Table II
Stand characteristics of the mixed stand constructed from yield tables after Jansen et al. (1996). The first two lines indicate the individual contribution of each species to the Douglas-fir/beech mixture which is displayed in the third line and was initialised in 4C for the Speulderbos (NL) and Freienwalde (GER).
