RULE 4 PERFORMANCE STANDARDS <br />In the event individual components of the mix are unavailable, guidance from the Division <br />will be sought prior to implementation of the trial. Weedguard fabric or it's equivalent will <br />be placed in rows (at intervals of approximately 22 feet) and will be used to severely reduce <br />competition between the containerized plantings and annual weeds and grasses. Please see <br />the "Expected Field Implementation Plan for Aspen/Tall Shrub Field Trials" illustration <br />below. <br />e) Containerized 2-3 foot serviceberry and mahogany plants will utilized from the most <br />similar source elevation available in the region available. Based on the volume of <br />containerized plants included in the trial (550), and the expectations of success, a combined <br />number of (300) serviceberry and mahogony plants within the trial during 2016 (from seed <br />and live plantings) will be considered a successful demonstration of Coloywo's ability to <br />proceed further with additional plantings. Supplemental planting of serviceberry and <br />mahogony will be initiated in year 2012 should survival of the 2011 plantings be less than <br />350 stems/acre. Alternative methods for demonstrating compliance with the establishment <br />of Tall Shrub habitat in South Taylor will be initiated with the CPW during 2013, should <br />failure of this trial continue. <br />f) Containerized serviceberry and mountain mahogony plants will be placed through the <br />weed barrier by hand (or by mechanical means if practical and economically feasible) as <br />per best practices with regards to depth, etc. Proper planting holes are important in <br />transplant survival. Holes should be two to three times wider than the root ball. If the soil <br />is clay and the sides of the hole become glazed during digging, the sides of the hole should <br />be 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 />mountain mahogony planting densities will be one plant every four linear feet (1/2 <br />serviceberry, 1/2 mahogony) 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 the entire <br />trial 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 />Rule 4 Performance Standards 4-59 Revision Date: 5/25/18 <br />Revision No.: RN -07 <br />
