Name: A.201 Reference: EcoArt 2002 Description: This alliance, found in the Great Lakes states and northeastern United States, is characterized by wetland forests strongly dominated by ~Tsuga canadensis$. Canopy associates include ~Chamaecyparis thyoides$ (in the eastern portion of this alliance's range), ~Acer rubrum, Acer saccharum, Nyssa sylvatica$ (in the east), ~Pinus strobus, Betula alleghaniensis$, and ~Thuja occidentalis$ (in the center and west). The forest floor generally receives little light due to the dense canopy and thus has poorly developed herb and shrub layers. Shrubs occur in low abundance and may include ~Corylus cornuta$ (in the west), ~Vaccinium corymbosum, Lindera benzoin$ (in the east and center), and ~Ilex verticillata$. ~Osmunda$ spp. and ~Viola$ spp. are often found in these communities across their range while ~Onoclea sensibilis$ is common in the east and in the west ~Maianthemum canadense, Cornus canadensis$, and ~Coptis trifolia$ can usually be found. ^Soils of this alliance vary from saturated muck to imperfectly drained mineral soils and are often acidic. Communities in this alliance occur in upland valleys created by bedrock depressions, on lower slopes, or adjacent to streams and lakes. In most cases they are transitional between wetland and upland communities. Microtopography is sometimes characterized by mounds and depressions caused by uprooted trees.  Accession Code: VB.CC.1710.A201 Plot-observations of this Community Concept: 0
