Dune management for coastal protection focuses on

  • B.removing the vegetation to allow the sand to move freely
  • C.replacing the dune entirely with a concrete structure
  • D.lowering the dune crest to improve the sea view

Vegetation is what converts blown sand into a stable stored reservoir. Trampling and vehicle access are the principal threats to that vegetation. Access management is cheaper than restoration. Boardwalks and fencing are the usual measures.
