b. Foredune Community . Uwiota paniculata (sea oats) is the most 

 abundant plant in this community. Although not always dominant (Wagner, 

 1964), it is found throughout the Banks. Next in abundance is usually 

 A. breviligulata which occurs as far south as Hatteras (Brown, 1959) 

 and is most abundant toward the Virginia border. Eventually it replaces 

 U. paniculata farther north. The abundance of these two species is 

 partly due to WPA and CCC planting activities. 



The distributions of Andropogon glomeratus (bushy beachgrass) and 

 Andropogon tittoralis are variously cited in the literature. Brown 

 (1959) reported A. tittoralis was absent from Outer Banks dunes. Biork 

 (1962) stated that A. littovalis is dominant in the dione grass community, 

 and A, glomeratus is rarely a dominant dune species. Johnson (1900) 

 noted that A. maritimus (most likely A. glomeratus) was the dominant 

 foredune species on Bogue Bank. 



Panioum amarum is a widespread subdominant from Virginia to 

 Ocracoke Island, North Carolina (Brown, 1959; Kearney, 1900). 

 Panioum amarulum is most abundant from Bodie Island, North Carolina 

 to Virginia (Brown, 1959). Both are considered poor sand binders. 



Other plants of less ecological significance reported include: 

 Croton punctatus (croton) , Cenahrus pauoiflorus (field sandbur) , 

 Cenohrus tribuloides (dune sandbur), Eragrostis speatdbilis (purple 

 lovegrass), Triplasis purpurea (purple sandgrass) , Cakile edentula 

 (sea rocket), Erigeron canadensis (horse weed). Euphorbia poly goni folia 

 (seaside spurge) , Oenothera humifusa (seabeach evening primrose) , 

 Physalis visaosa (maritime ground cherry) , Solidago sempervirens 

 (seaside goldenrod), Heterotheca subaxillaj>is (camphorweed) , 

 Heterotheca gossypina (camphorweed) , Hudsonia tomentosa (beach heath) , 

 Yujcca gloriosa (Spanish bayonet), Spartina patens (saltmeadow 

 cordgrass) , and Opuntia oompressa (prickly pear), (Brown, 1959; Burk, 

 1961; Johnson, 1900; and Kearney, 1900). 



c. Migrating Dune Community . No plants are found in areas of 

 excessive sand drift. In areas of only moderate drift fast growing 

 species (e.g., V, paniculata and A. breviligulatd) occur throughout the 

 year. During the less windy summer months, in areas of low drift, 

 annuals such as E. poly goni folia, T. purpurea, and Diodia teres 



(buttonweed) are found along with S. patens and C. tribuloides 



(Brown, 1959) . 



d. Sandflat Communities . On flat sandy areas various community 

 types occur depending upon moisture availability and salinity. Brown 

 (1959) found Typha latifolia (cattail), Spartina altemiflora (smooth 

 cordgrass), Juncus roemerianus (spike rush), Cladium jamaicensis (saw 

 grass), Pluchea sp. (marsh fleabane), Centella repanda, Sairpus 

 americana (three square), and an occasional S. patens growing on a wet 

 sandflat south of the Cape Hatteras Lighthouse.
