Abstract

Evaluation of Forest structure can be regarded as one of the most usable working tools in modern forest management. In this study, the structures of trees species in Fagus, Fagus-Carpinus and Fagus-Acer types were investigated and compared in Hyrcanian forests. In order to do this research, five plots one-ha inventoried in each forest types Nave Asalem-Gilan that were homogeneous environmental conditions, and calculate the Mean directional, Uniform angle, Mingling, DBH dominance and Height dominance and Distance to nearest neighbours indices. The result of mean directional and uniform angle indices showed a random positioning for the trees in the studied types. The result of mingling index showed a low mixture for three studied types. The result of this index indicated an intra-specific competition for Fagus orientalis and an inter-specific competition for other species. The average value of DBH and Height dominance indices showed a relative similarity among the studied types. The result of these indices showed that some species such as Acer velutinum and Alnus subcordata are dominant and species including Cerasus avium and Ulmus glabra are dominated. The result of distance to nearest neighbors index showed relatively greater density of trees in Fagus type compared to other types examined. The comparing of similar species structure in different types showed a non-significant difference for positioning, DBH and height dominance and tree density features. This comparison showed a significant difference in mingling feature of Fagus orientalis, Carpinus betulus and Alnus subcordata in reviewed types. The utilized indices in this study are very useful tool to analyze of forest types' structures and also the ecological features of Tree species.
