Abstract: The aim of the study was to propose and verify a model which, based on multi-criteria evaluation of selected input data, determines the category in terms of the environmentally friendly use of individual skidding technologies for each stand. A farm tractor, skidder, cable system, forwarders, and forwarders in combination with harvesters were selected as model skidding technologies. The selected input parameters included: slope inclination, ground bearing capacity, risk of logging-transportation erosion development, presence and size of obstacles, skidding distance, terrain shape and age of stands. Weights of input parameters for multi-criteria evaluation were defined by means of Saaty's matrix and geometric mean of rows. Stocking and areal representation of spruce and fir were added to the evaluation of forwarder-harvester combination. Different equipment (standard tires, low-pressure tires, wheel tracks) and climatic conditions (dry, wet) were also taken into account in the evaluation of the model. The model was applied to the selected experimental territory in the upper part of the basin of the Oskava River.
