The aim of this thesis was determination of basic density of silver birch (Betula pendula Roth.), from segments taken from the breast height, in relation with the stand structure. The research was conducted in area Nízký Jeseník and Slavkov. The segments were taken by Pressler auger in three stands with different age per the area. The average basic density of the silver birch is 491,1 kg∙m-3 (Velká Polom) and 504,2 kg∙m-3 (Slavkov). The positive correlation was found out between the basic density and the age. The dependency between basic density with height and diameter at breast height is very low. The other matter was the determination of variability of basic density along the stem height– the values increases with the height of the tree. The analysis of possible relation between the basic density and the average tree-rings width showed that the dependency is low.
