Specifics of harvesting technologies in Scots pine (Pinus sylvestris L.) forest stands managed using clearcut and shelterwood system
Vicherková, Nikola ; Štícha, Václav (advisor) ; Macků, Jan (referee)
This bachelor thesis concerned the findings about mining technologies using in forest stands of the Scots pine (Pinus sylvestris L.), which are forest managed using clear-cutting system and shelterwood system. To obtain the needs informations and datas were used informations from another issues from works next authores and simultaneously were used owns terens works, which were watching using mining technologies in Scots pine forest stands. There were watching differences the mining technologies between clear-cutting forest system and shelterwood forest system and simultaneously there influence to getting dendromasis and timing demanding. Terens works were in locations Židlov and Skelná Huť, which are under management of VLS ČR divize Mimoň.

Comparison of the Performance of Individual Wood Logging Methods
Pudlo, Pavel ; Macků, Jan (advisor) ; Štícha, Václav (referee)
The aim of the bachelor thesis was to perform literary research on the topic of the productivity of individual wood logging methods for forest cover and verify this productivity by comparison of the time dimensions either by using the harvester or working with the woodcutters. The main contribution of the thesis research results are own measurement. Measuring of the productivity of individual wood logging methods was carried out in the conditions given by the method cut to length by salvage cutting, that launched because of hit by bark beetle or strong wind. The measurement was carried out on five stands with harvester and on two stands with woodcutters. It was a measure of one harvester operator and four woodcutters. The measurement was done with the help of cameras that caught the working times of woodcutters and the harvester. The resulting times, due to the productivity and stem volume of the trees, recorded times by harvester were better and for that reason that method had proven to be more effective. In one of the monitored stands the effectiveness has not been demonstrated, because the operator has not logged in this forest cover enough m3 of the wood and the work was, therefore, loss making and time consuming. By the work of the woodcutters has the efficiency and shorter working times showed in two stands, where the measurement was carried out. Their productivity has been effective there, for example, with regard to the low number of trees and the larger crop density, the harvester technology would not be efficient.

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.

Potential logging in stands outside the forest within Czech Republic
Ondřich, Libor ; Štícha, Václav (advisor) ; Šálek, Lubomír (referee)
This thesis deals with the potential of timber from forest stands outside the territory of the Czech Republic and the assessment itself non-forest areas. The work is divided into two parts. The first part includes research on non-forest woody vegetation, especially in the Czech Republic, the methodology for mapping the authors of these non-forest areas, and the results to which occurred at the end of this work. The second part contains a separate case study with its own mapping in selected areas of the Central Region. In conclusion then mentioned the part dealing with logging from areas outside forests, including data from selected companies and at the end of thesis of the mining potential of these areas.

Analysis of the Damage to Forests in Logging with Selected Logging Methods
Duffek, Petr ; Macků, Jan (advisor) ; Štícha, Václav (referee)
The aim of the bachelor thesis was a summary of a literature review dealing with the impact of logging by chainsaw on the environment. The processing of this topic was preceded by the description of the construction and history of the chainsaw, the treatment with this tool, and the chainsaw maintenance and safe work with it. Further, using chainsaw in forestry was presented and the damage occuring in forest ecosystem components after logging were highlighted. In conclusion, the origin and the extent of damage on the environment were described and processes eliminating these losses as much as possible were designed.

Horse hauling analysis
Bendová, Gabriela ; Hájek, Miroslav (advisor) ; Štícha, Václav (referee)
The aim of this study was to analyze the work horse covering the technical and economic aspects in the Giant Mountain National Park zoning department 34 Black Mine and capture cost analyzes horse blanket, I know him from his experiences in the period from 2011 to 2012. Thus, from the very start, which means setting up for the coachman, stables, horse paddock, recording facility, registry horses and the establishment of a trade license.
Briefly described the driver duties in irrigate the horses, which is his duty throughout the year. Regardless of his health status and climatic conditions. These duties involve the surrounding work like collecting manure, building corrals and care for the wellbeing of animals.
Acquisition horse unit plays an important role for the driver must choose correctly and the horse be good companion, as they had to in this difficult craft absolutely believe, so in order to prevent possible undesirable situations. You will see two different types of horses, which can be used in mountainous areas with their price.
Another part is the economic analysis and describing the necessary tools to clean wood and horse harnesses. It calculated fixed costs for the two horses in one year.
According to the accounting records of the costing and earnings for the five years of business operation and only in the period of active business license.
Evaluation skidding horses took place on the ground in the territory of KRNAP, workplace Department 505, 509, 510, 519 and 525 in the spring of 8.4. to 5.15 2014. wood- clean Lukas Benda horse Karina and Ferda.

Self-production of firewood
John, Petr ; Štícha, Václav (advisor) ; Kabeš, Antonín (referee)
Bachelor thesis deals with self-production of firewood in the national Park České Švýcarsko and Forest Management Děčín, comparing the self production of both entities. The theoretical part defines individual species of wood occurring in NPČŠ and Forest Management Děčín, describes procedures for logging through self production of wood and enumerates the legislation on self-production. The second half of the thesis is the practical part. There is the description of Forest Management Děčín and national Park České Švýcarsko. There is compared the extraction of forest and non-forest areas according to several established parameters (volume, share of total mining regeneration,incidental and thinning) and evaluation of the findings.

Ecological aspects of the energy use of wood chips
Ručová, Karolína ; Štícha, Václav (advisor) ; Jankovský, Martin (referee)
Currently, the importance of renewable energy sources (RES) is much higher than before. Among the most important RES we rank biomass, which consists of more than half of produced energy from renewable sources. Using biomass increases the utilization of wood fuels and greater emphasis is placed on their processing requirements. The purpose of this study is to assess the ecological parameters that affect the use of wood chips for energy purposes, based on a comparison of existing norms and standards. The first part is focused on theoretical use of wood waste and subsequent utilization of therefrom made fuel. Subsequently there is evaluated the use of fuel for energy purposes in practice. The work also includes examining factors (calorific value, humidity, etc.) affecting the quality of biofuels in different seasons. The contribution of this work is to document the flow of wood waste, proving the benefits of recycling wood waste and recommendation for action in the future.
