Dune stabilization protects soil from wind erosion primarily through the conservation and management of the plant community living on the dunes.1

This process functions in two main ways:
* Surface Protection: The upper parts of the plants act as a physical barrier that shields the soil from the direct force of surface winds, reducing the wind's ability to dislodge and transport soil particles.12
* Root Anchoring: The plants develop extensive root networks below the surface that bind the soil together, creating an underground web that holds the sand in place.13

By maintaining this vegetation, such as tough perennial marram grass, the soil is effectively anchored, preventing the shifting and floating of sand that characterizes unstable dunes. This stabilization is a critical technique in combating desertification and preserving land productivity.231
