Environmental issues have been addressed on the basis of three different approaches. (i) The earliest is the `Human-centered' approach; it was characterized by the dichotomy between `useful' species (for Man) and pests (competitors of humans). (ii) The species-centered approach was characteristic of the 20th century and remains the most common approach adopted in many countries and by several international agencies. It is based upon the notion of outstanding species, which are designated as deserving appropriate management, in contrast to `ordinary' species. (iii) Finally, the 21st century ecosystem-based approach is the one that can best meet the challenges driven by global change and ensure the proper management of natural habitats. In contrast with indices based upon a species, or a group of species belonging to a given taxon, that may not detect a strong impact on the ecosystem, and even erroneously suggest a `good ecological status', indices based on the functioning of the entire ecosystem, from primary producers to top predators, such as Ecosystem-Based Quality Indices (EBQIs), provide a realistic assessment of the ecological status. EBQIs have already been established for northwestern Mediterranean marine ecosystems: the Posidonia oceanica seagrass meadow, underwater marine caves and infralittoral reef macroalgal forests. They are currently being developed for coralligenous habitats, saltmarshes and circalittoral coastal detritic bottoms. The ecosystem-based approach can be applied to all types of ecosystem and it is important now to extend this approach to other ecosystems and regions. Ecosystem-based management and EBQIs are not incompatible with specific management measures based upon certain iconic species, which are also part of an ecosystem. The interest of ecosystem-based management is that it is not limited to the accumulation of specific management measures for iconic species, which can be mutually incompatible.
