grass communities, as well as some on wet sites namely: the interdunal 
marsh, reed wetland, and bulrush wetland communities. The second category 
was represented by the sound-side disturbed-shrub and the oceanside shrub 
communities. The third category included only the sound-side shrub 
community (Levy, 1976) which was dominated by tree species. The 
phytosociological data for these stands are presented in Appendix 
B. Biomass data from the four sampling periods are summarized in Table 4. 
The shrub- and tree-dominated communities had the greatest number of 
species: sound-side disturbed-shrub, 173; oceanside shrub, 16; and sound-side 
shrub, 14. Among the forb-grass dominated communities, the bulrush wetlands 
community had the highest number of species, 13; the reed wetlands had the 
lowest number of species, 3. 
The highest standing crop was measured for the reed wetland community 
during the September collection (999.6 grams per square meter, Tables 4 and 
BeliQ))ye Six communities had peak standing crops during the September 
collection period (e.g., foredune, roadside disturbed, bulrush wetland) and 
five during the November period. The sandgrass-buttonweed community had its 
peak standing crop during the July sampling (Tables 4 and B-30). Three com- 
Munities (i.e., low dune grass, oceanside intershrub, planted bitter 
panicum) had values that did not appear to be greater in November than those 
measured for the September period. The sandgrass and interdunal marsh com- 
munities were barren during the first collecting period and were recognized 
aS unique vegetative assemblages only after the September collections were 
completed. 
As noted in the procedure for community sampling, biomass data were not 
obtained for the oceanside and sound-side shrub communities following the 
approach of Levy (1976). The oceanside shrub community had a total density 
of 26.4 individuals per quadrat while the sound-side shrub community had a 
value of 5.6 individuals per quadrat. 
b. Vegetational Map. The vegetational map of the study area is pre- 
sented in Figure 2. For comparison, Levy's (1976) vegetational map is shown 
in Figure 3. A summary of the approximate number of acres of each com- 
munity, the barren dune areas, roadways, etc., is presented in Table 5. 
Area measurements in Levy (1976) are cited as +10 percent. The method 
employed in this study is of a similar precision. The larger acreages meas-— 
ured in this study may be accounted for, at least in part, by the subsequent 
marsh grass (Phragmites and Spartina) and dune grass (Pantcum and Ammophila) 
plantings by the Army Corps of Engineers. The FRF covers 71 hectares (175 
acres) (Birkemeier, et al., 1981) of which 57.3 hectares (141.7 acres) are 
vegetated, 6.6 hectares (16.3 acres) are barren dunes, 1.5 hectares (3.7 
acres) are hard-top roads and buildings, with the remainder composed of 
beaches and periodically submerged sandy bottoms. 
Ch Community Ordination. The results of the ordination techniques 
are presented in Figures 4, 5, and 6. The three-dimensional aspects of 
this model were depicted by graphing two axes at a time. The distances 
between individual communities were related to the relative differences
