Land Ecosystems 



Dune Community 



This major community type fringes the Atlantic Ocean 

 encompassing the frontal dune complex which extends from the 

 ocean side base of the foredune, inland through the often closely 

 spaced, smaller, hummocky dunes. 



The community is usually dominated by perennial grasses 

 with an occasional shrub or wind-shorn tree in protected areas. 

 All of the species which persist here must have a certain degree 

 of physiological salt tolerance to both salt spray and substrate 

 salinity. They also must be able to withstand high winds and 

 sand blasts, possess drought resistance, and be able to tolerate 

 low levels of certain nutrients such as nitrogen. Physiologically, 

 this is perhaps the harshest environment in the Atlantic Coastal 

 Plain. 



Due to this harsh environment, the vegetation is sparse 

 with sea rocket Cakile spp ., pigweed Amaranthus pumila and saltwort 

 Salsola kali occurring on the beach and several grasses dominating 

 on the dunes. American beachgrass Ammophila breviligulata , salt- 

 meadow cordgrass Spartina patens , silver bunchgrass Panicum 

 amarulum and running beachgrass Panicum amarum are the dominant 

 grasses in the dune community. Herbaceous species gaining 

 importance behind the foredune include beach pea Strophostyles 

 helvola, sandbur Cenchrus tribuloides . seaside spurge Euphorbia 

 polygonif olia and various broomsedges Andropogon spp . 



Typical animals include: 



Horseshoe crab Limulus polyphemus 

 Ghost crab 

 Coquina clam
