Figure 5.—Trees and shrubs protect this beach access road against erosion. 
Principal highways parallel most coastal dune areas, and access 
roads to the beaches cross the dunes. Trees confine the traffic to the 
roads and provide additional protection from wind erosion (fig. 5). 
An understory of fruit-bearing shrubs and vines also enhances the 
public use of the area (fig. 6). 
Food and cover for wildlife are provided in shrubs and trees. 
And when the proper species are planted there are more upland 
game birds, waterfowl, and game animals. One such area on the 
north Pacific coast has been declared a game refuge (fig. 7).
