Target ecosystem state
Select a state
State 1
Reference State
Description
This state represents the most ecologically stable conditions in terms of resistance to erosion. Moreover, this state has the highest potential for productivity and plant diversity.
Submodel
Description
The general aspect of this site is shrubland with an increase of snakeweed, rabbitbrush, mormon tea and a decrease of fourwing saltbush, winterfat and Bigelow sage. Grasses are dominated by blue grama, galleta and dropseeds with a decline of black grama and cool season grasses. This site has an increase of run-off and bare ground.
Submodel
State 3
Juniper State
Description
The general aspect of this site is an overstory of junipers with half shrubs and succulents. The understory is mostly blue grama, galleta with scattered forbs. This site has increased runoff and water flow patterns. Juniper canopies range from 10-20%, depending on grazing intensity, climate fluctuations and fire exclusion.
Submodel
Description
The general aspect of the site is a low shrubland with annuals. Snakeweed and rabbitbrush are the dominant overstory species with low perennial herbaceous cover. Composition of annuals in this state can range from 20-50% depending on climate variation and diturbance frequency.
Submodel
State 5
Seeded Grass State
Description
The general aspect of this site is a grassland. These sites are areas where the juniper overstory has been removed or reduced and the site is seeded with perennial grasses.
Submodel
Mechanism
Drought; season-long grazing providing little rest and recovery for preferred grazed plants during critical growing periods, coupled with high utilization.
Mechanism
Unmanaged grazing, seed source for juniper establishment, lack of fire, climatic conditions favorable for tree regeneration.
Unmanaged grazing can be described here as: Season-long grazing providing little rest and recovery for preferred grazed plants during critical growing periods, coupled with high utilization.
Mechanism
Woody species control, managed grazing

Prescribed Grazing |
Mechanism
Unmanaged grazing, seed source for juniper establishment, lack of fire.
Unmanaged grazing can be described here as: Season-long grazing providing little rest and recovery for preferred grazed plants during critical growing periods, coupled with high utilization.
Mechanism
Invasion of non-native annuals, drought, unmanaged grazing.
Unmanaged grazing can be described here as: Season-long grazing providing little rest and recovery for preferred grazed plants during critical growing periods, coupled with high utilization.
Mechanism
Tree canopy is reduced thru mechanical methods or burning; managed grazing, favorable climate
