Dune fences are structures built along sandy coastal areas to help control erosion and protect the landscape. They are typically made of wooden slats or posts and are designed to trap sand blown by the wind, allowing it to accumulate and form natural dunes. These fences play a crucial role in maintaining the stability of coastal ecosystems. In addition to preventing erosion, dune fences also provide habitat for various wildlife species. By creating sheltered areas, they support plants and animals that thrive in sandy environments. Overall, dune fences are an important tool in coastal management and conservation efforts.
