Since 1992, underwater fishing is forbidden in the islands. National Parks are nature areas nearly untransformed by human activity that, based on their landscape, geological or ecosystems possess aesthetic, ecologic, educative or scientific values worth of special protection. Therefore, the activities that alter or endanger the stability of the ecosystem are forbidden. Some traditional activities (like traditional fishing) are allowed as long as they are compatible with the environment and the preservation of natural resources. Since 1988, the Islands have a status of ZEPA (Zona de Especial Protección para las Aves, Spanish for Special Protection Area for Birds), and they are included in the Natura 2000 network, which develops European Union Directives in relation to habitats and birds.
