ABSTRACT


The results of a study on damage of forest soil and trees during timber
harvesting works using the MHT-182HVT harvester are presented. Synthetic indexes
of forest tree and soil damages were determined. A synthetic damage index for
trees remaining in the forest after the harvesting operation reached the value
of 8.14%. A special attention was paid to deep wounds damaging the wood tissue.
However, trees with this type of injuries constituted only 2.26% of the total
number of trees remaining in the harvested area. A synthetic forest soil damage
index was 2.85%. Also the change of the soil compaction index in the harvester
working area was determined. The compaction was determined in two variants. In
the first variant the machine was moving along a skidding road covered with tree
debranching residuals (branches and tree tops), and in the second variant no
such a cover was present. In both cases the results were compared with soil compaction
measured in the control plot.

Key words: harvester, soil compaction, tree damage, timber harvesting technology.
