My thesis deals with the collecting of basic information and data on riparian vegetation in surroundings of the minor watecourse Rosička through field research and subsequent inventory. In the theoretical part, I outlined the theme of watercourses and their modifications, revitalization and solutions. I also focused on vegetation accompaniment of the flows and their typology. I described the riparian and associated vegetation in detail, focused on their functions and establishment and on taking care of them. The final section of the thesis includes data of my field research. Here can be found the current condition of the species structure and the state of health of the riparian vegetation.
