Salt marshes and meadows

All along the Bassin d’Arcachon, you can discover spaces living to the rhythm of the tides, numerous nature reserves rich in fauna and flora, in a “marsh” type environment, typical of the Atlantic Coast. The salty meadows are mudflat vegetation, rich in sediments, with a rare biodiversity.

They have allowed man to set foot towards the ocean, by taming these natural environments. These coveted environments are the result of an almost imperceptible elevation of the seabed by sedimentation facilitated by pioneer vegetation, in the lower fringe of the shore. This is where people came to graze the sheep, collect shells, collect the sea lines, and set nets. It is also there that the first dykes were erected, then leaving it to the shore to form a new green seafront in a few decades. And the story started again. These particularly rich environments also have incalculable virtues: not only do they serve as living or feeding grounds for species that we exploit elsewhere (coastal fishing), but they have physical coastal protection properties that are irreplaceable.
