Trees: attitudes and visual preferences
Stachová, Jana ; Čermák, Daniel
The study presented in this paper uses a representative sample of the Czech population to analyse the relationships between attitudes to trees and preferences for landscapes with trees. We ask whether a positive assessment of the environmental functions of trees in general and old and dead trees in particular, leads to preferences for wilderness-like forms of the tree landscape. The results show that people who appreciate the environmental benefits of trees are more likely to prefer transparent and organised landscapes with trees, whereas the more specific environmental attitude appreciating old or dead trees is reflected in higher preferences for wilderness-like.

Perception of the role of green in different sizes of municipalities
SLIPKOVÁ, Šárka
This diploma thesis called "Perception of the role of green in different sizes of municipalities" focuses on different kinds and types of green in towns, villages and in the open countryside. In the introductory part the thesis defines the term green and describes its basic functions and characteristics, which improve the environment and have positive effect on human´s health. In the next chapters the thesis describes the role of green in urban areas of different sizes and reflects how people perceive green vegetation and how green affects their feelings when they are in different areas. The aim of the thesis is to map and make an inventory of types and the amount of green in villages Hůrky and Lišov. In addition to mapping, other data was collected via questionnaires and all data was subsequently analysed. The closing part evaluates outcomes of the research.

Dendrological evaluation of interesting trees in selected parts of České Budějovice town
HRUBEŠOVÁ, Kristýna
In the urban area of České Budějovice, there was carried out a dendrological survey of selected localities during the year 2018 and 2019. There were observed especially the area of the park Na Sadech, Háječek, Sokolský ostrov, park on the Malše river embankment, Staroměstský park and park Na Dlouhé louce. The survey was focused on interesting, notable and in pedagogical practice usable woody plants and their selected dendrometric parameters. Altogether 67 woody plants were evaluated. The most often evaluated taxon was Common Oak (Quercus robur) with 9 representatives. In the inventory there were registered 23 introduced taxons coming largely from North America. All woody plants were drawn in map plans, which are included in results of this work. To make the received data and information usable and available in practical teaching at primary and secondary schools, there was also an online map created in the application Google Earth as part of this work, which includes complete photo documentation of rated woody plants. Results of this work can be used as teaching materials especially for educational walks joined with trees identification.

Don't we see trees for the forest?
Stachová, Jana ; Petřík, Petr
Trees and forests are essential for the stability of the planet. But how do people think about them in a broader context? Are the old, dry and solitary ones also important? How does Czech society perceive them? Not only these questions were answered by experts from many disciplines. In addition to well-known challenges, forests face new challenges that require an innovative approach and interdisciplinary cooperation.

Vizualization and Generation of Realistic Tree Models
Pafčo, Tomáš ; Herout, Adam (referee) ; Pečiva, Jan (advisor)
This thesis deals with generation of realistic tree models and theirs real-time visualization. Proposed generating method offers versatile spectrum of variable parameters, so it is able to create particular species of broad-leaved or coniferous trees with relative high amount of authenticity. It is also possible to manage level of details and complexity of tree geometry, which influence the rendering time and amount of frames per second. An OpenSceneGraph, the open-source toolkit, was used to visualization. A demonstrational application was created in C++ to visualize several types of trees on WinXP platform.

The influence of trees on contamination of soil with 137Cs
TRNKOVÁ, Michaela
Nuclear weapons testing in the atmosphere and accidents in nuclear energy facilities in the last 50 years caused significant contamination of the environment. Half-life of certain leaked radionuclides is several decades and therefore they are still present in today's environment. That is the reason why there is still on going monitoring of radiation situation in the Czech Republic in order to determine the behaviour and kinetics of anthropogenic radionuclides in the environment and the severity of radiological impact on humans. The results of this monitoring serve to review the radiation situation, observe long-term trends and last but not least to gain new knowledge that could facilitate the management od radiological emergencies. The aim of this thesis was to measure the content of 137Cs in soils under and around leafy tree crowns in the area affected by radiation fall and to find out whether the tree's crown has an effect on the distribution of 137Cs in the soils below them. To this end, a research question has been set: Do tree crowns affect the distribution of cesium in the soils below them? For better intelligibility, the introduction of the thesis is devoted to information about ionizing radiation, basic terms and quantities in the field of ionizing radiation, sources of radionuclide contamination, especially the Chernobyl nuclear power plant accident, environmental and population contamination, and elements important for the practical part of this work. The theoretical part is followed by research methodology. The soil samples were collected under five leafy trees of the Walnut species that met the set criteria for collection. Under each tree, samples were taken in three directions at an angle of 120° always at the trunk, in the middle of the crown, at the edge of the crown and outside the crown. Thus, 12 samples per tree, a total of 60 samples. Dry and purified soil samples were measured by semiconductor gamma spectrometry which determined 137Cs radionuclide mass activity values as well as naturally occurring radionuclide40K. Graphs were generated from the measured values. Despite the frequent deviations that may be caused by natural phenomena or human activities, it was found out that tree crowns affect the distribution of 137Cs in the soils below them.

Succinct encodings of trees
Juraszek, Adam ; Mareš, Martin (advisor) ; Majerech, Vladan (referee)
We focus on space-efficient, namely succinct, representations of static ordinal unlabeled trees. These structures have space complexity which is optimal up to a lower-order term, yet they support a reasonable set of operations in constant time. This topic has been studied in the last 27 years by numerous authors who came with several distinct solutions to this problem. It is not only of an academic interest, the succinct tree data structures has been used in several data-intensive applications, such as XML processing and representation of suffix trees. In this thesis, we describe the current state of knowledge in this area, compare the many different approaches, and propose several either new or alternative algorithms for operations in the representations alongside.

Natur Garden in Kindergarden
Rubešová, Ivana ; Jančaříková, Kateřina (advisor) ; Skýbová, Jana (referee)
I devoted in the diploma thesis a theme natural gardens in kindergarten, which is starting gaining popularity in Czech republic from abroad's model. I define in theoretical section how the garden should look like and also significance of environmental effects on child's personality development. And I approximate history of open-air teaching. I describe into the details process creating garden in natural style and her elements focusing on plants, especially trees and shrumbs. The work includes also practical experience from process of creating natural gardens in selected kindergarten. I mention at the end of theoretical section options for funding garden. I based research section on questionnaire method and I evaluated data qualitatively. I had adressed kindergarten teachers throughout Czech republic by online questionnaire. 302 respondents answered. The object of research section was to find facts relate climbing children the trees between kindergarten teachers throughout Czech republic. I analyzed the obtained data and after I evaluated them. I found that children are usually not allow to climb the trees on garden in kindergarten (75,1% respondents). The main reason is the fear of children's security, inappropriate trees for climbing or trees absence. Surprising finding is, that out of...
