Vegetation dynamics on fallows
 Entová, Martina ; Fabšičová, Martina (advisor) ; Procházka, Tomáš (referee)
The bachelor thesis is concerned with problems of abandoned fields. Fields are very important ecosystem for mankind. Abandonment of agricultural land and formation of fallows happend in last decades. Social and political changes can be the reason of fields abandonment as well as economical changes or changes in ecological conditions. The fallows are good model for secondary succession studies, but they can have many other funcitons in a land. Succession doesn't always proceeded in the same way, it can be affected for example by historical land use, species pool or environmental factors. Permanent plots or space for time substitution can be used for succession research. The rich reserve of seeds in the seed bank is typical for fallows. That can be described by several methods: elutriation, cloth bag, flotation or seedling emergence. Many scientists from the Czech Republic and also from all over the world are interested in fallow research. My MSc. thesis is presented at the end of this bachelor thesis. The comparison of actual vegetation and the soil seed bank of fallows in Podyjí National Park will be the aim of this work. Usage of ploughing as a possible management for creation and preservation of a rich fallow associations will be studied.
