- Abstract:
- In times of climate change, green spaces play an increasingly important role, especially in urban areas. In the course of the GrünPlusSchule research project, an extensive green roof with several experimental areas equipped with different measuring techniques and subsequently ecologically evaluated was created at GRG7 in Vienna (KORJENIC A 2018). The main focus was the investigation of the establishment of Pannonian vegetation on extensive green roofs and the effects of structures on them. The following questions were formulated: • How is the establishment of Pannonian vegetation on extensive green roofs possible? • Which factors affect the development of Pannonian vegetation? -Is there an added value of the structures? -What are the advantages and disadvantages? • How can suitable maintenance measures for such extensive green roofs look like? In order to answer the questions dealt with in this Master's thesis, the method will first be guided through the site description and the experimental background, as well as the roof structure. In order to evaluate the establishment of Pannonian vegetation on extensive green roofs, the soil moisture and temperature of the substrate were measured on six test plots of the same size and the frequency and dominance of the vegetation was determined and then compared. The results showed that a establishment of Pannonian vegetation on extensive green roofs is possible and reasonable. Of the 30 species applied, 12 were able to develop and formed a closed vegetation cover on some experimental sites. The structures also have a positive effect on the vegetation by creating a milder microclimate where the flora can retreat during dry periods. The establishment of Pannonian vegetation is therefore so relevant as it is very resistant to drought, but at the same time provides ecological added value.
