Description
The dominant aspect of the this site is a grassland with low growing shrubs. Major grasses are salina wildrye, galleta, Indian ricegrass, Shrubs include Bigelow sagebrush, shadscale, and black sagebrush. Wyoming big sagebrush occurs at the higher elevations of the site.
State 1 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 plant community in this state is a shrubland comprise of half shrub and shrubs with some perennial grasses and non native annual plant species. Cool season grasses are still present but in reduced amounts with increased amounts of warm season perennial grasses. Introduced annual grasses and forbs are present and common to the site. At the higher elevations there may an increase of sagebrush species along with other shrub species, including roundleaf buffalo berry.
Submodel
Mechanism
Prolonged drought, continuous heavy grazing, surface disturbance, introduction of non-native annuals. Improper grazing management along with drought can reduce perennial grass species and promote shrub dominance. Increased surface disturbance allows for the germination and establishment of introduced annuals.
Mechanism
If possible; restoration might be a combination of practices including brush management, herbaceous weed treatment, range planting, and prescribed grazing management.
Context dependence
The sites steep slopes, high surface rock content, and salinity content may limit the effectiveness and extent of restoration practices and applicability.
