Summary: | Considering the morphological characteries of trees and the structure of stands, different development stages could be recognized in natural untouched forests. The development stages as well as the dynamic of the stands are basic references for application and development of nature based silvicultural interventions. The aim of this research was to study the structure, qualitative and quantitative chareateristics of the main development stages (initial, optimal and decay) in two different plant communities of oriental beech forests, in the Caspian region. For this purpose two communities of Rusco-Fagetum and Carpineto-Fagetum in the experimental forest of Tehran University (Kheyroudkenar-Noshahr) were selected. In each community three sample plots, each one ha, were established and tree spieces, diameter and height of all trees were assessed. Moreover, one transect (10*100) was selected in each sample plot and the structure (vertical and horizontal profile) of the stand was studied. Results showed that all three stages could be recognized in the pure beech community, while the optimal stage has not been occured yet in the mixed beech–hornbeam community. Distribution of stem number, basal area and volume in different diameter and height classes of all development stages are given in this paper. |
