Zhodnocení využití těžebně dopravních technologií u Arcibiskupských lesů a statků Olomouc s.r.o., polesí Chvalčov
Putala, Martin
This thesis is focused on recommendation of the use of effective and acceptable measures in context with current solution of growing salvage harvesting of timber. The thesis is separated into two parts. The first part leads to the selection of optimal logging technologies in accordance with chosen criteria. The selection criteria are edaphic category, slope inclination, terrain type, age of the area and the representation of woody plants. The priority of the set criteria is the selection of spaces intended for the use of harvester technologies due to the high portion of salvage harvesting of timber. Other commonly used logging technologies are proposed in areas which exclude the use of harvester technologies. In connection to excessive timber harvesting, the second part is focused on the removal of timber from the area of interest with the characterization of the use of paired transport on forest roads. An analysis of timber removal form LHC Chvalčov has been made alongside with a proposal containing minimal parameters for timber storage in connection to the use of paired transport and a map of LHC Chvalčov with marked places indicating timber storages suitable for paired transport.

Zhodnocení příčin nahodilých těžeb na LHC Svitavy v období 2009-2017
Tyller, Martin
The aim of this study was to determine causes and consequence of salvage cutting on the subjected territory in 2009-2017. Next aim was to evaluace these cutting in depending on abiotic factors. It was recommended to work with data of evidence of salvage cutting from the owner. On the base of evaluation the salvage cutting and causes was carry out the interpretation of these information. The next aim was to propose measures for stabilization the salvage cutting on the interest territor based on detected information.

Technologie zpracování dříví v kalamitních těžbách
Vašíček, Bedřich
BEDŘICH VAŠÍČEK: Technology of processing of calamity loggings The objective of this bachelor work is assessment of the calamity on the 22nd of June 2011 in the forestry management in Pec pod Sněžkou. It concerns damages caused to forest cover in the forest section Zelený potok as a result of meteorological phenomenon called downburst. To process the calamity there were used several technologies and the objective of the work is to evaluate their application in difficult mountain locations of National Park Krkonoše. Further aim is to highlight the influence of the forest calamity on bucking, converting the wood into cash and purchasing of services necessary for the wood processing. Further area solved in this work is the Occupational Safety and Health, because generally logging belongs among one of the most risky works.

Posouzení zdravotního stavu vybraných smrkových porostů na revíru Lipina, Lesní správa Prostějov
Pospíšilová, Lucie
In the second half of the last century, a decline of secondary spruce stands emerged to an increased extent. This fact is connected with incorrect species composition of woody plants, low resistance, gradual temperature increase and rainfall decrease, increased occurrence of insects and fungal pathogens. This theses aims to objectify causes of spruce decline in the Forestry District in Prostějov, the forest Lipina, the forest stands Zadní hory, to evaluate the impact of abiotic and biotic stress factors, to outline passibilities of damage reduction and prolongation of spruce existence in unsuitable localities provided that spruce cover is transformed into mixed cover.
