Name: Equisetum fluviatile Herbaceous Vegetation Reference: Western Ecology Working Group of... Description: This is an emergent wetland community occurring on seasonally to permanently flooded edges of lakes and ponds, along tidally influenced plains of larger rivers, calm backwater areas of rivers and streams, and in watered abandoned channels. It is presently documented from scattered locations of the Pacific Northwest, from coastal Washington to the interior regions of western Montana and north into the Boreal Plains of Alberta. It occurs from sea level to 1340 m (0-4390 feet) in elevation. Water depths range from below the soil surface to 0.5 m (1.5 feet) deep. Soils are fine-textured silts, clays and muck. Mineral soils often have layers of organic accumulation. Along the Columbia River Gorge, stands occur on river and slough channels on sand and silt and are flooded by freshwater during most high tides. Inland, stands occur in shallow water and wet ground at the edges of slow-moving meander curves in rivers and on the margins of lakes and ponds, stock ponds and reservoirs. Stands are characterized by emergent <i>Equisetum fluviatile</i> with 30-100% cover but tend to be species-poor. Other species present can include <i>Glyceria grandis, Alopecurus aequalis, Carex</i> spp., <i>Eleocharis palustris, Typha</i> spp., and <i>Scirpus</i> and/or <i>Schoenoplectus</i> spp. Stands at lower elevations (Columbia River Surge Plain) had higher species diversity (n=18 for all sampled stands combined) than those at higher elevations (n=3 eastern Washington and Montana).  Accession Code: VB.CC.34172.CEGL002746 Plot-observations of this Community Concept: 0
