Preventing Sand Dune Erosion: Vegetation, Fencing, and Management

Effective dune stabilization combines multiple strategies:

• Vegetation planting: Deep-rooted grasses and native plants anchor sand, reduce wind speed, and promote accumulation.
• Sand fencing & barriers: Slatted fences, brushwood, or geotextiles trap windblown sand, rebuilding dunes.
• Dune reshaping: Grading slopes, smoothing blowouts to reduce erosion vulnerability.
• Sand replenishment: Adding sand from offshore or inland sources to restore volume and profile.
• Windbreaks & shelterbelts: Rows of trees/shrubs reduce wind energy reaching dunes.
• Limiting human activity: Restricting ORVs, foot traffic, and development in sensitive zones.
• Integrated management plans: Coordinated, science-based strategies involving stakeholders ensure long-term resilience.

Success depends on site-specific conditions and sustained commitment.
