State 1
Reference State
Description
The dominate aspect is a shrub canopy of blackbrush with lesser amounts of Mormon tea, fourwing saltbush, Stansbury cliffrose and Bigelow sagebrush. Common grasses include blue grama, sand dropseed, James' galleta and Indian ricegrass. Blackbrush appears to act as a paleo-endemic species in this MLRA and may not be able to or be very slow to reestablish itself after significient disturbance. Plants likely to increase are annual grasses and forbs, perennial forbs and broom snakweed. Plants likely to invade and become established are cheatgrass, Russian thistle and red brome.
Submodel
Description
This state is similar to the Reference State, but non-native annual grasses and forbs have been introduced into the plant community. In the plant communities phases of the Introduced Non-Native State is the amount of annual grasses and forbs is only a small amount (1-3%), but will fluctuate slightly from year to year due to fluctuations in the amount and timing of precipitation. Normal soil surface disturbance expected from moderate levels of livestock grazing may cause the amount of non-native annual grasses and forbs to increase slightly.
