Threatened plant species of coastal dune habitats in Central Italy. Coastal dune habitats and the associated backdune marshes represent fragile environments, which therefore host many seriously threatened plant species. In this paper we present the results of a floristic census, which considered dune plant species of three regions in central Italy, focusing in particular on threatened species and on their conservation status. Numerous dune species recorded are typical of coastal dune habitats that are listed in “Habitats” Directive and many are included in regional Red Lists. Abruzzo is the region with the highest number of threatened species, followed by Molise and Lazio. The threat status of many typical coastal dune species often differs among examined regions. Floristic data obtained through this census, coupled with distribution maps of the single species, represent a useful tool for more objective compiling of red lists, for the individuation of new dune species that deserve protection and for a future reconsideration of species to be considered threatened on the basis of the new 3.1 version of the IUCN categories and criteria.
