A2642 Argentina anserina Wet Meadow Alliance
Type Concept Sentence: Low forb community dominated by Argentina anserina that occurs on deep soils on well- and poorly drained areas, such as mudflats or meadows of the Rocky Mountains, Intermountain West basins, and eastern Cascades.
Common (Translated Scientific) Name: Silverweed Cinquefoil Wet Meadow Alliance
Colloquial Name: Silverweed Cinquefoil Wet Meadow
Hierarchy Level: Alliance
Type Concept: This low forb alliance is dominated by Argentina anserina. Additional forbs include Monolepis nuttalliana, Oxytropis deflexa, Potentilla rivalis, and Veronica peregrina. Graminoids present may include Juncus bufonius, Panicum capillare, and Poa secunda. This alliance occurs in the Rocky Mountains, Intermountain West basins, and eastern Cascades on deep soils on well- and poorly drained areas, such as mudflats or meadows with a lot of burrowing small mammal activity.
Diagnostic Characteristics: Meadows and mudflats dominated by Argentina anserina.
