Irish-British pedunculate oak-alder-ash forests (Fraxinus excelsior, Alnus glutinosa, Quercus robur) with Salix atrocinerea
Description
Light, multi-layer pedunculate oak-alder-ash forests (70-80 % degree of coverage) with a tree layer (up to 18 m) of Quercus robur, Fraxinus excelsior, Alnus glutinosa and Betula pubescens. Alnus glutinosa seems to occur more frequently on wetter soils. A second tree and shrub layer consists of the same species as well as Corylus avellana, Salix atrocinerea, Sorbus aucuparia, Crataegus monogyna and Ilex aquifolium. The shrub layer is more or less closed. The herb layer is species-rich and is characterised by hygrophilous species. Rubus fruticosus sometimes forms a dominant layer of approx. 1 m in height. The introduced species Acer pseudoplatanus and Fagus sylvatica also migrate locally. Occurrences of (sub)atlantic species are typical.
