Alnus glutinosa-Alnus incana forest on riparian and mineral soils
Description (English)
Riparian and non-riparian forests dominated by alder (Alnus glutinosa, Alnus incana), and sometimes ash (Fraxinus angustifolia, Fraxinus excelsior), typically without many softwood willows in the canopy and occurring throughout Europe along streams and small to medium rivers. The field layer can be quite species-rich.
