In the Caspian region of northern Iran, research was carried out in semi-virgin (natural, unmanaged) mixed forests of oriental beech (Fagus orientalis Lipsky) covering an area of 43 hectares. Twenty-two gaps produced from natural falling of trees within the area were recognized, and the area of the openings together with the regeneration process was studied. Results showed that the area of the openings varied between 163 m2 and 1683 m2, caused by falling of 1 to 6 trees. Natural regeneration depended on the gap size, and was established within the openings with different compositions. The regeneration process occurs in the so-called initial and decay development stages of virgin forests, which supports the uneven-ageness, heterogeneity and vertical irregularity of the stands. No regeneration gap was observed in the optimal stage with regular structure.
