Řezník, Jan ; Vardarman, Johana (advisor) ; Naděžda, Naděžda (referee)
For several decades is Europe, as well as many other parts of the world, suffering by invasion of Himalayan balsam (Impatiens glandulifera), while mapping of its occurrence has become an integral part of a successful fight with it. For this purpose, the mapping of the plant was carried out in the Site of Community Importance, the Elbe valley in the Northern Bohemia. It was processed by locating of GPS coordinates and subsequent data processing by GIS tools. The aim was firstly to find and interpret the degree of invasion in our area of interest, and also to assess it qualitatively, based on biotopes, where it has occured. As a result, we got a database of information, which along with the mapping outputs, points to fact that major occurrence of Impatiens glandulifera is close to watercourses and human settlements, esspecially in habitats with ruderal vegetation. The work can be used as a source of information for planning and management in the area.
