Přeměna porostů náhradních dřevin jeřábu ptačího na ekologicky výhodnější dřevinou skladbu

The aim of my diploma thesis was to evaluate growth of underplanted beech, silver fir and Norway spruce on salvage clearings covered by rowan. The second aim of the thesis was to develop the most suitable techniques for vegetation reconstruction. 19 plots were evaluated and the results of rowan underplantings were compared among each other. Results of plots with beech underplantings show that plots with low rowan stocking level (0 - 2) have the best growth dynamics. Between stocking 3 - 5 the results of beech growth dynamics are still acceptable, but from stocking 6 the growth dynamics of beech is not favourable anymore. Norway spruce growth dynamic is the best with low stocking of rowan (0 - 2). Higher rowan stocking causes serious reduction in growth dynamics. Divergence of rowan stocking does not cause losses of underplanted trees. Fir areas were measured and assessed but could not be statistically evaluated because of insufficient number of plots
