Effect of management and soil conditions on the frequency of field vole (Microtus arvalis) and common mole (Tapla europaea) in grassland
ŠPILAUER, Tomáš
This thesis examines the influence of grassland management and soil conditions on the occurrence of field voles (Microtus arvalis) and common moles (Talpa europaea) in grasslands. Literature review covers soil conditions, meadow management practices, and descriptions of the two species. The practical research involved ob-serving and counting molehills and field vole burrows on defined plots. All new molehills and burrows on the pasture and meadow were recorded. The study was conducted on two plots in two periods: Plot 1 (May 2023 - March 2024) and Plot 2 (February 1 - March 22, 2024). Differences in management methods and soil conditions affected the occurrence of the animals. Burrows were more prevalent in meadows, while molehills were more common in pastures. Waterlogged meadows had no burrows. Molehill occurrence was influenced by vegetation cover and soil disturbance. Most molehills and burrows were observed between November 2023 and the end of March 2024.

Typological classification and categorization og grasslands in selected area and recommendation of sutable grassland management
KADLECOVÁ, Jana
The aim of this thesis was to create the botanic snap of the chosen locations, which were meadows, grasslands, pastures and also fallow grass areas, to determine the area coverage of three main agrobotanic species i.e. grass, herbs and clover, to process it with the statistcal software and determine the method and intensity of use and fertilization of individual locations and suggest the suitable prato-technical methods. The cenological structure of the locations has been observed and described using botanic snaps. The prato-technic method used were documented for each of the locations and evaluated the influence on the cenological structure. The research was performed in locations Vřeskovice, Čeletice, Městiště in the region Pilsen, former district of Klatovy. In each location the botanic snaps were taken from 3 areas of about 5 x 6 meters each. There were determined the area coverage of grass, herbs and clovers and calculated the mean indication value of humidity. Mean indication value of humidity is the parameter usable for determination of permanent grassland management and utilization. The data from the research was elaborated in software MS Excel. I recommend to manage the analyzed permanent grasslands as follows: 1. The meadow Vřeskovice behind the sewage cleaning station - additional sow of perennial rye grass, meadow clover and white clover. 2. The meadow Mstice - total recovery alternatively conservative prato-technic measures - manure fertilization for about 20t/ha and additional sow of meadow and white clover and grass - red fescue, blue grass and perennial ryegrass. 3. The meadow above the transformer station Vřeskovice - keep on current management od additional clovers sow. 4. The pasture Čeletice grazed by horses - keep on current management or additional sow of red fescue, tall fescue and timothy grass. 5. The meadow Městiště with combined utilization by cattle pasture and mowing - keep on current way of use. 6. The pasture Vřeskovice grazed by cattle - keep on current utilization or additional sow meadow and white clover. 7. The pasture Vřeskovice grazed by sheep - keep on the current utilization, in future after the reduction of dangerous knapweed to decrease the amount of pastured animals. 8. The fallow meadow Vřeskovice behind Petrovický neither mowed nor pastured - proposed mulching twice a year for about 1 or 2 years, then pasture or pasture of extensive cattle breed (Galloway) or sheep or periodical mowing once or twice a year. 9. The fallow meadow Vřeskovice trench at the farmhouse - leave as a fallow meadow improves the biodivesity, optionally to mow once or twice a year from estetical reasons.

Effect of different management practices on grassland
SEJPKOVÁ, Jana
The aim of this thesis is to assess the impact of farming on grassland and assess the frequency of use of grassland on yield and quality of forage biomass. A part of this thesis is also a recommendation of possible management changes of evaluated grasslands. Botanical inventory surveys were conducted on agricultural lands Bílovské zemědělské a.s., in the northern Plzeň region. There have been selected three sites, two meadows and one pasture vegetation. The comprehensive analysis of the stand composition was created by agrotechnology of meadows. An important part of this thesis is to assess the impact of different grassland management practices with regard to their economic, social and ecological importance.
