Supplemental planting of serviceberry and chokecherry <br /> will be initiated in year 2012 should survival of the 2011 plantings be less than 350 <br /> stems/acre. Alternative methods for demonstrating compliance with the establishment of <br /> Tall Shrub habitat in South Taylor will be initiated with the Colorado Division of Wildlife <br /> during 2013, should failure of this trial continue. <br /> f) Containerized serviceberry and chokecherry plants will be placed through the weed <br /> barrier by hand(or by mechanical means if practical and economically feasible)as per best <br /> practices with regards to depth, etc. Proper planting holes are important in transplant <br /> survival. Holes should be two to three times wider than the root ball. If the soil is clay and <br /> the sides of the hole become glazed during digging, the sides of the hole should be <br /> roughened with a spade. Holes should be prewatered before planting in dry soils. This <br /> prevents initial postplant water from migrating away from the root ball. Every effort will <br /> be made to plant at the same depth that the tree or shrub was growing in its previous <br /> location. Damaged roots will be clean-cut with a sharp blade prior to planting. If any <br /> circling or kinked roots are discovered during the transplanting procedure, they will be <br /> severed to prevent future girdling of the plant. Every effort will be made to orient the tree <br /> or shrub in the same direction,relative to the sun, as it was facing in the previous location. <br /> Plantings will be performed in the fall by properly trained personnel. Serviceberry and <br /> chokecherry planting densities will be one plant every four linear feet (1/2 serviceberry, <br /> 1/2 chokecherry) within a row. <br /> g) Colowyo will place contour furrows immediately above approximately every third <br /> fabric row (approximately every 66 feet). The trial will exhibit alternating bands of <br /> modified Sagebrush Steppe mix(approximately 17 feet), fabric/containerized plantings(4- <br /> 5 feet wide),modified Sagebrush Steppe mix(approximately 17 feet), fabric/containerized <br /> plantings (4-5 feet), modified Sagebrush Steppe mix (approximately 12 feet) contour <br /> furrow (approximately 5 feet). This pattern should allow for specific emphasis on <br /> containerized plantings establishment while minimizing the risk of excessive erosion <br /> during the period of early establishment of the trial area. <br /> h) An "elk proof' exclusionary fence will be erected around the perimeter of entire trial <br /> area to protect it from ungulates. <br /> i) In the event of stand failure the area will revert back to sagebrush steppe for purposes <br /> of Phase III bond release in the future, with the exception that the requirement for 50% of <br /> the required 375 shrubs in this area be big sagebrush(Section 4.15.8),this requirement will <br /> reasonably be dropped, due to the reduction in sagebrush seed included in the mix applied. <br /> 3) Colowyo agrees to establish one small (one acre)tall shrub establishment site with thin topsoil <br /> conditions. The location of this area will be in the immediate proximity of the South Taylor X <br /> coal pod as portrayed below and on Map 28B. The location for this trial represents elevation and <br /> aspect characteristics that are very similar to the majority of the tall shrub areas disturbed in the <br /> South Taylor area. Slope characteristics are more moderate than the areas disturbed, but for <br /> purposes of implementing and monitoring this trial it was determined essential that access and <br /> stability of the test location be manageable. Actual results from the trial should yield information <br /> that can be used to apply additional stability and/or sediment control measures on larger areas if <br /> this attempt is successful. <br /> a) The area will be regraded in accordance with PMT requirements. Additional ripping of <br /> the overburden material will be conducted by a dozer to a depth of approximately tour feet <br /> Rule 4 Performance Standards 4-57 Revision Date: 1/22/20 <br /> Revision No.: TR-136 <br />
