infestation so that it does not become a problem, or to keep certain weeds off of the mine <br /> 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 <br /> greatest threat to achieving the management goals for the mine site and which can be <br /> most easily controlled are the highest priority for management. <br /> To create weed control objectives for your weed management plan, first search your mine <br /> site 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 <br /> to which weed species are present on the mine site, how large the infestations are, <br /> and where on the property they are located. <br /> 2) Read the weed species profiles for the species you identified and fill out columns 4- <br /> 7 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 <br /> Lands with Natural Values. (Hereafter called the Handbook) <br /> Move on to Section 2.2 to determine the management priority of each weed species. <br /> 2.2 Prioritizing Weed Species: Determine the management priority of each weed <br /> species on the mine site by using the Alien Plants Ranking System outlined in <br /> Appendix 6 of the Handbook, or by consulting your County Weed Supervisor. <br /> Species that have the highest priority for management should receive a "priority <br /> check" in the table, and should be controlled first. Use the information in the table <br /> about the weeds "life cycle" (emergence and flowering) to coordinate times and <br /> methods of control. (For example, several species on your list may be controlled <br /> best when cut or pulled after bolting but before seed production. If these species <br /> have similar life cycle characteristics they can all be controlled at the same time. <br /> Coordinating control methods in this manner will help save time, resources and/or <br /> money.) <br />
