“…Since the Sedo-Ctenopsion communities grow among the shrubs of the Gypsophiletalia order, both habitats should arguably be granted priority status. By contrast, the Omphalodion commutatae communities grow primarily on the shrublands of the Convolvuletalia bossieri order (Mota, 1990;Gómez Mercado et al, 2006), but surprisingly this latter has not been considered as a priority habitat.…”

Abstract.-The shrublands of the Convolvuletalia boissieri order have been known since 1953, when Quézel published the first association in the dolomites of Sierra Nevada (south of Spain). Despite their enormous floristic and ecological originality, the Habitats Directive 92/43/EEC does not mention them as priority habitats. This omission is striking given the particular attention paid by this Directive to other habitats which, like this one, are associated with special substrates. The shrublands of the Gypsophiletalia order, i.e. habitat 1520 of the above mentioned Directive corresponding to gypsophilous vegetation, are a particular case in the Iberian Peninsula. The extensive study of both habitats and their flora over recent years has provided a magnificent opportunity for us to compare them, review their current state of preservation and demand that more serious attention be paid to dolomites.Key words : gypsum -flora -vegetation -gypsophilous -dolomitophilous -serpentines.Résumé.-Les buissons des Convolvuletalia boissieri sont connus depuis que, en 1953, Quézel a publié la première association dans les dolomites de la Sierra Nevada (sud de l'Espagne). En dépit de leur grande originalité floristique et éco-logique, la directive Habitats 92/43/CEE ne les cite pas comme habitats prioritaires. Cette omission est remarquable si nous prenons en considération la sensibilité extrême comme d'autres habitats qui, comme celui-ci, sont liés à des substrats spéciaux. Un cas spécial dans la péninsule Ibérique est l'ordre Gypsophiletalia, l'hábitat 1520 de la directive mentionnée ci-dessus qui regroupe la végétation gypsophile. Puisque dans les dernières années la connaissance des deux types d'habitats et de leur flore a augmenté, nous les avons comparés, revisé leur état de conservation et réclamé plus d'attention pour les dolomites.
