Fagus forest on acid soils

Classification des habitats EUNIS 2022

Descriptif de l'habitat

Forest dominated by beech (Fagus sylvatica and Fagus orientalis) on oligotrophic, base-poor mineral soils. It occurs through the Atlantic and continental areas of Europe and, at higher altitudes, in the submediterranean zone. Associated broadleaved trees are few and always subordinate in cover, though oaks may be co-dominant. Evergreen conifers like fir (Abies alba) and, at the altitudinal limit, spruce (Picea abies) can figure as minority canopy components. The field layer is generally species-poor.
