Abstract The aim of the work was to determine which part of biomass remains in the forest in the form of so-called logging residue. In order to achieve the result, the analysis of wood volume harvested in the final felling was carried out, and the total volume was broken down into different parts of trees. Furthermore, to estimate the wood volume of the forest stand, on each of the experimental plots 10 model trees were chosen based on Draudt method. Assuming that the thickness of wood acquired from forest is bigger than 4 cm, it is possible to assume that the part of biomass which remains in the forest in the form of the branches and conifer needles ranges from 10% to 12% of general amount of biomass.
