Abstract

In this study, the effect of forest management was investigated in managed and unmanaged NATURAL FOREST stands at district 7- Shenrood (Siahkal). Parcel 2 of the given district (81 ha) was selected as an unmanaged region while parcels 3 and 4 (80 ha in total) were considered as managed ones. The survey was done based on a systematic method. However, the starting sampling point was selected based on a randomized method. The dimensions of the survyed area were 200 m × 100 m with circular plots each of 0.1 ha. At each sampling plot, we investigated the kinds of species, their diameter at breast height (DBH) of more than 12.5 cm, the height of two control trees and the quality condition of trees. We also recorded all tree regenerations with DBH of less than 12.5 cm. The results showed that there are no significant differences between the trees in average of the cross-sections, volume per hectare and the degree of tree quality in managed and unmanaged parcels. There were also no significant differences between numbers and standing volume per hectare, Lorry’s mean height and mean regeneration in the managed and unmanaged forest stands were at 0.05 confidence level. The composition of beech species was found 83.87% and 97.15% in unmanaged and managed parcels respectively. It seems that management practices in forest stands caused an important change from the mixed beech forest stands to the pure, and it also increased reestablishment of plants mostly beech trees. The results also revealed that the altitudes range is suitable for establishment of beech species.
