New Aquitaine partial: DREAL Wetlands — Perimeters (surfacic)

This dataset contains the wetlands (surface objects) of New Aquitaine. ATTENTION: this dataset is not exhaustive on the perimeter of Nouvelle-Aquitaine, it concerns the perimeter of the former Limousin region. Wetland according to the Water Act (1992): Wetland means land, whether or not exploited, usually flooded or sprinkled with fresh, salted or brackish water on a permanent or temporary basis; vegetation, where it exists, is dominated by hygrophile plants for at least part of the year; The criteria for defining wetland delimitation have been clarified in the Ministerial Orders of 24/06/2008 and 01/10/2009. The wetlands present in ex-Limousin are of great diversity. For the sake of simplification, they were grouped into 18 main types. This grouping was carried out by crossing physionomic information (vegetation aspect) and phytosociological information (floristic composition of vegetation). These two criteria are essential and allow for a concrete approach to the wetland. Be careful, a hasty determination, taking into account only the physiognomy for example, can lead to an error of #x27; identification of the habitat. This is particularly true in the case of vegetation dominated by the Jonc diffusus (Juncus effusus). The same physiognomy may belong to different phytosociological groups. __Origin__ This dataset was created on the perimeter of the Nouvelle-Aquitaine region during the construction of ' harmonisation of heritage, it is produced from the \#x27; assembling the data of the 3 former regions Aquitaine, Limousin and Poitou-Charentes. ATTENTION: this dataset is not exhaustive on the perimeter of Nouvelle-Aquitaine, it concerns the perimeter of the former Limousin region. Study carried out from 2002 to 2007 on behalf of DIREN by the National Botanical Conservatory of the Massif Central (CBNMC). __Partner organisations__ DREAL Nouvelle-Aquitaine __Links annexes__ * [basketDownloadFrontalParametrage](https://catalogue.sigena.fr/geosource/panierDownloadFrontalParametrage?LAYERIDTS=3714410) [See this page on geo.data.gouv.fr](https://geo.data.gouv.fr/fr/datasets/a2b24878677abd1c1be97464bfd1d286f5113653)
