After the Pannonian Sea has dried up, the Pannonian Basin has become a major depression in Central Europe. The continental climate and intensive groundwater evaporation from the upper layers of the soil caused the accumulation of salts and the formation of Solonchak and Solonetz soil. A mosaic of very specific halophytic vegetation has developed on these soils. Pioneer, species-poor vegetation of annual succulents of the Therosalicornietea class occupy the exposed bottoms of salt marshes and inland salt lakes. Very similar vegetation of the class Crypsietea aculeatae is developed in periodically flooded bare shores and bottoms of salt lakes, dead oxbows, ponds, and terrain depressions. Typical vegetation of inland salt steppes is included in the class Festuco-Puccinellietea, while
