The Aspen Test Plot was constructed, fenced and imgation system installed to the site. During the fall of 2004, 400 selected aspen trees were planted according to the plan and timetable included in the Seneca II-W perm it document. The study examined growth, survival, and • water status during the 2005 growing season. The aspen study report, `Tranrplanting fLpen on Reclaimed Coal-Mine Iltndr Uring Drip Irrigation"is includ ed as an Attachment to this ARR. • Monitoring ESCO Associates, Inc conducted revegetation monitoring of permanently revegetated areas and shrub establishment monitoring in the shrub plot areas doting the summer of 2005. ~ The 2005 Annual Revegetation Monitoring report is submitted as a separate document. • Weed Control Survey fox noxious weeds was carried out on the II-W Mine permit azea in 2005.

The applied herbicide consisted of a tank mix of 2.5 gallons of 22K Tordon and 2.5 gallons of 2,4,D and 250 gallons of water. Escort at the rate of one (1) oz. per acre was spot sprayed on the whitetop. Control areas were sprayed in June, July and September. See attached map, 2005 Weed Spray Locations, for the extent of weed control spraying: . A spot spray gun was used to concentrate control activities on target areas, reducing potential impacts to adjacent desirable vegetation. The herbicide mix based on recommendations'from the Colorado State Extension Servtce, was mixed and applied by the Seneca Mine Reclamation Manager who is a certified applicator. The weed control areas will continue to be monitored in 2006 for effectiveness
