The spatial final cut optimisation
Kašpar, Jan ; Marušák, Róbert (advisor) ; Lstibůrek, Milan (referee)
For more than 150 years, timber indicators have been used for forest harvest scheduling in the region of current Czech Republic. With social changes and increased importance of forest yields and functions, there has been significant changes in forest management during this time. The changes in ownership structure after 1989 are most problematic from a sustainability standpoint. Also, the timber indicators cannot consider forest age structure, which is not ideal because even small changes related to abiotic and biotic disturbances may inhibit forest planning efforts. These changes to forest ownership and structure combined with current timber indicators make it difficult to ensure sustainable harvest levels over long time horizons. Methods of operations research, such as mathematical programming and heuristic methods, provide alternatives to historical harvest scheduling methods because they can account for forest age structure and spatial relationships over long scheduling horizons.

Growing Douglas-Fir in the area SLP CZU in Kostelec nad Cernymi lesy
Kubeček, Jiří ; Podrázský, Vilém (advisor) ; Marušák, Róbert (referee)
Douglas-fir (Pseudotsuga menziesii /Mirb./ Franco) is currently considered one of the most important introduced tree species in Europe; for example in Germany it is considered domesticated. By its production it surpasses significantly our domestic softwood and its importance is found both in amelioration and improving functions as well as in its ability to compensate for spruce, so far our most common species however retreating somewhere.
The work addresses the growth processes of individuals and stands of Douglas- fir and its selected environmental effects in regions of Kostelec nad Černými lesy, and Písek. The aim is to demonstrate the production potential, economic evaluation, describe the growth dynamics and the impact on soil quality in the stands. The methods applied will include dendrometric measurement, description of growth dynamics, profitability, sampling and analysis of humus and mineral soil horizons. Basic pedochemical characteristics will be analyzed: soil reaction, soil sorption complex, nutrient content in total and exchangeable forms. The results indicated a high produce ability of Douglas fir comparable to the one of Grand fir and exceeding the one of Norway spruce. In terms of stabilization and effects on soil also has better properties than spruce. In terms of amelioration resemble the qualities of deciduous trees.
The work follows on previous experimental investigation..The output provides quantification of the production and soilforming potential, yield assessment and recommendations for application in conditions of the University Forest Enterprise and the Czech Republic.

Evaluation of forest management plans based on operational inventory
Bílý, Martin ; Marušák, Róbert (advisor) ; Jaroslav, Jaroslav (referee)
The aim of the thesis was to evaluate the preparation of forest management plans for richly structured forests, especially the forest in national parks. The model area was National park Podyjí (Thaya Valley), whose territory has been operational statistical inventory repeatedly performed. The theoretical part of the thesis analyzes problems of legislative embodiment of the method and the issue of forest management in national parks with special care facilities. The main contents of the study were then evaluate the data from forest management plans in 2003 and 2014. In the final part examined possibilities for the use of operational inventory in terms of forest management and in terms of the objectives ofnature conservation in national parks and have designed some possible modifications to the methodology.
