Žabovřesky Meadows
Markevičová, Vendula ; Kyselka, Mojmír (referee) ; Mléčka, Jan (advisor)
Žabovřeské and Komínské meadows are divided acording to their names, but in the real landscape it is just only fluent space of large river valley. The space was created by river fo ages, so I let the space to float with the river. All important division of the space are done in parallel with the river, that itself classife the calm, narrower and more familiar right bank and more open, larger left bank of the river. The river shaped the linear charakter of the park and in the same time identify the circle – the space of stop in. The superficies of the area: 141,1 ha.

Loss of valuable meadow biotopes in connection with the construction of new buildings
Nikodýmová, Amálie ; Křenová, Zdeňka (advisor) ; Bílá, Karolína (referee)
- AJ A serious problem of nature protection in Šumava is the problem of the gradual loss of traditionally farmed meadows, which are the objects of protection of the Natura 2000 system in SAC Šumava. Meadow biotopes in this area are decreasing mainly as a result of their encroachment by construction projects. The Šumava National Park Administration, as the competent state nature protection authority, does not have a database that would record the exact loss of meadow biotopes in SAC Šumava in connection with construction. The absence of this information represents a serious obstacle of the state administration of nature protection. As part of this bachelor's thesis, a search of methodological procedures used for the protection of grassland biotopes in large Natura 2000 sites will be carried out. Special attention will be paid to the occupation of biotopes in connection with construction. Part of this thesis will be also the testing of the methodology for the evaluation of meadow biotopes encroachment by construction in EVL Šumava. Key words: Natura 2000, biodiversity, meadows, development

Effect of mowing technique on the quality of cutting, condition and composition of grassland
PETRÁŠ, Marek
The aim of this work is to assess the influence of mowing technology on mowing height, mowing uniformity, cut quality and botanical composition of grasslands. To achieve these goals, two meadows were selected in the cadastral territory of Bukvice near Trhové Sviny in 2022. The first selected meadow was mowed with a rotary disc mower. The second selected meadow was mowed with a rotary drum mower. The botanical composition was recorded for all monitored meadows, and the water and nutrient regime was determined. Before mowing, the condition of the mowing mechanisms, the set mowing height and the condition of the mowing blades were monitored. After cutting, the actual height and uniformity of the stubble, biomass production, and the amount of remaining uncut biomass were monitored. The quality of the cut was evaluated.

Možnosti využití travních porostů v rámci agrolesnictví
Macek, Libor
The bachelor's thesis deals with the use of grasslands with a focus on grasses and clover in agroforestry systems. The first part describes the agroforestry itself – its characteristics and significance. Furthermore, emphasis is placed on woody plants suitable for agroforestry systems, especially in the conditions of Central Europ, as well as on their production and non-production functions. The most suitable representatives are for example, walnut (Juglans), poplar (Populus), but also less economically used representatives, such as cherry (Prunus) or rowan (Sorbus). At the same time, agroforestry is divided into certain units, which are characterized by their functions, both in the tropics and in Europe. The most typical systems in Europe are mainly silvopastoral systems, but also increasingly used alley cropping on arable land. The second part describes various agroforestry systems using grasslands as well as practical examples of functioning systems in different climate zones. Attention is also paid to individual members of the family Poaceae and Fabaceae suitable for their characteristic properties in these systems. The most important for shading appear to be tolerant representatives such as Agrostis stolonifera L. or Festuca arundinacea Schreb. from the Poaceae family or Meadow clover (Trifolium pratense L.) from the Fabaceae family. Possible interactions related to the coexistence of woody plants, grasses and clover, such as competition and allelopathy, are also not neglected.

