Submodel
Submodel
Description
Creosotebush (12-30%), bush muhly (0-15%), few intershrub grasses, moderate soil loss
Description
Perennial grasses (3-20%), creosotebush (0-12%). Typically a product of shrub removal via herbicides
Mechanism
Continuous heavy grazing, thinning and patchy loss of black grama or other important grasses, shrub proliferation
Mechanism
Shrub control associated with grazing deferment or prescribed grazing; weather patterns permit recovery of black grama or other reference grasses
Mechanism
Loss of remaining interspace grasses, gradual loss of soil organic matter, infill of shrubs, and soil erosion
Mechanism
Shrub control after grass becomes sparse or followed by poorly planned grazing
Mechanism
Shrub control after soil loss is significant, precluding substantial grass recovery
