Name: Equisetum arvense - Equisetum hyemale - Equisetum variegatum Wet Meadow Alliance
Reference: NatureServe Biotics 2019
Description: This alliance is an herbaceous wetland characterized by a moderately dense to dense herbaceous layer of <i>Equisetum arvense, Equisetum hyemale</i>, or <i>Equisetum variegatum</i>. Other obligate or facultative wetland plants may be present in low cover, but the dominance of <i>Equisetum</i> spp. is diagnostic of this type. Introduced graminoids, such as the perennial <i>Poa pratensis</i> or the annual <i>Bromus diandrus</i>, are known to codominate some stands. Sites include streambanks, wet meadows and ditches. Substrates are generally thin organic over alluvium. This community is typically flooded much of the growing season. The water table is high even when surface water is absent. This wetland alliance occurs in Oregon, Washington, California and British Columbia, Canada.
