Geobotanical research, realized to support the elaboration of the Park Naturalistic Plan, is presented. Synphytosociological and geosynphytosociological studies have highlighted the dynamic models of botanical landscape and the soil/plant relationship. The integrated study of the landscape allowed to carry out the Vegetation Map and the Landscape Units Map in which it is possible to identify 6 landscape ecological units, deriving from a whole of vegetation series. The integration of this map with the Soils Map will allow to define some multidimensional landscape units to which correspond sets of ecosystems which are related each other through some mechanism. The knowledge of these mechanism could steer us into a most rational management of the territory.
