year included: lower portions of Squaw Gulch, a stretch of the east side of County Road <br />81 as it exits Victor, slopes and intersections near the transfer station and crusher, topsoil <br />stockpile near the crusher, dump #4 topsoil stockpile, schist topsoil stockpile, and <br />roadsides leading up to the head frame and south mine entrance. Areas previously treated <br />by Habitat Management, but not visited this year, include: lower and middle Arequa <br />Gulch, the Victor Trails, the water quality testing site several miles down Shelf Road, <br />Victor Leach Field, and fuel storage and electrical facilities. <br />Herbicides were spot- applied to targeted weed species with a UTV- mounted spray rig in <br />most areas and with backpack sprayers in less accessible areas. A mixture of Tordon 22K <br />(picloram), Plateau (imazapic) and Milestone (aminopyralid) was applied to patches of <br />Canada thistle, musk thistle, yellow toadflax, Dalmatian toadflax and common mullein in <br />the lower Squaw Gulch and County Road 81 area. A mixture of Milestone <br />(aminopyralid), Tordon 22K and Telar (chlorsulfuron) was used for County Road 81, <br />slopes and intersections near the transfer station and crusher, the topsoil stockpile near <br />the crusher, dump #4 topsoil stockpile, schist topsoil stockpile, and roadsides leading up <br />to the head frame and south mine entrance. These mixtures of herbicides were used to <br />reduce the risk of developing herbicide resistant weed populations. The differing <br />mixtures were formulated based on the species observed in these areas as well as <br />herbicide application records from previous years. These herbicides are broadleaf <br />selective and have a very low potential for injury to surrounding desirable, native grass <br />species. A surfactant, MSO Premium, was included in the herbicide mixture to increase <br />leaf adhesion and absorption. Additionally, blue marker dye was included in the mixture <br />to track applications. Appendix A contains an inventory of dates, quantities, and <br />application rates of all herbicides and surfactants. <br />Sites Managed <br />Lower Squaw Gulch <br />Herbicide treatments in Lower Squaw Gulch were conducted on July 10. The area <br />includes east side of Shelf Road, extending '/z mile west of Hwy 67 on Shelf Road to <br />Teller County Road 88. In this area, Canada thistle, yellow toadflax, Dalmatian toadflax, <br />musk thistle and common mullein were treated. Weed infestations consisted of small <br />2 <br />
