Résumé(disponible en anglais seulement)
Over the last decades global, European and regional policy drivers have called on countries to establish networks of marine protected areas (MPAs) as instruments for protection of marine biodiversity. These policies also require the evaluation of the exerted protection effort against specific criteria (e.g. coverage) and targets with respect to the extension of marine biodiversity elements, such as marine habitats. A pan-European map presenting the distribution of modeled broad scale seabed habitats has been recently made available through the EMODnet projecta.
The present case study illustrates the usefulness of the EMODnet habitat map in evaluating the 2009-2015 trend in MPA network coverage of seabed habitats in the north-western Mediterranean Sea. An MPA network layer, containing sites whose protection objectives include benthic habitats, was created by querying the 2009 and 2015 versions of the following reported cartographic databases: (i) European inventory of nationally designated areas - CDDA; (ii) Natura 2000; (iii) Barcelona convention SPAMIs. All sites were merged and dissolved to avoid overlaps in the MPA layer. Extraction of the modeled habitat surface areas contained in the network was analyzed for each year against the coverage targets advocated by the Convention on Biological Diversity and the EU Habitats Directive. There is decreasing habitat coverage in the network as depth progresses and bathyal and abyssal habitats fall below of the 10% coverage (see figure). This trend can be attributed to the limited deep sea protection objectives of some of the environmental policies. All of the infralittoral and most circalittoral habitats reached the 10% target by 2015 while only half of the circalittoral habitats reached the 20% target by 2015.
