Fig. 4 - Dynamic of the trees number distribution on diameter categories when
applying the regeneration cuttings in u.a. 4 A
From the analysis of the data presented in the diagram in figure 5, we can notice that the
intensity of interventions at the regeneration cuttings is relatively equal in the three
interventions, the forest stand being grown in a period of about 4 – 5 years, due to the
fact that it occurred two very abundant fructifications at the oak species in the years
1993-1994, and respectively 1999-2000, because of the favourable stational conditions
(Florescu I.I., Nicolescu N. V., 1996).
