Page 7 <br />Percentage <br />Indian Ricegrass.(Oryzopsis hymenoides) 0-5 <br />Squirreltail (Sitanion spp.) 0-5 <br />Other forbs and shrubs no more than 10 percent, total, are: <br />Globermallow (Sphaeraleea spp.) <br />Sego lily (Calochortus nuttallii) <br />Woody aster (Aster spp.) <br />Buckwheat (Fagopyrum spp.) <br />Locoweed (Astragulus spp.) <br />Phlox (Phlox spP.) <br />Snakeweed (Gutierrezia spp•) <br />Prickly pear (Opuntia spp.) <br />Wild onion (Allium spp.) <br />The total annual biomass production varies from year to year. According <br />to the Soil Conservation Services (SCS), a favorable year can produce <br />500 pounds per acre, median years can produce 350 pounds per acre, and <br />unfavorable years can produce 200 pounds per acre of air dry biomass. <br />The Salt Flats range site has a salt tolerant grassland-shrub aspect. <br />The potential plant community on this soil consists mainly of salt grass, <br />(Distichlis spicata), alkali sacaton, galleta, western wheatgrass, <br />(Agropyron smithii), fourwing saltbush (Atriplex canesens), and greasewood <br />(Sarcobatus sPP.). As the range condition deteriorates, these afore- <br />mentioned grasses and fourwing saltbush decrease, forbs and other woody <br />shrubs increase, and undesirable weeds invade the site. The coal waste <br />disposal site appears to be in poor to fair range condition (estimated <br />using the SCS Range Handbook). The optimum ground cover is 20 to 25 <br />percent. <br />The forage value of this range site is high for cattle, horses, cottontails, <br />jackrabbits, and upland game birds; medium for antelope and deer; and low <br />for sheep, and waterfowl. <br />
