A description of results achieved: Excerpts below are from the attached Cedar Creek report; During 2008 partial reclamation of the ROM area was performed. The 2008 reclamation consisted of returning portions of the disturbed area backto approximate original contours and hydro seeding with a permanent seed mix and wood fiber mulch. During 2017, the run of mine pond was removed and the area was hydro seeded with permanent seed mix. Vegetation has flourished since initial reclamation efforts in 2008 & 2017 and passed all success criteria in 2019 and 2020. The ROM unit surpassed the total plant cover success criterion of >_36% (90% of the technical standard of 40%) with 68.8% in 2019 and 51.6% in 2020 (chart 5 in attached Cedar Creek report). The annual (total) herbaceous production success criterion of >_ 360 pounds per acre (90% of the technical standard value of 400 pounds per acre) was surpassed with 1,141 pounds per acre in 2019 and 951 in 2020 (Chart 6 in attached Cedar Creek report). A total of 320 trees, shrubs, and sub -shrubs per acre were sampled in 2019 which equates to a80% confidence limit of 131 that surpasses 90% of the technical standard when the reverse null ranked "L" test is utilized (Chart 7 in attached Cedar Creek report). A total of 332 trees, shrubs, and sub - shrubs per acre we sampled in 2020 surpassing the woody plant density success criterion of 90 per acre (90% of the technical standard value of 100 woody plants per acre). The ROM surpasses the diversity standard with the required number of total native or introduced perennial herbaceous species with between 0.5% and 60.0% relative cover (>_ five species) with six in 2019 and eight in 2020 (Chart 8 in attached Cedar Creek report). The total native perennial cool - season grasses with between 0.5% and 60.0% relative cover (>_ three species) was surpassed with four in 2019 and five in 2020 (Chart 9 in attached Cedar Creek report). The total native or introduced forb species with between 0.5% and 60% relative cover was (>_ two species) was met with two in 2019 and three in 2020 (Chart 10 in attached Cedar Creek report). And finally, the total number of native trees, shrubs and sub -shrubs with <80% relative cover (>_ two species) was surpassed with seven in 2019 and four in 2020.
