The work was mainly based on the study of literature and herbarium specimens. In some cases SEM observation of spores has proved useful. Data collected from herbarium specimens and other verified sources were loaded into a database, from which a distribution map was prepared for each taxon. Several preliminary papers have been published, and for each family a taxonomic conspectus, with type designations, maps and an identification key, has been prepared. The treatment of these three families for the "Flora Critica d'Italia" (in Italian) is about to be published or (Isoetaceae) has already been published.

The plant-communities are represented by halophilous communities (Juncetea maritimi), riverine hygrophilous communities (Phragmito-Magnocaricetea), psammophilous coenoses (Ammophiletea, Cakiletea maritimae), chasmophytic coenoses (Asplenietea trichomanis), woody and nanophanerophytic coenoses (Quercetea ilicis), and steppic prairies (Lygeo-Stipetea). The floristic analysis testifies the importance of this Reserve, in which 2 taxa exclusive to this area (Centaurea panormitana subsp. seguenzae, Festuca humifusa), 9 regional endemics and other 14 at risk according to the Regional Red Lists.
