Alkali Bottom

Description

When this range site is near its potential, alkali sacaton, western wheatgrass, sandberg bluegrass, basin wildrye and inland saltgrass make up over 50 percent of the plant community. Alkali sacaton is dominant on this site making up from 20 to 25 percent of the total annual production on the site. Other grasses that occur in the community are sand dropseed, galleta, foxtail barley and a number of sedges and rushes.

Forbs such as scarlet globemallow, sulphur bukcwheat, tufted eveningprimrose, rosy gilia and fileree make up to 10 percent of the potential plant community.

Shrubs such as black greasewood, nuttall saltbush, spiny hopsage, shadscale, fourwing saltbush, prickly pear and basin big sagebrush make up to 25 to 35 percent of the potential plant community. As the plant community declines in condition the grasses and forbs will decrease while the shrubs black greasewood and basin big sagebrush will increase and dominate the site.

Shrubs and trees less than 4 1/2 feet tall 5 to 15% of total.
