Abstract :
Background: The fagus orientalis lipesky species includes around one-third of width and correspondingly, the standing volume in the mixed and partly pure stands of northern forests of Iran.. Present research has been carried out to investigate the effects of topographic factors on quantitative characteristics of oriental beech species in Nav Asalem forestry plan.Methods: According to purpose of the research, breast height diameter and height of the oriental beech trees were measured in three altitude levels (800 to 1650 m), five slope classes (0 to 50) and four main geographical classes and recorded on the corresponding forms.Results: The results of one-way variance analysis test showed that two factors of slope and the sea-level altitude had significant effects on quantitative characteristics of oriental beech species wherein Dunkan’s test was used to compare the means and eventually, the results showed that the lowest and highest rates of quantitative characteristics existed respectively in heights of 1300-1440m and 1440-1650m. Also, studying the slope, the highest diameter, cross-section and height of the beech trees were obtained in a slope of 40-50 percents.Conclusion: Thus, due to the nature and ecological characteristics of oriental beech and since the best habitats for the trees of this species to have the greatest diameter and height are the upstream and sloping regions, the results of this research show that Nav Asalem forest habitat is one of the best habitats of the target species.
