arvense was the primary target species in all control areas, with lesser activity duetted towards areas of whitetop <br />(Cazdaria dmbal. The applied herbicide consisted of a tank mix of 2.5 gallons of 22K Tordon and 2.5 gallons of <br />• 2,4,D with 250 gallons of water. Escort at the rate of one (1) oz. per acre was spot sprayed on the whitetop. Control <br />areas were sprayed in May and June. A spot spray gun was used to concentrate control activities on target areas, <br />reducing potential impacts to adjacent desirable vegetation. The herbicide mix, based on recommendations from the <br />Colorado State Extension Service, was mixed and applied by the Seneca Mine Reclamation Manager who is a <br />certified applicator. The weed control areas will continue to be monitored in 2004 for effectiveness and necessary <br />retreatment. <br />Revegetation Monitoring <br />Revegetation monitoring of permanently revegetated areas was conducted during the summer of 2003 by ESCO <br />Associates, Inc. The 2003 annual revegetation monitoring report is submitted as a separate document (ESCO and <br />SCC, 2003). <br />Grazing <br />Long yearlings grazed in the Pecoco Pasture during 2003. On May 15"', 200 head were placed in the Pecoco Pasture. <br />• On July ls[, all cattle were moved ofP the Pecoco Pasture This resulted in 240 animal unit months on [he Pecoco <br />Pasture. Since Seneca was in the process of realigning the fence and working on drainage channels in Wadge <br />Pasture, no cattle grazed the Wadge pasture in 2003. <br />This grazing scheme resulted 240 AUMs of gazing in the 210 acre Pecoco Pasture, which produced 570 AUM of <br />forage based on 2003 field data collected by ESCO. The grazing scheme for the Pecoco pasture resulted in 171 <br />AUMs used. The utilization was 30%. <br />Seneca will conduct annual production monitoring in both Wadge Pasture and Pecoco Pastures during 2004 field <br />season. Since SCC must haul water to the cattle in the Wadge Pasture this pasmre is not utilized as much as the <br />Pecoco Pasture, which has, live water. In 2003, SCC changed the Wadge pasture fence to include stock pond #29 at <br />the lower Wolf Creek reclaimed area. Assumptions: 1 long yearling = .8 AUM, requiring 648 pounds of forage per <br />month, One AUM requires 810 pounds of forage. <br />• 4 <br />
