CEGL006065 Salix nigra - Salix spp. / Carex torta - Apocynum cannabinum Wet Shrubland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Salix nigra - Salix spp. / Carex torta - Apocynum cannabinum Wet Shrubland
Colloquial Name: Northeast Willow Riverbar Shrubland
Hierarchy Level: Association
Type Concept: This community is a willow shrubland of low riverbanks along moderate- to high-energy rivers in the northeastern U.S. and High Allegheny Plateau. It occurs on cobble substrates with sand and gravel in areas that are flooded only during high-water events, but receive winter ice-scour. It occupies an intermediate position along a disturbance gradient between open, herbaceous cobble shores and higher floodplain forests. Salix nigra is often dominant or codominant with other willows or dogwoods forming a dense shrub layer. Less frequent shrubs and tree saplings include Salix eriocephala, Salix lucida, Salix sericea, Alnus incana, Alnus serrulata, Cornus amomum, Cornus sericea, Spiraea alba var. latifolia, Platanus occidentalis, Acer rubrum, Acer saccharinum, and Populus deltoides. The herbaceous layer is often sparse but variable in cover and composition, including Carex torta, Panicum dichotomiflorum, Panicum virgatum, Dichanthelium clandestinum, Echinochloa crus-galli, Elymus virginicus, Justicia americana, Boehmeria cylindrica, Polygonum amphibium, Phalaris arundinacea, Calamagrostis canadensis, Apocynum cannabinum, Agrostis spp., Solidago gigantea, Solidago rugosa, Eupatorium maculatum, Rorippa islandica, Lysimachia terrestris, Polygonum spp., and Bidens spp. Invasive, exotic species can be problematic in this community, including Polygonum cuspidatum, Lythrum salicaria, Tussilago farfara, and Cynanchum louiseae.
