Abstract:

Presented in the article are the results of the research related to the selection of the most suitable technology of forestry utilization in high beech stands upon final cutting. Research was conducted in the mountainous region of Serbia. Two methods of cutting and processing were analyzed especially from the aspect of the extent of damaging that occurs on the regeneration following the skidding of the massive wood mass thicker than 3 cm without bark. Extent of the damages is expressed by the number of damaged plants. Implementation of the semi­tree length method implies processing of trunk segments of optimal length from the aspect of damaging extent and maximal financial effect. By the implementation of the semi­tree length method major damages on the regeneration do not occur in relation to the damages that occurred by the implementation of the assortment method, or in other words, the advantage of semi­tree length method is that beside the technical roundwood and cordwood, a part of the branchwood, fork sections etc. is also extracted. This quantity accounts for 11% of the massive wood volume and presents potential raw material for energetic utilization. Extent of the damages depends on the dimensions of processed assortments or the length and the diameter as well as the angle that the axis of the processed assortment forms with the trail. Damages that occur when the semi­tree length method is implemented in the phase of skidding are significantly smaller in relation to the damages that occurred by the implementation of the assortment method in equal working conditions and besides that, the costs of skidding are also lower. By the proper selection of felling direction and formation of the optimal load in conditions of optimal accessibility, the semi­tree length method presents an effective technological solution for wood harvesting. Complexity of the operations increases with the increase of the height of the regeneration, so it is of special significance that the final cut is conducted on time.
