Name: Morella pensylvanica - (Prunus maritima) Shrubland Alliance Reference: Eastern Ecology Working Group of... Description: Dune thickets of the Mid-Atlantic Coast; this alliance includes maritime shrublands dominated by Morella pensylvanica (= Myrica pensylvanica), with Baccharis halimifolia, Rhus copallinum, and stunted individuals of Pinus taeda. Prunus maritima is characteristic of this community from Maryland to the north. The constant movement of sand in this community limits the herbaceous cover. Typical herbaceous species include Ammophila breviligulata, Cenchrus tribuloides, Chamaesyce polygonifolia, Cyperus grayi, Dichanthelium acuminatum, Diodia teres, Hudsonia tomentosa, Lechea maritima, Oenothera humifusa, Panicum amarum var. amarulum, Parthenocissus quinquefolia, Rumex acetosella, Solidago sempervirens, Spartina patens, Toxicodendron radicans, and Triplasis purpurea. This maritime shrubland usually occupies the intermediate areas between the very unstable oceanward portions of the dunes and the more protected backdunes, where it forms partially open to dense shrub thickets. The substrate is sand with no soil profile development, and with variable amounts of accumulated leaf litter. Where this community occupies the lee side of foredunes, greater exposure to winds and storms contributes to a shorter stature and more open aspect of the vegetation. Here there are large patches of open unvegetated or sparsely vegetated sand.  Accession Code: VB.CC.22067.MORELLAPENSYLVA Plot-observations of this Community Concept: 0
