The IUCN Red List of Threatened Species is widely recognised as the most comprehensive source of information on the global conservation status of plant and animal species. Red List assessments evaluate the conservation status of individual species, identify threatening processes affecting them and, if necessary, propose recovery objectives for their populations. Red List assessments can be used as a tool for measuring and monitoring changes in the status of marine species biodiversity and our knowledge of the taxa. They are an essential basis for providing targets for management priorities, and for monitoring the long-term success of management and conservation initiatives.

Currently, IUCN-Med is undertaking regional assessments of Mediterranean chondrichthyans, cetaceans, fishes, and plants.

For further details on the Red List of marine species see the Mediterranean Species Programme.
