diameter, available within the specified spacing distance, on the southwest side of the tree. <br /> Where possible, these materials will be placed within one inch (1") of the tree, except where <br /> larger pieces will provide protection when placed further away. When round material is <br /> used, it shall be placed in a manner which prevents it from rolling. Transportable material <br /> will never be placed on the uphill side of the tree. Should transportable or stationary <br /> material not be available, the tree shall still be planted. <br /> d. Before constructing the planting hole, CONTRACTOR shall clear the planting spot of all �7< c • <br /> limbs, logs, bark, rotten wood, rock and loose debris and shall scalp duff, sod, living plants, <br /> roots and other material unsuitable for tree growth, in order to expose bare ground. <br /> Minimum scalping diameter for each planting spot is eighteen inches (18"). <br /> e. Hole opening shall be determined to be feasible where PROJECT MANAGER can find a <br /> plantable spot in three (3) attempts within the spacing requirement, and where a hole can be <br /> opened in the planting spot in five (5) or less attempts with the hand tool. <br /> Hole Construction, Tree Placement, Hole Filling, Species Mixing <br /> a. The hole shall be located at the center of the scalped area. <br /> b. An open hole, broken out on three (3) sides, and deep and wide enough to fully <br /> accommodate the roots of the tree plus a small volume (approximately 0.1 ounce) of <br /> hydrated Polyaccrylimide is required. The opening of a hole without breaking it out on <br /> three (3) sides shall not be permitted. <br /> c. The trees shall be planted in the center of the prepared hole, deep enough so that the <br /> hydrated Polyaccrylimide can be accommodated at the base of the hole, and one half <br /> inch (1/2") of soil can be placed on top of the plug, level with the surrounding soil <br /> surface, to seal the plug into the ground. Plug growing media shall not be distorted or <br /> broken from the root system during the planting process. If the media is broken, the <br /> tree shall be planted as described herein, ensuring that the exposed roots are not <br /> doubled up, twisted, spiraled, bunched,jammed or compressed in the planting hole. <br /> d. Soil shall be filled in and firmed around the plugs. Rock shall be kept out of the holes. <br /> Soil shall be filled in and firmed progressively so no loose soil or air pockets remain, and <br /> tree is as firmly planted as soil conditions allow. Firming of the soil shall be done so that <br /> tree and root systems are not damaged. After planting, the tree stem shall be erect and <br /> free to grow. The tree shall not be weighted down with mud or debris. Firming soil with <br /> the heel of the foot is not permitted. <br /> e. Mixing of species is elevation dependent. Sub Alpine Fir will only be planted uphill from <br /> the Lamp House. <br /> Inspection and Acceptance <br /> Inspection <br /> PROJECT MANAGER will inspect planting to determine adherence to these specifications, and <br /> as the basis for computing the rate of payment. Inspections will consist of observations of tree <br /> handling, site preparation, planting procedures and examinations of individual trees at randomly <br /> 8 <br />
