11.5.2 The Means of Application of a ‘Seascape Approach’
to Coastal Management—Knowledge Built on the Case
of the Calanques National Park
In order to implement recommendations of this kind, various means of action are
available to the Calanques National Park authority. In particular, (1) with regard to
protection measures, the park authority has a duty to make proposals for regulatory
measures to the competent authority. In parallel, the Park regulation makes provision
for the proposal of measures on a partnership basis. These two tools could be used to
introduce protection measures specific to essential habitats, notably the nurseries of
the Sparidae; that is, measures that explicitly stipulate the intention and the means to
preserve their biotic and abiotic characteristics. Indeed, on reading the partnershipbased measures of the draft charter, it will be noted that the notion of seascape is
used, but that it remains relatively general. Future proposals for additional measures
might offer an opportunity to define precisely certain of the high priority habitats,
which are at present not specified individually on the maps of the biocenosis such
as those of Natura 2000, and which thus have not so far been taken into account
in the management plans. This is the case for the heterogeneous nursery shallow
bottoms but as well, for example, for the Cystoseira spp. forests, nursery habitat
