The vegetation structure of the beech and oak forests in the northeast part of Lower Saxony of NW Germany, and the oak forests on Mt. Sobaek and also the beech forests in Ulreungdo, Korea, were compared. Generally the canopy of the German forests is much taller than the Korean forests. Differentiating from the Korean forests, Fagus species and Quercus species usually occurred together in the German forests. On the physiognomy and stratification, two types were observed in the German forests. The oak forest of type 1 had a tree layer of 9∼29 m in height, with a sparce cover in the shrub layer. The beech forests of type 2 had a tree layer of 17∼35 m, with a lower cover in the shrub layer than the oak forest. In Korea the beech forests attained 10∼18 m in height and had much more abundant shrub layer than the German beech forests. The Korean oak forsets had a height of 6∼24 m with the most abundant shrub cover. In general the canopy of beech forests in Korea and Germany are taller in height on average than that of the oak forests in each country. On the life form structure, all the forests studied here were rich in hemicryptophytes. Chamaephytes showed a higher percentage in the German beech and oak forests located in higher latitudes than in the Korean beech and oak forests. Therophytes were present in the German beech and oak forests and the Korean oak forests, but the beech forests in Ulreundo did not have not that life form. Compared to the German beech and oak forests, the Korean beech and oak forests had more plentiful taxa floristically. The beech forests and the oak forests in Germany were unified to the class Querco-Fagetea and the class Quercetea robori-petraeae, respectively. Likely it seems to be that the beech forests and the oak forests in Korea belong to the class Fagetea crenatae and the class Quercetea mongolicae, respectively, if we support the two classes system. It is presumed that these two classes in northeastern continent. Asia are counterparts of the two classes, the Querco-Fagetea and the Quercetea robori-petraeae of Europe from a viewpoint of vegetation structure.
