Description
Original pre-settlement plant community with cool and warm season grasses dominating with scattered four-wing saltbush and other native shrubs and forbs
Submodel
Description
This plant communty is a shrubland with sparse perennial grasses and an increase in native and non-native annuals.
Submodel
Description
This site is dominated by an overstory of tamarisk with an understory of primarily annuals and few native shrubs and perennial grasses. Some sites may have a understory invaded by camelthorn or Russian knapweed.
Submodel
Mechanism
Increase in invasives native shrubs and annuals due to various factors including decline of perennial cool and warm season grasses from year-round grazing and decreased site stability; changes also be due to decrease in flooding frequency and intensity due to drought and/or water diversion and channel changes. This reduces the benefit of overland flow that promotes productive grasslands.
Mechanism
Managed grazing/No grazing, woody species control, invasive weed control, range seeding.
Mechanism
Unmanaged grazing, persistent drought, increase in invasive woody species, channelized flows accelerate channel scour, gully erosion and create deep channels that promote the establishment of invasive woody species thru seed sources and frequent flooding.
