applications occurred June 29 - 1, July 24 - 27 and August 23 - 24, 2006. Weed control <br />efforts during 2006 were prioritized under the direction of Ken Cazlson of Habitat <br />Weeds were managed with chemical applications to control Canada thistle, musk thistle, <br />yellow toadflax, mayweed chamomile and oxeye daisy. Other weed species were not <br />found or considered a priority for control this yeaz. Work during the summer focused on <br />areas around lower Robinson Lake, Robinson Tailings Pond, Eagle Park Reservoir, Lake <br />Erwin, biosolid stockpiles, One Dam, Two Dam, Searle Gulch, Mayflower Tailings Pond <br />and Mayflower Dam. Roads throughout these sites were treated including the access gate <br />along highway 91 just south of Robinson Tailings Pond and roads just south of the main <br />gatehouse along Highway 91. On August 23 - 24 woody shrub and tree species of <br />willow, subalpine fir, and Engelmann spruce were sprayed on Eagle Park Reservoir Dam <br />to prevent deep rooting and maintain the structural integrity of the dam. A summary of <br />areas treated, chemical names and quantities applied are available in Appendix A. <br />The most prevalent weed found during the 2006 growing season was yellow toadflax. <br />South of the main gatehouse on the west facing slope towards highway 91 large stands of <br />yellow toadflax were present. Dense yellow toadflax infestations were present around the <br />perimeter of Robinson Lake, south facing slopes north of Robinson Lake and a staging <br />area below one dam. West of Lake Erwin and One Dam were significant populations of <br />yellow toadflax. Dense stands of yellow toadflax were present at the base of Tluee Dam, <br />Mayflower Dam, north of Mayflower Dam and roads throughout. Avery severe <br />infestation of yellow toadflax east of Mayflower Dam was present in high density. <br />Second in severity was oxeye daisy concentrated in the northwest region of the mine. <br />Patches of oxeye daisy were concentrated in areas and roads south of Eagle Park <br />Reservoir to Robinson Lake. South of Robinson Tailings Pond were small populations of <br />oxeye daisy. South of the main gatehouse along highway 91 on the west facing slope, <br />sparse stands of oxeye daisy were found. <br />Climax Mine: IPM Report 2 2/22/2007 <br />
