Target ecosystem state
Select a state
Description
This state is tall grass prairie dominated by big bluestem, eastern gamagrass and a wide variety of prairie forbs. This state occurs on level to gently sloping soils. Bur oak, pin oak, shellbark hickory, American elm, American hazelnut, prairie willow and American plum occurred as scattered individuals across the landscape. Two phases occurred that will transition back and forth depending on fire frequencies.
Submodel
Description
Degraded reference states that have experienced fire suppression and woody invasion for 20 or more years will transition to this state. With fire suppression, woody species such as bur oak, pin oak, and shellbark hickory will begin to increase transitioning this state from a prairie to an open savanna. Native herbaceous ground cover will also decrease. This state is extinct.
Submodel
Description
Conversion of other states to non-native cool season species such as tall fescue and red clover has been common in this area. Occasionally, these pastures may have scattered bur oaks. Long term uncontrolled grazing and a lack of grassland management can cause significant soil erosion and compaction and increases in less productive species such as Kentucky bluegrass and weedy forbs such as ironweed.
Submodel
Description
This is the dominant State that exists currently with intensive cropping of corn and soybeans occurring. Some conversion to cool season hayland may occur for a limited period of time before transitioning back to cropland. Limited acres are sometimes converted to native warm season grassland through federal set-aside programs.
