The study was aimed to assess the integral value that determines wood properties - wood density at a moisture content of 0% and 12%. The wood density was evaluated in a sample tree with the presence of compression wood (CW). The density was determined for different zones describing the position of the wood in the stem (CW, opposite zone, two side zones). The CW zone had a higher density than the remaining ones. On the basis of the acquired data, 3D models were created for individual zones; they describe the variability of wood density along the stem radius and stem height. The influence of the radius seemed to be a statistically highly significant factor. When the proportion of CW in the sample was 80%, the wood density was 1.5 times higher than in samples without CW.
