Abstract
As result of our researches within Mamaia-Năvodari seacoast area, we have identified in the various coastal habitat types, 254 plant taxa and 38 plant communities. Among all identified species and subspecies, the percentage of littoral taxa is 66,41%. The difference (33,58%) represents ruderal, segetal and heat plants, consider by us invasive species. The high rate of these invasive plants in the studied area, higher than in other northern sea shore areas (Cape-Midia, Chituc sandbank) is a consequence of anthropic influences increase, especially because extension of economical activities (building works, touristic arrangement) until in proximity of dune habitats. The human activities which are generating offals, have favoured between Mamaia and Năvodari, the excessive development of weeds and ruderal plants communities, on the background of psamohalophilous primary vegetation decline.
