were located in the barren dune areas. Only one quadrat was located in 

 both the wetlands community and the spurge-sandgrass community due to 

 their small extent and unifonnity. The quadrats were laid out 

 diagonally north and south and oriented with a permanent survey 

 marker in the east comer. Locations of the permanent quadrat 

 markers were determined by measuring direction and distance to the 

 nearest geographic monument marker. Vegetative pattern, gross 

 composition, and percent ground cover for each permanent quadrat were 

 determined and mapped on graph paper. 



III. RESULTS 



lo Floristics. 



The flora is composed of approximately 178 species and 132 genera, 

 representing 58 families. The list of species collected (with their 

 common names when applicable) is presented in Table 1. 



2, Vegetational Studies . 



a. Phytosociology . Studies indicate that 11 different community 

 types can be delimited. Some of the community types are very distinct, 

 i.e., foredune, oceanside shrub, sound-side shrub, and wetlands. The 

 sound— side disturbed community is relatively distinct, but the 

 remaining six community types are qualitatively, and in some cases, 

 quantitatively similar. The phytosociological data for these stands 

 are presented in Tables 2 through 12. 



The sound-side shrub community (Table 8) has the greatest number 

 of species (28), followed by the sound-side disturbed community (24) 

 (Table 10), and the wetlands community (22) (Table 11). The oceanside 

 intershrub community (Table 3) had 16, while the planted American 

 beachgrass (Table 5) and low dune grass (Table 7) communities each had 

 10; the remaining communities had 7 species each except for the 

 planted bitter panicum community (Table 9), which had only 6. 



The oceanside shrub community (Table 4) had the greatest biomass 

 with 2779.3 grams per square meter dry weight. Though biomass data 

 were not obtained for the sound-side shrub community (Table 8) due to 

 the impractical ity of cutting down the few trees and large shrubs, its 

 density of 36,9 individuals per square meter for all species, and 

 especially its density of M. pensytvanioa (15), Prunus serotina (black 

 cherry) (8), Sassafras afbidim (sassafras) (2.4), and Drospyros 

 virginiana (persimmon) (4.4) suggest that the standing crop biomass 

 of this community is of the same magnitude as that of the oceanside 

 shrub community. The wetland community (Table 11), which had the 

 second highest measured biomass, had only 104,9 grams per square meter. 

 The remaining values ranged from 68,8 grams per square meter for the 

 sandgrass-buttonweed community (Table 6) to 5,6 grams per square meter
