Marram grass (ammophila breviligulata) carpet on the back of a sand dune in Greenwich Peninsula.
Prince Edward Island National Pa, Prince Edward Island, Canada
Sand dunes are created by the wind and waves that carry dry sand up onto the beach where it collects behind rocks or clumps of seaweed. The roots and rhizomes of marram grass create those wonderful nets of vegetation, that further help in keeping the structure of the sand dune.
