Name:
Western North American Ruderal Marsh, Wet Meadow & Shrubland Macrogroup
Reference:
NatureServe Biotics 2019
Description:
This macrogroup contains disturbed natural habitats such as wet meadows, emergent marshes, coastal backwater dunes, and sloughs as well as waste areas that were once wetlands and are now dominated by non-native species. Dominant non-native species include <i>Agrostis gigantea, Agrostis stolonifera, Alopecurus pratensis, Arundo donax, Cirsium arvense, Conyza canadensis, Schedonorus arundinaceus, Lactuca serriola, Phalaris arundinacea, Phragmites australis, Poa palustris, Poa pratensis</i>, and <i>Sonchus</i> spp. Native species may be present but are so low in abundance that they are insufficient to identify the native macrogroup or lower units. This macrogroup occurs from sea level up to the subalpine throughout the western U.S. Due to disturbance, soils may be compacted, missing upper horizons, or unnaturally enriched or depleted. Disturbance can be from activities such as severe continuous heavy grazing, abandoned building sites, industry, and road beds, areas that have been logged, or chained and cleared that occur where wetlands once stood.
