Application of modern research techniques using possibility for remote sensing enables assessing not only biometric indices but also spatial position of the tree. This makes it possible to simulate individual tree, as part of a forest stand, including interrelation between trees in a stand. These variables include area of plant alimentation. The study was done on fifteen sample plots laid out in 40-135 year-old Scots pine stands of Chernihiv and Sumy regions. Experimental plots were laid with the means of Field-Map system, which made it possible to get data on the following parameters: crown projection area, lower crown height, height of the first dead branch, crown length. Additionally we calculated alimentation area of trees, average distance between neighboring trees and the number of neighboring trees. As a result, we revealed a relation between spatial and biometric indices of individual trees, and averaged spatial variables as well as mensurational parameters of forest stands.
