Name: Cephalanthus occidentalis / Carex spp. Northern Shrubland Reference: Midwestern Ecology Working Group... Description: This buttonbush swamp shrubland community occurs throughout glaciated regions of the midwestern and northeastern United States and adjacent Canada. Stands occupy shallow water depressions, oxbow ponds, and backwater sloughs of stream and river floodplains. Inundation is usually continuous throughout the year, but these sites can become dry in mid or late summer or during periods of prolonged drought. Soils are deep (>100 cm) consisting of peat or muck over alluvial parent material. The shrub layer can vary from very open to closed (20-80%). Cephalanthus occidentalis typically comprises nearly 90% of the shrub layer in waters 1-2 m deep. Other shrubs commonly encountered include Cornus sericea, Decodon verticillatus, Ilex verticillata, Rosa palustris, and Salix nigra. The herbaceous layer can be very sparse, due to flooding. Rooted or floating aquatics may dominate, including Lemna minor and Nuphar lutea ssp. advena. Herbs present on the shallow margins include Bidens frondosa, Boehmeria cylindrica, Carex lacustris, Glyceria striata, and others. A scattered tree canopy may occur, including the following species: Acer rubrum, Acer saccharinum, Fraxinus nigra, Fraxinus pennsylvanica, and Ulmus americana. Diagnostic features include the dominance by Cephalanthus occidentalis in glaciated regions and, typically, the presence of standing water.  Accession Code: VB.CC.22844.CEPHALANTHUSOCC Plot-observations of this Community Concept: 0
