ABSTRACT
The annual vegetation of the shoreline is typical for the habitat 1210 in accordance with Habitats Directive. In the coastal zone of Danube Delta Biosphere Reserve (DDBR), this type of vegetation is well represented by five plant communities which grow on slightly salty sands, fine or coarse, enriched with nitrogenous organic matter, sporadically flooded by sea waters during storms. The shoreline vegetation is generally well developed on the wide beaches (Sulina, Sf. Gheorghe, Chituc sandbank) between the midlittoral and the first strip of sand dunes but often reach on the eastern slope of the dunes where they interfere with the psammophilous plants belonging to the class Ammophiletea. On the narrow beaches (Sacalin-Zătoane, Periboina-Perișor) bordered in the west by lakes, ponds or marshes, the reeds often reach up to the sea proximity and limit the development of the typical seashore vegetation. Conservation status of the habitat 1210 is generally favorable in all coastal areas of DDBR, less on the beaches designated for recreational activities (Sulina, Sf. Gheorghe, Portița). Both the storms and strong winds and also the grazing, invasive species or touristic activities are the main pressures and vulnerabilities of the shoreline vegetation in the coastal area of DDBR.
