Our main objectives were to investigate: i) the main soil factors driving species composition in a Mediterranean coastal dune environment; ii) the ecological requirements of focal plant species with respect to single soil factors; iii) whether the focal species of a given macrohabitat (including EU habitats) have similar edaphic needs. We identified 108 plots with three macrohabitats as strata (embryo dunes; mobile dunes; fixed dunes) by random stratified sampling design along the Tyrrhenian coast of central Italy in areas with a high degree of biodiversity and naturalness. Vegetation and soil data were collected in the plots. Canonical Correspondence Analysis (CCA) confirmed that soil had a main role in driving focal dune species composition as found in other Mediterranean areas and indicated that three factors (field capacity, pH and CaCO3) sufficiently explain patterns of plant species. An inverse relation between field capacity, which proves to be the most decisive feature for differences in species ecological requirements between macrohabitats, and pH was observed. Generalized Additive Models (GAMs) showed that: i) the focal species of fixed dunes have a higher probability of occurrence and response curves that overlap at high field capacity and TOC values and at low pH, showing an opposite trend with respect to the species of embryonic and mixed dunes; ii) species of mixed dunes have a probability of occurrence linked to different values of CaCO3, with Ammophila arenaria showing its optimum at high CaCO3 values. Thus our results sustain the hypothesis that dune focal species, diagnostic and characteristic of coastal dune marcohabitats, have different ecological responses with respect to soil factors. Moreover, species within the same habitat can have different ecological responses due to species competition. Data about edaphic requirements of sand dune species and modelling of their ecological responses suggests that focal dune species can be bio-indicators of soil conditions and provide useful indications for conservation, monitoring and restoration of Mediterranean coastal habitats.

In this study, we analysed a debated habitat influenced by past human planting activities. We compared the Pinus halepensis and the P. pinea forests, belonging to the priority EU habitat 2270*, by means of ecological features provided by the Ellenberg indicator values and diagnostic species selected from “Vegetation of Europe” classes and the “Italian Interpretation Manual of the Dir. 92/43/EEC”. We used 159 vegetation plots in the Italian Peninsula, covering a wide range of this habitat in Italy. We found consistent ecological dissimilarities between Pinus halepensis and P. pinea forests and different diagnostic species. Moreover, P. halepensis forests hosted more diagnostic species of foredune habitats. Finally, we suggest that diagnostic species are a good indicator for studying EU habitat types resemblance, and we highlight the importance of the EU habitat 2270* in Italy, proposing two different subtypes.
