Target ecosystem state
Select a state
Description
This state is native tall grass prairie dominated by little bluestem, big bluestem and forbs, but also a substantial component of wet tolerant sedges. This state occurs on level to gently sloping soils that have a seasonal high water table that is perched above the abrupt textural change or clayey subsoil during the spring months in most years. This condition influences the species composition and site productivity. Two phases can occur that will transition back and forth depending on fire frequencies. Longer fire free intervals will allow woody species to increase such as gray dogwood and eastern redcedar. When fire intervals shorten these woody species will decrease.
This state is extremely rare. Nearly all remaining sites have been converted to cool season grassland, cropland, or have been degraded through uncontrolled domestic livestock grazing.
Submodel
Description
Degraded reference states that have experienced fire suppression for 20 or more years will transition to this state. With fire suppression, woody species such as pin oak and eastern redcedar will begin to dominate transitioning this state from a prairie to a Woody Invaded Savanna. Native ground cover will also decrease and invasive species such as tall fescue may begin to dominate.
Submodel
Description
Conversion of other states to non-native cool season species such as tall fescue and red clover has been common. Occasionally, these pastures will have scattered oak. Long term uncontrolled grazing can cause significant soil erosion and compaction. A return to the reference state may be impossible, requiring a very long term series of management options.
Submodel
Description
This is the dominant state that exists currently with intensive cropping of corn, soybeans, and wheat occurring. Some conversion to non-native cool season grassland occurs for a limited period of time before transitioning back to cropland. Limited acres are sometimes converted to native warm season grassland.
Submodel
Description
Conversion from the Cool Season Grassland (State 3) or the Cropland (State 4) to this state is increasing due to renewed interest in warm season grasses as a supplement to cool season grazing systems or as a native restoration activity. This state is the most easily transformable state back to a reference state. Substantial restoration time and management inputs will be needed.
Submodel
Mechanism
Fire suppression activities for greater than 20 years and woody invasion will result in a transition to community phase 2.1.
Mechanism
Destroying the prairie sod with tillage, adding a cool season grass/legume vegetative seeding and grassland management will result in a transition to community phase 3.1.
Mechanism
Removing the prairie sod with tillage and adding a conservation cropping system and surface drainage will result in a transition to community phase 4.1.
Mechanism
Transition activities include prescribed grazing; prescribed fire
Mechanism
This state can be restored to a reference state with woody removal, brush management, planting additional native grass and forb species (if needed) and initiating a prescribed fire regime (every 1 to 3 years). Limited controlled grazing may also be needed.
Mechanism
Woody removal, brush control, removing the prairie sod with tillage seeding cool season grass and legume species and incorporating grassland management will result in a transition to community phase 3.1.
Mechanism
Woody removal, brush control, removing the prairie sod with tillage and incorporating conservation cropping system and surface drainage will result in a transition to community phase 4.1.
Mechanism
Removing the cool season sod with tillage and adding a conservation cropping system and surface drainage will result in a transition to community phase 4.1.
Mechanism
Killing the existing cool season sod, reseeding to native warm season grasses and adding prescribed fire will result in a transition to community phase 5.1.
Mechanism
A seeding of cool season grasses and legumes and grassland management will result in a transition to community 3.1.
Mechanism
A seeding of native warm season grasses and grassland management will result in a transition to community 3.1. Prescribed fire is added in many cases.
Mechanism
This state can be restored to a reference state by planting additional native grass and forb species and initiating or maintaining a prescribe fire regime (every 1 to 3 years). Limited
controlled grazing may also be needed.
