Moderate

A range of forested wetlands found in depressions and low-lying areas, along waterways, and in floodplains. These forests are heavily influenced by local hydrology, with plant communities that reflect the occurrence of seasonal flooding, erosion, groundwater seepage, or other local dynamics. Better-drained soils may support a variety of hardwood species suited to local conditions, often dominated by pin oak, swamp white oak, shagbark hickory, and sweetgum.

Diverse forested wetlands are found in depressions and low-lying areas, along waterways, and in floodplains. Dominant species may include ash, red or silver maple, swamp white oak, sycamore, American elm, and river birch.

Forests are composed largely of sugar and red maple. Eastern hemlock, yellow birch, basswood, red oak, and black cherry are common associates, found in varying amounts based upon site conditions.

Stands are generally dominated by jack pine, with some composed primarily of mixed pine species or occasionally Scotch pine. Oak species may be co-dominant in some stands.

"This forest ecosystem is primarily found in the glaciated portion of Ohio, where varying microtopography and moisture regimes create mixed communities of upland and lowland species. Common species include sugar maple, American beech, northern red oak, American basswood, eastern hemlock, black cherry, tulip tree, red maple, white ash, and eastern hophornbeam."

This forest is mostly limited to West Virginia and consists of hardwood or hemlock-hardwoods in sheltered topographic positions, often on concave slopes or in areas with high precipitation. Common species include sugar maple, white ash, American basswood, yellow buckeye, tulip tree, red maple, eastern hemlock, cucumbertree, American beech, sweet birch, northern red oak, black cherry, mountain magnolia, and black oak.

Mesic bottomland forests are characterized by short, infrequent floods and mesic soil conditions. Dominant species include white and bur oak, sugar maple, American and slippery elm, bitternut hickory, black walnut, pecan, sycamore, hackberry, river birch, sweetgum, and beech.

Lowland and riparian hardwoods occur on alluvial soils or impermeable clay layers that are seasonally or annually inundated or saturated. Common tree species include red maple, northern white-cedar, silver maple, black ash, and green ash.

Northern hardwoods occur on mesic soils that provide consistent moisture and nutrients. Gap-sized disturbances are common, but stand-replacing events are very infrequent. Common species include sugar maple, red maple, American beech, American basswood, and eastern hemlock.
