The paper presents results of discriminant analysis for Kraft's classes of trees. Kraft's classification is based on the tree position in the stand social structure and its crown development and extent. Belonging to a given social class reflects a position of a tree in a stand, and through this, its growth potential. The aim of the analysis was the choosing variables which mostly determined the Kraft class of tree and the construction of discriminant functions which well classify data to Kraft's classes.
