The Halophytic Vegetation in South-East Bulgaria and Along the Black Sea Coast

The Halophytic Vegetation in South-East Bulgaria and Along the Black Sea Coast The paper presents results of a syntaxonomic analysis of the herbaceous phytocoenoses on the salt steppes, meadows and marshes in Southeastern Bulgaria, and along the Southern Black Sea Coast. The halophytic vegetation is distributed mostly in the Tundzha Lowland and the large salt lakes along the Black Sea Coast, where the saline soils occupy large territories. Most syntaxa identified in the paper are well-known and wide-spread in Central and Eastern Europe (Salicornietum prostratae, Suaedetum maritimae, Juncetum maritimaeetc.), but there are also some specific vegetation types, which are presented by endemic associations asPetrosimonio brachiatae-Puccinellietum convolutae, Bupleuro tenuissimae-Camphorosmetum monspeliacae.The most widespread one isDiantho pallidiflori-Puccinellietum convolutae.It demonstrates a big variation in the appearance and the dominant structure of the described phytocoenoses. The comparision of the Bulgarian halophytic vegetation with other places in Europe shows its similarities with these vegetation types distributed in the Eastern Mediterranean and Central and Eastern Europe.
