Damage reduction of trunks of trees left for growing during selective felling

Abstract

Forest management improvement is an important task, especially in the context of the development of forest areas with a depleted resource base. When carrying out non-clear cuttings, the main operation that has the greatest negative impact on the trees left for growing is skidding, during which trees located along the portage and, especially, at the turn, can receive damage, consisting in damage to the root system and trunk bark. It is possible to prevent damage to the trunks of trees left for growing by using fencing devices, which can be made from logging resi-dues located in the cutting area, or from slabs obtained by sawing logs. The use of a protective device does not require large expenses due to the use of substandard wood; after skidding the devices can be easily removed and put on other trees.
