British Fraxinus - Acer campestre - Mercurialis perennis forests

Description (English)

Forests and woodland of Fraxinus excelsior, with Quercus robur (in the southwest), or Quercus petraea, Acer pseudoplatanus, Ulmus glabra (in the northwest), with an understorey dominated by Corylus avellana, frequently accompanied by Crataegus monogyna, Crataegus laevigata, Acer campestre, Sambucus nigra, characteristic of often calcareous base-rich soils in relatively warm and dry lowlands of southern Britain, distributed mostly in southern and central England, eastern Wales, southern and eastern Scotland. The field layer comprises Mercurialis perennis, Hyacinthoides non-scripta, Circaea lutetiana, Geum urbanum, Arum maculatum, Viola riviniana, Viola reichenbachiana, Sanicula europaea, Lamium galeobdolon, Carex sylvatica; Primula vulgaris and Glechoma hederacea, Anemone nemorosa, Deschampsia cespitosa, Hedera helix, Geranium robertianum, Allium ursinum, Teucrium scorodonia characterize geographical and edaphic subtypes. In humid northern and western Britain, outside of the range of Fagus sylvatica and Carpinus betulus, the separation between this unit and the ravine forests of unit G1.A41, developed on unstable screes and colluvions, is poorly marked.
