This bachelor thesis deals with the evaluation of spruce production in three structures. Monoculture, a stand mix of European beech and Norway spruce, and a structurally differentiated forest converted to a selection forest with Norway spruce, Silver fir and European beech are evaluated. When evaluating the distribution of thickness and volume, the structurally rich stand is closest to sustainable management. In terms of the comparison of thicknesses, the monoculture has the highest competence, due to the highest number of individuals in the main stand. For the crown projections, the highest level of competibility is in mixed stands, mainly due to space filling by beech. In terms of growth of the tree base area (BAI), the main stand of the forest is the most productive in the conversion to selection and reaches the highest values. In a selective forest, the measure of thickness competiveness is somewhat biased by the high frequency of individuals concentrated in a relatively small area. This fact increases the thickness-competition index even when the trees involved are understory.
