Description
This is the reference or diagnostic community for the site. The description is based on early range site descriptions, clipping data, professional consensus of experienced range specialists, and analysis of field work.
Submodel
Mechanism
With heavy continuous grazing pressure, brush invasion of tamarix species, and no fires, the Tallgrass Dominant Community will transition into the Midgrass Dominant Community.
Mechanism
With the implementation of conservation practices such as Prescribed Grazing (with periodic rests during the growing season of perennial warm-season grasses), Brush Management of Tamarix and baccharis species, and Prescribed Burning, the Midgrass Grassland State can be restored back to the Tallgrass Grassland State.

Mechanism
With heavy continuous grazing, brush invasion of Tamarix and baccharis species, no fires, and no brush management, the Midgrass Dominant Community will transition into the Shortgrass/Annuals Community.
Mechanism
With Prescribed Grazing over a one to four year period, Pest Management, Brush Management (Individual Plant Treatments), the Shortgrass Grassland State can be restored to the Midgrass Grassland State.
