Abstract

To study of tree SPECIES DIVERSITY in relation to ELEVATION and some of STAND STRUCTURE Characteristics, area about 450 ha of Hyanan forests located in north-east of Ilam city was selected.46 plots 2000m2 were established in site using transects by random- systematic method. Variables in each plot were included tree diameter (DBH), crown maximum and minimum diameter for all trees, number of trees and tree species, and data of ELEVATION. Values of five biodiversity indices were computed by PAST software and then analyzed. Totally 6 tree species were presented in the plots which the most presentation was belong to the Quercus persica. Results showed that ELEVATION have significantly affected on diversity, richness and evenness of tree species and the middle ELEVATION classes had the most species richness and diversity. Evenness has the ascending trend with ascend of ELEVATION, but decreased in 2300m from sea level. Canopy density had positive correlation with richness but negative correlation with evenness.
