What aerial photographs can reveal about the state of habitats in Šumava National Park?
Hamarčák, Mário ; Křenová, Zdeňka (advisor) ; Kindlmann, Pavel (referee)
The utilization of remote sensing in the field of nature conservation and landscape management has recently increased tremendously. Possibility of implementing data obtained by remote sensing in GIS has created an increasingly powerful tool also for appropriate management of protected areas. This bachelor thesis delivers a brief overview of remote sensing methods, projects that use these applications and the possibility of their application in practice. Also examples of research activities in the field of remote sensing aimed primarily at protecting and monitoring the state of forests are presented. Finally, a draft methodology for the analysis of changes in habitat qualities in the area of interest, the Šumava National Park, is proposed. Keywords: Habitats, Management of protected areas, Habitats for Natura 2000, GIS, Aerial photographs, Remote sensing

Monitoring výskytu invazních neofytů v povodí Zdobnice (CHKO Orlické hory)
Vágner, Jan
Mapping of selected invasive neophytes along the rivercourse of Zdobnice river, particularly in the part of the river flowing through the protected landscape area of the Orlické mountains, was done within this bachelor thesis. The monitoring took place in July of 2016. A 1:10 000 map was used for recording of the occurrence of above mentioned neophytes into their respective extension categories. 20 fytocenologic images from respective biotops were created during fieldwork. Forest type Groups were then assigned to their respective images. Turboveg 2.0, Microsoft Excel 2016, and ArcGIS 10.3.1 were used for the elaboration of the results, where a map in digital form was created. The most abundant type was Glandular nettle, which occurres mostly in ruderal biotops. Other types, such as Reynoutria japonica or Telekia speciosa participate in the invasions greatly as well. The rest of the taxons from Reynoutria genus were not observed in the incriminated area. The biotop of gravel river bedding was evaluated as the most threatened by the cooperation of Reynoutria, Telekia a Impatiens. When compared to similarly focused works, we can say that Impatiens confirmed its dominant role even in this work, as well.

Návrh mokřadního biotopu v katastrálnímú území Zbýšov
Gernešová, Lucie
The diploma thesis deals with the design of the wetland biotope in the cadastral area of Zbýšov (Vyškov district). The main aim of the proposal is to create a naturally close wetland biotope, which would allow for the occurrence of wetland plants and animals by its conditions and at the same time it would contribute to the increase of biodiversity in the given area and at the same time it would become a functional component in terms of water retention in the landscape. The subject of the proposed area of interest is the appropriate location of excavated flow and impassable pools with unstable water levels during the year and the selection of appropriate accompanying vegetation. The work also offers information on possible financial resources for the proposed measures.

Geobiocenologické mapovanie k.ú.Kojatice ako podklad starostlivosti o krajinu
Polák, Jozef
This work deals with differentiation in the country geobiocenology conceived and care for significant natural features in a rural country. At the beginning it was necessary to gather literature characterizes natural conditions, development and current status of land use mapping of the territory. The main part was setting up a network of geobiocenology areas, characteristic types of the geobiocen and habitat types. Based on this knowledge to process the types of groups geobiocen map and map habitat types. Sozological processing maps, which contains environmentally significant landscape segments, locations of important species of plants, animals and significant trees. Finally, they were designed on the principle of care ecologically significant segments of the country, forming an ecological network.

Reintroduction of butterflies (Lepidoptera)
Štochlová, Tereza ; Sedláček, Ondřej (advisor) ; Straka, Jakub (referee)
The thesis deals with one of the active means of conservation - reintroduction. By this ap- proach, organisms are released in their historical range from which they have disappeared. Re- introductions typically concern vertebrates, that is, however, why this thesis focuses on a group of invertebrates - butterflies (Rhopalocera). The main aim of this work is to carry out a research of previous experiments, evaluate used methods and discover the best way to proceed with reintroduction of butterflies. This process contains many important steps. Firstly, a suitable species must be chosen, that means one that is declining and has limited dispersal abilities. Secondly, an appropriate habitat for releasing organisms must be found - host plants ought to be sufficiently abundant and the area big enough. If the habitat quality is not satisfactory, it can be achieved through management, most commonly by planting host plants, mowing or grazing. Next step is choosing the right donor population. It should be stable, genetically variable, and genetically and ecologically related to the original extinct population. After transfer and release of sufficient number of organisms, it is crucial to carry out a long-term monitoring of the newly formed population and to modify its management when necessary.

Synthesis of digital landscape surface data
Šebesta, Michal ; Kahoun, Martin (advisor) ; Křivánek, Jaroslav (referee)
A procedural generation of landscapes often meets a need for real spatial data at finer resolution that data available at the moment. We introduce a method that refines the spatial data at the coarse resolution into the finer resolution utilizing other data sources which are already at the better resolution. We construct weighted local linear statistical models from both the coarse and utility data and use the by- models-learned dependencies between the data sources to predict the needed data at better resolution. To achieve higher computational speed and evade utility data imperfection, we utilize truncated singular value decomposition which reduce a dimensionality of the data space we work with. The~method is highly modifiable and its application shows plausible real-like results. Thanks to this, the method can be of practical use for simulation software development.

The effect of management on biodiversity of forest ecosystems - epigeic beetles on selected habitats of Písecko
STLUKA, Petr
Communities of epigeic beetles were studied on three forest habitats with the different forms of management in South Bohemia area, Písek district, close from Zátaví village. Selected areas were located in territory of Zátavský forest. There were these habitats: clearing, young spruce forest stands (age 6 years) and spruce forest (age 50-70 years). The method of pitfall trapping was used for biological material capture. There were 1813 specimens and 63 species of epigeic beetles trapped and determined. The highest number of species and individuals was found in spruce young forest habitat (43 species, 786 specimens), than followed spruce mature forest habitat (26 species, 550 specimens) and glade habitat (35 species, 477 specimens). Most species of epigeic beetles from 63 aggregate number of species was classed like eurytops. There were also 15 adaptable species determinated and it was found 1 genus of relict from I. degree too. It was found that spruce forest, which seems like more mature in terms of succession than young forest or glade, had no highest number of species and individuals. Conversely the largest number of species and individuals was found in spruce young forest. Index of antropogenic influence proved relatively strong antropogenic effect all studied habitats in terms of epigeic beetles. Communities of beetles were least affected in spruce forest, than followed young spruce forest and glade. From this point of view, intensity of management had the most effect on glade´s communities of beetles. Mature spruce forest had the least antropogenic influence on communities of beetles.
