<P> Ammophila breviligulata ( American beachgrass or American marram grass ) is a species of grass that is native to eastern North America , where it grows on sand dunes along the Atlantic Ocean and Great Lakes coasts . Beachgrass thrives under conditions of shifting sand , sand burial , and high winds ; it is a dune - building grass that builds the first line of sand dunes along the coast . Beachgrass is less vigorous in stabilized sand , and is only infrequently found further inland than the coastal foredunes . Ammophila breviligulata was introduced to the Pacific coast of North America in the 1930s . It is proving to be invasive , and is increasingly important to coastal ecology and development in Oregon , Washington , and British Columbia . </P>
