This is from the book: Plants from the Oregon coastal dunes.

On the foredune and other areas of active, blowing sand, the continued spread of European beach-grass (Ammophila arenaria) has resulted in the suppression of the native dune-building and stand-stabilizing species. While not generally threatened with extinction, many of these species, such as the yellow abronia (Abronia latifolia), gray beach pea (Lathyrus littoralis), beach morning-glory (Calystegia soldanella), American dune-grass (Elumus mollis)and large-headed sedge (Carex macrocephala) are no longer seen in the abundance of thirty years ago. One endangered species pink sandverbena (Abronia umbellata ssp. breviflora) which was once abundant along the coast from British Columbia to northern California is now restricted to a few sites from the central Oregon coast south. Since 1991 efforts have been underway by the Plant Conservation Biology Program of the Oregon Department of Agriculture to reintroduce this species to create new populations. Reintroduction has been most successful in sites where European Beach-grass has been brought under control.
