On drilled sites the hay or straw will be crimped with a serrated disc or <br />other appropriate equipment. On steeper slopes and areas where crimping <br />is not feasible, straw or hay will be anchored down using a tackifier, <br />netting, or a tackifier mixed with wood or wood/paper fiber. The tackifier <br />will be applied in accordance with manufacturer's specifications with <br />consideration of the type and quantity of mulch applied, slope, soil <br />conditions and other applicable factors. <br />(v) No irrigation or disease control measures are planned at this time. Pest <br />control will primarily involve control of noxious weeds. The noxious <br />weeds that have been identified on site are White Top, Russian Knapweed <br />and Tamarisk. If noxious weed infestations occur at levels which may <br />interfere with successful revegetation or are detrimental to stand quality, <br />weed control using herbicides will be implemented. White Top and <br />Russian Knapweed will be sprayed with G4~rtail, 2.0 oz/gallon. It will not <br />be applied when spray particles maybe carried by air currents to areas <br />where desirable plants are growing. Russian knapweed should be sprayed <br />in the spring and fall. White Top must be sprayed in early spring. Spraying <br />will be done by use of a backpack spray system or an ATV mounted spray <br />tank <br />Vegetation at the North Decline is dominated by cheatgrass to the <br />detriment of other more desirable grasses. During the fall of 2005 <br />cheatgrass at the North Decline was treated with a mix of 6 ounces of <br />Plateau and 2 ounces of Roundup per acre. During the fall of 2006 it was <br />re-treated with Plateau at the rate of 6 ounces per acre. In February of 2007 <br />the treated areas were interseeded with the seedmix presented on Table 14- <br />14. The soil was scarified by using an ATV mounted spike tooth borrow <br />to ensure minimal damage to the mature shrub overstory. <br />The Operator intends to initiate Tamarisk control in permanently regraded <br />and seeded areas beginning in the fall of 2005. Tamarisk control will <br />begin at the south end of overland conveyor corridor, west of the river. <br />During ensuing years, the Operator will carry out a modest Tamarisk <br />control program. Tamarisk will be controlled by mechanical removal or <br />by cutting the stem and applying herbicide (known as the cut-stump <br />method). Individual tamarisk plants will be cut as close to the ground as <br />possible and herbicide will be applied immediately thereafter to the <br />perimeters of the cut stems. The herbicides used will be triclopyr (e.g. <br />Garlon4 or PathfinderIl) or imazapyr (Arsenal). Fall treatments are <br />believed to be most effective because the plants are translocating materials <br />to their roots. <br />14-17 (Rev. 10/07) <br />
