Acer saccharinum
The bottomlands and margin areas in the northern hardwood communities are primarily dominated by: red maple ("Acer rubrum"), balsam poplar ("Populus balsamifera"), black ash ("Fraxinus nigra"), eastern cottonwood ("Populus deltoides"), and the silver maple ("Acer saccharinum"). The bottomlands and margin areas of the coniferous forests consist of: red maple, silver maple, white cedar, and balsam poplar. In wet areas throughout the region many sub-canopy species of willow ("Salix" spp.) occur, as does speckled alder ("Alnus rugosa"), which is very common.
