Aquitaine: N2000 — Geographical entities describing the natural habitats of the site “Marais du Bas Médoc” — FR7200680 (surface)

This dataset contains the natural surface habitats zoning identified in the objective document of the Natura 2000 site “Marais du bas Médoc” — FR7200680, in the Aquitaine region. This dataset is to be used with the non-geometric table FR7200680_habitat_phyto_poly, available in the associated documents. This table contains information describing the polygons of natural habitats (typicitE, state, restoration, phytosociology, etc.), as well as the phytosociological data (habitat lists) identified in the site objective document. The objective document of a Natura 2000 site contains an inventory and biological description of natural habitats and species habitats, in particular those of Community interest. All the habitats present on the site, whether of Community interest or not, are identified and mapped. Habitat identification is based primarily on the classical phytosociological approach (classification of the Prodrome des Végétations de France and the typological benchmarks of habitats produced by the South-Atlantic CBN). Where the individualisation of elementary habitats is not possible, a zoning is demarcated, called “habitat complex” with an estimate of the relative proportion of each habitat contained in the “habitat complex” zoning.
