2nd Weed Control Objective: <br />3 d Weed Control Objective: <br />3.0 Evaluating Weed Control: After you have created weed control objectives and have <br />begun to control the priority weed species on your mine site, you should evaluate the results <br />of your control methods. This requires follow -up visits to the areas where weeds were <br />controlled and re- assessment of the size and density of an infestation. (For example, <br />compare the size of the infestation after a growing season has elapsed to size before control <br />actions were initiated.) In most cases, the elimination of an infestation will take several years <br />with multiple treatments per year to kill the plants and eliminate the bank of weed seeds in the <br />soil. (See Table 2.1) <br />4.0 Analyzing the Effectiveness of Weed Management: After you have analyzed the <br />control results (in some cases over the course of several years), you can determine if the <br />weed control objectives helped you achieve your management goal(s). Make sure to consider <br />the cost of control compared to the benefits realized from weed control. If the benefits of <br />control did not outweigh the cost, it might be better to create new objectives or try other <br />control methods. (For example, it may be more cost effective to use containment and <br />prevention techniques to maintain the current level of weed infestations and to prevent an <br />increase in weed populations.) (See Table 4.1) <br />Footnote: This Noxious Weed Control and Management Plan is based upon the guide as <br />outlined in the Publication prepared by the Office of Colorado State Parks.
