Yves bay and Marsh National Nature Reserve

Muddy foreshore, dry dunes and pannes, marshes and reedbeds, wet meadows, tamarisk hedges, copses and thickets... A beautiful mosaic of environments has been created. On this small corner of the coast, it is home to a multitude of animal and plant species, some of which are very rare. This area was still underwater in Roman times. Clayey sediments, dune strips and pebbles cut it off from the ocean for good around the year 1000. Man was quick to exploit the sand. This led to the creation of ditches and depressions. The water table, which has since come to the surface, has created freshwater areas that complement the brackish lagoon, which is sometimes still flooded by storms.
