RULE 4 PERFORMANCE STANDARDS <br />included in the trial (550), and the expectations of success, a combined number of (300) <br />serviceberry and mahogony plants within the trial during 2016 (from seed and live plantings) will <br />be considered a successful demonstration of Coloywo's ability to proceed further with additional <br />plantings. Supplemental planting of serviceberry and mahogony will be initiated in year 2012 <br />should survival of the 2011 plantings be less than 350 stems/acre. Alternative methods for <br />demonstrating compliance with the establishment of Tall Shrub habitat in South Taylor will be <br />initiated with the Colorado Division of Wildlife during 2013, should failure of this trial continue. <br />f) Containerized serviceberry and mountain mahogony 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 survival. <br />Holes should be two to three times wider than the root ball. If the soil is clay and the sides of the <br />hole become glazed during digging, the sides of the hole should be roughened with a spade. Holes <br />should be prewatered before planting in dry soils. This prevents initial postplant water from <br />migrating away from the root ball. Every effort will be made to plant at the same depth that the <br />tree or shrub was growing in its previous location. Damaged roots will be clean-cut with a sharp <br />blade prior to planting. If any circling or kinked roots are discovered during the transplanting <br />procedure, they will be severed to prevent future girdling of the plant. Every effort will be made <br />to orient the tree or shrub in the same direction, relative to the sun, as it was facing in the previous <br />location. Plantings will be performed in the fall by properly trained personnel. Serviceberry and <br />mountain mahogony planting densities will be one plant every four linear feet (1/2 serviceberry, <br />1/2 mahogony) within a row. <br />g) Colowyo will place contour furrows immediately above approximately every third fabric row <br />(approximately every 66 feet). The trial will exhibit alternating bands of modified Sagebrush <br />Steppe mix (approximately 17 feet), fabric/containerized plantings (4-5 feet wide), modified <br />Sagebrush Steppe mix (approximately 17 feet), fabric/containerized plantings (4-5 feet), modified <br />Sagebrush Steppe mix (approximately 12 feet) contour furrow (approximately 5 feet). This <br />pattern should allow for specific emphasis on containerized plantings establishment while <br />minimizing the risk of excessive erosion during the period of early establishment of the trial area. <br />h) An "elk proof' exclusionary fence will be erected around the perimeter of the entire trial area <br />to protect it from ungulates. <br />i) In the event of stand failure the area will revert back to sagebrush steppe for purposes of Phase <br />III bond release in the future, with the exception that the requirement for 50% of the required 375 <br />shrubs in this area be big sagebrush (Section 4.15.8), this requirement will reasonably be dropped, <br />due to the reduction in sagebrush seed included in the mix applied. <br />Rule 4 Performance Standards 4-52 Revision Date: 1/31/18 <br />Revision No.: TR -119 <br />
