Description
The Reference State (State 1), moves through many phases depending on the natural and man-made forces that impact the community over time. State 1, described later, indicates some of these phases. The Reference Plant Community Phase is Phase 1.1. 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 annual non-native species along with Sandberg bluegrass.
Submodel
Description
Undocumented state that may occur with extensive degradation, such frequent fires.
Mechanism
Develops from Phase 1.2 with frequent fire or from Phase 1.3 with improper grazing management. This site has crossed the threshold. The plant community cannot return to State 1 because needed significant inputs are uneconomical.
Mechanism
The site has deteriorated further and soil loss has occurred resulting in a loss of site potential. This has resulted from improper grazing management and frequent fires. This site has crossed the threshold. The plant community cannot return to State 1 because needed significant inputs are uneconomical.
