This diploma thesis is dealing with analysis and statistical evaluation of regeneration methods introducing silver fir to forests in the area LS Lužná, forest district Bor. The aim of this thesis was to make the measurements of silver fir plants growing in the existing permanent research plots, to establish new research plots and perform general evaluation of alternative regeneration approaches.
The theoretical part deals with the issue of silver fir regeneration, its expansion and areal, ecological requirements, usability and physiological description of this species were also taken into consideration. This part of the thesis was also focused on description of the various alternative ways of reintroducing this species to the forest. It was made a description of the principles of forest tending, natural and artificial regeneration of silver fir stands with respect to its environmental requirements. The biotic and abiotic pests of silver fir and effective defence against these pests were also discussed. It was made the analyses of factors affecting positively and negatively the growth and development of silver fir. Silver fir was described as an ameliorative and stabilizing tree species.
In the practical part of this thesis an analysis of local conditions on the ground Bor, LS Lužná; specifically analysis of climate, soil, light and growth conditions was performed. They were recorded and compared to findings on the permanent research plots (established in 2014) and newly established research plots. The results were evaluated by different growth conditions on the research and permanent research plots. The differences in growth conditions in the different regeneration variants were evaluated statistically.
