species frequency in the community was divided by the total for all species 
and the result multiplied by 100 to yield relative frequency expressed as a 
percentage. The relative frequency values were then used to compare the 
species composition of each community with the other communities, using the 
Index of Similarity (IS), IS = 2w/(a + b) (Bray and Curtis, 1957). The IS 
values were then subtracted from 100 to yield the Index of Dissimilarity 
(ID), ID = 100 -IS, and used to locate the communities along an axis by 
means of Beals' (1960) adaptation of the Pythagorean Theorem, x = (L2 + 
(dA)2 - (dB)2)/2L, and the technique of Bray and Curtis (1957). The modi- 
fied standard axis extraction technique of Levy (1976) was employed. Levy's 
(1976) procedure for axis extraction is to sum the ID values for each vege- 
tational unit. The stand with the highest sum is deemed the end of an axis; 
the opposite end of this axis is the stand least like it (i.e., having the 
highest ID in relation to the stand with the highest sum). The units are 
represented as points separated by a scale distance equal to the ID value. 
All other points are then located between the end points. 
e. Permanent  Quadrats. Three 5-meter x 5-meter quadrats were 
reestablished in each of Levy's (1976) nine defined communities, one in his 
wetlands community and one in the spurge-sandgrass community. The locations 
of the quadrat markers were determined by measuring the direction and 
distance from the U.S. Army Corps of Engineers (USACE) survey markers, 
following the procedure of Levy (1976). In addition, a permanent quadrat 
was established in the following newly recognized communities: sound-side 
disturbed-herbaceous, bulrush wetlands, reed wetlands, interdunal marsh, 
roadside disturbed, and sandgrass. Oceanside shrub permanent quadrat 3 had 
to be relocated as this site is now occupied by the FRF. The new location 
was chosen to best represent the conditions that would have been expected to 
exist at the original location had construction not occurred. The permanent 
quadrat marker established for the roadside disturbed community has recently 
been destroyed by new construction subsequent to the completion of field 
activities. Vegetative patterns, grass composition, and percent ground 
cover were analyzed, mapped, and compared to Levy's (1976) results. 
Permanent quadrat locations are listed in Appendix A. 
III. RESULTS 
ales Floristics. 
The flora was composed of approximately 180 species and 151 genera, 
representing 58 families. Levy (1976) identified approximately 178 species 
and 132 genera, representing 58 families. The list of species collected is 
presented in Table 2, with asterisks indicating the species not found by 
Levy (1976). Species found during Levy's (1976) study but not during the 
present study are shown in Table 3. 
2 Vegetational Studies. 
a. Phytosociology. Studies indicated that 14 community types can be 
delimited. Physiognomically, communities fell into three broad dominant 
categories: (1) grasses and forbs, (2) shrubs, and (3) small trees. The 
first category included communities on dry sites, which were designated the 
foredune, low dune, oceanside intershrub, planted bitter panicum, roadside 
disturbed, sandgrass-buttonweed, sound-side disturbed-herbaceous, and sand-
