Once you have prioritized the species that should be controlled, and selected the most <br /> efficient time and method to control, you can write your control objectives. <br /> 2.3 Weed Control Objectives: <br /> 15t Weed Control Objective: <br /> 2nd Weed Control Objective: <br /> 3rd 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.)
