Scope: Phytosociological review of Ammophiletea class in the Mediterranean coasts. 8000 phytosociological relevés were collected from relevant bibliography during the years 2004-2013. The stored data refer to the dune vegetation of West Mediterranean, North Africa, Middle East and Black Sea.
Abstract: Phytosociological review of Ammophiletea class in the Mediterranean coasts, in the years 2004-2013, about 8000 phytosociological relevés were collected from relevant bibliography. The collected data refered to the dune vegetation of west Mediterranean (Italy, Croatia, France, Spain, Portugal, Algeria, Morocco), North-Eastern Africa (Southern Tunisia, Libya and Egypt), Asia Minor (Palestine, Lebanon, Syria, Southern Anatolia), Cyprus, Crete, North Aegean, Marmara Sea and Black Sea. All the vegetation relevés following the Braun-Blanquet`s scale (Braun-Blanquet, 1964) have been digitized into Microsoft Excel table sheets, then unified in a single TURBOVEG-data-base (Hennekens & Schaminée, 2001). Only the cover values (abundance-dominance) have been transcripted from the original relevés, eventual abundance index "r" had been replaced with "+". All plant names have been standardized following the most recent taxonomical revisions. The survey reports information on: syntaxonomy (up to the association-level), distribution range, distribution density of all relevés, approx. longitude and latitude (all relevés had been georeferenciated according to the original localities provided by the authors). In agreement with Schaminée & al. (2009), it is hoped that the data-base at issue will be useful in studies related to macroecological hypotheses and for nature conservation surveying or monitoring.
