Name: Andropogon gerardii - Campanula rotundifolia - Solidago simplex Herbaceous Vegetation Reference: Eastern Ecology Working Group of... Description: This riverside rock outcrop community of New England and New York occurs on open flood scoured bedrock exposures of major rivers, typically along river-narrows. Emergent seepage is absent. Typically a gradient from dry acidic conditions higher on the bank to moist, fairly enriched conditions lower down may exist at any one site. This community is prone to flooding in the upper regions and deposition in the topographically lower areas. It is also prone to severe drought periods that may stress or kill some vegetation. Within the community the species are distributed patchily probably due to microsite conditions. The amount of variability in species composition has not been measured but the sites included show substantial variation from site to site and from year to year. Characteristic species include Andropogon gerardii, Schizachyrium scoparium, Campanula rotundifolia, Solidago simplex, Toxicodendron radicans, Ionactis linariifolius, Packera paupercula (= Senecio pauperculus), Astragalus robbinsii var. jesupii (in limited areas along the upper Connecticut River), and Prunus pumila. This association is more temperate than the related Campanula rotundifolia - Packera paupercula - (Aquilegia canadensis) Sparse Vegetation (CEGL006532), which occurs on near-boreal rivers and lacks prairie elements such as Andropogon gerardii.  Accession Code: VB.CC.28012.ANDROPOGONGERAR Plot-observations of this Community Concept: 0
