Marais rétro-littoraux de l'Estuaire de la LoireRetro-littoral marshes of the Loire Estuary
This dataset delineates the retro-littoral marshes within the boundary of the Loire Estuary SAGE (local water management plan), a coastal planning area in the Pays de la Loire region of France. Retro-littoral marshes are flat, low-lying coastal areas with poor drainage that are frequently flooded, and whose ecology, land use, infrastructure and landscapes are strongly shaped by this hydrological regime. The dataset is published as open data via the Pays de la Loire regional open-data portal and can be used for spatial planning, water management and environmental analysis of the estuary's marshland areas.Délimitation des marais rétro-littoraux dans le périmètre du SAGE Estuaire de la Loire. Les marais rétro littoraux correspondent à des régions côtières plates et humides, insuffisamment drainées et souvent inondées dont la nature, les activités, les aménagements et les paysages sont fortement et...
