Passive restoration of vegetation on gravel/sand bars in the city: a case study in Prague, Czech Republic

Popis výsledku v původním jazyce

Riparian zones provide many ecosystem services and are a frequently found type of green area in urban ecosystems. These areas increase the aesthetic value of urban landscapes. The aim of this 17-year study was to assess the applicability of passive vegetation restoration of the gravel/sand bars that emerged after a devastating flood along the river in the city of Prague. The number of species and the sum of their coverages rapidly increased for the initial six years. After the twelfth year, the vegetation composition gradually began to stabilize. Species diversity increased for seven years after the beginning of the succession and then remained essentially unchanged. The diversity values were lower on finer substrates with higher proportions of dust and clay particles. The neophytes, i.e. species introduced after the year 1500, established with more successful on substrates with greater soil skeleton proportions. Finer substrates were preferred by graminoids, among them, the invasive Arrhenatherum elatius was the most abundant. The share of invasive species in the total vegetation cover initially fluctuated at approximately 40%, after eight years, it stabilized at approximately 10%. The proportion of naturalized alien species stabilized within the range of 20-30%. The results show that a new type of species-rich vegetation spontaneously emerged on gravel/sand bars. The vegetation consisted mainly of native and naturalized non-invasive alien species. However, attention needs to be given to potential alien plant invasions.
