REVEGETATION <br />• Seeding and Shrub Planting <br />No new seeding was conducted at Seneca II. No shrubs or trees were planted at Seneca II Mine <br />in 2012. <br />• Weed Control <br />Survey for noxious weeds was carried out on the Seneca II Mine permit area in 2012. No weed <br />spraying was conducted at the Seneca II Mine in 2012. The weed control areas will continue to <br />be monitored in 2013 for effectiveness and necessary retreatment. <br />• Revegetation Monitoring <br />Revegetation monitoring of permanently revegetated areas was conducted during the summer of <br />2012 by ESCO Associates, Inc. The 2012 Annual Revegetation Monitoring report will be <br />submitted as a separate document. <br />• Grazing <br />Cattle (160 long yearlings) were moved on to the Seneca II reclaimed area August 15 2012. All <br />cattle were moved off the Seneca II Mine area September 11 2012. See attached 2012 Grazing <br />Plan Map for pasture locations. <br />This grazing scheme resulted in a total of 128 AUM's for 2012. <br />Assumptions: 1 long yearling = 0.8 AUM, requiring 648 pounds of forage per month. (One <br />AUM requires 810 pounds of forage). <br />The AUM usage is calculated using the following assumptions: <br />Assumptions: <br />Average production = 1,172 lbs. /acre (see 2007 and 2008 Revegetation Monitoring Report) <br />Total reclaimed area = 271 acres (included Pre -Law area) <br />One AUM requires 810 lbs. of forage <br />1,172 lbs /acre (x) 271 acres = 317,612 lbs. of total forage produced <br />810 lbs. of forage (x) 128 AUM's = 103,680 lbs. of forage required; <br />Therefore, <br />103,680 (/) 317,612 (x) 100 = 32.6% utilization of the total Seneca II reclaimed area <br />7 <br />
