6.4.10 EXHIBIT J -Vegetation Information <br />According to information supplied by the Natural Resources Conservation Services, Native <br />rangeland vegetation in the potential plant community would include Western Wheatgrass, <br />Galleta, Winterfat, Bottlebrush squirreltail, Wyoming big sagebrush and Shadscale. <br />The following listing includes potential vegetation for soil types likely to produce suitable <br />rangeland vegetation. <br />Soil Type Species <br />Dry Bodot Westem Wheatgrass <br />Galleta <br />Winterfat <br />Bottlebrush Squineltail <br />Wyoming Big Sagebrush <br />Shadscale <br />Dry Zyme Western Wheatgrass <br />Galleta <br />Winterfat <br />Bottlebrush Squirreltail <br />Wyoming Big Sagebrush <br />Shadscale <br />Fourwing Sagtbrush <br />Basin Big Sagebrush <br />Vananda Western Wheatgrass <br />Black Sagebrush <br />Galleta <br />Basin Big Sagebrush <br />Indian Ricegrass <br />Under favorable conditions the Dry Bodot, Dry Zyme and Vananda soil types are capable of <br />producing 600 pounds per acre dry weight. Unfavorable conditions reduce the estimated dry <br />weight production to 300 pounds per acre. <br />Current Vegetation <br />The upper, gentler irrigated slopes of the pit disturbance azea is currently covered with a <br />pasture/hay mix of sown grasses. <br />The lower, more steeply sloping or outcrop azea of the pit disturbance azea supports medium to <br />mature cedar trees. Both live and dead Cottonwood trees exist along the buffer zones azound the <br />pit disturbance. <br />Unirrigated portions not covered by an overstory of cedaz aze predominately covered in noxious <br />weeds and cheat grass. Refer to Exhibit J-1 Vegetation for further vegetation information, <br />including cover and height information. <br />J-1 <br />
