In 1977 the area was sparsely vegetated (bare sand, 99 percent cover). 

 Ammophila brsviligulata (l.V. - 144. A) and Spartina patens (l.V. « 124.2) were 

 the dominant species. The mean elevation of site 1-F-w was raised 72 centi- 

 meters between 1977 and 1978. Although site l-F-w-77 was an embryonic dune 

 area, the relief of the area was greater after the atoria (o » 0.21 seter), 

 since large drift piles were deposited on the washover fan. Of a total of 

 303 quadrats sampled, 61 quadrats were vegetated in 1977 versus 25 that were 

 vegetated in 1978. Four common drift-line species (.Ammophila bveviligulata, 

 Lathy tub japonicus , Cakile edentula, Ar-iemisic etslleriarui) were found in both
