direction, relative to the slut, as it was facing in the previous location. <br />Plantings will be performed in the fall by properly trained personnel.. <br />Serviceberry and chokecherry planting densities will be one plant every four <br />linear feet (1/2 serviceberry, 1/2 chokecherry) within a row. <br />g) Colowyo will place contour furrows immediately above approximately every <br />third fabric row (approximately every 66 feet). The trial will exhibit <br />alternating bands of modified Sagebrush Steppe mix (approximately 17 feet), <br />fabric /containerized plantings (4 -5 feet wide), modified Sagebrush Steppe mix <br />(approximately 17 feet), fabric /containerized plantings (4 -5 feet), modified <br />Sagebrush Steppe mix (approximately 12 feet) contour furrow (approximately <br />5 feet). This pattern should allow for specific emphasis on containerized <br />plantings establishment while minimizing the risk of excessive erosion during <br />the period of early establishment of the trial area. <br />h) An "elk proof' exclusionary fence will be erected around the perimeter of <br />entire trial area to protect it from ungulates. <br />i) In the event of stand failure the area will revert back to sagebrush steppe for <br />purposes of Phase III bond release in the future, with the exception that the <br />requirement for 50% of the required 375 shrubs in this area be big sagebrush <br />(Section 4.15.8), this requirement will reasonably be dropped, due to the <br />reduction in sagebrush seed included in the mix applied. <br />3) Colowyo agrees to establish one small (one acre) tall shrub establishment site <br />with thin topsoil conditions. The location of this area will be in the immediate proximity <br />of the South Taylor X coal pod as portrayed below and on Map 28B. The location for <br />this trial represents elevation and aspect characteristics that are very similar to the <br />majority of the tall shrub areas disturbed in the South Taylor area. Slope characteristics <br />are more moderate than the areas disturbed, but for purposes of implementing and <br />monitoring this trial it was determined essential that access and stability of the test <br />location be manageable. Actual results from the trial should yield information that can be <br />used to apply additional stability and /or sediment control measures on larger areas if this <br />attempt is successful. <br />a) The area will be regraded in accordance with PMT requirements. Additional <br />ripping of the overburden material will be conducted by a dozer to a depth of <br />approximately four feet to ensure the material is in a loose, rough condition to <br />encourage infiltration of rain/snowmelt and root development. Overburden <br />with a significant coarse fragment component is desireable. <br />b) The area will be tested for overburden suitability as per requirements. <br />c) An approximate average of four inches of topsoil will be placed to replicate <br />common topsoil depth conditions in the surrounding area in stands of this <br />nature. Once the topsoil has been placed, it will be roughened with a disc <br />(pulled by a dozer or other appropriate machine) to ensure the material is in a <br />loose, rough condition to encourage infiltration of rain/snowmelt and root <br />development. <br />d) The Sagebrush Steppe mix has been modified to reduce the volume of "low <br />shrubs" in favor of tall shrub components of the mix. The grasses currently <br />included in the mix were reduced to minimize competition, while still <br />4.15 -16 Revision Date: 6/21/11 <br />Revision No.: TR -84 <br />
