Invasive species Aster lanceolatus grows on moist habitats on the whole territory of Serbia. In Belgrade, this species is recorded with a higher degree of presence at a number of localities. With the aim to investigate the community in which this species is dominant, the wide area of Serbia was researched, and 8 localities on the territory of Belgrade were chosen for the analysis of the community. Floristic structure of the community was determined by the standard Braun-Blanquet method (1964), phytogeographical analysis was performed according to Gajic (1980, 1984), and determination of life forms according to Raunkier (Ellenberg, Mueller-Dombois, 1967). pH soil analysis and electric conductivity (EC) were performed at all investigated localities. It was established that the community dominates the moist habitats of Belgrade. It is composed of 104 species and among them Aster lanceolatus Willd., Cichorium intybus L., Agropyrum repens (L.) Beauv., Calystegia sepium (L.) R. Br., Cirsium arvense (L.) Scop., Symphytum officinale L. and Rumex obtusifolius L. are the most frequent. In relation to life forms, the community has hemicriptophytes character, and in relation to phytogeography Euroasian and Middle Europaean floral elements are dominant, with a high presence of cosmopolitan and adventive floral elements. On the locialities Veliko Ratno ostrvo (island) and Makis, EC values point to the fact that the amount of nutrient in the soil is higher than at other localities. Invazivna vrsta Aster lanceolatus raste na vlaznim stanistima na celoj teritoriji Srbije. U Beogradu je visok stepen prisustva ove vrste zabelezen na nekoliko lokaliteta. Sa ciljem da se istrazi zajednica u kojoj dominira ova vrsta, istrazena je sira teritorija Srbije, a na teritoriji Beograda je za analizu ove zajednice izdvojeno 8 lokaliteta. Floristicka struktura zajednice je utvrdjena metodom Braun-Blanquet (1964), fitogeografska analiza je uradjena metodom prema Gajicu (1980, 1984), a utvrdjivanje bioloskih oblika prema Raunkier-u (Ellenberg, Mueller-Dombois, 1967). Na svim istrazivanim lokalitetima je uradjena analiza pH vrednosti zemljista kao i elektricne provodljivosti (EC). Utvrdjeno je da ova zajednica dominira vlaznim stanistima Beograda. Sastoji se od 104 vrste medju kojima su najucestalije Aster lanceolatus Willd., Cichorium intybus L., Agropyrum repens (L.) Beauv., Calystegia sepium (L.) R. Br., Cirsium arvense (L.) Scop., Symphytum officinale L. i Rumex obtusifolius L . Sto se tice bioloskih oblika, zajednicu odlikuje hemikriptofitski karakter, a sa fitogeografskog aspekta dominantni su evroazijski i srednjeevropski floralni elementi uz izrazeno prisustvo kosmopolitskih i adventivnih floralnih elemenata. Na lokalitetima Veliko Ratno ostrvo i Makis vrednosti EC ukazuju na cinjenicu da je kolicina hranljivih materija veca nego na drugim lokalitetima.
