later fertilization to growth and appearance of vegetation. In the Great 

 Lakes region, plant American beachgrass during fall or early spring, at 

 one to five stems per hill, 20 to 35 centimeters deep in moist sand. 

 Space plants 45 to 60 centimeters apart or in a graduated pattern, dense 

 in the center, thinning toward the edges. Apply 100 to 150 kilograms of 

 nitrogen and 30 to 50 kilograms of phosphate per hectare in two to three 

 applications the first growing season. 



Stabilization is feasible with mats, netting, fences, etc., but vege- 

 tation is the only satisfactory long-term method. Species and practices 

 are essentially the same as for dune building. 



A tabular summary of adapted plants is presented in Table 2; a plant- 

 ing and fertilization summary is presented in Table 3.
