Invasive species mapping beyond activities of Nature Conservation Agency
Joščáková, Aneta ; Pergl, Jan (advisor) ; Chobot, Karel (referee)
Invasive species are a persistent problem in environmental protection. In order to grasp invasions properly and especially for their effective management, it is necessary to have good information on the occurrence of invasive species. However, mapping activities to date have mostly been narrowly focused, mainly on sites of conservation interest and selected flagship species. Records from these activities are now concentrated in the Nature Conservancy Central Register of the Nature Conservation Agency of the Czech Republic. This database is currently the best data source on the occurrence of invasive species in the Czech Republic. Nevertheless, it still does not contain a satisfactory number of records. The largest gaps are in areas outside the interest of nature conservation. Mapping of these areas can be done through citizen science, which is specifically very suitable for mapping invasive species. Another promising but rarely used source of data on the occurrence of invasive species is the grey literature, the potential of which has been explored in this bachelor's thesis. Thesis and professional surveys organised by the county were examined. It was shown that all the studied works and surveys contained large amount of good data on the occurrence of invasive species. Unfortunately, these data...
Ecological aesthetics of freshwater wetlands: the importance of environmental heterogeneity and biodiversity
Hájková, Tereza ; Hořák, David (advisor) ; Chobot, Karel (referee)
Ecological aesthetics study landscapes through different interactions of ecological and aesthetical properties of different environments. Ecological aesthetic of wetlands are quite specific, their ecological value can be extremely high, and they bring people many benefits Despite that, wetland ecosystems can be viewed quite negatively. Wetlands support a large number of species, some of which are wetland-dependant species. Wetlands are very variable, and they can have interesting spatial diversity. Environmental heterogeneity encapsulates both these properties of a landscapes, aesthetic, as well as ecological. And that is the reason why it is a crucial aspect of ecological aesthetic.
