State 1
Reference Plant Community
Submodel
Description
This state has native shrubs and grasses, but now has introduced non-native annuals in the plant community. This is a loss of biotic integrity and degradation of soil site stability. Severe droughts, unmanaged grazing and frequent soils surface disturbance has allow for the introduction and establishment of non-natives. During periods of above average precipitation annuals can produce moderate amounts of cover.
Submodel
Description
This state is dominated by trees and shrubs with native and non-native annuals. Grasses are mostly absent or severly reduced. Bare ground patches are large and connected within the woody canopy. There are active signs of erosion and deposition.
Submodel
Mechanism
Introduction of non-native annuals species creates an irreversible change in the plant community
Mechanism
Continuous heavy grazing and/or continous soil surface distance, natural tree regeneration/lack of fire, Introduction of non-native annuals, reduced perennial cover.
Mechanism
Continuous heavy grazing and/or continous soil surface distance, natural tree regeneration/lack of fire, loss of perennial cover.
