An objective of this bachelor thesis is a clarification of the terms related to the soil covering swards for roof greenery in light of build-constructing, technology as well as from botanic perspective. Another task of this work is to explore the examples in practice, specifically in the locations of Prague and Dresden. The analysis focuses on the realisation and aftercare of two extensive plant cover on administrative buildings. The method of visual classification and method of reduced projective domination estimation was used. On the base of botanic photographs and through botanic and phytocenologic analysis, the particular kinds of plants were figured out. Simultaneously, cover, climatologic, meteorologic and local specific conditions of the building were identified. Photodocumentation of the vegetation is enclosed. In Dresden location, the results of plant cover is by visually evaluated 100 %, zero appearance of seeding weed and maintenance has been realised 4 – 6 times per year. Extensive roof greenery is based on Sedum plants community of the Crassulaceae section. In Prague location, the results of plant cover is vissuall evaluated 80 %, appearance of seeding weed into 5 % Poaceae and also mosses, maintenance has been realised 1 – 2 times per year. In this extensive roof greenery are dominant Sedum plants of the Crassulaceae section and Allium molly, Allium schoenoprassum of the Liliaceae section. In conclusion, it is relevant to point out that further roof amenity planting has been a contribution in light of constructive, urbanistic, psycho-social as well as economical and business aspect in a long-term. Even though the input investment for realisation of such roof-concept is high, we can expect a rise of this trend in Czech Republic despite the lack of legislative support.
