Impact of Different Lawn Maintenance on Terrestrial Invertebrate Biodiversity
Klán, Jan ; Říhová, Dagmar (advisor) ; Škodová, Jana (referee)
This paper focuses on differences in the composition of invertebrate communities in grasslands with different management of green space management. It was carried out on four research plots with different management types (no-till, regular treatment with a power mower, treatment with a scythe, treatment with grazing). The main objective of the work is to demonstrate, using a sample of captured spiders, centipedes, millipedes, earwigs, and leafhoppers, which form of grassland habitat management is the most appropriate in terms of biodiversity richness. Other sub-objectives were to obtain local data on the variability of soil moisture in the study plots, air humidity and temperature. These values will illustrate an idea of the habitat of the captured animals. In terms of biodiversity, the grazed habitat proved to be the richest (a total of 84 species captured). This was followed by the no-mow habitat (83 species), mowed (76) and finally mowed with a mower (74). Mowed habitat was the poorest. In all habitats, the highest number of spider species was always captured, followed by crickets, and an order of magnitude fewer millipedes, centipedes, millipedes, and starlings were captured. One species of chrysalis was captured, which is listed on the Red List of Threatened Species of the Czech Republic. This...
The comparison of ecological and functional characteristics of species Filipendula vulgaris in rich species meadows of White Carpatian Mountains: Analysis of growth and assesment of carbohydrate storage by method of liquid chromatography
OLIVA, Ivo
Filipendula vulgaris is not dominant species undemanding on locality. The biomas of studied species was rising as well as the biomass of competitors in time. Influence of surroundings biomass was inconclusive. The aim of this study was evaluation of dynamism of total nonstructural carbohydrates (TNC) in species F. vulgaris during vegetation season. It was tested influence of competitors on plants and it was included influence of mowing too. TNC in roots didn´t vary significantly. After mowing plant quickly regenerated.

KLEČKOVÁ, Hana
Lathyrus niger is a persistent herb typical for deciduous forests, which produced a lot of biomass, especially under ground. The aim of this study was evaluation of dynamism of total nonstructural carbohydrates (TNC) in roots and analysis of growth in species L. niger during vegetation season. It was tested influence of biotope (forest or meadow), including influence of shading plants in forest, next influence of mowing on plant{\crq}s growth and on change of content of TNC.
Changes of vegetation composition in hilly country forests depending on the application of historical forms of management
Nechanská, Denisa ; Boublík, Karel (advisor) ; Frouz, Jan (referee)
The aim of my study is to determine the influence of historical management practices on the camposition of vascular species in hilly country forests on the Vysoká stráň hill in the Bohemian Karst Protected Landscape Area in the Czech Republic. My thesis is divided into two parts. The first part of my thesis describes influences of forest management on the herb diversity from different scientific studies. There is some information about the influence of herbivorous grazing, pollarding, litter raking and fire. Secondly provides a case study dealing with the influence of historical management on the vascular species composition in the forest understory. My experimental area was divided into 32 treatments, where three different ways of historical management were used - mowing of the understory vegetation, litter raking and the combination of mowing and litter raking. The fourth area was a control treatment. Change in the herb diversity depending on a time is statistically significant but changes in the herb diversity depending on different ways of historical management are statistically insignificant. We detected a distinct decline in the herb diversity during our experiment, also on the control treatments. The main gradient of vegetation points from mesophilous acidophytes to species characteristic...
Effect of grazing and mowing on vegetation of dry grasslands
Pechová, Tereza ; Münzbergová, Zuzana (advisor) ; Čiháková, Kateřina (referee)
Grassland communities are natural part of our landscape. They were mostly created or maintained by human. If we leave them to their natural development they will disappear. Today grazing or mowing is recommended as an appropriate management. This work is an answer to the beginning of the grazing and mowing management in NPP Kaňk near Kutná Hora. Its goal is preparation for the monitoring of grazing and mowing, which will be in progress in this locality since year 2010.
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 management on the diversity and establishment of plants in the Giant Mountains
Trejbalová, Lenka ; Krahulec, František (advisor) ; Březina, Stanislav (referee)
Meadows, as an integral part of the Giant Mountains, depend on regular management, without it they can get degraded. The aim of this thesis was to evaluate the impact of different types of management (mulching, mowing with or without fertilization) on change in coverage, biomass and establishment of plants. The experiment took place in years 1997-2011 on the site called Sněžné Domky in Giant Mountains on 3 sites which differ in humidity and trophy. The effect of management on vegetation change was statistically conclusive. Mulching was preffered the most by Geranium sylvaticum, mulching and fertilization was preffered especially by these species: Holcus mollis, Alopecurus pratensis and Crepis conyzifolia. Mulching and no fertilization: Achillea millefolium. Avenella flexuosa preferred particularly mowing. Mowing and fertilization was preffered by Festuca rubra, Luzula luzuloides, Anthoxanthum odoratum, Agrostis capillaris, Veronica officinalis and Hieracium lachenalii. Mowing without fertilizazion was preffered by Potentilla erecta. The effect of management on the amount of biomass appeared statistically inconclusive (except for amount of old biomass). Biomass is more correlated by the weather and the trophy of the site than the type of management. The effect of management on establishment of plant...
