Forest modelling: the gamma shape mixture model and simulation of tree diameter distributions

Table 4 Fractions of the DBHs >70 cm, assessing the frequency of trees representing the older generation in the sample; in all the investigated plots, the older generation was composed of trees with DBHs above 70 cm
