This dataset compiles wetlands mapped during municipal inventories of wetlands and watercourses conducted between 2009 and 2014, as part of the implementation of the 2009 Loire Estuary SAGE (local water management plan). To improve homogeneity, the wetlands were characterized using a common methodology across the territory covered by the plan. The data is published via the Pays de la Loire regional open-data portal and provides a georeferenced inventory of wetland areas, useful for water resource management, land-use planning, and environmental protection studies within the Loire Estuary catchment area in France.Donnée issue de la compilation des zones humides cartographiées lors des inventaires communaux des zones humides et des cours d'eau réalisés entre 2009 et 2014 dans le cadre de la mise en œuvre du SAGE* Estuaire de la Loire de 2009.
