Description
The overstory is dominated by Rio Grande cottonwood and other native shrubs. The understory is comprised of a sparse mix of native grasses, shrubs and forbs. Occasional flooding is important for establishment and maintenance of cottonwood and willows along the streambanks. Fire is not common on this site due to the moist nature of the soils and vegetation, but may occur in rare events.
Submodel
Description
Cottonwoods and other native shrubs dominate the overstory. Exotic annual grasses are present in the understory but the amount of native perennial grasses remains relatively unchanged.
Submodel
Description
Saltcedar and/or Russian olive dominate or co-dominate the overstory with native trees. Native shrubs and grasses can occur in the understory, but non-native annuals are dominant.

Unmanaged grazing, drought, saltcedar and/or Russian olive and annuals such as cheatgrass and ripgut brome are introduced to the site.
Mechanism
Significant disturbances, unmanaged grazing, severe flood event or fire favors non-native annual grasses and forbs. Saltcedar and/or Russian olive are introduced to the site.
