Relevant habitats neglected by the Directive 92/43 EEC: the contribution of Vegetation Science for their reappraisal in Sicily

Field investigation carried out by the Sicilian botanists in last 20 years enabled them to identify eight habitat types of high biogeographic and conservation interest, neglected Directive 92/43, which deserve ad hoc measures. For each these habitats, a syntaxonomic interpretation corresponding plant communities, their main ecological, physiognomic syndynamic traits list diagnostic species are provided. Their classification into macrotypes listed Annex I 92/43 respective correspondence EUNIS proposed. The habitats here described integrate those already proposed Italian Botanical Society, with hope an adequate recognition at national supranational level.
