Description
The reference state includes the historic climax plant community that evolved with the soils and climate in the area. In this state, the plant communities are dominated by warm and cool season grasses with scattered shrubs and trees. With drought, long term winter dominated moisture patterns, grazing and other disturbances, perennial grasses will decrease and shrubs will increase on the site.
Introduced annuals are present in this common resource area, and very minor amounts of these may occur in the plant communities in this state.
Submodel
Description
The plant communities in this state include the same species and plant community structures as the reference state. Introduced herbaceous species are now part of those plant communities and compete with native species for available moisture. Disturbances over time, such as fire, drought, and uncontrolled grazing, will now have the potential to allow an increase the introduced species on the site.
Submodel
Mechanism
Introduction of non-native annuals species creates an irreversible change in the plant community
Mechanism
Severe drought, unmanaged grazing, severe soil disturbances create areas of bare ground, increase erosion with rills and gullies.
