Zpracování strategického scénáře vývoje zásob a těžeb buku na ŠLP "Masarykův les" Křtiny s výhledem na 30 let
Mašek, Michal
This piece of work seeks to suggest an optimal strategy for beech felling to avoid high felling fluctuations in the future. This particular suggestion is based on the last two forest management plans. Divisions based on the age class in the last two decades were analysed (described?) and compared with each other. The calculations of felling plan were based on two different scenarios. Based on felling balance comparison, both scenarios could be used. The second scenario is preferred based on economic reasons.

Comparison of J-105 poplar (Populus nigra X Populus maximowiczii) coppice plantations with different rotation period
Tvrský, Filip ; Štícha, Václav (advisor) ; Javůrek, Petr (referee)
The topic of the thesis are fast growing trees, specifically the Japanese J-105 poplar
(Populus nigra x Populus maximowiczii). The work is divided into theoretical and practical part, which is the theoretical part of the description of the Japanese poplar, a description of the selected locations, problem description biomass in general, and is introducing legislation that topic to the available sources.
The outcome of the thesis are the results of the evaluation of revenue and growth in the Japanese J-105 poplar cultivation short rotation way in the three-year, four-year and seven-year rotation period.

Vyhodnocení plantáže RRD založené na zemědělské půdě v majetku Lesů města Brna, a.s.
Stuchlý, Ondřej
The work deals with the analysis of production and economic parameters of plantation short rotation coppice LMB in LS Deblín. Production plantation was assessed after 7 and 8 years since its inception through a network of inventory plots and stencil poplar. Surveys to be wood volume (m3) and the total biomass (o.d.t). Plantation economy was measured as the difference between revenues and costs. The survey was also regenerative experiment to assess the influence of the width of the cuts on the growth of poplar saplings. Total volume production of tree plantations for 2012 was set at 46,95 +/-9,7 m3. Total volume production of tree plantations for 2013 was set at 63,41 m3 +/-10,5 m3. Total dry weight biomass for 2012 amounted to 23,31 t/ha ie 3,33 t/ha/year. The following year, the total biomass dry weight was for 8,42 t/ha greater. The average production was also greater, it reached 3,97 o.d.t/ha/year. The total cost of the plantation in the first rotation reached 79 022 CZK. The cost of timber harvesting in 2012 amounted to 7 485 CZK. The total yield of the plantation in 2012 was 72 906 CZK. The profit in 2012 amounted to -6 116 CZK . Total revenue for 2013 amounted to 99 249 CZK. The profit in 2013 amounted to 20 227 CZK. Next experiment shows vigorous sprouting capacity. Wider cuts (3 lines) is generally larger than the cuts closer (2 lines). It was also found that the wider lines is greater proportion of sprouts in the greatest height class (+2 m).

Growing of over - growth tree species
KOSTOHRYZOVÁ, Lenka
The comparison of agronomical practices and land capability of selected deciduous with coniferous wood species, especially fast growing tree species on agricultural land, is the theme of this bachelor work. This work deals with the cultivation of fast growing tree species, the comparison of their growth figures and agricultural techniques. Fast growing tree species were cultivated in these localities: Svatý Jan nad Malší (Chlum nad Malší), Všemyslice- Neznašov and Lesy města Český Krumlov s.r.o. The research was focused on the comparison of yields of deciduous (poplar) with coniferous trees (spruce, larch), agricultural techniques. There is the comparison of yields with yields from the available literature, in conclusion.
