Description
sideoats grama, black grama, little bluestem, New Mexico feathergrass, ricegrass, Arizona fescue, muhly, sumac, and mountain mahogany.
Resilience management
This site is poorly suited for continuous grazing or continued grazing during the growing season and responds best to a system of grazing that rotates the season of use. If the slope is steep enough to limit access, stocking rate should be adjusted. This site does not lend itself to mechanical brush management. Goats could be used as an alternative to maintain a healthy balance within the plant community.
Submodel
Description
As this site deteriorates there is a decrease in the amount of sideoats grama, black grama, little bluestem, New Mexico feathergrass, ricegrass, Arizona fescue, muhly, sumac, and mountainmahogany. There is a corresponding increase in blue grama, pinyon, juniper, oak, algerita and bare ground.
Characteristics and indicators
As deterioration continues, the site will be dominated by pinyon, juniper, algerita, bare ground, and low-vigor sod-type blue grama. In this site erosion can be severe and it is extremely difficult to bring about restoration.
Mechanism
Legacy Statement:
"Restoration pathway resulting from the implementation of prescribed grazing."
It should be noted that prescribed grazing alone may not be sufficient to reduce woody species to levels seen in State 1. Brush control may also be required.
