Figure 4. Nauset Harbor (south spit), October 1969, 



Five plots were established roughly parallel to the beach in a north-south 

 direction 60 to 90 meters from the seaward shore (Fig. 5). No space was left 

 between plots to avoid creating a natural pathway for washovers. To minimize 

 error due to end or shadow effect, an extensive plot length of 150 meters was 

 used. American beachgrass was planted in plots 1, 3, and 5 on 45-, 60-, and 

 90-centimeter centers, respectively. Sand fences with side spurs were tested 

 in plot 2 and straight sand fences were tested in plot 4. There were no repli- 

 cations of the test conditions.
