Abstract: The process of forest thinning creates more space for growth and nutrition of trees. After thinning, the increment of diameter and volume increases significantly. For evaluation of economic efficiency of commercial thinnings, the data for 1st and 2nd commercial thinnings was taken from Tauragė state forest enterprise, Žygaičiai district. 26 plots of 1st commercial thinning and 9 plots of 2nd commercial thinning were selected for the analysis. Data of Ponsse 'Beaver' harvester and Ponsse 'Gazelle' forwarder were used to calculate labour productivity and technological costs. Costs of forest harvesting and extraction of timber to the roadside using Ponsse machinery was 98,11 LTL/ m3 in 1st commercial thinning and 58,57 LTL/ m3 in 2nd commercial thinning. The profitability of the thinnings was 7,45 LTL/ m3 in 1st commercial thinning and 44,26 LTL/ m3 in 2nd commercial thinning
