Hodnocení managementu pastvy ovcí v chráněných oblastech
Trojanová, Eva
The diploma thesis Evaluation of Sheep Grazing Management in Protected Areas deals with the use of grazing for sheep nutrition, sheep ethology, especially the influences that affect grazing behavior, and the use of grazing in the maintenance of vegetation in the National Nature Reserve of Mohelno Serpentinite Steppe. The 2018 grazing season in the National Nature Reserve of Mohelno Serpentinite Steppe took place from 23rd April to 25th May 2018 and three ethological observations were taken during this grazing season. On 9th, 17th and 21st May, the activities of the herd were recorded – namely lying, standing, walking and grazing. On the first observed day (May 9), the activities were represented in the ratio: grazing 37.50%, walking 12.35%, standing 5.81% and lying 44.34%. On the second day of observation (May 17), grazing took up 39.15% of the total observation time, walking 12.27%, standing 18.95% and lying 29.62%. On the last day of observation (May 21), the ratios of daily activities were: grazing 34.07%, walking 10.25%, standing 9.37% and lying 46.31%. Activities were also recorded depending on the grazing area, and the effect of air temperature on sheep behavior was investigated. The results are processed in charts and graphs in the appendix.

Horses and vegetation
Třeštíková, Tereza ; Herben, Tomáš (advisor) ; Mládek, Jan (referee)
Many studies show that large herbivores can have an important impact on the composition of vegetation. With the establishment of a year round, low density grazing regime, plant ecologists and nature managers expect that through selective grazing, herbivores will create a mosaic of different vegetation communities varying in structure and plant species composition. It is believed that such a mosaic in the end will guarantee a high degree of biodiversity. Grazing will, therefore, seem to be a suitable means to maintain grass. Also important is the ability of herbivores affect vegetation through endozoochory. In this thesis I have tried to find out what species of diet horses prefer regarding to plant species and what plant species they can spread through out endozoochory. I have compared this knowledge with the composition of pasture and meadow vegetation at the researched locality in Malenice and Hoslovice. With the purpose of finding out the preferences I established spots where I registered data on vegetation before pasture and the time intervals during the pasture. Afterwards, I researched the amount of sprouts and the composition of seedlings in excrements that I let germinate. I had to create phytocenologic shots from the pastures and meadows to compare the species of composition of grazed and...
