Perennial adventitious species Asclepias syriaca L. which originates from Northern America is spread across Serbia, and especially Vojvodina, along the banks of waterways and borders of floodplain forests. Based on floristic and phytocenological studies in Bačka, the presence of ass. Asclepiadetum syriacae Lániková in Chytrý 2009 stands, in which A. syriaca is present with the highest degree of presence (V) and with substantial covering value (2850), can be confirmed. The study shows ecological analysis of stands of mentioned association for basic environmental factors (moisture – F, reaction – R, nutrients – N, humus – H, aeration – D, light – L, temperature – T, and continentality – K) based on floristic composition of stands and their ecological indices, considering population and every species coverage in a stand. Given that a combined scale for population and coverage of species in stands, along numerical, has descriptive marks, modification of evaluated values according to Westhoff & van der Maarel scale which is completely numerical was conducted, which enabled data processing. The obtained results of the ecological analysis point to favorable ecological conditions for development of stands of this association, which can help predict the possible directions of spread of this invasive species.
