چكيده فارسي :
This study investigates basal area increment of individual trees in mixed species continuous cover orests in the north of Iran. Empirical data from the species Fagus orientalis, Carpinus betulus, Parotia persica, Acer velutinum, Quercus castanifolia and Alnus subcordata have been collected and analyzed with regression analysis. One general function for basal area increment has been estimated. Basal area increment is a statistically significant nonlinear function of the tree basal area and the competition
