Comparison of the differences in the composition of ruderal flora between conventional tram tracks and managed green tram tracks in the urban ecosystem of the city of Bratislava
Green infrastructure (GI) brings many benefits to urban ecosystems (e.g. better air and water quality) and it presents ahelpful tool in the effort to reduce the consequences of climate change. Green tram tracks can be considered to be a part of GI. The presented study is focused on the comparison of the frequency of ruderal plant species, as well as species composition when comparing conventional tram tracks with green tram tracks (with planted succulents and ornamental plants) in Bratislava, Slovakia, Central Europe. This comparison also provides an insight into the changes of the flora of tram tracks over time, as we compare the results of the older research (from the years 2014–2019) with recent research on green tram tracks, which were built in Bratislava in 2020. The data were analysed by cluster analysis, Sign test and Wilcoxon two-sample test in the R 3.5.1. The results revealed significant differences in the composition of flora between conventional tram tracks and green tram tracks. In particular, the total number of species has decreased over time, as green tram tracks host fewer spontaneously growing taxa than conventional ones. The frequency of occurrence of archaeophytes and neophytes has decreased on the strict rail yard (covered by planted succulents) while on the tracksides (covered by non-succulent ornamental plants) it has increased. Green tram tracks deliver positive features to ecosystems, but may also have negative aspects because they present apool of alien, potentially invasive plants.
