Description
The Mid/Tallgrass Dominant Community is a balanced mixture of tall, mid and a few short grasses, a variety of perennial forbs, and scattered low growing short woody shrubs. Little bluestem and sideoats grama are the dominant species. There are short shrubs such as feather dalea and catclaw mimosa. Common forbs are dotted gayfeather, plains actinea, plains zinnia and baby white aster.

Description
Midgrasses dominate the site along with some low growing shrubs. Some increase in perennial threeawn. Sideoats grama and blue grama are still the major grasses. Some increase in perennial forbs.
Submodel
Description
The Forb/Pricklypear Dominant Community is composed of shortgrasses, annual forbs, short shrubs, and pricklypear. There is also an increase in bare ground. The annual production potential is lower too.
Submodel
Mechanism
With heavy continuous grazing and no fires, the Midgrass/Tallgrass State will transition into the Midgrass/Shortgrass State.
Mechanism
With Prescribed Grazing and Prescribed Burning conservation practices, the Midgrass/Shortgrass State can revert back to the Midgrass/Tallgrass State.
