Both species of beachgrass are noted for their association with stable sand dunes, and observations in regions where they were introduced to coasts indicate that they build the first line of dunes on coasts (the foredunes). The plants spread rapidly – 6 to 10 feet (1.8 to 3.0 m) annually – through the sand by subsurface runners , and can ...
