Oltenia is located in the southwestern part of Romania, between the Danube, the Olt and the Southern Carpathians. The anthropogenic ecosystems in this part of the country are represented by those areas where human intervention is partial or total. These are confined from the plain to the Sub-Carpathian depressions. In Oltenia, there are to be found anthropogenic ecosystems comprising orchards, vineyards, protected crops (vegetables and flowers), as well as those of human settlements (rural and urban). Some spontaneous species found in these ecosystems are native plants that have shown an increased invasive potential in recent years. The analysis of data collected from the field shows an affinity of some species for certain anthropogenic ecosystems (ex. Calamagrostis epigeios (L.) Roth, Daucus carota L., Elymus repens (L.) Gould - for the orchards; Stellaria media (L.) Vill., Lamium purpureum L., Veronica hederifolia L., V. polita Fr., Senecio vernalis Waldst. et Kit. – for the viticultural ecosystems; Digitaria sanguinalis (L.) Scop., Cirsium arvense (L.) Scop., Sinapis arvensis L., Portulaca oleracea L. – for vegetable crop areas); Cardaria draba (L.) Desv., Capsella bursa pastoris (L.) Medik., Hordeum murinum L., Onopordum acanthium L. - for the human ecosystems. On the other hand, there are certain species found in almost all types of anthropogenic ecosystems: ex. Cynodon dactylon (L.) Pers., Convolvulus arvensis L.
