The problem of assessment of damage to trees to be left for growth on logging operations in the performance of selective logging. The process of interaction with crowns fell a tree. It is shown that the application of fuzzy set theory to solve this class of problems is more correct approach. Made substantial formulation and formalization of the problem of possible damage to trees when pushed down on the basis of the theory of fuzzy sets. For the mathematical description of the input and output parameters suggest appropriate fuzzy membership function. On the basis of fuzzy inference with defuzzification method Mamdani, possible damage function is obtained as a function of crossing crowns in horizontal and vertical planes. The practical implementation of fuzzy inference can be run in FIS Editor application MatLab Fuzzy Logic Toolbox. Possible damage resulting function can be used for fuzzy modeling of logging operations to the assessment of possible damage during felling.
