Name:
Populus deltoides - Salix nigra - Acer saccharinum Floodplain Forest
Reference:
NatureServe Biotics 2019
Description:
This cottonwood - black willow - silver maple forest is characteristic of the fronts and banks of most major rivers and large streams throughout the Central Forest Region, extending into the northern forest particularly within the Mississippi, Ohio, and Missouri river systems. It develops on bare, moist soil on recently formed sand bars, front-land ridges, and well-drained flats, along with <i>Salix interior, Eragrostis hypnoides, Leptochloa panicea ssp. brachiata, Lipocarpha micrantha, Rumex maritimus, Potentilla paradoxa</i>, and <i>Bidens</i> spp. This natural community can also be found well-drained ridges in the first bottoms. Soils are formed in alluvium, are deep, medium-textured, and with adequate or excessive moisture available for vegetation during the growing season. The tree canopy is tall (to 30 m) and dominated by <i>Populus deltoides, Salix nigra</i>, and <i>Acer saccharinum</i>, although <i>Fraxinus pennsylvanica, Acer negundo, Platanus occidentalis</i>, and <i>Ulmus americana</i> are also commonly encountered. Tree diversity is limited due to the dynamics of flooding and resultant deposition and scouring of sediments. In earlier successional stages, the subcanopy can be strongly dominated by <i>Salix nigra</i>. The shrub layer is conspicuously absent in many parts of the range. Herbaceous growth can be thick and lush but is often patchy and sparse due to frequent inundation. Species most often encountered in the ground layer include <i>Carex</i> spp., <i>Leersia oryzoides, Bidens</i> spp., and Asteraceae spp.
