Struktura porostů pionýrských dřevin a jejich obnova v přírodní lesní oblasti 29 - Nízký Jeseník
Haltof, René
The submitted diploma thesis deals with the structure of pioneer tree stands and their subsequent regeneration in the natural forest area 29 - Nízký Jeseník, created by successions after allochthonous spruce, specifically located at LS Vítkov and LS Opava (LČR, s. p.). The aim was to describe the structure of medium old forest stands with a predominance of birch in the area of interest, in selected forest stands, and to register all tree species. For the upperstory (trees over 2 meters), which is mainly formed by birch, measure the diameter of the tree at breast height. Then find out their growth potential and select target trees. For target trees, determine the diameter increment and also the length and width of the crown. For trees below 2 meters (understory), measure their height and differentiate them according to the origin – natural or artificial regeneration and also evaluate the growth potential of trees from natural and successful artificial regeneration. In accordance with the objectives of the thesis, the specifics of tending usable in forestry practice were formulated.

Ekologicko-produkční hodnocení strukturální probírky v dubových a bukových porostech na ŠLP Křtiny
Soukup, Tomáš
Bachelor thesis deals with the issue of structural thinning in medium old beech and oak stands on the Training Forest Enterprise Masaryk Forest (TFE MF) Křtiny. In the framework of the project of the new economic concept of "Dauerwald - Permanently creative forest at TFE MF Křtiny". Educational intervention consists of searching and releasing a defined number of target trees (100 to 150 pieces per ha). At the Soběšice and Borky, three variants of intervention with different degrees of release of target trees were always established. The educational interventions were realised in 2015. Presented research was then focused on measurement of dendrometry characteristics of the target and other trees and evaluating their production and quality. Secondly, the natural regeneration and its development were monitored as well. There, mostly no statistically significant influence of type of intervention on evaluated parameters were find. The actual impact effect can be measured more reliably with a longer time span.

Potenciál hodnotové produkce habru obecného v porostech ve stadiu převodu na les trvale tvořivý na ŠLP Křtiny (l.ú. Soběšice)
Vincour, Matěj
The aim of this thesis is to find out the potential of the value production of the European Hornbeam (Carpinus betulus L.). Namely in the stage of the transferring into forest that is permanently producing, at ŠLP Křtiny. Two young stands of European Hornbeam (Carpinus betulus L.), created by the natural renewal after the clear felling were found at the area Soběšice. Further, one adult stand with regeneration under the stand, was found. By the stands created by the natural renewal, educational intervention was undertaken. Target trees, which were then released according to the option of intervention, were found. In total, 122 target subjects were marked. Before the beginning of the growing season, in January 2018 the measuring of the diameter of standing trees from the ground with a dendrometry and then the mining were made. Analysing of the quality of these trees was made according to Schädelin classification. The statistical analysis proved the static significant differences of the thickness increment according to individual options of the intervention. By the altitude increment and the percentage of the live treetop was not proved. For the more precise conclusion of the influence of the different kind of intervention, longer period of time would be necessary. By the adult stand, with the appearing of the renewal in the undergrowth, comprehensive forest inventory of rejuvenation was made and commenced the plot. The part of the errand was also the finding of future potential subjects of the European Hornbeam (Carpinus betulus L.) and its qualitative evaluation.

Zhodnocení potenciálu pěstování stávajících lesních porostů jako strukturně bohatých v oblasti obce Javorník (okr. Hodonín)
Kománek, Martin
The aim of this thesis is to analyze the forest stand management in the area of Javorník village (Hodonín district). Sample plots were established in suitable stands. Stands were evaluated and data were used as input for the Sibyla simulator. Two models of crop development were simulated in this simulator. The first model was the release of target trees with subsequent tree harvesting. The second model was the approach of the owner, ie thinning together with regeneration under shelterwood. Simulator output data were used to evaluate the suitability of selected interventions. Of the two models is better the model of target trees and target thicknesses. This is more appropriate in terms of permanent production, more environmentally friendly approaches to the forest ecosystem and higher forest production.
