EXHIBIT J - VEGETATION INFORMATION <br /> <br />There ere three distinct vegetative units immediately <br />surrounding the affected area of LP-21: an opea sagebrush <br />park, a strip of sparsely vegetated pinyon-juniper and <br />rockland combination. (For a more detailed location, see <br />"Exhibit C".) <br />The big sagebrush (Artemesis tridentata) - sand dropseed <br /> <br />(Sporobolus cryptandress) association, on a gently undulating <br />1-~96 slope, correlates closely with a reddish-brown loamy <br />soil. Other lesser species found in this association are: <br />fourwing saltbush (Atriplex canescens), big rabbitbrush <br />(Chrysotamnus nauseosus), snakeweed, blue grams (Bouteloua <br />gracilis), galleta grass (Hilaria jamesii), Indian ricegrass <br />(Oryzopsis hymenoides), pricklypear (Opuatia app), Russian <br />thistle (Salsola kali), scarlet falsemallow, western wheatgrass <br />(Agropyron smithii), and sunflower (Helianthus app). Vegetative <br />cover for this big sagebrush-sand dropseed association averages <br />15 percent. Dominant vegetation averages two to three feet <br />in height. <br />Between the steep south-facing slope and the sagebrush <br />park lies a strip of pinyon-juniper whose vegetive cover <br />approximates six percent. Moving from the park area towards <br />the hillside and portal area, the soils trend is to grade <br />into a clay loam from a loam. The average height of the <br />dominant vegetation ranges from 10 to 20 feet. <br />The pinyon-juniper association thins out up the south- <br />f Pacing slope as soil contains more clay and thins out, and <br />water infiltration decreases. Vegetative cover is less than <br />5%, with an abundance of rockland present. <br />
