stability of the test location be manageable. Actual results from the trial should yield <br />• information that can be used to apply additional stability and/or sediment control <br />measures on larger areas if this attempt is successful. <br />a) <br />The area will be regraded in accordance with PMT requirements. <br />b) <br />The area will be tested for overburden suitability as per requirements. <br />c) <br />At least 48 inches of topsoil will be placed to replicate common topsoil depth <br />conditions in the surrounding area in stands of this nature. Once the topsoil <br />has been placed, it will be cross - ripped with a dozer or by other appropriate <br />means to ensure the material is in a loose, rough condition to encourage <br />infiltration of rain/snowmelt and root development. <br />d) <br />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 also reduced to minimize competition, while still <br />providing some soil stabilization function. The entire trial area will be seeded <br />with the modified Sagebrush Steppe Mix as seen below. In the event <br />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 <br />equivalent will be placed in rows (at intervals of approximately 22 feet) and <br />will be used to severely reduce competition between the containerized <br />plantings and annual weeds and grasses. Please see the "Expected Field <br />Implementation Plan for Aspen/Tall Shrub Field Trials" illustration below. <br />e) <br />Containerized 2 -3 foot serviceberry and chokecherry plants will utilized from <br />the most similar source elevation available in the region. Based on the volume <br />• <br />of containerized plants included in the trial (550), and the expectations of <br />success, a combined number of (300) serviceberry and chokecherry plants <br />within the trial during 2016 (from seed and live plantings) will be considered <br />a successful demonstration of Coloywo's ability to proceed further with <br />additional plantings. Supplemental planting of serviceberry and chokecherry <br />will be initiated in year 2012 should survival of the 2011 plantings be less <br />than 350 stems /acre. Alternative methods for demonstrating compliance with <br />the establishment of Tall Shrub habitat in South Taylor will be initiated with <br />the Colorado Division of Wildlife during 2013, should failure of this trial <br />continue. <br />f) <br />Containerized serviceberry and chokecherry plants will be placed through the <br />weed barrier by hand (or by mechanical means if practical and economically <br />feasible) as per best practices with regards to depth, etc. Proper planting holes <br />are important in transplant survival. Holes should be two to three times wider <br />than the root ball. If the soil is clay and the sides of the hole become glazed <br />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 <br />postplant water from migrating away from the root ball. Every effort will be <br />made to plant at the same depth that the tree or shrub was growing in its <br />previous location. Damaged roots will be clean -cut with a sharp blade prior to <br />planting. If any circling or kinked roots are discovered during the <br />transplanting procedure, they will be severed to prevent future girdling of the <br />• <br />plant. Every effort will be made to orient the tree or :shrub in the same <br />4.15 -15 Revision Date: 6/21/11 <br />Revision No.: TR -84 <br />
