Name: Hudsonia tomentosa Dwarf-shrubland Alliance Reference: Eastern Ecology Working Group of... Description: This alliance consists of sandy or rocky areas dominated by Hudsonia tomentosa. This alliance is largely confined to maritime interdunes. This alliance occurs on well-drained sands of back dunes and interdunes, and is documented from Assateague Island; it is a maritime dwarf-shrubland characterized by Hudsonia tomentosa, a species adapted to sand burial. Hudsonia tomentosa is dominant, occurring as discrete patches that may coalesce into a dense mat on older, more stabilized dunes. A number of other shrubs, such as Morella pensylvanica (= Myrica pensylvanica), Morella cerifera (= Myrica cerifera), Pinus taeda saplings, and Prunus maritima, may occur but are low in abundance and cover. Morella pensylvanica shrubs and Pinus taeda saplings are almost non-existent but can occur as scattered individuals. Herbaceous vegetation is also quite sparse (less than 5% cover) but may include scattered individuals of Panicum amarum var. amarulum, Panicum amarum var. amarum, Solidago sempervirens, Nuttallanthus canadensis, Lechea maritima, Ammophila breviligulata, Pseudognaphalium obtusifolium (= Gnaphalium obtusifolium), Schizachyrium littorale (= Schizachyrium scoparium ssp. littorale), Dichanthelium acuminatum, Oenothera humifusa, Cyperus grayi, Artemisia stelleriana, Chamaesyce polygonifolia, and Diodia teres. Toxicodendron radicans is a common vine. Scattered vines of Smilax rotundifolia and canes of Rubus argutus are occasional. The unstable substrate is influenced by wind-deposited sand and supports no soil development; large patches of sparsely vegetated or unvegetated sand are common.  Accession Code: VB.CC.23053.HUDSONIATOMENTO Plot-observations of this Community Concept: 0
