There is a significant linear relationship (P < 0.05, r «= 0.245) between 

 initial (1977) Ammophila bveviligulata cover and final (postoverwash, 1978) 

 cover for recovering quadrats. The initial cover data mean for quadrats that 

 failed to recover (x = 21 percent cover) was significantly lower than the 

 initial cover data mean for recovering quadrats (x = 31 percent cover; Fig. 

 42). Forty-eight percent of the quadrats (19) that failed to recover had 

 cover values of less than 10 percent; 29 percent of the recovering quadrats 

 (20) had 1977 cover values less than 10 percent. The recovery of quadrats 

 with very low preoverwash Ammophila bveviligulata was less than quadrats with 

 higher cover values.

 for quadrats in which plants did not recover 

 froo burial does differ significantly from 

 the rank mean for quadiats In which plants 

 did recover (P < 0.05).

 bveviligulata that recovered and failed to recover from burial. 



There is also a significant linear relationship between initial and final 

 density for recovering quadrats (P < 0.01, r = 0.562). Initial density for 

 recovering quadrats was highly significantly greater than nonrecovering 

 quadrats (Fig. 43). Eighty percent of the nonrecovering quadrats had fewer 

 than five plants before the storm, while 56 percent of the recovery quadrats 

 initially had fewer than five plants.
