| Resumo: | The cartography of benthic communities is, today, essential to promoting adequate strategies for the use, management and conservation of littoral areas, especially if they are large protected zones. In each zone, cartography is necessary to elaborate a management zoning map, depending on the ecological value of the different benthic communities established and on the local geographical distribution. The methodology used in the elaboration of a map including the benthic communities of the Straits of Gibraltar (0-30 m depth; 40 km of littoral extension), in spite of the complexity of these kinds of objectives, represents an approach to the cartography of the submarine sessile biota of large littoral zones of protected areas. The present study combines physical data (bathymetry and type of substrate), collected using acoustic techniques, and biological data (benthic communities), collected during an intensive sampling programme using scuba (hard bottom: image analysis) and dredging (soft bottom: granulometry and benthic fauna). The information has been geoindexed to be inserted, as different layers, into a Geographic Information System (GIS). |
