Seneca Mine <br />The test plots at Seneca are located adjacent to each other in one contiguous block in the Wadge <br />Pit azea (UTM 13T 322555 4476182) at an average elevation of 7600 feet. The selected site for the test <br />plots has an east aspect. Each treatment measures l00 feet by 100 feet (Figure 4). A description of each <br />treatment is presented below. It should be noted that one treatment originally proposed was modified. <br />The proposed treatment of no topsoil with seeding and transplanting was replaced with a treatment of no <br />topsoil and transplanting, without the seeding. Species of transplants used were boxelder maple, <br />Saskatoon serviceberry, black chokecherry, Gamble oak, Wood's rose, skunkbush sumac and mountain <br />snowberry. All shrub transplants used at the Seneca demonstration plots were grown from local seed <br />sources by Bitterroot Restoration, Inc. and were inoculated with a local soil community to facilitate the <br />establishment of appropriate root microsymbionts. <br />1. 6 inches (15 cm) of stockpiled topsoil over spoil and native shmb transplants as tubelings. <br />Surface manipulation incorporated to reduce run off. This treatment is represented by one <br />unfenced 100- x 100-ft plots. <br />2. 20 inches (50 cm) of stockpiled topsoil over spoil and native shrub transplants as tubelings. <br />Surface manipulation incorporated to reduce mn off. This treatment is represented by one fenced <br />and one unfenced 100- x 100-ft plots. <br />3. 20 inches (50 cm) of stockpiled topsoil over spoil with strip seeding. The strip seeding included a <br />strip of native shmbs and native low-competitive forbs that altemated with a strip of native <br />grasses, forbs, and shrubs. The seed mixtures for this treatment are presented in Tables 4 and 5. <br />This treatment is represented by one fenced 100- x 100-ft plot. <br />4. Non-topsoiled spoil with native shrub transplants as tubelings. Surface manipulation incorporated <br />to reduce run off. This treatment is represented by one fenced and one unfenced 100- x 100-ft <br />plots. <br />5. 6 inches (I S cm) of stockpiled topsoil over spoil with strip seeding. The strip seeding included a <br />strip of nafive shmbs and native low-competitive forbs alternated with a strip of native grasses, <br />forbs, and shmbs. The seed mixtures for this treatment are presented in Tables 4 and 5. This <br />treatment is represented by one fenced and one unfenced 100- x ] 00-ft plots. <br />6. Non-topsoiled spoil with strip seeding. The strip seeding included a strip of native shrubs and <br />native low~ompefitive forbs altemated with a strip of native grasses, forbs, and shrubs. The seed <br />mixtures for this treatment are presented in Tables 4 and 5. No transplants. This treatment is <br />represented by one unfenced 100- x 200-ft plot. <br />Seeding and transplanting of the test plots was completed in November 2000. Transplants <br />(tubelings) were planted at a rate of one per 20 square ft or a 4 ft by 5 ft pattern. Transplanted species <br />included Acer negwulo, Amelanchier alnifolia, Prunus virginiana, Quercas gambelli, Symphoricarpos <br />oereophilus, and Rosa woodsii. Not all of these species were planted in each plot and no records were <br />made for species planted or numbers for each plot. Fencing of the study was completed in the spring of <br />2001. The fence was installed in such a fashion that treatments 2, 4 and 5 have fenced and unfenced <br />plots. <br />• <br />
