“…Coastal dune vegetation has been often described as azonal (Acosta et al, 2003a;Buffa et al, 2007); this is mostly true for communities of beaches and mobile dunes which actually have been proved to have a wide geographical range (Biondi, 1999;Carranza et al, 2008). On the contrary, foredune systems, and particularly the edapho-xerophilous series, are delineated by floristic and coenological features which are more related to local conditions such as climate, morphology, lithology and history.…”

“…From higher to lower level, Blasi's framework includes : Although successfully applied to different ecosystems (Acosta et al, 2003a;Blasi et al, 2004;Stanisci et al, 2005), the method appears less workable in sandy coastal landscape, where the identification of single land elements is quite impossible at the scale proposed. For this reason, according to the proposal of Carranza et al (2008), in this study LU have been described through coastal dune geosigmeta which can be defined as a mosaic of adjoining vegetation series within a geomorphologic, biogeographical and bioclimatic unit (Biondi 1994;Blasi et al, 2005).…”

“…However, all over the world and, particularly in the Mediterranean, coastal ecosystems are considered to be highly endangered ( Van der Meulen and Udo de Haes 1996;Anthony 1997;Cori 1999;Kutiel et al 2000). Although many studies have focused on the analysis of plant communities and on threats faced by Mediterranean coastal dune populations, including coastal erosion and anthropogenic pressure (Pignatti 1993;Géhu and Biondi 1994;Acosta et al 2003;Valpreda and Simeoni 2003;Ercole et al 2007), little is known regarding patterns of spatial variability in species diversity (Isermann 2005). Given the sensitivity of coastal dune environments to human pressure and disturbance, it is essential to understand baseline diversity patterns of the community mosaic, especially in areas that still retain relatively well-preserved habitats (Grunewald and Schubert 2007).…”

Are there habitats that contribute best to plant species diversity in coastal dunes?

The following paper describes patterns of diversity across major habitat types in a relatively well\ud preserved coastal dune system in central Italy. The research addresses the following questions: (a) whether different\ud habitats defined on the base of a land cover map support similar levels of biodiversity in terms of vascular flora\ud richness and number of rare and endangered species, and (b) how each habitat contributes to the total species\ud diversity of the coastal environment. A random stratified sampling approach based on a detailed land cover map was\ud applied to construct rarefaction curves for each habitat type and to estimate total species richness. In addition, the\ud number of exclusive, rare and endangered species was calculated for each habitat type. Results highlight the\ud importance of the coastal dune zonation (embryo-dune, main dune, transition and stabilized dune) in species\ud conservation because they harbour progressively higher species richness. However, differences among these habitats\ud were not significant, so no particular species rich "hotspots" could be evidenced. On the contrary, rarefaction curves\ud show that the upper beach (strand) habitat sustains significantly smaller number of species, but surprisingly, it shows\ud the highest rarity values and highest proportion of endangered species. Therefore, for the establishment of successful\ud biodiversity conservation programs in these coastal environments, it is imperative not only to conserve biologically\ud rich hotspots but also to include species poor habitats containing endangered or unique elements. Thus, the complete\ud coastal vegetation mosaic including all coastal habitats is important to adequately characterize the plant species\ud diversity of coastal dune ecosystems

“…Ricotta et al (2000Ricotta et al ( , 2002 suggested using PNV distribution as a reference framework for landscape structure and function assessment. Following this, Acosta et al (2003) applied the PNV concept for the assessment of the state of conservation of coastal dune ecosystems in central Italy.…”

Many recent developments in coastal science have gone against the demands of European Union legislation. Coastal dune systems which cover small areas of the earth can host a high level of biodiversity. However, human pressure on coastal zones around the world has increased dramatically in the last 50 years. In addition to direct habitat loss, the rapid extinction of many species that are unique to these systems can be attributed to landscape deterioration through the lack of appropriate management. In this paper, we propose to use of an ecosystem classification technique that integrates potential natural vegetation distribution as a reference framework for coastal dune EU Habitats (92/43) distribution analysis and assessment. As an example, the present study analyses the EU Habitats distribution within a hierarchical ecosystem classification of the coastal dune systems of central Italy. In total, 24 land elements belonging to 8 land units, 5 land facets, 2 land systems and 2 land regions were identified for the coastal dunes of central Italy, based on diagnostic land attributes. In central Italy, coastal dune environments including all the beach area, mobile dunes and all the fixed-dune land elements contain or could potentially hold at least one EU habitat of interest. Almost all dune slack transitions present the potentiality for the spontaneous development of EU woodlands of interest. The precise information concerning these ecosystems distribution and ecological relationships that this method produces, makes it very effective in Natura 2000 European network assessment. This hierarchical ecosystem classification method facilitates the identification of areas to be surveyed and eventually bound, under the implementation of EU Habitat directive (92/43) including areas with highly disturbed coastal dune ecosystems.
