Description
This state is the result of invasion and dominance of exotic cool-season grasses (e.g., Kentucky bluegrass, crested wheatgrass and smooth brome). This state is characterized by exotic cool-season grasses and an increasing thatch layer that, if invaded with Kentucky bluegrass, effectively blocks introduction of other plants into the system. Once the state is well established, single disturbance events such as high-intensity fires or severe grazing, will not result in more than a very short-term reduction of exotic cool-season grasses. These events may reduce the dominance of the exotic cool-season grasses, but due to the resilience of the exotic there is no opportunity for the native species to establish and dominate before the exotics rebound and again dominate the system.

Description
This state is the result of severe soil disturbance such as cropping, recreational activity, or concentrated livestock activity for a prolonged time period. Following cessation of disturbances, the resulting plant community is dominated by early pioneer annual and perennial plant species. The composition and production of this state is highly variable.

Mechanism
Heavy, continuous grazing may cause further deterioration resulting in a shift to the Club Moss Plant Community.
Mechanism
Excessive defoliation (i.e., areas of heavy animal concentration) or cropped go-back land with continuous grazing will convert the plant community to the Annual/Pioneer Perennial Plant Community.
