In this article, we shall analyse the forest road network and damage to forest stands in the Karst region caused by intermediate cut-to-length thinning of the Scots pine. The established density of skid trails at the worksite is within the values commonly found when using such technology. However, cut-to-length-thinning implies a higher degree of visible soil damage than chainsaw cutting with wood extraction performed by tractors. On the one hand, there is less damage at the analysed worksite, including a smaller surface of damage. On the other hand, more damage concentrates on the stem than on average in Slovenia. We found the most marked soil damage occurred with primary skid trails. A certain reduction of soil damage on the secondary and cutting machinery trails at the worksite was achieved by placing cutting remnants under the wheels of machinery - however, this was not performed to satisfaction. To attain optimum reduction of tree and soil damage with mechanical cut-to-length thinning, it is crucial to choose the machinery according to task, to set up a detailed plan of primary and secondary trails, and for the machinist to provide high-quality work.
