Understanding and predicting changes in community composition, plant distributions and ecosystem functions in the era of climate change has become a central issue of invasive plant ecology. There is a large volume of published studies suggesting that traits related to reproduction, such as timing of flowering, high seed production, good seed viability and long-distance dispersal ability can promote species invasion potential. This paper presents results of the research conducted on several locations in Belgrade where Aster lanceolatus Willd. spread rapidly, forming dense patches over large areas. Late flowering period, high seed production, long-distance dispersal ability and rapid vegetative spread were noticed. This results suggest that Aster lanceolatus Willd. have high reproductive potential. This characteristic will be even more significant with the climate change driving extreme weather conditions, which are likely to support the spread of this invasive perennial.
