Abstrakt: The two species of Solidago, S. canadensis and S. gigantea, which were introduced in our country, as well as other parts of Europe, as ornamental plants, have become invasive in natural areas and, more recently, in crops. Several physical, biochemical, or biological characteristics support its ability to intrude into natural environments and crops. The vigorous monopodial growth of the stem until the inflorescence is induced enables species to attain a height of 2 meters, supported by extensive sclerenchyma rows found within the stem's internal structure. Using our observations and available S. canadensis occurrence data from the literature, we created an updated chorology map illustrating the species distribution in Romania. Subsequently, we used the R software, with the SSDM package, to generate the potential distribution map of S. canadensis in Romania based on these data. In creating the potential distribution map of S. canadensis, we considered various environmental variables corresponding to the species' ecological preferences, such as climatic, pedological, anthropogenic factors, and water regimes. The model performed well, effectively highlighting the environmental factors influencing the species' dispersion in Romania and the areas potentially affected by the spread of S. canadensis.
