Notes
Marram (A. arenaria) is native to the coast of Europe and North Africa, from Scandinavia south to the Mediterranean Sea, and from Ireland east to Egypt.
American beach grass (A. breviligulata) occurs on the coasts of eastern North America, including the shores of the Great Lakes.}}
Both species occur in sand dunes, often dominating the early stages of development. They are especially adapted to burial by sand and are drought resistant. They initiate foredune growth on flat beaches and stimulate the development of high/steep foredunes. Roots extend one to several meters deep.
