Abstract

The aim of the study was to compare the QUANTITATIVE CHARACTERISTICS of two Forest ASSOCIATIONs (Fagetum and Fageto- Carpinetum) at Kheiroudkenar Forest (Nowshahr, Mazandaran province, Iran), based on data collected from 1980-2003. The applied sampling method was systematic random with constant grid of 200*200 m. The plots (1000 m2) were located over 250 ha (125 ha for each forest ASSOCIATION).The results showed that in the FAGETUM ASSOCIATION there was not significant differences between the QUANTITATIVE CHARACTERISTICS at different periods, whereas in FAGETO-CARPINETUM ASSOCIATION, the difference was significant. As a result, elimination of some trees species, particularly hornbeam, during trees marking in order to convert the current forest ASSOCIATION to pure FAGETUM, might reduce the QUANTITATIVE CHARACTERISTICS in future in comparison to 1980. In FAGETUM ASSOCIATION, high proportion of the tree's volume belonged to moderate and high stem diameter values, whereas in FAGETO-CARPINETUM ASSOCIATION, high proportion of the trees volume belonged to high stem diameter values. This indicates a moderate aged forest at FAGETUM and old aged forest at FAGETO-CARPINETUM (bell and skew shape volume curve), respectively.
