Grassland State
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.
The reference plant community is the Midgrass/Shortgrass with Tallgrass Community. This community is a mixture of short, mid and tallgrasses with considerable forbs and a few shrubs. Sideoats grama and little bluestem with smaller amounts of hairy grama and sand dropseed are also found in this plant community. Good variety of forb species and few woody shrubs are also found on the landscape.
The Shortgrass/Midgrass with Forbs Community is a shortgrass/midgrass dominant plant community with increasing amounts of drought tolerant forbs and woody plants. Yucca invasion is increasing.
Submodel
Mechanism
Due to heavy continuous grazing pressure, brush invasion of yucca and pricklypear, and no fires occurring on the site, the Grassland State will transition to the Shrubland State.
Mechanism
With the implementation of conservation practices including Prescribed Grazing, Prescribed Burning and Brush Management, the Shrubland State can be restored to the Grassland State.
