Porovnání přesnosti hybridní GPS + GLONASS a běžné GPS aparatury v podmínkách lesních porostů
Klváček, Ladislav
The work presents a comparison of the accuracy and reliability of collecting geospatial data by hybrid and conventional GPS apparatus in terms of selected forest locations at the SLP ML Krtiny. For this comparison, the chosen standard equipment was the Trimble GPS Pathfinder ProXH which processes signals only from the global satellite navigation system NAVSTAR GPS and the hybrid receiver Pathfinder ProXRT receiver, which is able to receive GPS signals and the signals of the global navigation satellite system GLONASS. For this purpose, a self-testing kit was designed consisting of a Trimble Tornado dual-frequency antenna, which was the connected to the GNSS receivers via a signal splitter unit. The advantage of this system is that both GNSS devices receive signals from a common antenna, ensuring that observational conditions are completely identical. Data collection was carried out at three sites with different terrain and forest conditions and on the spot with the best observational conditions (roof LDF). Observations were made for a period of one hour at each location. The processed results revealed that the GLONASS system used in conjunction with the GPS system delivered less accurate results than expected. In only one instance did the hybrid system deliver accurate data; this was when observational conditions were particularly poor, due to forest conditions and terrain. In this case the GLONASS plus GPS system benefited from a continuous satellite signal, whereas the GPS system suffered from only intermittent satellite contact. After the application of post-processing correction through the virtual reference station network CZPOS the margin of error was generally reduced, resulting in a lower RMS for both receivers, but the higher number of satellite contacts with the hybrid system resulted in more accurate results only under especially poor environmental conditions.

Návrh výukových materiálů pro průřezové téma Člověk a životní prostředí pro střední odborné školy přírodovědného zaměření
Neradilová, Ivana
The Bachelor's thesis presents a proposal of the educational project n technical subjects for an education in Ecology and environment, as well as in other related disciplines within a mutual theme "The man and environment". A part of the thesis submits educational documents as a sample of worksheets. The teoretical part of the thesis specifies a terminology regarding to an environmental education and a public education (further as EE), describes the EE's importance and shows EE's current state and its development at high schools. It also provides a list of associations, which occupy themselves with EE's theme. There is a description of educational methods, which focus on the educational project. The theme is systematically divided into two mutually relating and independently functional project days (for students in the third year). It also provides a timetable and additional informative remarks for pedagogues, which enable to facilitate their work within the proposed project. The proposed educational project is called "The forest -- more than trees" and concerns with trees's function and forest ecosystems not only from an ecological point of view, but the attention is also given to the social aspect.

Mapování a návrh úpravy pramenných vývěrů v polesí Valšovice
Čechová, Martina
This thesis presents the mapping and drafts of the modification of water springs in the school forest district of Valšovice which belongs to the the Secondary Forestry School in Hranice. The goal of the thesis was to make laboratory analyzes, annual monitoring of natural springs, measurement of the spring intensity, temperature, pH and oxygen content. The values have been evaluated and shown in tables and graphs. The thesis contains proposals of modifications of all the natural springs there. The proposal of the chosen spring is complemented by a graphical representation and a hand sketch presenting the location of the modify natural spring, information panel and a bench in the area where the spring is located. Furthermore the thesis looks into the proposal of the widening of the existing nature trails of Valšovice where the springs are located and the proposal of information panels of the natural trail.

Ekonomické dopady zavedení certifikátů FSC a PEFC do společnosti hospodařící v lesním hospodářství
Neshybová, Zuzana
The subject of this work is to determine the economic impact in the implementation of the certification systems PEFC and FSC. I have chosen the forest company, for which there were ascertained potential costs and revenues for introduction of these certifications and their maintenance in any company. For my research were used Porter's five forces analysis, questionnaire and theoretical measuring of costs. Recommendation based on collected data, was given to chosen company.

Application of forestal pedagogy in the didactic programme "Treetop trail"
ŘÍDELOVÁ, Vlasta
The Bachalor thesis introduces a didactic programme which provides elementary school teachers to fulfil aims of selected educational fields of the General educational programme through field schooling and develop pupils´ key competencies of elementary education. Lower elementary school pupils are the target group of the programme.. Forestal pedagogy represents an instrument to fulfil the aims of the programme. The thesis provides information about the environment which the programme is set in, deals with the job of a forestal educator, forestal pedagogy in the Czech Republic, its methods and aims. The work describes relations between the General educational programme, forestal pedagogy and the didactic programme. Primarily, the thesis describes a structure of the didactic programme and all its elements in detail, and specifies methodology of all participating subjects of the programme in a clear way.

Sustainable management of forest ecosystems - indicators of biodiversity
HOŠKOVÁ, Jana
This bachelor thesis is devoted to the topic of biodiversity and indicators for sustainable production of forest ecosystems. The work is conceived as a literature review of the problems and tries to view the various topics, with the problems that are closely related. Attention is focused on the individual chapters in particular summary (search) basic knowledge related not only to the nature and persistence of forest ecosystem functions of forests in terms of their environmental stability and durability, especially the work was focused on the identification of the main methods for monitoring biodiversity in forest ecosystems. The main objective of this work is to compare conventional and natural regeneration of forest ecosystems, and on this issue was also seen in terms of soil organisms (invertebrates), which can be considered as indicators of changes in biodiversity in forest ecosystems.

Ecological consequences of habitat loss in landscape matrix and the effect on populations and communities of model species
HELLEBRANTOVÁ, Adéla
The effect of fragmentation on populations was studied using epigeic beetle collected by pitfall traps with ethylenglykol. Pitfall traps were placed at three sites and namely in: artifical spruce forest, bio-corridor and meadow in the vicinity of České Budějovice on agricultural landscape. The material was collected from May to September. Beetles were determined and classified into goups according to the level of tolerance to anthropogenic influence. The communities (species richness and its activity) were compared in cited biotopes (fragments) in the agricutlural landscape. The highest number of species and its activity was detected in the bio-corridor. The lowest number of species and its activity was found in the spruce forrest. Thel effect of size of biotope was not found. At a meadow and biocorridor previled beetle species named as eurytopic which are characteristic for deforested habitats strongly influenced by human activities. In the forest, the other half consisted of RII. Group, which are adaptable inhabiting habitat moderately affected by human activity.
