FP STABLISHING and maintaining permanent vegeta- 
tion has proved to be the most effective and efficient 
means of stabilizing coastal sand dunes. The dune 
areas on the Pacific coast of North America are the re- | 
sult of accelerated erosion caused primarily by the de- 
struction of a cover of native vegetation. In some areas 
the climax cover was herbaceous, in others it was woody, 
and in still others it was a combination of herbaceous and 
woody plants. The choice of plants for the reconstruc- 
tion of a permanent cover depends on the inherent limi- 
tations of the site and the intended land use for the area.
