Abstrakt: In suburban forestry there is a need not only to manage a maximum financial result, but also to support recreational and aesthetic forest functions. Thus, these forests need professional treatments in the form of proper silvicultural methods to maintain stand stability. One of these methods is cultivation of mixed stands with Norway spruce. This study examines the mortality of spruce growing in stands in lower forest vegetation zones with time series of 50 years and the changes in biomass production in young variously mixed stands in three different vegetation zones. According to the results, it is beneficial to grow spruce in the range from 5 to 10% of admixture in stand establishment stage. Due to silvicultural treatments and inter species interactions, spruce representation in a stand may increase to 30% in the mature stands. Spruce trees tended this way in young age partly will be outcompeted by other species, but the remaining individuals will adapt to the existing environmental conditions and thus the whole stand will be more stable. Biomass production of spruce trees depends on its representation in the stand. The higher the spruce admixture, the lower will be average spruce tree biomass. The study indicated that in young stands up to 30% of spruce representation, its biomass was up to 100% greater than in spruce monocultures.
