The diploma thesis is focused on the problem of analysis of the logging, shipping timber andthings related with demage of the soil and udergrowth. The technologies of logging and processing of wood are beeing highly significant in the forestry, resulting in technical provides of mechanization. Of course, a big role in the selection are these different criteria: limiting factor of its terrain slope, strain of the soil, performance of the machine and in finally stage finances for correct investment.And therefore the main thing is to look for the right combinations and the right solutions for continuous improvement of this segment of forestry and to reduce demaging of undergrowth and soil and of course to increase the effectivity of mechanization.
