Description
This plant community is dominated by cheatgrass and annuals. Root sprouting shrubs such as rabbitbrush and greasewood can be present, dependent upon, how frequent, fire has occurred. This state has developed due to frequent fires and/or improper grazing management. Some soil loss has occurred. This site has crossed the threshold. It is economically impractical to return this state to State 1 with accelerated practices.
Description
This plant community has gone over the threshold to a new site. Site potential has been reduced. Significant soil loss has occurred. Infiltration has been reduced and run-off has become more rapid. This state has developed due to continued improper grazing management and/or frequent fires.
Mechanism
Develops through frequent fire and/or improper grazing management. This site has crossed the threshold. It is economically impractical to return this state to State 1 with accelerated practices.
Mechanism
Excessive soil loss and changes in the hydrologic cycle caused by continued improper grazing management and/or frequent fire cause this state to cross the threshold and retrogress to a new site with reduced potential. It is economically impractical to return this state to State 1 with accelerated practices.
