Braun-Blanquet meets EcoVeg: a formation and division level classification of European phytosociological units

Aims : To link the Braun-Blanquet units of EuroVegChecklist (EVC) with upper levels International Vegetation Classification (IVC), and to propose a division level classification for Europe. Study area Methods We established tabular linkage between EVC classes IVC formations identified mismatches these two levels. then proposed organize classes. Results organized into 21 30 divisions. flagged that did not fit comfortably within an existing formation, either because its content corresponded more than one formation or it any description. In few cases, we split they seemed too heterogenous be assigned single formation. Conclusions The approach adds set physiognomic ecological criteria effectively organizes classes, which are already being increasingly informed by physiognomy. Therefore, concepts relatively natural extensions embedded in However, placement can difficult when sampling vegetation is at finer grain usual respective (tall-scrub, annual pioneer communities). Some seem system. Delimitation has often been matter debate many decades, perspective might help solve intricate issues. other phytosociological better solved emending current concepts.
