The impact of agricultural and anthropogenic activities on Lhotický and Vitický stream in the watershed of the river Želivka
 Jakešová, Helena ; Charvátová, Helena (advisor) ; Petrů, Anita (referee)
Every small watercourse is part of the balance in nature. Human activity affects the quality and the physico chemical composition of water. Man is changing riverbeds and hydrological conditions of the environment. This bachelor thesis evaluates the chemical composition of experimental flows of the Lhotický stream and the Vitický stream of the Želivka river basin in the Křemešník Highlands. Doing field research, monitoring and evaluating the results of water samples is carried out to find the influence of human activities on the quality and composition of water. The area is anthropogenically influenced mainly by sewage water in the municipalities where sewage treatment plants are missing. Agricultural activity causes contamination along the entire length of the flow. The streams do not have a treated bed, overflowing is possible in numerous floodplains, the impact of pollution is mitigated by riparian vegetation.The monitored indicators rank the experimental flows into the lowest class. In the area, maintaining a healthy ecosystem is possible.

Biotope mapping of locality Branský les, South Bohemia, in the context of planned expansion of peat extraction
 Klimešová, Sandra ; Petrů, Anita (advisor) ; Charvátová, Helena (referee)
The goal of this thesis was to map actual habitat distribution in the locality of Branský les II. in Třeboň. The locality is influenced by adjacent peat extraction. The purpose of this mapping was the identification of natural habitats and habitats influenced human activity. At the same time, detection of presence of rare or threatened species of flora and assessment of the expanse of area influenced by adjacent extraction. In 2015 a data collection was performed and the results were evaluated by the Habitat Catalogue of the Czech Rebublic and Handbook of Habitat Evaluation. In the study area there obvious degradation of stands mainly because of drainage. A ratio of natural habitats compared to anthropologenic habitats is minimal. Nevertheless, the vegetational attributes of the locality match with the habitat L10.2 pine mire forests with Vaccinium and within Natura 2000 network belongs to so called priority habitats. As a suitable way of restoration of peat bogs natural habitats is possible to apply a method of blocking a drainage canals or leave a peat bog to natural cyclical development
