what is the grass on the beach called
Ammophila breviligulata 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.
Waikiki Over time, Waikīkī beach has had problems with erosion, leading to the construction of groynes and beach replenishment projects. For example, in the 1920s and 1930s sand was imported from Manhattan Beach, California, via ship and barge to Waikīkī.[12] Importing stopped in the 1970s. Officials are looking for ways to sustain the existing sand by eliminating loss due to tidal flow.[13] Subject to permits, a partial restoration was completed in the spring of 2012. The proposed project imported sand from nearby shoals and widened the 1,700-foot (520 m) long beach by about 37 feet (11 m) between the Royal Hawaiian Hotel concrete groyne and the Kūhiō Beach crib wall. The project restored the beach to its 1985 shoreline.[14]
