2.1 IDENTIFICATION, MAPPING, AND ASSESSMENT The first step in successful weed management is to survey the property and identify problem weed species growing on site, including the location and level of infestation. This information enables effective management decisions that optimize weed control practices on a site specific basis. Potential sources for the introduction and spread of weeds on the site can be identified and managed. Existing infestations can be assessed to determine their negative impacts and potential to spread. This information can then be used to determine priorities for management efforts. Site specific information and infestation chazacteristics aze used to identify the best control methods, and plan their implementation. Using this approach optimizes weed treatment effectiveness, particularly when more than one type of treatment is to be used at one or more times during the growing season. Beginning in the spring of 2006 on an annual basis, P&M will conduct a through assessment of weed infestations within the permit area. The project area will be inspected to assess site conditions such as slope and terrain, routes of access, weedy species present, potential vectors for weed species invasion (i.e., roads, livestock grazing practices, etc.), desirable species present (among weedy species), locations of water bodies, potential sources of mn-on and run-off, wind conditions, and other factors relevant to weed control planning. Information collected for weed infested areas will include the weed species present, location (mapping with a GPS unit is recommended), size, and density. Noxious and pest weed infestations will be identified and delineated by qualified specialists during the active growing season of each year. Specific treatment and monitoring methodologies and timetables will be developed based on weed species of regulatory concern, location and extent of the infestation(s), and other pertinent environmental and site factors. Weed management efforts will focus on weedy plant species listed in the Routt County Noxious Weed Management Plan, DMG Guidelines for weed management, and species on the Colorado State Noxious Weed list, as well as any other plant species that be have a negative effect on natural and reclaimed areas. Of special importance are "A" list species which aze required by state law to be eradicated, as well as "B" list species for which the state has developed or is currently developing a management plan. (The Colorado Noxious Weed Act, Rules pertaining to the Act, the state weed list and state management plans can be found at: http:f/www.ag.state.co.uslcsdlweeds(weedhome.html) Species prioritized by Routt county and the DMG are listed in Table 1. The Colorado State Noxious Weed List can be found in Appendix C. P&M Edna Mine 3 02/24/06
