Abstract (eng)
This thesis is part of the Biodiversität auf Friedhöfen (BaF) Project. The main goal was the floristic recording and comparison of the α-diversity of the flora at three cemeteries, including the cemetery Rodaun, Kalksburg and Hetzendorf in Vienna, Austria. The botanical survey was carried out along the phenological period, starting at the end of December 2021, to the end of June 2022. On average, two inspections per month were conducted on each location. Transects, specially designed for those sites, were used to record the whole species pool, data were compared over the individual month and the whole period of data collecting. Before the data was collected, a habitat analysis of the locations had to be made. The common and different ecological conditions were incorporated into this analysis. Out of this, six different habitats were defined, which could be found on all the three cemeteries and were used for a better classification of the plant finds. Ordered to the diversity, differences were identified in case of the highest absolute species number over the whole period, found at the cemetery Rodaun with 272 species. Kalksburg had the highest score in diversity per space (α-diversity), which is around 10% higher than in Hetzendorf, and ~30% higher than in Rodaun. 14.45%-21.74% of the species richness of Vienna occour in the cementeries. Furthermore, there were differences in the vegetational periods of the total flora, their life forms, phenology, and in their colonised habitats as well.
