The new look at the forest economy takes into considerationmaximum protection of forest ecosystems, first of all. The purpose of the research was to estimate the influence of wood harvesting and skidding technologies on forest environment, particularly on soil and remained stand. The traditional wood harvesting and skidding technology (compact sawing machine, tractor with winch) was more friendly for soil environment than the newest technology (harwarder). Decrease of the negative influence of engineering wood harvesting and skidding process on forest environment is possible through application of both technologies and technical means correctly selected for the purpose. Besides, the operator’s practice is of a significant meaning.

The present work makes an attempt to recognize the kind of logrolling means used while logging on the basis of range of disturbances of the top soil layer. The investigation covered horse skidding and skidding made with the MultiFKS hoisting winch. Graphical analysis of the diagrams representing disturbances characteristics of the top soil layer (surface and volume) allows one to perform correct recognition of the causative factor responsible for 18% of the damages. Application of artificial neuron networks allowed us to correct typing-out logging environment for 75-96.8% disturbances of the top soil layer.
