  • The Biosphere Reserves are samples representing of marine, land or coastal ecosystems, promoting solutions to reconcile the conservation of biodiversity with its sustainable use. Internationally recognized (UNESCO Man & Biosphere Programme), designated by national governments and remaining under sovereign jurisdiction of the states where they are located. Throughout its zonation (core, buffer and transition) have to promote three functions: conservation of natural and cultural heritage, sustainable development, dissemination and knowledge. Only the core area requires legal protection and may correspond to a pre-existing protected area as a reserve or natural park. This dataset relates only to the marine and/or coastal biosphere reserves.
