Submodel
States 1 and 5 (additional transitions)
1.1. State 1 Phase A
1.5. State 1 Phase E
Description
State 3. This plant community is dominated by Rocky Mountain juniper. Remnants of Bluebunch wheatgrass and Idaho fescue can be found in the understory, often under trees. Shallow-rooted grasses, such as Sandberg bluegrass, and other annuals can be found in the interspaces. Few shrubs are present. Some soil loss has occurred. This state has developed with improper grazing management and in the absence of fire. Generally, when shrub cover is below 10-15%, bare ground is above 25-30%, juniper cover is greater than 20%, the site has crossed the threshold. It is usually uneconomical to return this community to State 1 through accelerated practices.
Submodel
Description
State 4. This state is a range seeding. It is seeded to adapted improved species or native species that attempt to mimic the native plant community.
Submodel
Description
Unknown new site. 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 frequent fires from State 2 or with continued improper grazing management and the absence of fire from a Rocky Mountain juniper invaded Phase from State 3. This site will not return to State 1 or 2 because of significant soil loss.
Submodel
Mechanism
State 1 Phase D to State 2, Phase B. Develops through improper grazing management and lack of fire. This site has crossed the threshold. It is usually uneconomical to return this community to State1 through accelerated practices.
State 1 Phase E to State 2 Phase A. Develops through improper grazing management with no fire. This site has crossed the threshold. It is usually uneconomical to return this community to State1 through accelerated practices.
Mechanism
State 1 Phase C to State 3. Results from improper grazing management and lack of fire. This site has crossed the threshold. It is usually uneconomical to return this community to State1 through accelerated practices.
Mechanism
It is seeded to adapted improved species or native species that attempt to mimic the native plant community.
Mechanism
State 2 to unknown site. Excessive soil loss and changes in the hydrologic cycle caused by 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 usually uneconomical to return this community to State1 through accelerated practices.
Mechanism
It is seeded to adapted improved species or native species that attempt to mimic the native plant community.
Mechanism
State 3 to unknown site. Continued improper grazing management and lack of fire cause this state to cross the threshold and retrogress to a new site with reduced potential due to significant soil loss and changes in hydrology. It is usually uneconomical to return this community to State1 through accelerated practices.
