A survey and a formalized phytosociological classifi cation of the marsh vegetation of the class Phragmito-Magno-Caricetea in central Italy is presented. Formal defi nitions of the majority of wetland associations recorded from the Italian territory were defi ned using the Cocktail method and applied to a large data set of vegetation plots extracted from the database VegItaly (hosted by the web database system “anArchive”). A total of 43 associations belonging to seven alliances and four orders were recognized. Detrended correspondence analysis (DCA), species indicator values and altitude were used to visualize ecological differences between the associations. Altitude, nutrient status and soil reaction were identifi ed as the main environmental gradients responsible for diversifi cation and distribution of the Phragmito-Magno-Caricetea communities in central Italy.

Abstract
A survey and a formalized phytosociological classifi cation of the marsh vegetation of the class Phragmito-Magno-Caricetea in central Italy is presented. Formal defi nitions of the majority of wetland associations recorded from the Italian territory were defi ned using the Cocktail method and applied to a large data set of vegetation plots extracted from the database VegItaly (hosted by the web database system “anArchive”). A total of 43 associations belonging to seven alliances and four orders were recognized. Detrended correspondence analysis (DCA), species indicator values and altitude were used to visualize ecological differences between the associations. Altitude, nutrient status and soil reaction were identifi ed as the main environmental gradients responsible for diversifi cation and distribution of the Phragmito-Magno-Caricetea communities in central Italy.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
