ABSTRACT
In the coastal area of the Danube Delta Biosphere Reserve, the halophytic vegetation of the classes Puccinellio-Salicornietea Țopa 1939 and Juncetea maritimi Br.-Bl. 1931 is well developed on the salty soils, in the moist or marshy areas of the beaches, on the marine sandbanks, and around the saltwater lakes and ponds. This type of vegetation belongs to certain habitat types with conservation significance for European Community, according to Annex I of the Directive 92/43/EEC. Salinization of the substrate is sulfate-chloride type, due to the strongly mineralized groundwater and to the hyper-saline lakes from the coastal area. Details regarding the floristic structure of the most important halophilic plant communities of the alliance Juncion maritimi Br.-Bl. 1931 and the soil particularities within their specific habitat are highlighted in the paper. Grazing is the main threat to the halophytic vegetation of the alliance Juncion maritimi along the coastal area of the Danube Delta Biosphere Reserve.
