Tesárková, Monika ; Pešková, Vítězslava (advisor) ; Čížková, Dana (referee)
The thesis aims to evaluate the state of health of tree species growing in Karlštejn National Nature Reserve, with the main focus on ligniperdous fungi found in this location.
Data were gathered in two experimental sites near Hostím and Bubovice villages, situated in the protected landscape area of Bohemian Karst (Český Kras). Tree species were inventoried in both designated sites and list of individual species of wood decaying fungi was put together. Furthermore, the state of health of tree species was evaluated according to crown defoliation and abiotic damage.
The thesis also briefly describes the history of Bohemian Karst Protected Landscape Area and other related themes climatic and soil conditions, including geological and geomorphological characteristics of this region that significantly influence the natural character of the territory, including occurrence of ligniperdous fungi.
The examination and subsequent controls of the selected sites took place once a month in period lasting from April 2015 to November 2016, revealed that only common species of wood decay fungi are found in the area of Karlštejn National Nature Reserve, which is part of Bohemian Karst Protected Landscape Area. These fungi are commonly present in the territory of the Czech Republic, therefore no unusual or new species of wood rotting fungi were found. The Korovitka (Diatrype) is the most widespread decaying fungi in both experimental plots, but the only one found fungal patogen Sphaeropsis sapinea, which in recent years has spread further and causes death and drying of pine trees has an economic importance for this area. Due to the good health of trees were found no major differences in the defoliation of trees, up to the aforementioned black pine attacked by fungi Sphaeropsis sapinea. There was observed defoliation from 45 to 100 %. There was no significant damage abiotic species found in the areas under examination.
