Target ecosystem state
Select a state
Description
This state is typical of wet prairies that are not connected to groundwater (not seepage communities or fens) and that experience full horizon saturation (endosaturation), at least briefly during part of the growing season. Two phases can occur that will transition back and forth depending on fire and flooding frequencies. Longer fire and flooding free intervals will allow woody species to increase such prairie willow, dogwoods and false indigo. When fire and flooding intervals shorten these woody species will decrease or be eliminated.
Submodel
Description
Degraded reference states that have experienced fire suppression and flooding reduction for 20 or more years will transition to this state.
With fire suppression and reduced flooding, woody species such as pin oak and bur oak will begin to increase transitioning this state from a prairie to a Woody Invaded Prairie. Native ground cover will also decrease. Transition from this state to cool season grasslands (State 3) or intensive cropland (State 4) was very common.
Submodel
Description
Conversion of other states to non-native cool season species such as tall fescue, white clover, and red top has been common in this area. Occasionally, these pastures will have scattered bur oaks or pecan.
Transitioning to a Cropland State to help eliminate non-native grassland species and then restoring to a reference state is usually the easiest and most useful method of restoration from this state.
Submodel
Description
This is the dominant state that exists currently with intensive cropping of corn, soybeans, and wheat occurring. A return to the reference state may be difficult and costly, requiring a very long term series of management options.
