CEGL005148 Equisetum (arvense, variegatum) Wet Meadow
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: (Field Horsetail, Variegated Scouring-rush) Wet Meadow
Colloquial Name: Horsetail Wet Meadow
Hierarchy Level: Association
Type Concept: This wetland association is reported from Utah and Ontario, Canada, but its distribution is much broader. If its range is similar to the ranges of dominant and diagnostic species, then it likely occurs throughout much of northern and western North America. Sites include streambanks, wet meadows and ditches. Substrates are generally organic alluvium. This community is typically flooded much of the growing season. The water table is high even when surface water is gone. The vegetation is characterized by the moderately dense to dense herbaceous layer that is dominated or codominated by Equisetum arvense or Equisetum variegatum. Other wetland and facultative wetland plants may be present in low cover, but the dominance of Equisetum spp. is diagnostic of this type. Introduced graminoids such as the perennial Poa pratensis or the annual Bromus diandrus are known to codominate some stands.
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: Type was established to accommodate southern Ontario vegetation types listed in Lee et al. (1998). This association may have been largely overlooked because of its small scale or included with other vegetation types.

Floristics: This wetland association is characterized by the moderately dense to dense herbaceous layer that is dominated or codominated by Equisetum arvense or Equisetum variegatum. Other wetland and facultative wetland plants may be present in low cover, but the dominance or codominance of Equisetum spp. is diagnostic of this type. Introduced graminoids such as the perennial Poa pratensis or the annual Bromus diandrus are known to codominate some stands.
