Reference State
Reference State
Description
The reference state was described by the observation and study of plant communties that have evolved through a long-term interactions of natural disturbances processes, climate, soils and landforms. This reference state is characterized as a native mid and short grassland dominated by alkali sacaton and western wheatgrass.
Submodel
Description
This state is characterized by a dominance of warm season grasses and half shrubs with moderate amounts of native and non-native annuals. Common species in this state include galleta, blue grama, alkali sacaton, rabbitbrush and snakeweed.
Submodel
Mechanism
Establishment of non-native annuals creates an irreversible change in the plant community. Other disturbances such as unmanaged grazing, drought and/or lack of fire all allow for the establishment of native and non-native annuals.
Mechanism
Drought, unmanaged grazing, decline or loss of perennial grass cover, active surface erosion create entrenched channels with headcutting
