This site includes coastal dune ecosystems of Central Italy, both along Tyrrhenian and Adriatic coastline. The flora and the fauna of the site is highly specialized with a relevant ecological value. On the other side, the site includes one of the most threatened ecosystems at national and European level, mainly due to direct and indirect human pressures. These areas host many EU interest habitats and species and are included in the Nature 2000 Network. Major EU Habitats are: Habitat 1210 (Annual vegetation of drift lines), Habitat 2110 (Embryonic shifting dunes), Habitat 2120 (Shifting dunes along the shorelines with Ammophila arenaria), Habitat 2230 (Malcolmietalia dune grasslands), priority Habitat 2250* (Coastal dunes with Juniperus spp.), Habitat 2260 (Cisto-Lavanduletalia dune sclerophyllous scrubs) and priority Habitat 2270* (Wooded dunes with Pinuspinea and/or Pinus pinaster). The main topics of the ecological monitoring are: the temporal dynamics of plant diversity and abundance of coastal EU habitats, the periodical observation of nesting avifauna and Testudo hermanni, and the multi-temporal analysis of land cover types and its distribution, as well as of dune morphology and shoreline evolution.
