The goal of the project is to plant 200 trees per acre on approximately 28 acres. <br /> Trees will be planted in a random pattern by using a 'hoe dad' or similar tool to excavate an <br /> approximately twelve inch deep hole in the soil. A seedling previously soaked in water <br /> containing polyacrylamide, a root stimulator, will be placed roots first into the hole. Soil will <br /> be packed around the roots of the seedlings. A small water containment berm, eighteen inches <br /> in circumference and six inches in height, will be constructed around each seedling. A small <br /> sun shade, such as a piece of cedar shake, will be placed on edge on the south side of each <br /> seedling to provide shade. It is estimated that each corps member can plant 20 seedlings per <br /> hour. Access to the vicinity of each mine bench will be by vehicle. <br /> The tree and shrub planting portion of the project will be completed at the base of four of the <br /> five mine bench outslopes. The purpose of this phase of the project is to slow water draining <br /> from the outslopes, and to retain sediment which is transported by the runoff. Approximately <br /> fifteen acres will be impacted by this project. Access to these areas will be involve travel by <br /> foot. It is anticipated that 300 seedling trees will be planted per acre using the techniques <br /> described above. Additionally, 300 shrubs per acre will be planted in a random pattern to <br /> compliment the tree planting. These will be planted in a similar manner as the trees, except that <br /> the hole will be nine inches in depth, and that a sun shade is not necessary. <br /> Erosion Control Structures <br /> The erosion control structures will be constructed within existing gullies which generally have <br /> formed as a result of road drainage problems. Three simple, yet effective erosion control and <br /> sediment containment techniques will be employed. <br /> 1) In some areas, rock sediment traps will be constructed in the gullies. A trench <br /> approximately eighteen inches wide and nine inches deep will be hand dug perpendicular to the <br /> orientation of the gully from crest to crest. Rocks large enough to fill the trench will be placed <br /> within the trench to act as a foundation. Smaller rock will be stacked on and against the <br /> foundation rock, filling the gully from side to side, to an average height and thickness of two <br /> feet. <br /> 2) Another technique which will be used is the construction of sediment control structures built <br /> from logs. Corps Members will fell nearby aspen trees and choke the gullies with the trees. <br /> To do this, a trench approximately eighteen inches wide and nine inches deep will be hand dug <br /> perpendicular to the orientation of the gully from crest to crest. Logs will be cut so that they <br /> fit inside the trench, and from side to side within the gully. Logs will be cut and placed within <br /> the gully in a pyramidal shape to a height of about two feet and a basal width of at least three <br /> feet. The branches and limbs will be cut and placed upstream of the log dam. <br /> 3) In areas where there is sufficient subsurface water occurring within a gully, live transplanting <br /> of indigenous shrubs will take place. Areas suitable for live transplanting will be identified by <br /> the Project Manger. Crew Members will cut shrubs, such as willows, to a specified length. <br /> 6 <br />
