effectiveness of treatments (if measurable). The report will be included in the Cresson <br />Project Annual Report submitted to DRMS. <br />2 State and County Regulations <br />CC&V is subject to Teller County and Colorado Department of Agriculture (CDA) <br />regulations requiring all landowners to prevent the spread of state listed noxious weeds in <br />accordance with the Colorado Noxious Weed Act. <br />The Act categorizes noxious weed species into three lists: A, B, and C. List A species are <br />invasive weeds that either do not yet occur in Colorado or are of very limited distribution. <br />Eradication of these species is required. List B species are those for which the state has <br />developed or is currently developing a management plan designed to stop their continued <br />spread. These species must be managed according to the requirements of the Act. List C <br />species are widespread and known to be problematic, but management is not legally <br />required. However, management of List C species may be beneficial to promote <br />vegetation establishment in reclaimed areas and prevent degradation of undisturbed areas. <br />A copy of the Colorado Noxious Weed List is provided in Appendix C. <br />Teller County Weed District collaborates with Park County weed district in emphasizing <br />management of 16 List B species (Appendix B), but reserves the right to enforce the <br />management of any state -listed noxious weed. <br />Any chemical control method used on the mine property must adhere to the Federal <br />Insecticide Fungicide Rodenticide Act (FIFRA). FIFRA makes it unlawful to use any <br />pesticide in a manner inconsistent with the label. The pesticide applicator has a legal <br />obligation to read and follow the label instructions and all material to which the label <br />refers. Only aquatically -labeled herbicides should be applied in or near water, and <br />appropriate records should be kept for compliance with the Colorado 2015 National <br />Pollutant Discharge Elimination System permit. <br />3 Noxious Weed Management Strategy <br />In many cases, noxious weed problems can be overwhelming due to the size and scope of <br />infestations. A recommended approach is to characterize noxious weed infestations at a <br />given site, and set priorities for management based on site conditions, regulatory <br />requirements, land management objectives, available resources, and potential for success. <br />Once priorities have been established, weed management activities should occur using <br />the IPM techniques of mechanical, chemical, and cultural control. By documenting <br />infestations and control efforts, annual management activities can then be modified based <br />on information from the previous year. <br />3.1 Prevention <br />Noxious weeds are spread through the dispersal of seed and/or the transportation of plant <br />propagules (i.e. rhizomes, bulbs, roots, etc.) The most effective method of weed control is <br />Cresson Project Weed Management Plan 2 <br />
