season, the site will be inspected to assess noxious weed growth and establish <br />control procedures for the season. Weed management will likely include both <br />mechanical and chemical controls. Biological controls are not anticipated at this <br />time. For the Tucker Carr pit mechanical management practices will consist of <br />localized weed removal by machinery and possibly mowing. Chemical spraying <br />will be used to manage weeds in reclaimed areas. Connell has employed a <br />commercial spraying company as a consultant to identify and spray based on the <br />weeds <br />Specific management strategies for some undesirable weeds that can be present <br />are as follows: For a more complete list see attachments for List A, B, and C <br />Species. <br />1. Canada Thistle <br />A. Mechanical and Chemical Control - Mowing can occur throughout the <br />growing season in order to keep the plants from going to seed. <br />Mowing should be terminated in late August followed by an herbicide <br />treatment during late September through October, before a hard frost. <br />B. Cultural and Chemical Control - Use a short residual herbicide <br />followed by a seeding with a competitive grass such as smooth brome <br />or other sod forming species (natives preferred). <br />C. Chemical Control Only - Herbicide applications can be applied from <br />rosette to bud stage and if needed, retreated in the fall. <br />2. Musk Thistle <br />A. Mechanical and Chemical Control - Mowing to occur throughout the <br />summer to address the bud stage of the thistle. Apply an herbicide in <br />October to new rosettes and any bolted plants. <br />B. Mechanical Control Only - Conduct multiple mowings during the <br />summer (two to four) to keep seeds from being produced. <br />C. Chemical Control Only - Use an herbicide that is not harmful to <br />aquatic wildlife and vegetation in the spring and fall. <br />3. Diffuse Knapweed <br />A. Cultural and Chemical Control - Apply herbicide in early summer <br />when knapweed is in the rosette through bolting stage. Reseed area <br />with competitive perennial sod forming grasses. Another herbicide <br />application utilized the following year as needed to prevent plants from <br />going to seed. <br />B. Mechanical and Chemical Control - During the growing season, mow <br />when the knapweed is in the bud stage to prevent seeding. If <br />necessary, an herbicide application to any plants that have re -bolted <br />will be made in the fall. <br />C. Mechanical Control Only - To reduce seed set, mow throughout the <br />summer season. <br />D. Chemical Control Only - The herbicide application is to be made <br />during the rosette stage (spring or fall) and while bolting. <br />2 <br />
