BEACH AND DUNE MANAGEMENT ON THE TEXAS GULF COAST
American beachgrass is the optimal choice for the fronting sand dunes (the dune closest to the beach), because of its fast growing subsurface rhizomes (stems) and roots, which spread beneath the sand and give rise to many new plants, helping to colonize the species in dune environments. Although woody vines and trees may look more stable, beachgrass can more quickly and effectively stabilize large areas of coastal dunes and banks.

As a result, dune restoration usually begins with the establishment of pioneer plants. Dunes that are only slightly damaged may be repaired by planting vegetation in bare areas, giving stressed grasses a judicious amount of fertilizer, and protecting the area from trampling and traffic.
The beach is the sole source of sand for coastal dunes, and every single sand grain in a dune has come across the beach at some time in its history. In fact, each grain probably has made the trip many times (fig. 1) because when the wind reverses and blows offshore some of the grains go right back to the beach.
