HALOPHILE VEGETATION OF THE SLOVENIAN SEACOAST: THERO-SALICORNIETEA AND SPARTINETEA MARITIMAE

Halophile vegetation of the Slovenian sedimentary seacoast have been sampled with the standard Braun- Blanquet procedure. All the 140 collected relevés have been classified using the SYN-TAX 2000 software. The resulting dendrogram separated 5 well-defined clusters, characterized by different dominant species. Two well separated clusters have been further elaborated in this study. The floristically-poor association Suaedo maritimae-Salicornietum patulae Brullo et Funari ex Géhu et Géhu Franck 1984 tend to form monodominate stands with Salicornia europaea s.l. on mudflat hypersaline stands. The association Suaedo maritimae-Bassietum hirsutae Br.-Bl. 1928, with high abundance of Suaeda maritima occupy smaller surfaces on drier stands. Both were classified within halophile annual swards of the class Thero-Salicornietea. Spartina maritima-dominated perennial halophyte saltmarshes are represented with association Limonio-Spartinetum maritimae (Pignatti 1966) Beeft. et Géhu 1973 (class Spartinetea maritimae), which colonizes muddy islets, perturbed by high tide and sea turbulence and supports brackish water, which should be rich in nutrients.
