Target ecosystem state
Select a state
Description
This state contains two community phases historically maintained by frequent fire and herbivory(grazing) with adequate recovery periods. High perennial grass cover and production allows for increased soil moisture retention, vegetative production and overall soil quality.
Submodel
Description
This state consists of one community phase that has been invaded by smooth bromegrass and Kentucky bluegrass. Loss of native warm season species/ functional groups and increased bare soil degrade forage productivity, soil moisture retention, organic matter, soil surface structure, plant vigor, etc.
Submodel
Description
This state contains one plant community dominated by reed canary and creeping foxtail. Although both are native species, they can greatly take away from the forage quality as both are undesirable or not consumed by most species throughout the majority of the year.
Submodel
Description
This state is invaded by woody species, primarily Eastern redcedar, Russian olive, dogwood and American basswood. These woody species are present due to lack of prescribed fire and/or brush management measures. These sites typically have a loss of native warm season grasses, degraded forage productivity and reduced soil quality.

Mechanism
Annual haying, summer grazing, or continuous season long grazing can cause the reference state to transition to the Native/Invaded Grass State.
Mechanism
No fire, encroachment of woody species, and flooding can cause the Reference State to transition to the Invaded Woody State. Flooding will establish habitat conditions for cottonwood generation. Eastern red cedar will establish but will die out when the water table rises or when periods of repeated or prolonged flooding occur.
Mechanism
Prescribed grazing over a long time period will move this plant community back toward the Big Bluestem/Switchgrass/Prairie Cordgrass Plant Community or associated successional plant communities assuming an adequate seed/vegetative source exists. This transition may take greater than 20 years to accomplish.
Rotational haying or haying in rotation with grazing will move this plant community back toward the Big Bluestem/Switchgrass/Prairie Cordgrass Plant Community or associated successional plant communities assuming an adequate seed/vegetative source exists. This transition may take greater than 20 years to accomplish.
Mechanism
Seeding or Encroachment of reed canary grass, as well as continuous season long grazing, can cause the Native/Invaded Grass State to transition to the Reed Canary State.
Mechanism
No fire, as well as encroachment of woody species, can cause the Native/Invaded Grass State to transition to the Invaded Woody State
Mechanism
Prescribed grazing over a long time period will move this plant community back toward the Big Bluestem/Switchgrass/Prairie Cordgrass Plant Community or associated successional plant communities assuming an adequate seed/vegetative source exists. This transition may take greater than 20 years to accomplish.
Rotational haying or haying in rotation with grazing will move this plant community back toward the Big Bluestem/Switchgrass/Prairie Cordgrass Plant Community or associated successional plant communities assuming an adequate seed/vegetative source exists. This transition may take greater than 20 years to accomplish.
Mechanism
No fire or Encroachment will convert this plant community to a Deciduous Trees and/or Eastern redcedar Plant Community.
Mechanism
Mechanical or chemical brush management, prescribed burning or timber harvest combined with prescribed grazing can cause the Invaded Woody State to shift back to the Reference State.
