Beach grass. Beach grass (genus Ammophila), also called marram grass, psamma, or sand reed, genus of two species of sand-binding plants in the grass family (Poaceae). American beach grass (Ammophila breviligulata) grows along the Atlantic coast and in the Great Lakes region of North America. European beach grass (A. arenaria) is native to temperate coasts in Europe, northern Africa, and western Asia and has been introduced in many places as a dune stabilizer.
Dune Stabilization. Beach grasses help keep a sand dune in place when the grass roots run deep and the grass has grown tall enough to act as a natural wind barrier. When winds blow, more sand accumulates in the grassy areas of the dune.Over time, the grass propagates, resulting in even more grass coverage and erosion control.he root system of beach grasses also helps prevent erosion. Roots clump sand beneath the surface in much the way blades of grass trap airborne sand.
