hydric regime, mostly clays derived from the alteration of Devonian schists, characterized by the abundance of Carex flacca and the coexistence of acidocline and calcicline species, typical of the sub-Hercynian Fagne-Famenne depression where they constitute a highly distinctive, almost continuous, forest-belt.
