Description
The historical reference community for this ecological site was an old growth floodplain forest with multiple species including oaks, hickory, sycamore, elm, walnut, maple, ash, Periodic natural disturbances included flooding, wind damage or ice storms; however, catastrophic disturbances were rare and these communities generally evolved into old-growth, dense forests with a high level of canopy cover and diversity.
Dominant plant species
oak (Quercus), tree
American sycamore (Platanus occidentalis), tree
hybrid hickory (Carya), tree
American elm (Ulmus americana), tree
pawpaw (Asimina triloba), shrub
dogwood (Cornus), shrub
northern spicebush (Lindera benzoin), shrub
sedge (Carex), grass
Virginia wildrye (Elymus virginicus), grass
Canadian clearweed (Pilea pumila), grass

Description
This community is characterized by the removal of the higher value tree species, primarily oak species, or other disturbances that remove the oaks, hickories and/or black walnuts. Oak regeneration is often limited without timber stand improvement inputs. Disturbance often introduces non-native understory species which, if not controlled, will overtake the site and impede oak reproduction. Fast growing, shade tolerant species often gain in prominence within the community structure.
Dominant plant species
maple (Acer), tree
ash (Fraxinus), tree
tuliptree (Liriodendron), tree
honeysuckle (Lonicera), shrub
autumn olive (Elaeagnus umbellata), shrub
Nepalese browntop (Microstegium vimineum), grass
garlic mustard (Alliaria petiolata), grass
Submodel
Description
This state is characterized by the conversion of the site to agricultural use. Most common practice is a corn and soybean rotation of various types. A small portion of the historic acres are used for forage and pasture. Species depend on landowners management objectives.
Dominant plant species
tall fescue (Schedonorus arundinaceus), grass
brome (Bromus), grass
Kentucky bluegrass (Poa pratensis), grass
red clover (Trifolium pratense), grass
white clover (Trifolium repens), grass
corn (Zea mays), grass
soybean (Glycine max), grass
Submodel
Mechanism
Substantial disturbance such as clearing or selective harvest. Little or no post-harvest timber stand management. No control of non-native species.
Mechanism
Clearing of mature high-quality forest for conversion to agricultural production. This transition is for sites with lower slopes only. Landowners should be aware of any potential wetland issues on or near these sites.
Restoration pathway R2A
Planting; brush control; weed control; long-term timber stand improvement inputs
Mechanism
Restoration of site would include long-term timber stand improvement inputs including planting of desired tree species and continual brush and weed control.
Mechanism
Transition from forest to agricultural state. Activities would be determined by the landowner’s production objectives.
Mechanism
Cropland or pastureland that is abandoned will slowly, but naturally, transition to a mixed deciduous woodland usually dominated by low-value trees such as maple, ash, elm, etc. Often non-native species make up all or a portion of the shrub and understory layers.
