A new site, Site E, has moderate wind, high vegetation cover, and extensive surface crust. What is the most likely outcome for dune migration at Site E?

High vegetation cover and an extensive surface crust help hold sand in place and resist erosion. With only moderate wind, these protective factors are likely to outweigh the forces moving sand, so dune migration would be low. The best choice is “low dune migration because protections outweigh erosional forces.”
