Historický výskyt zubra evropského na českém území a jeho význam pro okolní krajinu / Historical Existence of European Bison in the Czech Geographical Region, and its Significance to the Surrounding Landscape

Řezáč, Tomáš January 2018 (has links)
The subject of this diploma thesis is an analysis of the historical existence of European bison in the Czech geographical region and an evaluation of the significance of its presence to the surrounding landscape. The goal of the thesis is to depict bison population changes in the Czech territory over time and the meaning of efforts to reintroduce the bison into its natural habitat. An important part of the work then will be the preparation, realization and evaluation of two excursions during which students go for European bison directly into the field.

Hodnocení vegetačních pozůstatků někdejšího osídlení ve vybrané příhraniční oblasti / Evaluation of vegetation remnants of former settlements in selected border areas

KALNÁ, Eva January 2010 (has links)
Eva Kalná, 2010:Evaluation of vegetation remnants of former settlements in selected border areas. It was chosen region Zhůří for this work, which is one of the displaced villages at Šumava Mountains, which was part of the Dobrá Voda military training area. First, the work is devoted to the history of the village and then to changes in vegetation both directly and indirectly influenced by humans. The part of theme of this paper is primarily exploring areas of interest in terms of plant species, providing evidence of former settlements and making photographs and map outputs for each species found. The next theme is the evaluate of using the area from 1949 to the present, which over decades has fundamentally changed. Work also focuses on comparisons between the state of use from the 1949 today state habitat.

Změny krajinného pokryvu a využití krajiny bývalého VVP Ralsko po roce 1990 / Changes in land cover and landscape use in the former military training area Ralsko after 1990

Tvrzník, Lukáš January 2017 (has links)
This diploma thesis deals with the change of the landscape cover and the use of the landscape of the former Ralsko military training area after 1990. The former VVP Ralsko is located on the area of 250 km2 between Česká Lípa, Stráží pod Ralskem and Mnichovo Hradištěm. Most of its territory lies in the Liberec region and only its southern part reaches the Central Bohemian region. After the departure of the Soviet troops in 1991, the military training area was abolished and on 1 January 1992 the village of Ralsko, which currently has 171 km2 , was formed by merging nine municipalities in its former territory. The town of Ralsko is thus an area with the largest area in the Czech Republic. Between 1993 and 2004, the former military area was decontaminated, during which more than 120,000 pieces of ammunition were found and destroyed. Decontamination of contaminated soils and groundwater is ongoing. Some former military buildings are currently commercially used as warehouses for raw materials. The Military Airport at Hradčany is partly used for sports purposes, and a range of rare game species has been set up in the area of the Židlov tank space, of which the most interesting is the European Tooth (Bison bonasus). In the first part of the thesis there is a search of specialized literature dealing with...

Vliv činnosti armády na sukcesi společenstev terestrických členovců v CHKO Brdy / Influence of military disturbances on succession of arthropod communities in Brdy

Palivcová, Lucie January 2018 (has links)
The thesis aims for relationship between military-caused disturbance intensity and species richness, conservation value and composition of arthropods communities in the Brdy Mts. In the Brdy abandoned military area (MTA), a highly heterogeneous habitat mosaic developed by the long-term influence of military disturbances on two shooting areas of Jordán and Tok. The habitats range from strongly disturbed sites with sparse vegetation, through heterogeneous growths of Erica and Vaccinium in moderately disturbed sites, to sparse woodlands in the least disturbed sites. Based on the shooting areas history reconstruction, 24 study plots of 4 categories of different disturbance intensity were selected in both shooting areas together. Standardized sampling of seven groups of arthropods was performed in summer 2017 by pitfall traps, yellow pan traps, and light traps. More intensive disturbances positively influenced species richness of Aculeates and conservation value of spiders and beetles, but negatively affected species richness of moths. Simultaneously, the intensity of disturbances affected community composition of spiders, moths, beetles, Aculeates and Orthopteroids. Endangered species mostly affiliated to the more intensively disturbed plots. This results should be helpful in understanding of influence...

Vlastnosti biotopů zodpovědné za atraktivitu vojenských cvičišť pro ptáky: případová studie z vojenského újezdu Hradiště / Habitat characteristics accounting for the attractiveness of military training areas for birds: a case study from the Hradiště military training area

Hernová, Jana January 2020 (has links)
Military areas are extraordinary biodiversity-rich due to limited economic activities and a specific way of using the areas for military training. Previous research has also revealed their positive influence on bird species diversity, this applies to endangered species in particular. However, the exact biotope characteristics attracting birds are insufficiently known. In this regard, I expected an important role of heterogeneity of the environment. The aim of the thesis was therefore: (I) to find out the difference of environmental heterogeneity between a military area (MA) and the surrounding landscape, both in a forest and a non-forest sites, (II) to find out what biotope characteristics attract birds in open landscape and (III) what characteristics attract birds in forest. Fieldwork took place in a still active MA of Hradiště and neighboring controls of Bochov and Ostrov. In total, 80 study plots were surveyed for representation of individual biotopes (39 types in total) and the number of fragments of woody vegetation. Data on bird species richness were taken from the thesis of Bušek (2015), surveyed birds at identical study plots and calculated total number of bird species and the number of endangered bird species at each plot. The open landscape of MA has, compared to the surrounding cultural...

Jak se liší druhové bohatství a početnost ptáků mezi vojenskými výcvikovými prostory a okolní krajinou? Případová studie z vojenského újezdu Hradiště / How do bird species richness and abundance differ between military training areas and surrounding landscape? A case study from the Hradiště military area

Bušek, Ondřej January 2015 (has links)
Since the beginning of the 20th century human land use changed drastically in Central Europe. These changes included: homogenization of the landscape mosaic, intensification of agriculture, urbanization and land abandonment. In turn, these changes affected bird species and perhaps most significantly manifested in population decline of open habitat birds. Therefore, it is important to investigate sites, which were not affected by the changes mentioned above, such as military training areas (MTAs) - places dedicated to training of armed forces. Previous studies have shown that MTAs seem to host remarkably high bird diversity and abundant populations of bird species of conservation concern. This may be caused by two major factors. First, closure of MTAs to all human activies besides military training spared them of the landscape changes mentioned above. Second, the military training itself produces a very heterogeneous habitat mosaic that allows coexistence of many species with different ecological requirements. To my knowledge, no study compared bird assemblages between MTAs and surrounding landscape directly. At the same time, such data are crucial to assess the value of MTAs for bird conservation reliably and, as a consequence, they enable to think more deeply about mechanism generating this value....
