Description: This alliance is found throughout the northern states of the United States, excluding the Great Plains states. It is a wide-ranging alliance with much variability in species composition and habitat. Stands of this alliance have a dense graminoid cover, generally over 1 m tall, with either a flat or tussocky microtopography. Tall shrubs may occupy as much as 25% cover. ~Calamagrostis canadensis$ is the characteristic dominant but can be associated with ~Phalaris arundinacea$ or a variety of Carices. Other associates include, in the Northeast, shrubs such as ~Viburnum nudum, Alnus incana$, or ~Alnus serrulata, Viburnum dentatum, Spiraea alba$, and graminoids such as ~Agrostis gigantea (= Agrostis alba)$. In the Midwest, typical associates include several Carices, such as ~Carex stricta, Carex rostrata$, or ~Carex lacustris$, and occasionally ~Poa palustris$ or ~Glyceria grandis$ (Harris et al. 1996). The ground layer can be a heavy mat of grass stems and leaves, with patches of bare soil present in wetter locations. ^The habitat of this alliance is typically mineral soil or well-decomposed peat, usually held together by a dense root mat. Stands are found in floodplains of small streams, beaver meadows, and lakeshores. The hydrology is typically seasonally flooded (Harris et al. 1996). In the southern Appalachians of Tennessee and Virginia, this vegetation occurs in depression meadows and occasionally in beaver ponds.
