Complexo Vulcânico das Sete Cidades.16/06/08; Archipiélago de las Azores; 2,171 ha; 37°51'N 025°46'W. Protected Landscape. The site is one of the greatest tourist attractions of the archipelago and includes the whole crater and catchment area of Sete Cidades on São Miguel island and the adjacent smaller mountains of Serra Devassa. Several lacustrine systems occur in the site which is composed of a dozen relatively small ponds and lakes and the famous blue and green lakes (Lagoa Azul and Lagoa Verde)  the largest of the Azores (4.38 km2 and 53.2x106 m3 of water volume). Besides the high landscape significance, the complex is important as a breeding and stopover area for some species of migrant birds at regional level, especially ducks and waders. The eutrophication of the lakes, the expansion of exotic invasive species, the intensification of grazing and livestock, as well as erosion, are the main threats to this site, which is under a urgent recovery plan for its restoration. Ramsar site no. 1802. Most recent RIS information: 2008.
