The slopes are 2 to 5 percent. <br />Runoff is medium, the hazard of wind erosion is severe and the hazard of water erosion is <br />moderate. Precipitation ranges from 9 to 18 inches a year and weather conditions are quite cold <br />year round. The soils present are consistent with a typical dry mountain loam range site. <br />The existing vegetation includes streambank wheatgrass, sheep fescue, muttongrass, pine <br />needlegrass, Letterman needlegrass, Sandberg bluegrass, junegrass and traces of bluebunch <br />wheatgrass, squirreltail, and Nevada bluegrass. These grasses form a sparse stand beneath an <br />open stand of big sagebrush, with smaller amounts of bitterbrush and rabbitbrush. Forbs on the <br />site include lupine, pussytoes, aster, fleabane, yarrow, bluebells, buckwheat, phlox, fringed sage <br />and snakeweed. <br />Therefore, the following reclamation mix is recommended: <br />Common Name <br />Scientific Name <br />% of Mix <br />Cool/Warm <br />Ht (ft) <br />Mountain Brome <br />Bromus marginatus <br />20 <br />Cool <br />1 -3' <br />Slender Wheatgrass <br />Elymus trachycaulus <br />20 <br />Cool <br />1.5-4' <br />Streambank Wheatgrass <br />Elymus lanceolatus <br />10 <br />Cool <br /><1'' ° <br />Rocky MadIdaho Fescue <br />Festuca saximontana <br />10 <br />Cool <br />1.2' <br />Prairie Junegrass <br />Koeleria cristata <br />5 <br />Cool <br />1 -2' <br />Thickspike Wheatgrass <br />Elymus lanceolatus <br />10 <br />Cool <br />1 -3' <br />Beardless Wheatgrass <br />Pseudoroegneria spicata ssp.
