Mechanism
Mesquite clearing for either wood harvest or cultivation. Irrigation abandoned, greythorn, other shrubs with shrubby mesquite form a scrubland. Water table intact.
Mechanism
Water-table depleted by groundwater pumping to greater than 60 feet. Mature mesquites die back to a shrubby growth that rainfall can support. No return, if pumping is associated with urban areas or development.
Mechanism
Introduction of a seed source for non native annuals likeLondon rocket, foxtail barley, red brome and rescue brome.
Mechanism
Sedimentation of main stream system will cause water-tables to rise, eventually drowning out mesquite. Water tables are within rooting depth (20 feet) of sacaton. Gullies and stream channels fill with sediment and flooding resumes. Site returns to sacaton potential with PG/NG, see site description R041XC312AZ.
Mechanism
50 to 100 years with no further mesquite harvest or control to go back to mature mesquite trees rooted 50 foot deep.
Mechanism
Sedimentation of main stream system will cause water-tables to rise, eventually drowning out mesquite. Water tables are within rooting depth (20 feet) of sacaton. Gullies and stream channels fill with sediment and flooding resumes. Site returns to sacaton potential with PG/NG, see site description R041XC312AZ.
Mechanism
Cessation of groundwater pumping may allow water tables to rise over time to within 50 feet of the surface. Time depends on depth of depletion and amount of pumping reduced. This will not occur in urban or developing areas.

Unknown, possible herbicide control of exotic annuals.

Mechanism
Gully and stream erosion deepen channels and lower water-table to more than 20 feet from the surface. Sacaton thins out, mesquite increases and slowly forms a mature bosque.
