Name: Andropogon gerardii - Sorghastrum nutans Herbaceous Vegetation Reference: Eastern Ecology Working Group of... Description: These are tall alluvial grasslands in the temperate region of the northeastern United States. They are found on sandy point bars and linear deposits along semi-stable rivershores subject to periodic flooding. Ice build-up during the winter can scour the rivershore in spring, limiting woody growth. The substrate is cobble, gravel or coarse sediment with interstices of alluvial sand and silt. Bare cobble is exposed in some areas. Herbaceous plants dominate, and may form a dense cover; scattered shrubs may grow among them, but are generally kept short by the annual flooding. Bryophytes are absent or at most sparse. The dominant plants are tall grasses such as Sorghastrum nutans, Andropogon gerardii, Schizachyrium scoparium, and Panicum virgatum. Characteristic herbs include Helianthemum canadense, Helianthus divaricatus, Asclepias tuberosa, and Lespedeza capitata. Spiraea alba, Rosa virginiana, and Prunus pumila are common shrubs. Other herbaceous associates include Anemone virginiana, Calamagrostis canadensis, Eupatorium maculatum, Lycopus uniflorus, Phalaris arundinacea, Scleria triglomerata, and Symphyotrichum novi-belgii. This association differs from more northerly riverside ice meadows in being dominated by prairie grasses (Andropogon gerardii, Sorghastrum nutans) rather than by Calamagrostis canadensis.  Accession Code: VB.CC.20110.ANDROPOGONGERAR Plot-observations of this Community Concept: 0
