T1-2 - Drought alone or in conjunction with frequent or severe grazing (continuous, season-long) will reduce the key grass species, and encourage sod-forming grasses and grass-likes, forcing this transition.
T1-3 - Frequent and severe (continuous, season-long) grazing, ground disturbance, and drought will reduce the herbaceous cover, leaving a shrub-dominated community. Remnant grasses persist in the protection of shrub or cactus clumps.
T1-4 - Drought, ground disturbance, frequent or severe Grazing or non-use with seed source present allows the soil surface to be opened and vulnerable to invasive species. Non-use has shown to create a “fluffy” soil scenario in which seeds are readily able to establish, but not necessarily persist.
T2-4 - Soil disturbance with a seed source present is the trigger for this transition.
T3-4 - Drought, Frequent or Severe Grazing, Non-Use, or Ground Disturbance with a seed source present reduces the stability and function of saltbush, allowing invasive species to establish.
R3-5 - Grazing lands mechanical treatment, or rangeland seeding with prescribed grazing will be required inputs to alter the soils and hydrology of this site and allow a desirable plant cover to establish and reduce invasive species (species-dependent.)
R4-5 - Integrated Pest Management, Grazing Lands Mechanical Treatment, or Rangeland Seeding with Prescribed Grazing will be required inputs to alter the soils and hydrology of this site, but allow a desirable plant cover to establish and reduce the invasive species (species-dependent.)
T5-4 - Drought, frequent and severe (continuous, season-long) grazing, ground disturbance, or non-use with seed source present leaves restored or reclaimed sites vulnerable to invasive species.
CP1.1-1.2 - Long-term prescribed grazing allows existing populations to gain vigor and encourages seedlings if seed source is available and climatic conditions are favorable. This site may require mechanical or cultural inputs to allow minor improvements in a foreseeable time frame.
CP1.1-1.3 - Drought alone or in conjunction with frequent or severe grazing will reduce the grass species, specifically Indian ricegrass and bottlebrush squirreltail and encourage bluegrasses, forcing this transition.
CP1.2-1.1 - Prescribed grazing (possibly long-term), allows the sensitive “decreaser” species a chance to recover where remnant populations are still viable.
CP1.2-1.3 - Frequent and severe grazing of cool-season grasses during growing season, and drought removes or reduces bottlebrush squirreltail on these sites, allowing western wheatgrass to increase.

CP4.1-4.2 - Drought, non-use, disturbance, or frequent or severe grazing weakens the herbaceous species on this site, allowing invasive species to increase in dominance.
CP4.2-4.1 - Integrated Pest management with Prescribed Grazing reduces the density of the weed population and allows the native species to increase only with proper deferment and seed bank.
