Delta del Ebro - Spain
Delta del Ebro
Delta de l'Ebre
Lagoons, coastal wetlands and estuaries
This important wetland is a typical river delta that encompasses several valuable habitats such as brackish coastal lagoons and salt marshes, wetlands, coastal sandy areas and, to a lesser extent, some river islands and freshwater springs (known as "ullals"). It is the largest and most important wetland in Catalonia and one of the most remarkable, in extension and biodiversity, in the western Mediterranean; it also has great importance for the maintenance of fisheries in the region. From a biodiversity point of view the Ebro Delta has international importance, holding some halophytes and aquatic plant communities (including a large number of rare and endangered species), and several species of endemic threatened fish, although the site is particularly noted for waterbirds: the population of nesting waterfowl rises to 56,000 pairs, reaching the wintering numbers up to 200,000 individuals, and it is relevant the presence of the world’ largest colony of the endemic Audouin's Gull (60-70% of the world population).
General Characteristics, Purpose, History
Several long-term ecological monitoring programs have been carried out in the last 4 decades, involving 34 schemes on birds, butterflies, reptiles and amphibians, bats, chemical and physical parameters of water from marine bays and coastal lagoons and climate variables. The purpose of the site is to ensure the on-going of these monitoring programs and to exploit their potentialities at scientific and applied levels, as well as promote their synergies within the site and with other sites of similar features.
