Upland forests on heavier soils (clay and silt loams) are dominated by northern hardwoods, such as sugar maple, basswood, white ash and red oak. Shagbark hickory, white oak and bur oak are more common in the southern townships. Helmock occurs in the northern townships. Upland forests on sandy soils consist of red oak, red maple, aspen, white pine and red pine. In swamps black ash, green ash, elm, soft maple, swamp white oak, white cedar and tamarack are common. In riparian areas silver maple, green ash, swamp white oak, elm and cottonwood are common. Most of the upland sites are cropped, therefore the majority of forests in the county are swamps and riparian forests.
