The reclaimed areas on the Lone Pine Gulch Portal Site exhibit an impressive amount and <br />diversity of vegetative cover, especially considering the drought conditions present on the site <br />throughout the summer of 2002. Vegetative cover estimates were determined by Chuck Florian of <br />Greystone Environmental Consultants, Inc. Table 2 presents the estimated total cover and cover <br />per vegetative species within the vicinity of each soil-pit location. The total estimated cover in the <br />vicinity of soil-pit TS-1 is 26 percent, but the surveyar noted that 22 percent is a more accurate <br />estimate of total vegetative cover for the entire topsoil storage area. Total vegetative cover for the <br />entire reclaimed portal area is estimated to be 19 percent. <br />Table 2 <br />Estimated Total Vegetative Cover <br />Lone Pine Gulch Portal Site <br /> Sam le Number <br /> TS-1 REC-1 REC-2 REC-3 <br />A o ron s 16% 18% 10% 5% <br />Bromus mar inatus 3% 6% 7% 3% <br />Achnatherum menoides 2% 3% <1% 2% <br />Festuca arizonica 3% 1% 3% <1% <br />Poa ratensis <1% 1°Jo <1% <1% <br />S haeralcea rossularii olia <1% <1% <1% <1% <br />Total Estimated Cover 26% 29% 22% 12% <br />A species list of vegetation observed on the reclaimed area was compiled and is included in <br />Table 3. <br />Table 3 <br />Vegetation Species List <br />Lone Pine Gulch Portal Site <br />Scientific Name Common Name <br />A o ron s * wheat ass <br />Bromus mar inatus Mountain brome ass <br />Achnatherum h menoides Indian rice ass <br />Festuca arizonica Arizona fescue <br />Poa ratensis Kentuc blue ass <br />S haeralcea ossularii olia Goosebe leaf lobemallow <br />*Muldple species' ofwheatgrass were applied to the reclaimed areaz during seeding. Cover estimates for Agropyron spp. include: <br />thickspike whea[grazs (Agropyron dasysmchyum), bluebunch wheatgrass (Agropyron spicamm), western wheatgras5 (Agropyron <br />smithii), streambank wheatgrazs (Agropyron riporium), Slender wheatgrazs (Agropyron trachycau/um), pubescent whea[grazs <br />(Agropyron trichophorum), and beazdless wheatgrass (Agropyron inerme). <br />CONCLUSIONS AND RECOMMENDATIONS <br />The first year of reclamation on the Lone Pine Gulch Portal Site is highly successful. Topsoil <br />replacement depths aze more than adequate across the reclaimed area extent. Placement of erosion <br />control blankets on the steepest portions of the portal site have controlled potential erosion <br />problems. Although abelow-average concentration of nitrogen and phosphorus was detected in <br />the topsoil, another application of (30-15-5 NPK) fertilizer in the spring of 2003 should resolve <br />the problem. <br />
