2008 Weed Management Activities <br />Habitat Management is a licensed commercial pesticide applicator that performed weed <br />management activities at Climax during the 2008 growing season. Qualified supervisor <br />Paul Selby led a crew of trained technicians in applying herbicides to targeted weeds on <br />the Climax site. Periodic herbicide applications occurred throughout the 2008 growing <br />season beginning July 23 and ending August 13. Herbicide spraying coincided with other <br />reclamation projects completed by Habitat Management to minimize mobilization costs. <br />Weed control efforts during 2008 were prioritized under the direction of Gary Slifka of <br />Climax and Ken Carlson of Habitat Management. <br />Targeted herbicide spraying was used to control Canada thistle, musk thistle, yellow <br />toadflax, mayweed chamomile and oxeye daisy. Other noxious weed species were not <br />found in areas managed this year. Work during the summer focused on areas and roads <br />around Robinson Lake, Robinson Lake Dam, Eagle Park Reservoir, Robinson Tailings <br />Pond, McNulty Gulch, biosolids stockpiles, 1 Dam, 2 Dam, Searle Gulch, Mayflower <br />Tailings Pond, Mayflower Dam, Storke Yard and Arkansas River Restoration. A <br />summary of areas treated, chemical names and quantities applied is available in <br />Appendix A. <br />Herbicide solutions were spot sprayed to targeted weed species with ATV sprayers in <br />most areas and with backpack sprayers in less accessible areas. An herbicide solution of <br />Tordon 22K was sprayed on yellow toadflax, while an herbicide solution of Milestone <br />was sprayed on Canada thistle, musk thistle, mayweed chamomile and oxeye daisy. <br />These herbicides are all broadleaf selective and have a very low potential for injury to <br />surrounding desirable native grass species. MSO Premium, a surfactant that increases leaf <br />adhesion and absorption, was included in herbicide solutions in addition to blue marker <br />dye to track applications. For aquatic and wetland sites, the aquatic use approved <br />herbicide Garlon 3A was sprayed. <br />3 <br />Climax Weed Report 1/22/09
