63. Validation of names of some syntaxa of the Crimean vegetation

Aims Vegetation classification consistent with the Braun‐Blanquet approach is widely used in Europe for applied vegetation science, conservation planning and land management. During the long history of syntaxonomy, many concepts and names of vegetation units have been proposed, but there has been no single classification system integrating these units. Here we (1) present a comprehensive, hierarchical, syntaxonomic system of alliances, orders and classes of Braun‐Blanquet syntaxonomy for vascular plant, bryophyte and lichen, and algal communities of Europe; (2) briefly characterize in ecological and geographic terms accepted syntaxonomic concepts; (3) link available synonyms to these accepted concepts; and (4) provide a list of diagnostic species for all classes. Location European mainland, Greenland, Arctic archipelagos (including Iceland, Svalbard, Novaya Zemlya), Canary Islands, Madeira, Azores, Caucasus, Cyprus. Methods We evaluated approximately 10 000 bibliographic sources to create a comprehensive list of previously proposed syntaxonomic units. These units were evaluated by experts for their floristic and ecological distinctness, clarity of geographic distribution and compliance with the nomenclature code. Accepted units were compiled into three systems of classes, orders and alliances (EuroVegChecklist, EVC) for communities dominated by vascular plants (EVC1), bryophytes and lichens (EVC2) and algae (EVC3). Results EVC1 includes 109 classes, 300 orders and 1108 alliances; EVC2 includes 27 classes, 53 orders and 137 alliances, and EVC3 includes 13 classes, 24 orders and 53 alliances. In total 13 448 taxa were assigned as indicator species to classes of EVC1, 2087 to classes of EVC2 and 368 to classes of EVC3. Accepted syntaxonomic concepts are summarized in a series of appendices, and detailed information on each is accessible through the software tool EuroVegBrowser. Conclusions This paper features the first comprehensive and critical account of European syntaxa and synthesizes more than 100 yr of classification effort by European phytosociologists. It aims to document and stabilize the concepts and nomenclature of syntaxa for practical uses, such as calibration of habitat classification used by the European Union, standardization of terminology for environmental assessment, management and conservation of nature areas, landscape planning and education. The presented classification systems provide a baseline for future development and revision of European syntaxonomy.

“…According to Arts. 2b & 5 of the International Code of Phytosociological Nomenclature (Theurillat et al 2020), we propose the holotypus of the new alliance as the Bromopsido tauricae-Asphodelinetum tauricae association type that was formerly considered (Didukh & Mucina 2014) within the alliance Veronico multifidae-Stipion ponticae.…”

“…The alliance Androsaco tauricae-Caricion humilis was considered by Didukh (1981) to be within the order Festucetalia valesiacae, but it was later transferred to Bromopsidetalia cappadocicae Didukh in Saitov et Mirkin 1991, which was not validly described (Korzhenevskii 1990, Saitov & Mirkin 1991, and was later included in Stipo pulcherrimae-Festucetalia pallentis (Didukh & Mucina 2014, Mucina et al 2016. These are communities of petrophytic meadow steppes of table-like peaks of the Crimean Mountains (called "Yaila"), which are distributed at an altitude of 900-1450 m a.s.l.…”

Nine hundred and eight-nine relevés from calcareous petrophytic steppes in Ukraine and its adjacent territories were assessed with the help of expert systems to determine the syntaxonomic affiliation of the plant communities at class and order levels. At least 488 relevés belonging to the class Festuco-Brometea were analyzed using the TWINSPAN algorithm, and 8 distinctive clusters were obtained, recognized as alliances of the order Stipo pulcherrimae-Festucetalia pallentis. A new alliance, Bromopsido cappadocicae-Asphodelinion tauricae, was ascribed to the Crimean Mountains and the presence of two alliances, Diantho lumnitzeri-Seslerion albicantis and Genisto tetragonae-Seselion peucedanifoliae, was confirmed as new for this vegetation in Ukraine. Unlike in the Pannonian Basin, Bromo pannonici-Festucion csikhegyensis alliance communities mentioned in the literature do not occur in Ukraine. Centaureo carbonatae-Koelerion talievii has been provisionally transferred from Festucetalia valesiacae to the order Stipo pulcherrimae-Festucetalia pallentis. Furthermore, we distinguished alliances by their geographic locations and their climatic (thermoregime, cryoregime, light in communities) and edaphic (carbonate content, salinity, and acidity) features.

The role, place in the spatial structure and functioning of shrub ecosystems as well as causes of underestimation of their importance in the development of dominantcoenotical classification of vegetation are considered. It is noted that the syntaxonomic rank of the shrub ecosystems is raised in the process of development of ecofloristic classification. The current version of EuroVegCheklist includes 10 classes, and some orders and alliances are considered in other classes. In the EUNIS classification of habitats, the shrubs are assigned to a specific type (F), which includes 11 positions of the second hierarchical level and 41 -of the third one, but some shrub habitats are assigned to other types. Based on a critical analysis of the European vegetation and habitats classification, the changes to the classification scheme of the Ukrainian biotopes are proposed. The new version of this scheme includes 7 positions of the second level. This scheme is designed to 45 hierarchical levels and is a basis for assessing biodiversity of the Ukrainian biotopes and their identification in relation to the European classifications.
