placement in the proper seed box. Small seeded species ere broadcast from the small <br />seed box, while large seeded species ere drilled from the large seed box. All permanent <br />seedinge were completed in September. <br />No mulching activities were conducted during 1993. All permanently revegetated areas <br />received a cover crop of Re-green, a sterile hybrid Acroovron/winter wheat cross. The <br />cover crop seeding rate was 20 PLS pounds per acre. <br />Temporary revegetation was Conducted during 1993. Areas seeded included cut and fill <br />slopes of Heul Road G end topsoil Stockpiles HX end JJ. Seed Mix No. 4, the approved mix <br />for temporary stebilitetion of road cuts and topsoil stockpiles, was seeded in the fell of <br />7993. Seed Mix No. 4 is listed fn Table 93.4. Intermediate wheatgrass (Acroovron <br />in[ermedium) was dropped from the mix end alfalfa was reduced to 0.25 PLS lb per acre <br />(drilled rate). Broadcast seeding rates were double the drilled rate listed in Table <br />93.4. The tut and fill slopes on Heul Road G were broadcast seeded and the topsoil <br />stockpiles were combination drill and broadcast seeded. <br />Shrub planting during the 1993 season included establishment of a 0.2 acre live shrub clump <br />transplant area in the reconstructed drainage (see Exhibit 93.3). Approximamtely 30 clumps <br />were salvaged from adjacent native sites to be affected by ongoing mining operations. The <br />clumps were salvaged using a 988 front-end loader and transported to prepared sites in the <br />reclaimed area. Topsoil was placed around the transplanted clumps and the transplants were <br />"watered-in" from a water truck. The transplants were completed in the fall of 1993 after <br />the shrubs established dormancy. Principal transplanted species included serviceberry <br />(Amelanchier elnifolie), big sagebrush (Artemi sic tridentate), mountain snowberry <br />(SVmohoricaroos oreoohilus ), and associated grasses and fortis. <br />Monitorino. Revegetation monitoring was not conducted at the Seneca 11-W mine in 7993. <br />Weed Control. Survey of noxious weeds was carried out on the mine permit area during the <br />1993 field season. Veed control activities were conducted only along the mine entrance <br />road and near Pond 006. Canada thistle (Cirsium arvense) was the target species in control <br />areas. The applied herbicide consisted of a tank mix of 2.5 gallons of 22K Tordon and 0.5 <br />gallons of Banvel with 250 gallons of water. A spot spray gun was used to concentrate <br />• control activities on target areas. The herbicide mix, based on Colorado State Extension <br />Service recommendations was mixed and applied under the supervision of a certified <br />applicator. Yeed control areas will be monitored in 1994. <br />11 <br />
