The beach of Pampelonne, on Saint-Tropez Peninsula, has been redeveloped since 2019 in order to preserve the coastline. A 37-acres (15 ha) dune cordon was established to limit maritime erosion. The sand in the dunes has been fixed through the cultivation and replanting of cuttings of different native plant varieties. The area is now home to sand oyat, sea holly, dune spurge, sand lily, sea knotweed, or branched romulea.
