The anthropic activity determines the expansion or reduction of the habitats of plant species. The commercial exchanges of seeds and the acclimatization ability of the segetal species to various pedoclimatic conditions, may determine the exceeding of adventive species level and move towards species with a wider habitat, often cosmopolite species. Under this aspect, it is chronologically and ecologically analyzed the species Ambrosia artemisiifolia which can become problematic in the Western Plains of Romania in the years to come, considering its tendency to develop from a ruderal into a segetal species.
