applications for both spring and fall along the 0.3 mile stretch of County 81 and roadsides close to the Victor Trails and South Mine entrance. Toadflax species and Canada thistle in Lower Squaw Gulch appear to be on the decline, but still pose a significant concern due to their tendency to reproduce rapidly through perennial root buds as well as seed banks. Though a high level of success has been achieved over the course of 2010, 2011 and 2012 visits, diligent monitoring and annual follow -up applications in this area should remain a high priority for purposes of maintaining the current level of control and to prevent re- infestation from populations currently occupying the Highway 67 roadside and Upper Squaw Gulch. The Lower Squaw Gulch should be allocated one day for treatment in fall and spring of 2013. The budget allocated in 2012 was sufficient to control a significant number of problem infestations. However, in 2013 consideration should be given to the fact that intensive herbicide application efforts will likely be necessary on the topsoil stockpiles, County Road 81, Lower Squaw Gulch, and potentially off -site areas in proximity to the Victor Trails. In order to ensure adequate coverage of areas not treated in 2012 including follow - up treatments in Upper Squaw Gulch, VLF, the Victor Trails, and Arequa Gulch, Habitat Management recommends that CC &V consider a five day treatment visit in both the spring and fall of 2013. While budget limitations have only allowed for a single early season treatment in past years, Habitat Management strongly recommends two treatments in 2013 to significantly reduce weed infestations. 7
