Stewardship Overview: Ammophila arenaria threatens coastal sand dunes in the eastern and western United States. It displaces native dune species and significantly alters the morphology of dune systems where it invades. Successful management of coastal sand dune elements requires the control of this aggressive species.
The spread of A. arenaria can be controlled through manual removal, but this type of control requires on-going treatment. Control should be emphasized until eradication techniques are refined. Further research is a high priority and is currently being carried out by Humboldt State University, California.
