Submodel
Description
Wide channel, with no streamflow and a lowered water table. Active gully and streambank erosion processes. Native annuals occur on riverwash sands in response to rainfall.
Submodel
Description
Cottonwood and willow cover eliminated by flood or fire. Saltcedar rapidly colonizes and achieves up to 80% cover. Understory cover reduced to near zero.
Submodel
Mechanism
Water table is lowered to a depth of greater than 20’ by groundwater pumping. Mature trees die back to a level supported by periodic flooding.
Constraints to recovery
Site cannot recover without elimination of groundwater pumping.
Mechanism
Continuous heavy grazing suppresses cottonwood and willow seedling maturation. Old trees die-out.
Mechanism
Cessation of pumping may permit groundwater level to rise with time.
