On this dataset we performed a multivariate analysis, resulting groups characterized by several points view: floristic, ecological, chorological, mean diagnostic species, use EIV. Moreover, distribution was better defined. According our results, six associations found be present Tuscany. Thereby, one new association three subassociations proposed. syntaxonomic arrangement above level discussed, Italian -rich communities. Finally, comparison Annex I habitat types (sensu Directive 92/43/EEC) out.
