As part of the program to remove sand from the beach at Saint Martin en Campagne, an agreement has been signed between EDF and the commune of Sainte Marguerite Sur Mer to provide a permanent home for sea cabbage, a protected species of flora (Crambe Marina) at the foot of the cliff, before the last eastern spur of the beach.

A public information board will be set up when the sea cabbages are planted, scheduled for autumn 2018.
