Abstract:

summary crown profile equations can be used to characterize the crown closure, crown-area profile, crown volume and crown porosity of a stand to predict individual-tree height growth, basal area growth and the probability of mortality in stands-development models, which is important to decide about the stand management. the purpose of this study was to build equations to predict the crown parameters of scots pine in mountain forest. different models to estimate crown ratio, largest crown width, height of crown base and height above the ground to the largest crown width have been studied using nonlinear regression. results obtained in the validation models are adequate to estimate the crown size of scots pine
