Abstract: | Several central European species have failed to reach the British Isles because of the early separation from the continent. The two tree species Fagus sylvatica and Carpinus betulus reached southern England but were unable to spread much further. Other species, such as Acer pseudoplatanus, were only relatively recently introduced. Recent distribution maps for Fagus and Acer show an almost uninterrupted distribution in the whole British Isles. The beech must be considered to be an important element of the present potential natural vegetation; it has been planted widely and regenerates freely. The woodlands of Brittany may provide a model to enable us to visualize the possible species composition and appearance of these potential Atlantic beech woods.Nomenclature of vascular taxa follows Ehrendorfer (1973). |
