The obtained results confirmed that the examined beech forests exhibit similarity with multigenerational, complex forests of primeval character. An argument in favour of this includes in particular: high stand volume, good forest health condition and a positive relationship between the process of tree survival (volume increment and ingrowth) and the decrement process. The wide peak distance of culminations of two traits is characteristic too: the number of trees in the lowest diameter subclass and the volume in the diameter subclass several intervals higher.   ER -
