NOXIOUS WEED IDENTIFICATION <br />Noxious weeds are defined as an alien plant that has been designated by State rule as <br />being noxious or has been declared a noxious weed by a County Advisory Board and <br />meets one or more of the following criteria: <br />• are aggressive invaders, detrimental to agriculture or native plant communities, <br />• may be poisonous to livestock, <br />• may be carriers of or hosts to insects, diseases or parasites, <br />• are detrimental to sound management of native or agricultural ecosystems. <br />Proper identification of noxious weed species is extremely important for eradication or <br />control efforts. A private contractor qualified in noxious weed identification has been <br />contracted to perform site inspection to inventory noxious weeds at this location. <br />Noxious weeds inventoried (potential concern) within the Breeze Basin Pit are: <br />• Yellow Toadflax <br />• Leafy Spurge <br />• Tamarisk (Salt Cedar) <br />• Common Mullein <br />• Hoary Cress <br />• Musk Thistle <br />• Russian Olive <br />WEED CONTROL PRINCIPLES <br />An integrated approach to weed management is extremely important because no single <br />tool will do the entire job. Weed management results in highly effective weed control. <br />Principals of weed management are: <br />Prevention: Prevention of noxious weeds includes good land stewardship, planting <br />weed free seed, avoiding planting invasive species, using weed seed free mulch and <br />erosion control and using clean equipment. <br />Cultural practices: Cultural practices encourage competition from desirable plants <br />through dense seeding, fertilization, mulching, and improved land management <br />practices. <br />Chemical control: The sensible use of the proper herbicides at the optimum time can be <br />the most effective method of control for very persistent weeds. Not all herbicides are <br />equally effective on all weeds nor can every herbicide be used in every situation. A <br />licensed professional will perform application of herbicides. The following list identifies <br />the noxious weed species, preferred herbicide and recommended timing for application: <br />Typically two herbicide treatments occur throughout the year for noxious weeds. The <br />first application will occur in the spring, typically prior to May 15. The second application <br />Noxious Weed Management Plan 2 <br />
