“…Indeed, it is known that neophytes mostly occur in strongly anthropogenic areas, whose habitats appear to be not only the most invaded, but also the most invasible (Pyšek et al 2002(Pyšek et al , 2005Deutschewitz et al 2003;Kühn et al 2003;Chytrý et al 2008). On the contrary, relatively low-or non-anthropized ecosystems, such as nutrient-poor environments or montane habitats, are least or not invaded (Ch-ytrý et al 2008;Angiolini et al 2019). For these reasons, heavily human-impacted environments (i.e.…”

“…This seems to some extent more important than alien species number, suggesting the hypothesis that the more an alien taxon becomes dominant in a vegetation type, the stronger the impact on native species diversity might be. This approach gave a pulse to research on alien plant species assemblages, and recently investigations on IAS have been addressed also at the community scale and benefitted from the currently available large databases of vegetation plots (see, e.g., Dengler et al 2011;Landucci et al 2012;Del Vecchio et al 2015;Chytrý et al 2016;Sperandii et al 2018;Bonari et al 2019).…”

“…Some authors started to qualify and quantify the role of alien species in different vegetation and habitat types, and to point out the functional role that alien species play in plant communities (Celesti-Grapow et al 2010;Pyšek and Chytrý 2014;. Moreover, habitat misclassification can be favoured by the presence of alien species (Sarmati et al 2019). However, to date only few studies focussed on alien-dominated plant communities and the role of aliens in natural assemblages.…”

This study provides a first step toward the knowledge of the alien-dominated and co-dominated plant communities present in Italy. The first ever checklist of the alien phytocoenoses described or reported in literature for the Italian territory has been compiled, produced by data-mining in national and local thematic literature. The resulting vegetation-type draft-list has been checked in the light of the most recent syntaxonomic documentation and updated with regards to syntaxonomy and nomenclature, with special reference to the frame proposed in the Italian Vegetation Prodrome. The list includes 27 vascular and one bryophyte vegetation classes, hosting 194 low rank alien-dominated syntaxa. The different vegetation types detected for each syntaxonomic class and macro-vegetation group, defined by physiognomical and ecological attributes, are discussed.

“…The valuable ecological diversity and the multiple ecosystem services associated to dune habitats have been progressively threatened by the expansion of anthropic activities and also by natural factors, making coastal dunes among the most threatened ecosystems at the global and local scale (Schlacher et al 2007;Defeo et al 2009;Prisco et al 2015Prisco et al , 2016aAcosta and Ercole 2015;Janssen et al 2016;Malavasi et al 2016;Marcenò et al 2018;Sarmati et al 2019;Carranza et al 2020). Although the Italian shoreline still hosts several of well-preserved stretches of sandy dunes, the 4th monitoring Report just completed has clearly highlighted the alarming bad or inadequate conservation status of most dune habitats in Italy.…”

Coastal dunes are among habitats with the worst conservation status on a global, European and national scale. Monitoring and reporting are of strategic importance to determine the effectiveness of the implementation of Habitats Directive and to preserve the unique biodiversity heritage of the Italian dunes. In this study we show main results of the 4th National Report with specific reference to the macro-habitat “Coastal Sand Dunes and Inland Dunes”, highlighting its updated current conservation status at the national and Biogeographical level. A comprehensive Working Group of territorial experts collected, updated, validated and integrated the data available for 11 Annex I Habitats, distributed in the Alpine, Continental and Mediterranean Biogeographical Regions. The conservation status was evaluated through the following criteria: geographic range, surface area, structure, functions, pressures, threats, conservation measures and prospects. Results highlighted the dramatically bad conservation status of Italian dune Habitats: the overall assessment reported 88% of habitats in bad conservation status and the remaining 12% is in inadequate conditions. Results showed a generalised threat and a worrying conservation status both on herbaceous and wooded communities, in particular in some relevant habitats, such as the shifting dunes. Main pressures and threats were linked to residential, commercial and industrial activities, as well as alien species. Although some of the changes in distribution and trends are probably deriving from more accurate and updated data, the alarming conservation status of Italian sand dunes requires a better knowledge of pressures and threats for further management actions and monitoring plans, inside and outside protected areas.

“…Worldwide, coastal dunes and other psammophytic habitats are recognized as highly vulnerable and dynamic ecosystems (Rannow & Neubert, 2014;Acosta & Ercole, 2015;Sarmati et al, 2019); in Ukraine and other countries they are systematically over-used. Inadequate land management contributes to the fact that these habitats are threatened with extinction, especially in the Mediterranean region (Sabatini et al, 2018).…”

Pioneer psammophytic vegetation is usually developed on wind-drift sandy substrates such as arenas, spits, beaches, river terraces, and this vegetation occupies significant areas in all three natural zones of Ukraine. The Koelerio-Corynephoretea canescentis class was represented by 13 associations, 3 alliances and 1 order; Festucetea vaginatae class by 22 associations, 2 alliances and 1 order; Helichryso-Crucianelletea maritimae by 10 associations, 4 alliances and 1 order. The results of cluster analysis and synoptic tables of the classes are presented. 9 alliances are briefly described. Leading factors of territorial and ecological differentiation are identified. It was found that the territorial distribution of plant communities is influenced by the character of ecotope mesorelief, soil composition and humus horizon thickness, as well as the degree of eolian processes development. The main factors of their ecological differentiation are soil acidity, salt regime and ombroregime. Based on the results of DCA-ordination of syntaxa within certain vegetation classes, it was found that their distribution is influenced by factors that correlate with the environment-specific conditions. It has emerged that an ecological differentiation of syntaxa within Festucetea vaginatae is determined by the integrated effect of gradients, and soil salinity is leading among them. Temperature regime and climate continentality are leading factors in the distribution of syntaxa within the Koelerio-Corynephoretea canescentis class. The gradients of ombroregime and soil humidity have a significant impact. The distribution of communities of the Helichryso-Crucianelletea maritimae class in the ecological space is determined mainly by factors of variability of damping, ombroregime and climate continentality. The author’s syntaxonomic concept assumes the independence of the studied classes: Koelerio-Corynephoretea canescentis, Helichryso-Crucianelletea maritimae and Festucetea vaginatae, considering that the leading factors of community differentiation of the Festucetea vaginatae and Koelerio-Corynephoretea canescentis classes are the origin (genesis) of sandy substrates, as well as soil acidity. Phytosociological analysis of a large number of relevés of coastal littoral vegetation also provides support for independence of the Helichryso-Crucianelletea maritimae and Ammophiletea classes different floristically and ecologically. A review of the psammophytic vegetation of Ukraine will determine the place of the selected syntaxonomic units in the pan-European system.
