Are former common pastures a significant part of protected areas?
Kosová, Barbora ; Křenová, Zdeňka (advisor) ; Härtel, Handrij (referee)
Former common pastures show a higher biological value than the surrounding landscape and they usually represent areas of conservation value. The aim of this thesis is to find out whether the state nature protection of the Czech Republic reflects this fact. For this purpose, 210 small protected areas in six districts in three regions, namely Cheb and Sokolov districts in Karlovy Vary region, Česká Lípa and Jablonec nad Nisou districts in Liberec region, and Kroměříž and Zlín disctricts in Zlín region were analyzed. The former common pastures were located within the boundaries of the small protected areas according to the historical maps of Stable Cadastre from the first half of the 19th century. To determine biotope diversity of analyzed areas the Natura 2000 biotope mapping was used. Data from the species database were used to compare species diversity of the studied protected areas. In conclusion, the former common pastures were located in 30 out of 210 small protected areas and on average covered 3,6 % of the protected area. Above average values were found in the districts of Zlín region. Higher biotope diversity of the former common pastures was confirmed, as well as higher biotope diversity of protected areas, in which former common pastures were located. The differences in the species...

Former common pastures: Biodiversity refugia in the changing landscape of Central Europe.
Vosmíková, Alžběta ; Křenová, Zdeňka (advisor) ; Reif, Jiří (referee)
The diploma thesis evaluates the current status of former common pastures of a study area in southwestern Bohemia. The thesis aims to demonstrate the high biological value of former common pastures and determine predictors of their preservation. For this purpose, a vector layer of former common pastures containing 668 segments was created. This layer was compared with other map layers (aerial images, consolidated layer of ecosystems, Natura 2000 mapping, species database) and various field observations. A database describing a current status of former common pastures was created and 49 preserved pastures were selected, according to predetermined criteria. Comparison of data from the common pastures and the sorrounding landscape confirmed higher biological value of the pastures. They have significantly higher habitat diversity, described by frequency and composition of Natura 2000 habitats. Several ecological and descriptive parameters were tested to find predictors of pastures preservation. The results showed that signifiant predictors of the pastures preservation are ecological parameters (i.e. number of Natura 2000 habitats, number of protected species recorded in database) and also descriptive factors (i.e. size of the pastures, shape, distance from municipality). Key words: common pastures,...
