Name:
Sparganium americanum - (Sparganium erectum ssp. stoloniferum) - Epilobium leptophyllum Seep
Reference:
NatureServe Biotics 2019
Description:
This vegetation occupies marshes and impoundments within small rivers or streams with seasonal flooding, especially in areas currently or formerly flooded by beavers or restricted by natural bedrock or boulder accumulation. Most sites were heavily altered by logging in the late 1800s through the early 1900s, and this disturbance may have altered the distribution, cover, and physiognomy of these wetlands. Soils are variable and may consist of poorly to very poorly drained muck or organic-rich loamy soils of varying texture. <i>Sparganium americanum</i> strongly dominates the dense herb layer at many sites, although at some locations in the Allegheny Mountains and on the Cumberland Plateau, it is replaced by <i>Sparganium erectum ssp. stoloniferum</i>. Common associates vary with geography and include <i>Agrostis hyemalis, Callitriche heterophylla, Carex scoparia, Carex gynandra, Carex lurida, Carex stipata, Eleocharis obtusa, Epilobium coloratum, Epilobium leptophyllum, Galium tinctorium, Glyceria melicaria, Glyceria striata, Hydrocotyle americana, Hypericum mutilum, Impatiens capensis, Juncus effusus, Leersia oryzoides, Ludwigia palustris, Lycopus uniflorus, Poa palustris, Polygonum hydropiperoides, Polygonum sagittatum, Polygonum punctatum, Potamogeton</i> spp., <i>Scirpus cyperinus, Scirpus hattorianus, Scutellaria lateriflora, Solidago rugosa, Sphenopholis pensylvanica</i>, and <i>Symphyotrichum prenanthoides</i>. More locally, <i>Glyceria grandis</i> is an abundant grass. A very sparse shrub layer may be present.
