• growing. Spraying will be done by use of a backpack spray system or an ATV <br />mounted spray tank. Canada Thistle should be sprayed in the spring, prior to <br />bud stage. <br />Russian Knapweed will be sprayed with Curtail, 3 quarts/acre mixed with a <br />non-ionic surfactant at 1 quart per 100 gallons. It will not be applied when spray <br />particles may be carried by air currents to areas where desirable plants are <br />growing. Spraying will be done by use of a backpack spray system or an ATV <br />mounted spray tank. Russian Knapweed should be treated in the Spring, prior to <br />bud stage. <br />Tamarisk and Russian Olive are on Montrose County's Noxious weed list, <br />but not included in the current plan for management. At the request of the DMG, <br />a Tamarisk control plan follows. <br />The Operator will initiate Tamarisk control in permanently regraded and <br />seeded areas beginning in the fall of 2006. Tamarisk will be controlled by <br />mechanical removal or by cutting the stem and applying herbicide (known as the <br />cut-stump method). Individual tamarisk plants will be cut as close to the ground <br />as possible and herbicide will be applied immediately thereafter to the perimeters <br />of the cut stems. The herbicides used will be triclopyr (e.g. Garlon4 or <br />• Pathfinderll) or glyphosate (Rodeo). Fall treatments are believed to be most <br />effective because the plants are translocating materials to their roots. <br />The operator commits to performing aggressive weed control during the <br />operations and reclamation phases of the operation. <br />Pest control may be necessary if infestations seriously impact the <br />reclaimed area. The current Colorado Pesticide Guide from the Colorado State <br />University, Cooperative Extension Service will be consulted in order to determine <br />the proper pesticide to be used. Prairie dogs can become a serious detriment to <br />the establishment and maintenance of desirable vegetation. If prairie dog <br />infestations become a serious problem in the reclaimed areas, an appropriate <br />mitigation plan will be developed in consultation with the Division and the <br />appropriate State and Federal wildlife agencies. <br />RECLAMATION SUCCESS: <br />Reclamation success will be qualitatively evaluated during routine <br />inspections of the reclaimed sites. These evaluations shall include assessments <br />of noxious weeds, species diversity and the general health of the vegetation. <br />Results of these evaluations will be included in the annual reclamation reports <br />required under Rule 2.04.13. <br />t~J <br />2.05-25(i) 03/06 <br />
