Name:
Typha latifolia - Ageratina altissima - Juncus spp. Marsh, Wet Meadow & Shrubland Macrogroup
Reference:
NatureServe Biotics 2019
Description:
This largely freshwater wetland macrogroup encompasses shrub swamps, marshes, wet meadows and wet prairies of temperate and boreal eastern North America, north of the southern Atlantic and Gulf coastal plains and east of the Great Plains and Yukon Territory. It is dominated by graminoids (e.g., species of the genera <i>Calamagrostis, Carex, Echinochloa, Glyceria, Juncus, Leersia, Schoenoplectus, Scirpus, Sparganium, Typha, Zizania)</i>, forbs (e.g., species of the genera <i>Bidens, Eupatorium, Lobelia, Polygonum, Rumex, Sagittaria</i>), and shrubs (e.g., species of <i>Alnus, Cornus, Salix, Spiraea, Viburnum</i>) in a widely variable composition and structure. This macrogroup also contains eastern inland saline meadows characterized by <i>Atriplex patula, Juncus gerardii</i>, and others. Freshwater marshes and shrub swamps occur in closed or open basins that are generally flat and shallow and are frequently to nearly always flooded. Water depths during high water periods range from a few centimeters to approximately 1 m. Stands assigned to this macrogroup are associated with lakes, ponds, slow-moving streams, non-forested seepages, and/or impoundments or ditches on mineral soils with or without a well-decomposed muck layer. This vegetation spans a wide range, from southeastern and south-central Canada southwest to the Great Lakes states and provinces, south to the Ozarks in Arkansas and east through the northern regions of the Gulf coast states to the southern Appalachian Mountains in Tennessee. It includes the Appalachian Mountain, Piedmont, and Interior Plateau regions, but not the Atlantic or Gulf coastal plains.
