Type Concept Sentence: No Data Available


Common (Translated Scientific) Name: Bluejoint - Matting Rosette Grass - (Mixed Shrub) Marsh

Colloquial Name: Bluejoint Pondshore Margin

Hierarchy Level:  Association

Type Concept: This pondshore margin community of southern New England and New York generally occurs as a narrow band at the periphery of Coastal Plain pondshore basins, adjacent to the shrub zone or upland forest, if a shrub zone is absent. The substrate is sandy with a shallow organic layer or deeper muck. Characteristic species include Calamagrostis canadensis, Dichanthelium meridionale, Panicum virgatum, Euthamia caroliniana, Viola lanceolata, and Polygala cruciata. Sphagnum cuspidatum can be abundant. Shrubs from the adjacent border may be admixed at variable cover. Shrubs may include Spiraea alba, Clethra alnifolia, Vaccinium corymbosum, Chamaedaphne calyculata, Eubotrys racemosa, or Vaccinium macrocarpon.
