The muddy journey continues… Further developments of the project WetVegEurope

The project WetVegEurope began in 2013, intending to review the existing literature and produce a consistent and unequivocal phytosociological classification of the European marsh and aquatic vegetation at the association level. In 2020, a paper was published with a hierarchical formalized classification of the European marsh vegetation into 92 associations, 11 alliances and 6 orders of the class Phragmito-Magnocaricetea. It was mainly focused on the methodological and conceptual background of the classification. In 2021, the 4th edition of the International Code of Phytosociological Nomenclature was published. Therefore, an update of the syntaxonomic nomenclature of our classification units was needed. Along with this update, we produced an extensive monograph of Phragmito-Magnocaricetea in Europe with a revised syntaxonomic nomenclature (according to the new Code) and descriptions and distribution maps of the associations. The work is still in progress, involving several experts who are writing descriptions of individual units. The distribution maps were created using the same data as used for the classification, literature information and knowledge of the experts involved in the project. The nomenclature part has been revised by some authors with the help of the members of the Steering Committee of the IAVS Group for Phytosociological Nomenclature (GPN).
