Caldeira do Faial. 16/06/08; Archipiélago de las Azores; 312 ha; 38°35'N 028°42'W. Nature Reserve, Sitio de Importância Comunitária SIC. A big circular depression created by a volcanic explosion situated in the central part of Faial Island. The caldera, 390 metres deep, is in good conservation status and supports different wetland types with species native and endemic to the Azores and Macaronesia, as well as laurel forest. It hosts unique wetland ecosystems including mires, forested and non forested peatlands, seasonal freshwater marshes and streams. The presence of many endemic invertebrates and some threatened plant species (Bellis azorica, Lactuta watsoniana, Veronica dabneyi and Isoëtes azorica) confers high ecological importance to the site. The wetland is also very important in the island context for the hydrological value as supplies freshwater to the inhabitants. It also has scenic and tourist value, being one of the main attractions of the island. Ramsar site no. 1799. Most recent RIS information: 2008.
