Name:
Equisetum fluviatile - Equisetum x ferrissii Marsh Alliance
Reference:
NatureServe Biotics 2019
Description:
This herbaceous alliance of shallow emergent marshes is dominated by <i>Equisetum fluviatile, Equisetum laevigatum</i>, and/or <i>Equisetum x ferrissii</i> as the most abundant species, which can form monotypic stands. In mixed stands, the graminoids <i>Agrostis gigantea, Alopecurus aequalis, Carex aquatilis, Carex rostrata, Carex utriculata, Eleocharis palustris, Glyceria grandis, Juncus arcticus ssp. littoralis, Muhlenbergia asperifolia, Scirpus</i> and/or <i>Schoenoplectus</i> spp., and the forbs <i>Bidens cernua, Epilobium leptophyllum, Galium trifidum, Mentha arvensis</i>, and <i>Scutellaria galericulata</i> may be present. Ponds are shallow (<1 m in depth), over mineral soils, usually sand or silt, located along wave-washed shores or lakes or stream channels, including the tidal reaches of the Columbia River. The water is nearly fresh with a very low salt content. In Montana, British Columbia and Alberta, stands occur in still water and on wet ground along the margins of ponds or protected bays in lakes and backwater areas of streams.
