Name: A.1533
Reference: EcoArt 2002
Description: Dune grasslands dominated by ~Schizachyrium littorale (= Schizachyrium scoparium ssp. littorale)$. This alliance occurs on deep well-drained sands of old leveled interdunes. It usually occurs within the influence of offshore winds and salt spray. Although highly variable in species composition, the typical expression of this alliance is characterized by a predominance (25-50% cover) of bunch grasses including ~Schizachyrium littorale, Andropogon virginicus, Panicum amarum var. amarulum, Ammophila breviligulata, Dichanthelium scoparium$, and ~Dichanthelium acuminatum$. Generally one or two of these species will dominate while the others occur as more infrequent, scattered clumps. Occasionally ~Spartina patens$, growing in a dry 'wispy' condition, will form the dominant graminoid cover. Shrubs of ~Morella pensylvanica (= Myrica pensylvanica)$ are sparse, and stunted ~Baccharis halimifolia$ and ~Diospyros virginiana$ are even less frequent. Dense tangles of ~Toxicodendron radicans$ are very characteristic of this alliance as they sprawl over the bareground and sparse vegetation. ~Rubus argutus$ is also scattered throughout. Much of the remaining dry sands are exposed with sparsely distributed herbs. Characteristic herb species include ~Cirsium horridulum, Solidago sempervirens, Pseudognaphalium obtusifolium (= Gnaphalium obtusifolium), Nuttallanthus canadensis, Euthamia caroliniana (= Euthamia tenuifolia), Oenothera humifusa$, and ~Diodia teres$. This vegetation is related to maritime grasslands of New England and New York. Further analysis is required to determine the classification, and thus the range, with confidence.
