This work contains working processes using during separately methods, way of measurement of distorying and reporting results. In the next part of this work are presented results of distroying measurement of odd bush, which are caused by different mining and transport technologies in the area of University forest company in Zvolen. We explored harvest technology, tractor technology with using universal wheel tractor and technology, which i sused for pulling uf of wood by animal power. We made testing places in bushes, where we wrote amount of mined trees, amount of odd trees and destroyed trees. We found out character of destroying during destroying assesment, range of hurts, bang location to tree trunk and distance of destroying trees from link. We found out the biggest destroying intensity druring tractor technology, which achieved 41,6%. We found out the least destroying during animal power technology with destryoing intensity 37.3%. Harvest technology from destroying intensity view was in the middle of destroying 39,3% of trees. At the end of this work are valuation results of our measurement with cooperation of results from others authors and proposals related to decreasing of bush destroying intensity.
