U11
Volynian-Polesian hardwood alluvial forests (Quercus robur) in combination with alder carrs (Alnus glutinosa), willow scrub (Salix acutifolia) and tall reed vegetation (Phragmites australis)
Description
Three-layered, light pedunculate oak forests (canopyclosure 60-90 %, height of 60 to 160 year old trees 18-30 m) with Ulmus laevis, Tilia cordata, Populus tremula, Betula pendula, Alnus glutinosa, Sorbus aucuparia and Fraxinus excelsior. In the shrub layer (20-50 % degree of coverage) Corylus avellana, Cornus sanguinea, Frangula alnus, Prunus padus and Euonymus verrucosa. Convallaria majalis, Aegopodium podagraria, Asarum europaeum, Milium effusum, Scrophularia nodosa, Stellaria holostea, Geum urbanum, Lathyrus vernus are in the herb layer (20-40% coverage). Oak forests with black alder are the most frequent. Many hygrophilous species are represented in the herb layer. The incidence of (sub)boreal species is typical here.
