Figure 17.—Survival of black locust was high, but growth has not exceeded 
15 feet in 20 years. 
Beach plum was not adapted to conditions on the north Pacific 
coast. It became established but grew slowly in the cool climate 
and was susceptible to blossom blight and other diseases. 
Sand cherry is used on inland dunes but was not adapted to the 
low summer temperatures and cool wet winters of the Pacific coast. 
It was also susceptible to diseases. 
Wild rose grew slowly and produced only an ineffective open 
growth. <A few scattered plants of native rose occasionally volunteer 
in protected areas on the dunes. 
Tamarisk in many places provides permanent stabilization on dune 
areas, but it grew slowly in summer and new wood was lost in the cool 
wet winters on the north Pacific coast. 
Rhododendron and azalea are native to dune areas along the 
Pacific coast, but, when planted along with trees to provide permanent 
stabilization near recreational areas, “they are quickly appropriated by 
vacationers. Plantings are therefore not successful or permanent. 
Culture and Management of Woody Plantings 
For dune-control work, trees and shrubs must be carefully planted. 
Kind and quality of nursery stock, spacing, and date of planting are 
the important considerations. 
Seedlings of Scotch broom and shore pine are easily grown in 
nurseries. The broom is ready for planting as 1-0 stock and the pine 
as 2-0 stock. Grades for planting stock are given by McLaughlin 
and Brown (1942). Plantings made from wildlings have never 
been successful. The broom is ‘pl anted into the cover of sand- stilling 
grasses as soon as this cover has become fully effective. The best
