In the Balkans, it shows some hybridisation with oriental beech; these hybrid trees are named "Fagus" × "taurica". In the southern part of its range around the Mediterranean, it grows only in mountain forests, at altitude. Although often regarded as native in southern England, recent evidence suggests that "F. sylvatica" did not arrive in England until about 4000 BC, or 2,000 years "after" the English Channel formed after the ice ages; it could have been an early introduction by Stone age humans, who used the nuts for food.
