DAMAGE TO TREES AND REGENERATION LAYER RESULTING FROM TIMBER HARVESTING WITH THE USE OF EQUIPMENT AGGREGATED WITH FARM TRACTORS IN THINNED PINE STANDS

Keywords: thinning processor, cable winch, farm tractor, early and late thinning, damage to trees and regeneration layer
Abstract:

The research was conducted in pine stands where selective early and late thinning was carried out with the use of NIAB 5-15 and HYPRO 450 debranching and cutting processors along with a FRANSGÅRD V-6000 GS cable winch aggregated with farm tractors. In case of cut-to-length system, timber harvesting was executed by means of processors and in case of tree-length system – by means of a cable winch. The harvested timber was forwarded to the depots in the second stage with the use of self-loading trailers or skidded with the use of a cable winch. Tree damage in case of processor technology oscillated at the level of 3.1-11.3%, and in case of a cable winch: 3.0-10.9%. The level of damage to the regeneration layer amounted to 4.1-27.1% for the areas where processors had been used. For the areas where timber was harvested by means of a cable winch, the level of tree damage was 5.2 -14.0% of trees growing under the main stand’s crown layer.
