Description
The Reference State (State 1), moves through many phases depending on the natural and human caused forces that impact the community over time. State 1, described later, indicates some of these phases. The reference Plant Community Phase is 1.1. This plant community is dominated by Wyoming big sagebrush, Sandberg bluegrass and bottlebrush squirreltail. Subdominant species may include Indian ricegrass, bluebunch wheatgrass, Thurber’s needlegrass, longleaf phlox and globemallow. The plant species composition of Phase 1.1 is listed later under “Reference Plant Community Phase Plant Species Composition”.
Submodel
Description
State is dominated by Sandberg bluegrass and non-native annual species.
Submodel
Mechanism
Develops through frequent fire with or without prescribed grazing management. This site has crossed the threshold. It is economically impractical to return this plant community to State 1 with accelerating 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 retrogress to a new site with reduced potential. It has crossed the threshold. It is economically impractical to return this plant community to State 1 with accelerating practices.
