Abstract: 

The use of wheeled skidders is well accepted practice for the extraction of timber from the forest, but this has tended to cause the greatest environmental problems. The aim of the study was to evaluate if slope gradient, number of machine passes, soil depth, and soil moisture of skid trails influence soil compaction on a fine-grained soil, and to quantify these effects. The study was designed as a factorial experiment and the effects of 0, 10, -10 and -20% slope, 5, 15 and 25 cm depth, 20-30, 30-40 and 40-50 % soil moisture and different levels of compaction were applied by varying the number of skidding cycles: 1, 5, 8, 10, 15, 20, 25, 30 passes. A Timberjack cable skidder was used and the study location was the Kheyrud Forest. An increased number of machine passages increased soil bulk density, but most of the compaction occurred after the initial few passes. Uphill skidding increases compaction more than downhill skidding. Increases in bulk density were still important at the maximum sampling depth of 30 cm. Soil bulk densities at 5, 15, and 25 cm depths on average 35, 22, and 17% are higher than densities in undisturbed soils.
