compliance. Weed treatment during mining will reduce weed management during final <br />reclamation. <br />B. Weed Control <br />IWM is a process by which one selects and applies a combination of management <br />techniques that will control a particular weed species or infestation efficiently and <br />effectively, with minimal adverse impacts to non - target organisms and allows mining to <br />continue. Fremont will implement suggested weed control techniques and treatment <br />timing as recommended in Fremont County Weed Management Preferences chart <br />(Exhibit B). <br />Between July and September, Fremont will apply herbicide to weed patches as <br />necessary until foliage turns yellow. Herbicide will consist of a mixture of 0.5% arsenal <br />and 0.5% glyphosate, commercial surfactant and Hi -Light blue dye. <br />In the event tamarisk trees become established, they will be physically removed with a <br />bobcat loader or by hand, depending on location. <br />C. Monitoring <br />Monitoring is the repeated collection and analysis of information to evaluate progress in <br />meeting resource management objectives. Periodic observation of the weeds being <br />managed is necessary to evaluate the effectiveness of a weed control program. If <br />management objectives are not being met, weed control actions need to be modified. <br />Without some type of monitoring, there is no way of knowing whether control actions <br />are contributing to the fulfillment of management objectives. <br />Environmental regulatory oversight requires at least two site inspections per year. <br />Fremont will monitor the site for weed infestation in the spring and in the fall. Target <br />weeds will be identified from the Fremont County Weed Management Preferences <br />chart (Exhibit B) and Noxious Weeds of Colorado publication by Colorado Weed <br />Management Association. In the event weeds are present, they will be treated as by <br />Fremont County Weed Control officer. <br />REFERENCES <br />CO Weed Management Association, Noxious Weeds of Colorado, 11th Ed. 2013. <br />Fremont County, CO; Weed Management Preferences, February 2010. <br />U.S. Bureau of Land Management, Weed Management Template, www.blm.gov. <br />
