American Beach Grass is a perennial grass found on beaches or sand dunes. Mature plants are between 2-4 feet tall and spread vegetatively forming large colonies. Each plant grows as a small clump with leaf blades that split near the base of plant. American Beach Grass blooms in late spring and summer. Its flowering spikes are long and skinny, measuring 6-14 inches long and less than an inch wide. (Hilty 2017) American Beach Grass is found on the West and East coasts of North America, and on the margins of the Great Lakes. Despite this seemingly large range, is of conservation concern because it is restricted to very sandy, beach and dune habitats. It plays a significant role in these habitats by stabilizing the sand dunes, which eventually allows other species to colonize the habitat as well. (USDA and NRCS 2017, TWC Staff 2017) Nancy Sather of MN suggested this taxon for inclusion in the MWRTF Action Plan.
