2.0 Weed Control Objectives: Objectives are derived from your management goals. They are <br />formed by inventorying the weeds you have on the mine site, determining how they affect <br />your management goals (For example, does the weed reduce forage? <br />Poison livestock? Or crowd out native species?), and determining the most efficient <br />ways to control those weeds. Sometimes a weed control objective will be to simply <br />contain an infestation so that it does not become a problem, or to keep certain weeds off of <br />the mine site. <br />* Added to "Management Goal(s)" <br />Knowing which weed species occur on your mine site and where they are located is very <br />important in developing control priorities. Weed species vary considerably in <br />threat that they pose to the resource values of the property. In addition, weed species vary <br />greatly in their susceptibility to control measures. Thus, weed species that pose the greatest <br />threat to achieving the management goals for the mine site and which can be most easily <br />controlled are the highest priority for management. <br />To create weed control objectives for your weed management plan, first search your mine site <br />for weeds (if you have not already done so), then fill out the attached WEED <br />MANAGEMENT TABLE 2.1. <br />2.1 Weed Management Table (see table 2.1): <br />1) Search the mine site and fill in columns 1-3 in the table paying particular attention to <br />which weed species are present on the mine site, how large the infestations are, and <br />where on the property they are located. <br />2) Read the weed species profiles for the species you identified and fill out columns 4-7 <br />in the table. You can purchase the hard copy of the guide from the Colorado State <br />Parks at 1313 Sherman, RM 618, Denver, CO 80203, site document Creating an <br />Integrated Weed Management Plan: A Handbook for Owners and Managers of Lands <br />with Natural Values. (Hereafter called the Handbook) <br />Move on to Section 2.2 to determine the management priority of each weed <br />species. <br />2.2 Prioritizing Weed Species: Determine the management priority of each weed species <br />on the mine site by using the Alien Plants Ranking System outlined in Appendix 6 of <br />the Handbook, or by consulting your County Weed Supervisor. Species that have the <br />highest priority for management should receive a "priority check" in the table, and <br />should be controlled first. Use the information in the table about the weeds "life cycle" <br />(emergence and flowering) to coordinate times and methods of control. (For example, <br />several species on your list may be controlled best when cut or pulled after bolting but <br />before seed production. If these species have similar life cycle characteristics they can <br />all be controlled at the same time. Coordinating control methods in this manner will help <br />save time, resources and/or money.) <br />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.
