Description
The reference state and the reference (climax) plant community has been determined by study of relict areas or areas protected from excessive disturbances. Trends in plant communities going from unmanaged grazed areas to managed grazed areas, seasonal use pastures and historical accounts have also been used.
This reference state is characterized as a native mixed grassland dominated by western wheatgrass and blue grama.
Submodel
Description
This state is characterized by a decline in the site's ability to benefit from run-in moisture and/or flooding events. Active channels and gullies have changed the sites hydrologic function. Non-native species may occur along channels and drainageways, especially woody species such as tamarisk and Russian olive.
Submodel
Mechanism
Drought, unmanaged grazing, establishment and invasion of native and non-native species.
Unmanaged grazing can be described here as: Season-long grazing providing little rest and recovery for preferred grazed plants during critical growing periods, coupled with high utilization.
