Submodel
Description
This plant community is predominately midgrasses with some little bluestem. The dominant grasses are sideoats grama, blue grama, buffalograss, silver bluestem and some threeawn. This plant community is the result of long term heavy continuous grazing. There is usually a remnant of little bluestem and other grasses that will respond to prescribed grazing. The time needed to return to a little bluestem dominated community can be 5 to 10 years depending on rainfall, stocking rate, and other factors.
Mechanism
Without fire or other brush management, the site may be invade by woody species. Once these species begin to dominate the ecological functions on the site, the site will transition to the Shrubland state(2).
Mechanism
Through tillage and planting for crop production or introduced pasture, this site will be transitioned to the converted state(3).
