2 <br />availability and other factors. Of prime importance to changing seed. mixtures and rates will be the evaluation of <br />initial revegetation success. <br />Land Management <br />Noxious Plant Control <br />Mine disturbed areas will be monitored for infestations of Noxious Weeds, including Scotch and musk thistle, <br />Canadian thistle, hounds tongue, and loco weed. <br />Whenever practical, mechanical control (cutting, tilling, grazing, etc) will be the control of preference. At adjacent <br />mine sites, mechanical control of hounds tongue, loco weed. and Scotch and musk thistle has been found to be <br />effective. <br />More aggressive infestations have been effectively controlled with Roundup mixed @ 2.66 oz. per gallon of water, <br />applied directly on the plant. As this is a non - restricted pesticide /herbicide, Roundup will be the preferred method of <br />chemical control for annual and biannual thistle infestations. <br />Mechanical control of Canadian thistle, a perennial, generally is ineffective. Thus, Canadian thistle will be <br />controlled by an application of either Milestone, Banvel (dicamba) or a combination of 0.5 qt. Banvel plus 1.0 qt. of <br />2,4 -D where Banvel alone proves ineffective. <br />The following table provides a list of target noxious weeds and Dr. Beck's (CSU) recommended herbicide. <br />Noxious Weed <br />Herbicide <br />African rue Class A weed <br />Polaris <br />Diffuse kna weed <br />Milestone <br />Russian kna weed <br />Milestone <br />Spotted kna weed <br />Milestone <br />Leafy sure <br />Tordon <br />Dalmatian toadflax <br />Milestone <br />Yellow toadflax <br />Tordon <br />Musk thistle <br />Milestone <br />Scotch Thistle <br />Milestone <br />Canadian Thistle <br />Milestone <br />Hounds tongue <br />Milestone <br />Livestock Grazing Controls <br />Livestock grazing will be restricted during operations and the reclamation liability period. Timing of grazing will be <br />determined jointly by LCC and the CDMG. Livestock damage to revegetation will be controlled as necessary by <br />selective fencing or other management techniques. Normal range management practices will be used as necessary to <br />enhance the value of revegetated areas. <br />Revegetation Success Criteria <br />Revegetation success will be based on the comparison of revegetated communities to corresponding unmined <br />reference area communities. LCC will utilize an extended reference area (ERA) approach comprised of undisturbed <br />areas within the intensive vegetation baseline inventory area. Map 2.04.10 -1 shows the disturbed areas <br />superimposed on the vegetation community type map. Designated undisturbed areas form the ERA for Oak/Pinion <br />and grassland extended reference areas. Potential ERA's for Hay Meadow vegetation communities are being <br />investigated. The selected area will be indicated on Map 2.04.10 -1 subject to evaluation and landowner consent. <br />TR -17 2.05 -71 06/12 <br />
