Pikeview Quarry Envirortmental Assessment Page 18 ' <br />l <br />l <br />l <br />f <br />p <br />anting wil <br />be <br />o <br />lowed by an initial watering and an earthen betm will be formed <br />around each seedling to collect and hold moisture. Site preparation prior to planting will <br />include clearing an azea roughly 3 feet by 3 feet, placing an anchored, fabric weed <br />barrier over the cleazed area and planting the seedling in the center of the cleared area. <br />Once the seedlings have been planted, each seedling will be protected with a mesh tree <br />guard. Polyacrylamides may be used to reduce competition from grasses and minimize , <br />moisture fluctuations <br />13. Tree planting on private lands <br />a) Seedling trees would be planted on the slopes below the cliffs. <br />b j Ponderosa pine and Douglas fir would be planted on the 2: ] slopes and concentrated <br />along the northern exposures of each ridge. This procedure would extend the <br />appeazance of normal tree growth pattern ofnorth-facing slopes down below the cliffs. ' <br />100 trees per surface acre would be planted in a random pattern, achieving 80% cover <br />for the mattare trees, assuming a 70% survival rate6. This planting area would taper from <br />full half-ridge width below the last cliff, to almost no trees at the 7,350' elevation. This ' <br />would mimic the natrowing of trees declining down the north side of a ravine. No <br />irrigation systems would be installed. Weed control fabric, moisture collection basins, <br />and polyacrylamides may be used to reduce competition from grasses and minimize <br />moisture fluctuations. <br />c) Rocky Mountain junipers would be planted on the reclaimed slopes below the cliffs, <br />thus mimicking the tree pattern on the south-facing slopes above the disturbed areas. <br />The number of planted trees per surface acre would vary from 60 trees on the three <br />slopes below the cliffs to 30 trees from elevation 7450' to 7250'. This planting pattern <br />would achieve a 20% cover assuming a 70% survival rate. <br />d) The enhancement of the reclamation effort in private land would occur in the later stages ' <br />of the reclamation process. Additional tree, shrub, or wildflower planting would occur <br />allowing for the increase of the random nattrre of the reclamation. Also, it would <br />provide some additional erosion control. Wildflower planting will exclude ox-eye daisy, ' <br />dames rocket and other weeds often included in "wildflower" mixes. <br />6 Success rates indicated in this environmental assessment refer to Forest Service standard guidelines and long term goals <br />for revegetation. Continuing monitoring will ensure that the best available practices are properly adopted to guarantee the <br />achievement of those goals. <br />~ "'Crou6lesome Weeds of the Rocky Mountain West" published by the Colorado Weed Management Association excludes <br />the use of these species. <br />Hydrosphere Resource Consultants, 1002 Walnut Sveet Suite 200, Boulder, CO 80302 <br />l_J <br /> <br />1 <br /> <br /> <br /> <br />
