Abstract

In this study the effects of the silvicultural methods was investigated on STRUCTURE and REGENERATION of the forest trees in LOGGED and NON-LOGGED stands according to the importance of forest trees. The forest had two regions with same areas which one of them was LOGGED through SHELTER WOOD SYSTEM and another was NON-LOGGED. LOGGED stand was assessed after 10 years from harvesting.60 plots (1000 m2) and micro-plots (100 m2) were systematic randomly established in the field. The comparison of the diameter of trees between these two stands showed the significant difference (P<0.05). With comparison of the vegetative parameters of four trees near to plot center it was demonstrated that there was significant difference between two stands concerning diameter at breast height (P<0.05), stem height (P<0.05), crown height (P<0.01), basal area at breast height (P<0.01) and volume (P<0.05). There wasn’t significant difference for total height, minimum and maximum diameter of crown and basal area of crown. Comparison of the REGENERATION in micro plots of two stands indicated the significant difference at probability level of 99 percent for REGENERATION density of stands. Moreover, there was significant difference at probability level of 95 percent between two stands for REGENERATION quality. Moreover, the comparison of the statistical of the two stands of species the using non-parametric U Mann-Whitney test, there was significant difference at probability level of 95 percent between two stands.
