◼ Ammophila arenaria is the European variety of beach grass. It produces the taller dunes.
◼ Ammophila brevigulata is the American version that is native to the east coast and great lakes region. It produces a dune approximately half as tall as its European relative depending on offshore sand deposits.
◼ Both have been planted on the west coast as late as the early 1980’s to slow sand migration onto roads homes and wildlife areas using Federal, State and local resources.
◼ Elymus mollis is a west coast native beach grass that grows in very sparse densities and does little to slow inland sand migration.
◼ Coastal wetlands and forests are supported by taller more stable dunes. Native plants are known to have very diverse and abundant populations behind ammophila covered dunes.
◼ Ammophila dunes trap sand and move west (terrestrialize) adding land to our coastline.
◼ Removal of ammophila has proven to displace this accumulated sand and allow winds to carry a large amount of sand east into established wetlands, nature areas and various important public and private infrastructure.
◼ There has been no peer reviewed science that has determined that ammophila removal has benefited populations of the western snowy plover.
◼ There are photographs in the snowy plover recovery plan and the 1999 RU2 annual report that show snowy plover nests in clumps of ammophila
◼ It costs approximatly $38 000 per acre to remove ammophila.
◼ School children have generated $17 85 per hour of volunteer labor as matching funds for grants for Friends of the Dunes in their vegetation removal programs.
