• Field Trial Details. Field trial locations are given in Map 1 (sheet 2) of the Trapper Mine <br />Annual report document. The field plots are embodied in the F-AB-00 reclaimed parcel. <br />On the map the specific field trials as described below begin with 1 at the south end of <br />the reclaimed parcel and are numbered progressively northward. The seed mixtures <br />referenced below can be found in the CSU Shrub Establishment Study: Final Technical <br />Progress Report that is on file at the Division office. <br />1. 6 inches (15 cm) of live-haul topsoil over spoil with strip seeding. The strip <br />seeding included a strip of native shrubs and native low-competitive forbs that <br />alternated with a strip of native grasses, forbs, and shrubs. The seed mixtures for <br />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. <br />1 above. <br />3. 6 inches (15 cm) of live haul topsoil over spoil and seeded with native shrubs and <br />low-competitive native forbs. Surface manipulations included to enhance soil <br />moisture conditions. The seed mixture for this treatment is presented in Table 1. <br />4. Non-topsoiled spoil seeded with relatively unpalatable native shrubs, low- <br />competitive native forbs, and low-competitive native grasses. See Table 3 for the <br />seed mixture used in this treatment. <br />• 5. Non-topsoiled spoil, strip seeded as described in No. 1 above. <br />6. This treatment consists of the current reclamation approach. Topsoil depth and <br />seed mixture represent the approach carried out for reclamation in 2000. <br />Monitoring was conducted each year from 2001 through 2004 by CSU and results were <br />provided each of those years. A final project report will be completed in June 2005. The <br />final report will detail the shrub establishment results by treatment method and provide a <br />detailed summary of suggested reclamation methods for promoting shrub establishment. <br />In the interest of determining long-term results, Trapper and DMG intend to continue <br />monitoring the plots at regular intervals. Trapper will continue to maintain the field trial <br />sites until such time as it is felt the field plots can no longer provide meaningful <br />information. <br />• <br />4-125 <br />RPIVIS!Gn: <br />A O __ <br />APPROVED MAY 2 7 2005
