AQUATIC AND MARSHY VEGETATION IN THE CENTER OF THE LOWER PLAIN OF SOMES RIVER: GENERAL CHARACTERISATION

Aiming to a larger study of vegetation of the lower Some Plain (Romania), this short paper summarises the outcome of the floristic inventories performed in aquatic and marshy vegetation, which was dominant in the area until about three centuries ago when the extended wetland drainage has started. By using the phytosociological method, 20 plant associations assigned to four vegetation classes were distinguished. Without presenting phytosociological tables at this first stage, the syntaxonomical framework, distribution and species composition of the revealed plant communities are briefly discussed by reference to the process of wetland drying and successional change as well as to newly formed anthropogenic lakes. The conservative value of some plant community types is emphasized by mentioning the presence of several endangered species that are included in the European-level Habitats Directive and various regional or national red lists/books.
