The thesis exhibits results of European beech (Fagus sylvatica L.) growth analysis, performed in the Vrhe forest management unit. On these beech sites there is a mixture of Mediterranean climate, which is dry, and continental climate with more precipitation and lower temperatures. For this purpose, 33 trees of beech on 6 locations were analyzed. Locations were between 515 and 690 m above sea level. There were two site units: Castaneo-Fagetum sylvaticae (on flysch bedrock) with four plots and Seslerio autumnalis-Fagetum (on limestone bedrock) with 2 plots. We analyzed height growth, diameter growth, site index (SI100) and red heart appearance. Despite border area of growth, soil conditions have the biggest impact on site indexes. The most productive was location on the site unit Castaneo-Fagetum sylvaticae on flysch, with deep ground and on south exposition. The established values of site index SI100 were between 22 and 33 m. Site indexes on the analyzed locations on limestone bedrock (SI100: 26-29) are higher than site index at Starod (SI100: 22-26). Because of border area of growth for beech the share of trees with red heart is high.
