The evaluation of woody plantings carried out in revitalization small streams
KELLEROVÁ, Petra
The aim of this thesis is to evaluate the success of woody plantings carried out in order to revitalize small streams. For selected restorations was assessed dendrological composition, establishment, health and care after planting. The most common species planted in the revitalization of small streams is the alder (Alnus glutinosa), a pioneer tree species reinforcing shores, to which it was coupled with flowing water home. Sometimes forming groups with gray alder (Alnus incana) but that does not fit stagnant water and silver birch (Betula pendula). Also mountain elm (Ulmus glabra) and willow species (Salix sp.) are widely planted along streams. Locally, there were planted common ash (Fraxinus excelsior) but mostly in very poor condition, and oak (Quercus robur), sporadically rowan (Sorbus aucuparia), dogwood (Swida sanquinea) and Norway maple (Acer platanoides). A statistical evaluation shows that the biggest influence on species composition and state of health of trees has the revitalization age. Also important is the care of the vegetation in later years after planting.

Proposal of bank vegetation management at the selected streams.
ŠTĚPÁN, Vladimír
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.
