what can be done to prevent the migration of beach dunes
Sand dune stabilization Stabilizing dunes involves multiple actions. Planting vegetation reduces the impact of wind and water. Wooden sand fences can help retain sand and other material needed for a healthy sand dune ecosystem.[1] Footpaths protect dunes from damage from foot traffic.[2]
Siesta Beach Unlike beaches elsewhere that are made up mostly of pulverized coral, Siesta Beach's sand is 99% quartz, most of which comes from the Appalachian Mountains.[3] Even on the hottest days, the sand is so reflective that it feels cool underfoot. It's estimated that the sand on Siesta Beach and Crescent Beach on Siesta Key is millions of years old, having its origin in the Appalachians and flowing down the rivers from the mountains until it eventually was deposited on the shores of Siesta Key.
