Riverine Fraxinus - Alnus forest, wet at high but not at low water

Description (English)

Riparian forests of Fraxinus excelsior and Alnus glutinosa, sometimes Alnus incana, of middle European and northern Iberian lowland or hill watercourses, on soils periodically inundated by the annual rise of the river level, but otherwise well-drained and aerated during low-water; they differ from riparian alder woods within units T151 and T162 by the strong representation in the dominated layers of forest species not able to grow in permanently waterlogged soils.
