a. Beachgrass Plots . American beachgrass plantings were conducted between 

 April and November 1970. The beachgrass was wild-harvested from existing stands 

 on Nauset Beach near Nauset Heights. Harvested plants were separated into 

 single sprigs (single stems with attached root material) and planted — three to 

 five sprigs per hill. 



b. Fence Plots . A single, straight sand fence was constructed in plots 



2 and 4 in April 1970. In plot 2, 3-meter side spurs were added perpendicular 

 to the straight fence at 15.3-meter intervals on alternate sides of the fence. 

 Additional lifts of fence were constructed in both plots in January 1971 



(second lift), April 1971 (third lift), and January 1972 (fourth lift). The 

 second lift was placed about two-thirds of the way up the slope of the sand 

 accumulated by the first lift. The third and fourth lifts were placed on the 

 seaward and landward sides of the newly formed dune, respectively. In plot 2, 

 side spurs' were added on alternate sides of the second lift, only on the sea- 

 ward side of the third lift, and only on the landward side of the fourth lift 



(Fig. 6). In April 1972 after the fourth lift had filled with sand, plots 2 

 and 4 were planted with American beachgrass on 60-centimeter centers, three to 

 five sprigs per hill.

3, Maintenance . 



Parts of the planting areas in which survival was low were routinely re- 

 planted: plot 1, remedial planting in October 1971 and April 1972; plot 2, 

 remedial planting in April 1973; plot 3, remedial planting in October 1971; plot 



4, remedial planting in April 1973; and plot 5, remedial planting in October 

 1971 and April 1972. Although experimental planting was discontinued after 1973, 

 local volunteer groups have continued to provide periodic maintenance.
