• Shrub Plots. Approxunately 9,954 seedlings and 2,000 one gallon sized shrubs were planted at Yoast. <br />The shrub plot locations are shown on the attached 2007 Chronological Seeding map. Following is <br />the breakdown indicating the number of seedling species planted in each area. <br /> Plot Desi nation <br /> 2007-1 2007-2 <br />Species Fenced Fenced 2007-3 2007-4 2007-5 Total <br />Aspen (10cu) 400 188 0 0 0 588 <br />Aspen (1 gal) 2,000 0 0 0 0 2,000 <br />Chokecherry 2,942 2,942 0 1,000 0 6,884 <br />Cottonwood 0 0 205 0 500 705 <br />Serviceberry 0 0 0 895 0 895 <br />Willow 0 0 441 0 441 882 <br />TOTAL 4,942 2,942 646 1,895 941 11,954 <br />• Monitoring <br />• ESCO Associates, Inc conducted revegetation monitoring of permanently revegetated areas during <br />the summer of 2007. The 2007 Annual Revegetation Momtonng report is submitted under separate <br />cover. <br />• Weed Control <br />Survey for noxious weeds was carried out on the Yoast Mine permit area in 2007. Monitoring was <br />conducted in 2007 to determine the need or level of retreatment necessary for areas sprayed in 2006. <br />Canada thistle was the primary target species in all control areas, with lesser activity directed towards <br />areas of hounds tongue and whitetop. Control areas were sprayed in May and June. A spot spray gun <br />was used to concentrate control activities on target areas, reducing potential impacts to adjacent <br />desirable vegetation. The herbicide mix, based on recommendations from the Colorado State <br />Extension Service, was mixed and applied by Dillon Contracting who is a certified commercial <br />applicator. The weed control areas will continue to be monitored in 2008 for effectiveness and <br />necessary retreatment. See attached weed control daily log spreadsheet and the 2007 Weed Spray <br />Location map for a detailed description and location of the 2007 herbicide application. <br />SEDIMENTATION POND SURVEYS <br />SCC is required by Permit C-82-057 to monitor sedimentation ponds for sediment storage capacities. <br />This schedule provides a sediment yield history and gives advance warning to operations personnel <br />when sediment clean-out work is required. In accordance with Rule 4.05.6(11)(c), SCC visually <br />inspects each pond a minimum of quarterly each year. During these inspections, any drastic change in <br />sedimentation storage or sudden increase in a sediment delta at the inlet to the pond could be <br />• detected which would require mitigation. <br />Based on the 2007 survey, all sediment ponds have sufficient sediment storage. Additionally, all ponds <br />have been discharging in compliance with the approved NPDES permit effluent limitations. Yearly <br />
