This thesis deals with the measurement and evaluation of soil damage after the passage of forest technology in the area of flysch zone of eastern Slovakia. Measurements were made on experimental plots in three stands with similar natural conditions on the territory of the Military Forests of the Slovak Republic, OZ Kamenica nad Cirochou. Timber logging was made by the skidder and forwarder, which was used to collection the harvesting residues. The last stage of the restoration of the stand was carried in all stands. Track depths were measured from which the average cross section for each stand was formed. Measurements performed showed damage levels 5 (severe damage) in two stands and grade 4 (moderate damage) in one stand. Then, soil samples were taken which were further examined in the laboratory. The results of the measurements showed increased moisture and bulk density after passing through the forestry mechanization and after compaction of the soil, compared to the intact soil directly in the stand. Further statistical investigation has shown some dependence between bulk density and soil moisture. Results in stand 63 B10 are r = -0,33, track r = -0,92, and in the middle r = -0,95. In stand 64 C00 r = -0,58, in track r = -0,85 and in the middle r = -0,64. In last stand 16 D10 r = -0,59, track r = -0,91 in the middle r = -0,94. Dependence between soil density and slope has not been proven. Results in stand 63 B10 are r = -0,03, in the track r = -0,54 in the middle r = -0,43. In stand 64 C00 r = 0,38, track r = 0,14 middle r = 0,03. In stand 16 D10 r = 0,30 track r = 0,28 middle r = 0.
