In this thesis, we analyze the increment of beech (Fagus sylvatica L.) depending on site conditions. All measurements were carried out in autumn 2014 in the area of Leskova Valley. In the context of the tasks we set up 12 plots dominated by beech. Plots were established on three different types of relief: sinkholes, slopes and ridge. For each tree its height, breast diameter (1.3 m from the ground) and a geoposition on the surface was measured. In addition, for all analyzed trees at breast height the increment core for the last 10 years was taken. Nine dominant beech tree were drilled to the pith. The results showed that we have the highest growing stock in sinkholes. Average radial and relative basal area increment are declining with age of trees. Radial increment culminates sooner as the relative basal area increment. We have found that trees between 200 and 300 years of age have on average constant increments, which hardly decline. The suppressed trees have lower radial increments, but the highest relative basal area increments. The slopes have maximum radial and relative basal area increments. By increasing the distance between the trees an average radial increment of trees increases, while the basal area increment does not.
