Salix nigra / Carex torta Temporarily Flooded Shrubland
Reference:
Eastern Ecology Working Group of...
Description:
Willow shrubland of low riverbanks along moderate- to high-energy rivers in the Northeast 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 disturbance gradient between open, herbaceous cobble shores and higher floodplain forests. Salix nigra is often dominant or codominant with other willows or dogwoods. Less frequent shrubs and tree saplings include Salix eriocephala, Salix sericea, Alnus incana, Alnus serrulata, Alnus viridis (infrequent), Cornus amomum, Cornus sericea (= Cornus stolonifera), Spiraea alba var. latifolia, and Platanus occidentalis and Populus deltoides. The herbaceous layer is typically sparse with variable composition including Carex torta, Panicum dichotomiflorum, Dichanthelium clandestinum (= Panicum clandestinum), Echinochloa crus-galli, Phalaris arundinacea, Calamagrostis canadensis, Apocynum cannabinum (= Apocynum sibiricum), Agrostis spp., Solidago gigantea, Solidago rugosa, Eupatorium maculatum, Lysimachia terrestris, Polygonum spp., and Bidens spp. Invasive, exotic species can be problematic in this community, including Polygonum cuspidatum, Tussilago farfara, and Cynanchum louiseae.
