Abstract

The Process of NATURAL REGENERATION including establishment, of seedlings under dead, and mother trees are, among the most important phenomena in silvics. The aim of this article is to quantify the impact of dead, and mother trees on the density of established seedlings in closed and open parts of a BEECH - HORNBEAM forest. According to the field observations, parcel no. 9 with closed canopy and no.11 with open canopy, both in Jamaleddinkola district of CASPIAN FORESTs, were chosen for sampling. DEAD TREEs were taken as the center of sampling plots. Also in a 30-40 m distance from DEAD TREEs, 2 or 3 mother trees-same species, D.B.H and height- were seleted as the center of sampling plots. At each of these centers, seedlings were counted in-a circular sample plot (R=10 m). The results show that the seedling density of BEECH is higher than that of HORNBEAM and other species but there is no significant difference observed between HORNBEAM and other species. This result is the same under DEAD TREEs as well as mother trees. The seedling density of BEECH and HORNBEAM established under DEAD TREEs, closed stand, is higher than that under mother trees. Other species have the same density under dead, and mother trees of closed stand. Seedling density of BEECH established under DEAD TREEs in open stand is higher than that under mother trees of open stand but regarding HORNBEAM and other species there is no significant difference observed in seedling density.
