Description
The Grassland State is composed of mid and short warm-season grasses with a few forbs and few woody shrubs. Dominant grass species are blue grama and sideoats grama with small amount of mesquite and a few perennial forb species.
Submodel
Description
The Shrub/Shortgrass Community (2.1) is composed of warm-season shortgrasses with mesquite. This community is also dominated by increasing woody canopy of shrubs such as mesquite and redberry juniper.
Submodel
Description
The Degraded Grassland State is composed of degraded annuals and shortgrasses. Shortgrasses will continue to dominate the site with large components of annual grasses and forbs. There are also shrubs and half-shrubs present in this plant community.
Submodel
Mechanism
With heavy continuous grazing pressure, no fires, and brush invasion of mesquite and juniper, the Grassland State will transition into the Shrubland State.
Mechanism
With the use of various conservation practices such as Prescribed Grazing, Brush Management, and Prescribed Burning, the Shrubland State may be able to be restored back to the Grassland State.
