patches with light density for all noxious species encountered. Compared to 2011, this <br />area has decreased noxious weed cover likely due to repeated treatments with different <br />herbicide mixtures. However, treatment is still recommended for 2013 to maintain this <br />decreasing trend. <br />County Road 81 <br />In the interest of controlling potential vector infestations to CC &V, Habitat Management <br />was asked to spray an off -mine area consisting of an approximately 0.3 mile stretch of <br />right -of -way along the east side of County Road 81, just outside the town of Victor. <br />Treatments along the County Road took place on July 10. The area within 10 feet of <br />County Road 81 had several large infestations of Canada thistle and yellow toadflax <br />ranging from 20 — 25 square feet and Dalmatian toadflax and musk thistle in several <br />scattered patches ranging from 9 — 12 square feet in size. These patches have reduced in <br />size since the 2011 application. Monitoring and continuing treatment of this site is critical <br />to prevent spreading of this infestation onto the CC &V Mine. <br />Slopes & Intersections near the Transfer Station and Crusher <br />The slope above the crusher continues to be a problem area for weeds. Treatment took <br />place on July 11. The populations of musk thistle, Canada thistle and yellow toadflax <br />have the same densities as 2011 and this year Dalmatian toadflax was also present. This <br />introduction could be from the seed bank or from the spread of existing populations on <br />the mine site. The largest infestations were Canada thistle and yellow toadflax. This area <br />lacks many native species and is mainly dominated by noxious weeds. Continued <br />herbicide applications are important for decreasing the populations of noxious weeds <br />along with establishing native vegetation to compete with the weeds. <br />Topsoil Stockpile near the Crusher <br />Habitat Management has not treated this area in the past years. Musk thistle, Canada <br />thistle, yellow toadflax and Dalmatian toadflax were treated on July 11. The dominate <br />species is musk thistle with large, dense patches throughout the stockpile with majority <br />on the slopes. The other noxious weeds were in small scattered patches primarily found at <br />3 <br />
