Abstract
Defining a reference ecosystem for ecological restoration project is an essential step. The reference can correspond to the historical ecosystem, can be defined to solve environmental issues or can correspond to a socioecosystem. For the restoration of the Cassaïre site in the Camargue delta in southern France, the reference ecosystems chosen are : Mediterranean temporary wetlands and Mediterranean meso-xeric grasslands. The choice of these two reference ecosystems appears logical considering their contribution to regional biodiversity. Temporary wetlands and meso-xeric grasslands are rare, adapted to the Mediterranean climate, seriously endangered and host a high species richness. They are potentially achievable restoration targets because patches of these ecosystems remain in the Camargue area and close to the Cassaïre site. Moreover, an ecological history approach reveals deep human imprints on ecosystems and ensures that historical restoration targets (the state prior to human impacts) cannot be reached, because they are associated with hydraulic functioning (flooding of the Rhône and Durance) that no longer exists. The restored site is planned to be suitable for livestock grazing, thus presenting a new agricultural opportunity, while simultaneously offering new services, such as hunting.
期刊介绍:
ecologia mediterranea publie des articles de recherche originaux sur des sujets se rapportant à l’écologie fondamentale ou appliquée des régions méditerranéennes. La revue exclut les articles purement descriptifs ou de systématique. ecologia mediterranea peut publier des études plus descriptives si elles apportent des connaissances approfondies d’intérêt général pour les écologues. ecologia mediterranea privilégie les domaines scientifiques suivants : bioclimatologie, biogéographie, biologie de la conservation, biologie marine, biologie des populations, écologie des communautés, écologie forestière, écologie génétique, écologie marine, écologie microbienne, écologie du paysage, écologie de la restauration, écologie végétale et animale, écophysiologie, paléoclimatologie, paléoécologie. La revue accepte également des articles de synthèse, des notes / communications courtes, des comptes-rendus d’ouvrages, des résumés de thèse, ainsi que des commentaires sur les articles récemment parus dans ecologia mediterranea . La revue publie aussi des actes de colloques faisant l’objet d’un numéro spécial. Dans ce cas, prendre contact avec les éditrices.
