An integration of one or more of these methods will be applied. In general, weeds will be controlled by minimizing disturbed areas and re-vegetating affected areas as soon as possible following disturbances. Each year, prior to the growing season, the site will be inspected to assess noxious weed growth and establish control procedures for the season. Weed management will likely include both mechanical and chemical controls. Biological controls are not anticipated at this time. For the Serfer pit mechanical management practices will consist of localized weed removal by machinery and possibly mowing. Chemical spraying will be used to manage weeds in reclaimed areas. Connell will spot spray as per the product specifications to eliminate noxious weeds. Ln Specific management strategies for some undesirable weeds that can be present are as follows: For a more complete list see attachments for List A, B, and C LU Species. 00 00 Cn 1. Canada Thistle 00 A. Mechanical and Chemical Control - Mowing can occur throughout theLn growing season in order to keep the plants from going to seed. co Mowing should be terminated in late August followed by an herbicide treatment during late September through October, before a hard frost. B. Cultural and Chemical Control - Use a short residual herbicide • followed by a seeding with a competitive grass such as smooth brome or other sod forming species (natives preferred). C. Chemical Control Only - Herbicide applications can be applied from - rosette to bud stage and if needed, retreated in the fall. 2. Musk Thistle A. Mechanical and Chemical Control - Mowing to occur throughout the summer to address the bud stage of the thistle. Apply an herbicide in cc October to new rosettes and any bolted plants. B. Mechanical Control Only — Conduct multiple mowings during the summer(two to four) to keep seeds from being produced. LU C. Chemical Control Only — Use an herbicide that is not harmful to aquatic wildlife and vegetation in the spring and fall. 3. Diffuse Knapweed A. Cultural and Chemical Control - Apply herbicide in early summer Ln co when knapweed is in the rosette through bolting stage. Reseed area with competitive perennial sod forming grasses. Another herbicide application utilized the following year as needed to prevent plants from going to seed. Uj B. Mechanical and Chemical Control — During the growing season, mow when the knapweed is in the bud stage to prevent seeding. If Uj necessary, an herbicide application to any plants that have re-bolted will be made in the fall. LU 243
