Name: Ammophila breviligulata Herbaceous Alliance Reference: Eastern Ecology Working Group of... Description: Dune grasslands dominated by Ammophila breviligulata. This alliance includes maritime dune grasslands dominated by Ammophila breviligulata, Panicum amarum var. amarum, and Panicum amarum var. amarulum. Plant cover is variable, ranging from 10-75%, but is usually low. Other associated species include Solidago sempervirens, Strophostyles helvula, Triplasis purpurea, Cenchrus tribuloides, Chamaesyce polygonifolia, Oenothera humifusa, Schoenoplectus pungens (= Scirpus pungens) (where overwashed by sand), Diodia teres, Cakile edentula ssp. edentula, Nuttallanthus canadensis, Salsola kali ssp. kali (= Salsola caroliniana), Lechea maritima, and Spartina patens. Sparse individuals of stunted Morella pensylvanica (= Myrica pensylvanica) shrubs and seedlings may occur, but make up less than 2% of the total vegetation cover. Diagnostic species are Ammophila breviligulata, Solidago sempervirens, Panicum amarum var. amarulum, and Oenothera humifusa. This dune grassland community occurs almost exclusively on sandy, unstable, droughty substrates with no soil profile development. Eolian processes cause active sand deposition and erosion. The sand substrate is usually visible, and litter accumulation from plant debris is nearly absent. This community generally occurs on foredunes that receive the force of wind and salt spray, but is beyond the influence of most storm tides.  Accession Code: VB.CC.19531.AMMOPHILABREVIL Plot-observations of this Community Concept: 0
