“…Even though worldwide vegetation zonation in foredunes has been demonstrated decades ago (Doing 1985) and extensively confirmed in recent years (Wilson and Sykes 1999, Dech and Maun 2005, Isermann 2005, Levin et al 2008, Lomba et al 2008, the actual factors driving that zonation are yet controversial due to covariance and interaction among environmental factors (Dech andMaun 2005, Forey et al 2008). Nonetheless, a close relation between vegetation and sediment transport/deposition in coastal dunes has been reported by a number of authors (Maun and Perumal 1999, Baas 2007, Meerkerk et al 2007, Levin et al 2008. This relationship can provide deeper insights into the dynamics of dune landscapes, which can then support a range of applications in management, monitoring and restoration (Levin et al 2006, Baas andNield 2007).…”

Understanding dune ecosystem responses to multi-scale environmental changes can provide the framework for reliable forecasts and cost-efficient protocols for detecting shifts in prevailing coastal dynamics. Based on the hypothesis that stress and disturbance interact as primary community controls in coastal dunes, we studied the fine-scale floristic assembly of foredune vegetation, in its relation to topography, along regional and local environmental gradients in the 200 km long coastline of northern Portugal, encompassing a major biogeographic transition in western Europe. Thirty topographic profiles perpendicular to the shoreline were recorded at ten sites along the regional climate gradient, and vegetation was sampled by recording the frequency of plant species along those profiles. Quantitative topographic attributes of vegetated dune profiles (e.g. length or height) exhibited wide variations relatable to differences in prevailing coastal dynamics. Metrics of taxonomic diversity (e.g. total species richness and its additive beta component) and of the functional composition of vegetation were highly correlated to attributes of dune topography. Under transgressive dynamics, vegetation profiles have fewer species, increased dominance, lower turnover rates, and lower total vegetation cover. These changes may drive a decrease in structural and functional diversity, with important consequences for resistance, resilience and other ecosystem properties. Moreover, differences in both vegetation assembly (in meta-stable dunes) and response to increased disturbance (in eroding dunes) between distinct biogeographic contexts highlight a possible decline in facilitation efficiency under extreme physical stress (i.e. under Mediterranean climate) and support the significance of functional approaches in the study of local ecosystem responses to disturbance along regional gradients. Our results strongly suggest that assessing fine-scale community assembly can provide insights on the relation between dune vegetation, environmental filters and ecosystem processes. A combination of cost-efficient indicators from dune topography and vegetation is thus suggested as a promising approach to survey, forecast and monitor changes in coastal dune ecosystems.

“…The latter occurred close to the coastal town of Schoorl near transect 3000 in 1997 (Meerkerk et al, (2007)). Local increases in naturalness have been reported around transects 2600-3600 and 5900-6250 since the 1990s by Arens, (1999) and Löffler and Veer, September, (1999).…”

“…This was done with the understanding that the areas involved would contain enough information for characterization of texture for that specific environment. A review of literature describing large foredune systems indicates that most have widths of the order of 100 m or longer (e.g., Hesp 2002;Walker et al 2006;Meerkerk et al 2007;Hilton et al 2009;Delgado-Fernandez et al 2011) so the expedient, although necessarily imperfect, is geomorphologically justified.…”

Coastal dunes are sensitive ecosystems because of their location at the juncture of terrestrial, marine, and atmospheric environments. This is especially the case for foredunes and the vegetation they support. Considerable attention is paid to the characteristics of foredunes and dune vegetation, but there has been no systematic study of patterns of bare sand on foredune surfaces-foredune textures-and the climate variables controlling those patterns. We used landscape metrics to quantify foredune textures for twenty-two coastal locations in the contiguous United States and cluster analysis to classify textures using those metrics. Four types of texture were identified: (1) active, where bare sand averages more than 80 percent of the dune surface and sand patches are close together; (2) composite, with about 50 percent bare sand area and sand patches that are close together and of minimal complexity; (3) aggregated, where bare sand is about 23 percent of the surface and the sand patches are moderately adjacent, of relatively low complexity, and relatively far apart; and (4) inactive, where the bare sand averages about 6 percent of the surface and the patches are complex in shape and widely spaced. These types are discernible using four climate variables. We used those variables to derive multiple regression models to predict key landscape metrics and use Intergovernmental Panel on Climate Change climate predictions to forecast changes in foredune textures through the twenty-first century. We find that vegetation cover should increase at 82 percent of our sites.
