The three research sites were subdivided into five plots (see Sec. II) . A £>. 



total of 2,567 quadrats were sampled within the five plots during the summer v": 



of 1977. The most extensively covered were the washover throat and fan of w -\ 



site 1. Vegetative changes, followed since 1972 at this site, presented a , - : " 



unique opportunity to study the revegetation of a washover fan. Site 1 has p*, 



actively overwashed during severe stonas and has trapped sufficient sand on i£ 



sections of the fan surface to attain an elevation above spring high tides and (\< 



maintain a dune community. Twenty transects 100 meters long were sampled at V>" 



site 1 throat for a total of 1,020 quadrats. Twenty-eight transects 50 meters o'- 



long were established at site 1 fan; a total of 728 quadrats were sampled. &-' 



Notes were made to indicate which quadrats were located in areas affected by "*^ 



overwash and which were located on the adjacent salt marsh. Nine transects ."-* 



were set at site 2, and 234 quadrats were sampled. At site 3, 351 quadrats ■'-.- 



were sampled in the dunes and 234 quadrats were sampled in the salt marsh f-.^ 



along 13 transects. A field map was made of each plot using the 5- by 5-meter '."■• 

 flagged elevation grid as a guideline.

a severe northeaster in February 1972. The washover consisted of a throat p** 



which meandered through the dune line and a small fan-shaped deposit on the •—r.
