Mechanism
Loss of biotic integrity due to loss of perennial grasses and shrub encroachment, causing some loss of soil site stability and hydrologic function with more stability and infiltration under shrubs.
Mechanism
Loss of biotic integrity due to loss of perennial grasses and juniper and shrub encroachment, causing some loss of soil site stability and hydrologic function.
Mechanism
Further loss of biotic integrity with increasing juniper. Soil site stability and hyrdologic function at least moderately departed from the reference state due to changes in infilration pattern.
Mechanism
Drought, unmanaged grazing and/or fire removes the perennial herbaceous component of the plant community. Introduced annual grasses and forbs move into the plant community further reducing the biotic integrity of the site. Soil site stability is lost except around remaining trees and shrubs.
Mechanism
Reduction of juniper and other woody shrubs that have encroached on the site. Seeding or planting where remaining seed source is inadequate. Well managed grazing before and after treatment.

Mechanism
Drought, fire, and/or unmanaged grazing reduce the perennial herbaceous component and some of the shrubs further reducing the biotic integrity of the site. Introduced annual grasses and forbs move into the plant community. Soil site stability and hydrogic function are at least moderately departed from the reference state.
Mechanism
Reduction of junipers and shrub species that have encroached on the site. Seeding where there is not an adequate seed source of the desired species. Control of introduced grasses and fobs may be needed if they are significant on the site. Well managed grazing is required before and after treatment.
