Name: Juncus effusus - Lythrum salicaria - Phalaris arundinacea Eastern North American Ruderal Marsh, Wet Meadow & Shrubland Macrogroup
Reference: NatureServe Biotics 2019
Description: This macrogroup includes disturbed marshes and wet meadows in the eastern and southeastern United States and southeastern Canada, which are dominated by native ruderal or exotic species. This macrogroup is composed of herbaceous- or shrub-dominated, temporarily, irregularly, seasonally or semipermanently flooded wetlands. Sites often have a history of significant disturbance such as heavy pasturing, agricultural or urban stormwater runoff, or alteration in hydrologic regimes. Along with the wide range in flooding regimes, there can be a wide variety of dominant species, some of which can form near monocultures. Some common herbaceous dominants include <i>Juncus effusus, Lythrum salicaria, Phalaris arundinacea</i>, exotic <i>Phragmites australis</i> (chloroplast haplotype M), <i>Polygonum cuspidatum, Scirpus cyperinus</i>, and <i>Typha</i> spp. Typical shrubs include <i>Ligustrum sinense, Lonicera maackii</i>, and in southern coastal areas <i>Tamarix</i> spp.