Possibilities to restore seminatiral meadows in post industrial sites.
Kolářová, Petra ; Frouz, Jan (advisor) ; Tátosová, Jolana (referee)
The post-industrial sites (brownfields) are sites which were devastated and abandoned by industrial production (generation areas, dumping grounds, mining areas…), but buildings and paved areas abandoned by agricultural production, too. On the other hand on these very disturbed places, primary succession, may leads to recovery of valuable ecosystems. It shows the potential of these areas for the restoration of valuable near natural ecosystems. One of the possibilities how to use these areas could became establishing species rich meadows rich, which could return to the meadow ecosystem his original function. They could benefit from oligotrophic status, at least some of these sites, too. The aim of this work is to summarize the information about factors which influence structure and diversity of meadows, their restoration and assess chance post-industrial sites utilization for the recovery of species rich meadows. Finally results of experiment about restoration of species-rich meadow ecosystems on mine spoil dumps in the surrounding of Sokolov are represented.

Effect of floral rewards on specialization of hoverflies (Diptera, Syrphidae) in meadows of Železné hory
Filip, Jan ; Tropek, Robert (advisor) ; Keil, Petr (referee)
Traditionally managed temperate semi-natural meadows are generally considered as one of the most diverse habitats worldwide. During the past decades, management changes and abandonment of meadows pose serious threats to communities of both flowering plants and pollinators. However, the extent to which are pollinators affected by changes in floral resources still remain unknown. To investigate the effect of floral resources on visitation specialization, species richness and abundance of hoverflies, pollination networks from 13 meadows in the Železné hory PLA were constructed and analysed. Moreover, patterns were recorded on two spatial scales, in transects and in the whole meadows. To specify the specialization of hoverfly pollinators, unvisited plant species and all resources present on a site (transect/meadow), offered by plants as floral abundance and nectar rewards, was added in the networks. Relationships between plant species richness, floral abundance and nectar sugar production were positively correlated with visitation specialization of hoverflies on the meadow scale. Species richness and abundance of hoverflies was affected by floral resources on the transect scale, unlike the specialization of hoverflies. The usage of extended network indices may act as an improvement towards the better...

Possibilities of object based image analysis for monitoring of meadow vegetation and management in the Krkonoše Mountains National Park
Dorič, Roman ; Kupková, Lucie (advisor) ; Potůčková, Markéta (referee)
Possibilities of object based image analysis for monitoring of meadow vegetation and management in the Krkonoše Mountains National Park Abstract The main aim of the thesis was to evaluate possibilities of Object Based Image Analysis (OBIA) of WorldView-2 satellite image data and aerial optical scanner for meadow vegetation and managment types classification in Krkonoše Mountains National Park. The classification was based on legend prepared by botanist of the national park. The second goal was to compare classification accuracy of Object Based Image Analysis and neural net classification method that was used by Pomahačová (2012) for the same area and the same WorldView-2 data. OBIA for meadow vegetation was conducted using SVM algorithm and "Decision Tree" algorithm. The classification accuracy was estimated using reference points from the field. The thesis puts the requirements (optimal parameters and conditions) for successfull object based classification of mountain meadow vegetation into a new perspective. Key words: Object based classification, meadows, WorldView-2, aerial optical scanner, SVM, KRNAP

Monitoring of ecological conditions and occurence of selected legume species and herbs in grassland
JAKŠOVÁ, Marie
Understanding the importance and the possible use of clover in permanent grassland is very important. Their irreplaceable role in nitrogen fixation and enrich the soil of this essential element is very important. The significance of herbs in grassland is also significant, even though its importance is often overlooked. Herbs not only serve as indicators of habitat conditions, but also can improve the quality and palatability of forage. If we know the herbs and legumes and their habitat requirements will help us select the most suitable way of management and the effective use of the potential of the habitat. The aim of the thesis was to observe conditions of use and the occurrence of selected legumes and herbs in TTP. Research can therefore conclude that the biggest influence on the composition of the grassland have ecological conditions. Way management can to some extent affect the crop themselves, but the biggest factor remains what we can not influence and that is the weather. The results also shows that the richer pastures.
