Dune regeneration refers to the restoration or natural rebuilding of sand dunes in coastal areas. This process typically involves planting native dune vegetation, fencing off dunes to protect them from erosion, and allowing natural processes to help rebuild the dune ecosystem. Dune regeneration is important for preserving coastal habitats, protecting against erosion, and providing a buffer against storm surges.
