preventing the introduction and spread of noxious weeds on the site. Preventative <br />measures should be given the highest priority for implementation. A combination of <br />methods and practices can be employed to prevent the introduction and spread of weed <br />species on the mine. <br />1. Thorough cleaning of equipment before entering the mine or new areas to prevent <br />the introduction of plant propagules from other sites. <br />2. Seed mixtures used for revegetation or temporary site stabilization will be free of <br />noxious weeds. <br />3. Hay, straw, and/or other materials used for mulch or other purposes will be <br />Colorado State certified as weed free. <br />4. Periodic surveys will be conducted to identify any new weed infestations. Any <br />new infestations should be mapped and scheduled for management before they <br />become well established. <br />5. CC&V will communicate and coordinate with adjacent land holders whose <br />properties may be infested with weeds, but CC&V assumes responsibility of <br />mitigation to mine property only. Establishing partnerships for weed management <br />within the local area is essential for successful long-term weed management. <br />6. Early detections and rapid response for new noxious weed infestations that <br />threaten otherwise uninfected areas. <br />3.2 Noxious Weed Survey and Prioritizations <br />A noxious weed survey should be conducted to identify the extent of noxious weed <br />infestations and to document their locations. This inventory should be conducted on all <br />mine property prior to or in conjunction with management activities in the spring of <br />2015. County and state listed noxious weed infestations should be identified in the <br />survey, and data used to determine the appropriate strategy for containment, control, or <br />eradication these noxious weed species. The survey will help to inform management <br />priorities for infested areas. Treatment areas should be prioritized by infestation level, <br />ease of access, and ability to spread. <br />The use of GPS technology may be utilized to track the location and status of noxious <br />weed infestations. Infestations discovered during treatment should be added to the <br />existing survey data. Surveys can often be conducted during management activities, <br />especially after the initial survey. <br />Initial survey information should be used to prioritize management activities. Infestations <br />that are small, sparse, and in isolated (otherwise uninfested) areas should be given the <br />highest priority, as well as infestations in areas with a high potential to spread. By <br />managing these types of infestations first, impacts of management efforts are maximized <br />Cresson Project Weed Management Plan <br />
