Sažetak
Syntaxonomy of dry grasslands and scrub in Southern Europe is quite complex and still has numerous issues to unravel. There are many blurry boundaries between the vegetation units, especially in submediterranean areas, which is further complicated by the regional focus of most studies. We aim to delimit geographically, ecologically and floristically the calcareous perennial dry grasslands and scrub of Southern Europe on the level of vegetation classes. This delimitation will help clarify the position of some syntaxonomical units and allow conducting classification studies at lower syntaxonomic levels. Moreover, as many of these vegetation types are vulnerable and endangered, our results might be a basis of proper conservation and management measures. The geographical scope of the project is Southern Europe including Portugal, Spain, France, Italy, Slovenia, Croatia, Bosnia and Herzegovina, Serbia, Montenegro, Kosovo, North Macedonia, Albania, Greece, Bulgaria and Turkey. We used the vegetation plots of calcareous perennial dry grasslands and scrub from the EVA database based on the vegetation class assignment (Astragalo-Brometea, Carici-Genistetea lobelii, Daphno-Festucetea, Elyno-Seslerietea, Festuco hystricis-Ononidetea striatae, Festuco-Brometea, Lygeo sparti-Stipetea tenacissimae, Ononido-Rosmarinetea, Poetea bulbosae, Trifolio anatolici-Polygonetea arenastri) and corresponding units of the EUNIS habitat classification. Altogether we collected 69, 758 relevés from 15 countries. We used only relevés with plot area ranging from 9 m2 to 100 m2 and applied a geographically stratified heterogeneity-constrained resampling. After taxonomic homogenization, we used different classification techniques (such as TWINSPAN and fuzzy C-means) and based on the results, prepared clear floristic definitions with diagnostic species of phytosociological classes and developed an electronic expert system.
