Name:
Prunus pumila / Andropogon gerardii - Sorghastrum nutans Riverscour Wet Meadow
Reference:
NatureServe Biotics 2019
Description:
These are tall rivershore wet meadows 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 <i>Sorghastrum nutans, Andropogon gerardii, Schizachyrium scoparium</i>, and <i>Panicum virgatum</i>. Characteristic herbs include <i>Helianthemum canadense, Helianthus divaricatus, Asclepias tuberosa</i>, and <i>Lespedeza capitata</i>. <i>Spiraea alba, Rosa virginiana, Quercus ilicifolia, Betula nigra</i>, and <i>Prunus pumila</i> are common shrubs. Other herbaceous associates include <i>Anemone virginiana, Calamagrostis canadensis, Eutrochium maculatum, Solidago rugosa, Solidago nemoralis, Solidago gigantea, Spartina pectinata, Achillea millefolium, Baptisia tinctoria, Asclepias syriaca, Dichanthelium clandestinum, Euthamia graminifolia, Apocynum androsaemifolium, Thelypteris palustris, Lycopus uniflorus, Phalaris arundinacea, Scleria triglomerata</i>, and <i>Symphyotrichum novi-belgii</i>. This association differs from more northerly riverside ice meadows in being dominated by prairie grasses (<i>Andropogon gerardii, Sorghastrum nutans)</i> rather than by <i>Calamagrostis canadensis</i>.
