Mechanism
Non-native bunchgrass seed source (wind-blown or mechanical transport) paired with native perennial grass community disturbance such as fire or unmanaged grazing.
Mechanism
Long-term unmanaged grazing with or without drought/fire interaction opens perennial grass canopy allowing shrubs to outcompete resources. Juniper, mimosa and other shrubs are likely to increase as well as yucca-like succulents. Remnant native perennial grasses cannot re-colonize areas with shrub competition.
Mechanism
No restoration pathway known at this time. Perhaps future development of herbicide or biological treatment to remove perennial exotics will occur.

Mechanism
Long-term unmanaged grazing with or without drought/fire interaction opens perennial grass canopy allowing shrubs to outcompete perennial grasses for resources. Juniper, mimosa and other shrubs are likely to increase as well as yucca-like succulents. Remnant native perennial grasses cannot re-colonize areas with shrub competition.
Mechanism
Brush management, native species seeding (as needed) supported by managed grazing. Shrub control maintained with herbicide and/or prescribed burning.

Mechanism
Long-term unmanaged grazing affects soil site stability and hydrologic functioning. Animal trailing and soil surface compaction compound the effect of plant community changes (increased shrub/decreased perennial grass community) to increase surface water run-off rather than infiltration. Over time (50-100+ years) the mollic A horizon can be lost leaving the site with a reduction in potential productivity.
