Submodel
Mechanism
Proximity to seed source, introduction of seeds, lack of fire for long periods of time
Mechanism
Continuous Heavy Grazing (managing for annuals), persistent low perennial grass cover. Reduction of A Horizon, Organic Matter and litter, compaction, persistently reduced infiltration.
Mechanism
Continuous Heavy Grazing, introduction of seed source for non-native perennial grasses, usually from a road or right of way.
Restoration pathway R2A
Mechanism
Herbicide or mechanical means to remove mesquite, other shrubs, succulents. Prescribed Grazing/No Grazing. Implementing brush management (chemical or mechanical) puts site at risk to transition to State 2.
Mechanism
Continuous Heavy Grazing coupled with drought (or fire), low perennial grass cover, reduction of A Horizon, Organic Matter and litter. Compaction and severe trailing leaving terracettes on hillslopes. Severe sheet, rill and gully erosion on steep hillslopes. Persistently reduced infiltration and limited recruitment of grass.

Mechanism
Prescribed Grazing/No Grazing, seeding or planting of natives like sideoats grama. Possible herbicide control of annuals (unknown).
