Southeastern Moesian subalpine beech forests

Neutrophile or acidophile, often open, forests of generally low [Fagus sylvatica] or [Fagus moesiaca], with [Acer pseudoplatanus], [Acer platanoides] and [Acer heldreichii], sometimes with a small admixture of [Abies alba] or [Picea abies], invaded by Adenostyletalia species, developed at the tree limit in the subalpine or upper montane level of the Rhodopids.
