From the analysis of the data presented in the diagram in figure 3, we can notice that the
intensity of interventions at the regeneration cuttings in the forest stand from u.a. 3A is
almost equal in P1, P2 and R, in P3 extracting almost half of the initial forest stand,
aspect proved by the presence of a very abundant fructification at the oak species in the
years 1999-2000 (Maxim I. C., 2003).
