The European beaver (Castor fiber) in CHKO Blanský les
PRAŽÁKOVÁ, Ema
The main aim of this thesis was to research the ecology of the European beaver (Castor fiber), history and distribution of the species in the world, Europe and the Czech Republic. The basic methods of determining the dispersal and abundance of the species in the inhabited area were also described. Also contained was the mapping of the settlement in the selected area in the central part of the Czech Forest Protected Landscape Area, which took place in January and February 2023. The gained information was compared with the results of previous monitoring. The data collected during errands along the shorelines of existing and newly discovered territories showed that the expansion of beaver populations in most of the area is slowly stagnating. Colonisation is currently at a stage where the population is almost constant and unchanging. The typical character of colonisation, as pointed out by many authors, has therefore been confirmed.

Selekce potravy bobrem evropským (Castor fiber) v hospodářských porostech jižní Moravy
Černíková, Karla
The bachelor's thesis deals with the selection of food of European beaver (Castor fiber) in the Tvrdonicko area, specifically in the surrounding stands of six blind branches of the Morava River. Czech and foreign literary sources served as the basis for the literary part of the work. For the practical part of the work, data from the field survey, which took place in the winter period of 2017 and 2018, were used. The most preferred tree species in this area were poplar (Populus sp.), babyka maple (Acer campestre), willow (Salix sp.), ash (Fraxinus sp.) and blackthorn (Prunus spinosa). The beaver preferred the most young stands with individuals of smaller diameters. The damage to the vegetation was very low compared to other localities. The results of this work mostly confirm the information presented so far on the selection of woody plants by a beaver. It also focuses on evaluating the factors that influence food choices.

The story of the European beaver on the territory of the Czech Republic
Kletečková, Aneta ; Kostkan, Vlastimil (advisor) ; Bartoš, Michael (referee)
This thesis deals with the controversial species of the animal, the European beaver, which is perceived very differently in the human society. In the history, this especially protected animal was extincted on the territory of the Czech Republic and actually his activites frequently come into conflicts of human interests so the comeback of beavers is not always welcome. The thesis describes the process of changing situation of the population of beavers in the Czech Republic and important aspect of their existence. The practical part of the thesis is pursued on the research, which is focused on the perception of the problematic issues of the european beaver by the experts in the Czech Republic. This research is based on seven expert interviews and also on the survey. The goal of my research was to gain comprehensive informations about the perception of experts and about their recommendations how to moderate the situation and harmonize the human - beaver relationship. The main contribution of this thesis is the cooperation all key goups of experts and primary the most important is that results from the research can be used as a material for the future expert debates. Key words: European beaver, species protection, experts, nature preservation, Czech Republic

The European beaver (Castor fiber) in the Czech landscape - educational project
PEKAŘOVÁ, Silvie
This bachelor thesis is focused on the formation of an educational program with the topic "The European beaver and his influence on the environment". The work summarizes current knowledge of history, general biology and ecology of this species, as well as information on the impact of beaver on the environment. Further, the educational program with this theme is proposed, in the modifications for the primary, secondary, high schools and university students. Participants of the program will learn about the beaver and its environment. They will learn about his history and about his return to our country. The most important of the educational program is the importance of the European beaver in our landscape and how it affects the surroundings. The tutorial also deals with the relationship between the European beaver and humans. The program was tested in the near the Soumarský most with students of the Ecological and Food High School in Veselí nad Lužnicí.

The population of the European beaver (Castor fiber) in PLA Český les
MARKOVÁ, Kateřina
The aim of this study was monitoring of European beaver in a defined area of the central part of the PLA Český les in order to determine size of the population and its food demands. The monitoring took place in December 2013 and January 2014. The data were obtained during walks along the shore lines of watercourses and areas located in the monitoring area and had form of GPS location recording beaver tracks and signs. These data were transferred into the geographic information system, where individual territories of beaver families were defined using kernel density estimates. The total number of individuals in the monitored area was estimated based on the number of defined territories and the average number of individuals per one family. In total, 15 territories comprising approximately 81 individuals were defined. The most commonly found type of housing was the castle. Beavers used mostly trees genus Salix (37,86 %). Other frequently used genera of trees were Betula (29,04 %), Alnus (17,70 %) and Populus (9,73 %). Most of the trees that were cut had the diameter of 2,6 6 cm (30,45 %) and of 2,5 cm (20,96 %).

Výzkum ekologie a rozšíření‚ návrh managementu populací a záchranných programů zvláště chráněných druhů živočichů: Projekty aktivní podpory ohrožených živočichů v České republice
Agentura ochrany přírody a krajiny ČR, Praha ; Nová, Petra ; Marhoul, Pavel ; Kumstátová, Tereza
Snahou sborníku je pokusit se shrnout dosavadní zkušenosti s aktivní podporou některých ohrožených živočichů a využít je pro další rozvoj a zefektivnění projektů tohoto typu. Realizovaných projektů bylo velké množství, mnohé z nich po sobě nezanechaly žádnou publikační ani jinou stopu, jiné jsou zdokumentovány pouze nedostatečně a nelze je nijak hodnotit. Do hodnocení se tak dostaly zejména projekty hrazené z veřejných rozpočtů, u kterých je stanovena povinnost podání zprávy o realizaci projektu. Hodnoceny byly aktivity realizované od roku 1980, v případě, že byl určitý projekt významný z metodologického hlediska nebo má přímé vazby na současnost, bylo možno zahrnout i projekty starší. Hodnocení celostátně koordinovaných projektů a dále všech, u kterých došlo k jakýmkoliv reintrodukcím. Projekty byly věnovány těmto živočichům: vodní měkkýši, rak říční, motýli, blanokřídlí, ryby, obojživelníci, želva bahenní, ještěrka zelená, ostatní plazi, užovka stromová, hohol severní, drop velký, tetřev hlušec, čáp bílý, moták lužní, puštík bělavý, sova pálená, sýček obecný, sýc rousný, ledňáček říční, netopýři, sysel obecný, bobr evropský, vydra říční a rys ostrovid.
