The reference state includes the Historic Climax Plant Community and was described by the observation and study of plant communties that have evolved through the long-term interactions of natural disturbance processes, climate, soils and landforms. This reference state is characterized as a native mid and short grassland dominated by warm season grasses.
Establishment of non-native annual species creates an irreversible change in the plant community. Unmanaged grazing, drought, decrease of perennial herbaceous ground cover, increase bare ground allow for the invasive of native and non-native annual grasses and forbs.
