Impact of habitat diversity and wood debris accumulation on macroinvertebrates
Nováková, Barbora ; Matoušková, Milada (advisor) ; Rödlová, Sylva (referee)
The revitalization of watercourses should be amended to restore the natural landscape water regime. Healthly waterflow should contain a morphologically rich bed with added dead wood and alternating pools and riffle. All these structures are colonized by varied fauna, that is distributed according to its dietary requirements. These problems are devoted to the research part of work. Another part is focused on the research of three tributaries in the upper basin of Blanice river near Prachatice. The location is thanks to the population of the freshwater pearl mussel (Margaritifera margaritifera), significant not only in Czech but also in european scale. Therefore, there is an important aspect of environmental protection. Given the importance of the site, there are experimental research carried out by Department of Physical Geography and Geoecology at the Faculty of Charles University in Prague. The practical part is based on the determination of macroinvertebrates revitalized Sviňovického brook and the subsequent evaluation of water quality. Samples of macroinvertebrate were collected using method PERLA and subsequently identified in families. For use BMWP score and ASPT index, the quality of water placed in the appropriate category of water quality.
Stroje a strojní linky pro zpracovní dřevního odpadu - štěpkovače
Vaněk, Martin
Thesis describes machines and mechanical lines for the processing of wood waste - chippers. The teoretical part reports about chippers and their ulitization. Thesis introduces basic division of chippers with presentation of basic types of crushing devices. Czech and foreign producers are presented with their produced types of machines. At the end of the teoretical part are described individually machines and machinal lines with complete work process. This process is used for felling and following disposal of wood mass in wood lands and in cities. In the practical part thesis compares desinged machine sets in field laboratory mensuration. Measured values were compared. Costs and economical aspects of the compared machine lines are quantified in the end.

This thesis deals with the utilization of the heavy horses in the forest distrikt Dolní Bečva, which is part of the forest management area Rožnov pod Radhoštěm. The work deals with the skidding of timber by heavy horses in the woods compared to other technologies. The work is evaluated by nature, production and economic conditions related to the skidding of wood horses. It also show a detailed overview of the work done by horses for the years 2011, 2012, 2013, when the horses were in 2011 skidded 8332,23 m3 total of 2541,13 cubic meters from stump to roadside and 5791,1 m3 from roadside to skid road, in 2012 were horses skidded 7197,21 m3 total of 2202,78 cubic meters from stump to roadside and 4994,43 m3 from roadside to skid road and in 2013 were horses skidded 4589,92 m3 total of 1621,55 cubic meters from stump to roadside and 2968,37 m3 from roadside to skid road.
