Čtvrtečka, Tomáš ; Vykouk, Martin (advisor) ; Šmíd, Petr (referee)
This bachelors thesis deals with mapping and finding the way of spreading invasive plant species, particularly Reynoutria japonica, Reynoutria sachalinensis, Reynoutria x japonica, Impatiens glandulifera, Solidago gigantea and Solidago canadensis. Kopistys spoil heap, which is situated in the Most Coal Basin in northern Bohemia near Most, was selected as the area of interest for mapping these invasive neophytes. The thesis also includes information about selected invasive plant species and brief physical-geographical characteristics of the territory. In the area of interest were found only individuals of Reynoutria japonica, at 10 sites, as well as individuals Solidago gigantea species in 16 habitats and the last species was Solidago canadensis, which occupied the largest number of sites, a total of 78. It was found way of spreading of the invasion in the territory, distances from each distribution vector was recorded and biotopes, in which invasive plant species were found, was described.

Heřmanová, Lucie ; Pěknicová, Jana (advisor) ; Markéta, Markéta (referee)
Bachelor's dissertation is orientated towards issue of presence of invasive plants. In chosen part of PLA Kokořínsko proceeded mapping of current extension of chosen invasive kinds of goldenrod (Solidago) and knotweed (Reynoutria). The goal of this bachelor's dissertation was mapping of affected invasive plants and consecutive evaluation of results, when there was investigated, which biotope affected kinds colonize. As complementary analysis there was investigated preference of type of soil of individual kinds. Most often there was affected S. canadensis, which also covered the biggest area. From final survey resulted which biotopes and ecosystems the invasive plants mostly invade. From the data is also possible to see that invasive weeds colonize most frequently man-made affected habitats and brown soil is preferred kind of soil.
