RULE 4 PERFORMANCE STANDARDS containerized plantings and annual weeds and grasses. Please see the "Expected Field Implementation Plan for Tall Shrub Field Trials" illustration below. e) Containerized 2-3 foot serviceberry and mahogany plants will be utilized from the most similar source elevation available in the region. Based on the volume of containerized plants included in the trial (550), a combined number of (300) serviceberry and mahogany plants within the trial (five years after implementation) will be considered a successful demonstration of Colowyo's ability to establish these species. Supplemental planting of serviceberry and mahogany should be initiated the year following initial trial establishment should initial survival of the plantings be very low. f) Containerized serviceberry and mahogany plants will be placed through the weed barrier fabric by hand (or by mechanical means if practical and economically feasible) as per best practices with regards to depth, etc. Proper planting holes are important in transplant survival. Holes should be two to three times wider than the root ball. If the soil is clay and the sides of the hole become glazed during digging, the sides of the hole should be roughened with a spade. Holes should be prewatered before planting in dry soils. This prevents initial postplant water from migrating away from the root ball. Every effort will be made to plant at the same depth that the tree or shrub was growing in its previous location. Damaged roots will be clean-cut with a sharp blade prior to planting. If any circling or kinked roots are discovered during the transplanting procedure, they will be severed to prevent future girdling of the plant. Every effort will be made to orient the tree or shrub in the same direction, relative to the sun, as it was facing in the previous location. Plantings will be performed in the fall by properly trained personnel. Serviceberry and mahogany planting densities will be one plant every four linear feet (1/2 serviceberry, 1/2 mahogany) within a row. g) Colowyo will place contour furrows immediately above approximately every third fabric row (approximately every 66 feet). The trial will exhibit alternating bands of modified Sagebrush Steppe mix (approximately 17 feet), fabric/containerized plantings (4-5 feet wide), modified Sagebrush Steppe mix (approximately 12 feet), contour furrow (approximately 5 feet). This pattern should allow for specific emphasis on containerized plantings establishment while minimizing the risk of excessive erosion during the period of early establishment of the trial area. h) An "elk proof' exclusionary fence will be erected around the perimeter of the trial area to protect it from ungulates immediately after planting activities are completed. i) In the event of stand failure the area will revert back to sagebrush steppe for the purposes of Phase III bond release in the future, and will be counted collectively with other sagebrush steppe areas to meet sample adequacy and reference area comparisons.
