0 Trapper Mine <br />The test plots at Trapper are located in the F pit backfill area (UTM 13T 282979 4478354) at an average <br />elevation of 7200 feet. The selected site for the test plots has a north aspect. The plots are located adjacent to <br />each other in one contiguous block. Each treatment measures 180 ft wide and 363 ft long (Figure 3). A <br />description of each treatment is presented below. <br />1. 6 inches (15 cm) of live-haul topsoil over spoil with strip seeding. The strip seeding included a strip <br />of native shrubs and native low-competitive forbs that alternated with a strip of native grasses, forbs, and <br />shrubs. The seed mixtures for this treatment are presented in Tables 1 and 2. <br />2. 20 inches (46 cm) of live-haul topsoil over spoil, strip seeded as described in No. 1 above. <br />3. 6 inches (15 cm) of live haul topsoil over spoil and seeded with native shrubs and low competitive <br />native forbs. Surface manipulations included to enhance soil moisture conditions. The seed mixture for <br />this treatment is presented in Table 1. <br />4. Non-topsoiled spoil seeded with relatively unpalatable native shrubs, low-competitive native forbs, <br />and low-competitive native grasses. See Table 3 for the seed mixture used in this treatment. <br />5. Non-topsoiled spoil, strip seeded as described in No. 1 above. <br />Test plot construction was completed in November 2000. Unfavorable weather prevented seeding in the fall <br />of 2000, so plots were seeded in April, 2001. Fencing of half the study area was completed in the spring of <br />2002. Commercial mycorrhizal inoculum was applied to 1.5-m wide strips in each plot at Trapper Mine in <br />order to evaluate the potential for such a treatment to improve shrub establishment. This inoculation <br />treatment was applied in May, 2001 by Trapper Mine personnel. <br />Figure 3. Shrub establishment demonstration plots at Trapper mine. <br />Seneca Mine <br />The test plots at Seneca are located adjacent to each other in one contiguous block in the Wadge Pit area <br />(UTM 13T 322555 4476182) at an average elevation of 7600 feet. The selected site for the test plots has an <br />east aspect. Each treatment measures 100 feet by 100 feet (Figure 4). A description of each treatment is <br />presented below. It should be noted that one treatment originally proposed was modified. The proposed <br />treatment of no topsoil with seeding and transplanting was replaced with a treatment of no topsoil and <br />transplanting, without the seeding. Species of transplants used were boxelder maple, Saskatoon serviceberry, <br />black chokecherry, Gamble oak, Wood's rose, skunkbush sumac and mountain snowberry. All shrub <br />transplants used at the Seneca demonstration plots were grown from local seed sources by Bitterroot <br />Restoration, Inc. and were inoculated with a local soil community to facilitate the establishment of <br />appropriate root microsymbionts. <br />1. 6 inches (15 cm) of stockpiled topsoil over spoil and native shrub transplants as tubelings. Surface <br />manipulation incorporated to reduce run off. This treatment is represented by one unfenced 100- x 100-ft <br />plots. <br />2. 20 inches (50 cm) of stockpiled topsoil over spoil and native shrub transplants as tubelings. Surface <br />manipulation incorporated to reduce run off. This treatment is represented by one fenced and one <br />unfenced 100- x 100-ft plots.
