Keenesburg Mine 2018 Vegetation Monitoring Report <br />Table 19: Reclamation Area 30 Succecc C'ritPria <br />6.2.3 Reclamation Area 31 <br />Reclamation Area 31 is an 11.92 -acre parcel that was also part of the B Pit mining area. This <br />area was graded to blend into the undisturbed area to the west and the reclaimed mining and <br />operational areas to the east resulting in a gentle, east -facing slope. Final revegetation seeding <br />with the DRMS-approved permanent seed mixture took place in the fall of 2009. This <br />Reclamation Area has previously received Phase I bond release but has not received Phase II <br />release. <br />Total vegetation cover on Reclamation Area 31 averaged 38.9% (Table 20, Appendix A) which <br />was a substantial decrease from the 64.8% cover observed in 2016. However, non -noxious <br />vegetation cover was 37.1% which was an increase from the 27.4% observed in 2016. Non - <br />noxious vegetation cover in Reclamation Area 31 met sample adequacy with the minimum 15 <br />samples. No excess annual cover was recorded; thus, the non -noxious cover was used for <br />hypothesis testing. <br />Table 20: Reclamation Area 31 Summary StaNctirc <br />Area 31 <br />90% <br />Summary Statistics <br />Reclamation Success <br />Reclamation <br />Technical <br />Criteria <br />Area <br />Standard <br />Pass? <br />Allowable* Cover % <br />30.6 <br />33.6 <br />No <br />Allowable* Production <br />2.0 <br />Allowable Vegetation Cover <br />37.1 <br />m2 <br />116.0 1 <br />136.1 <br />Yes <br />Species Composition <br />0.1 <br />0.1 <br />Woody Cover <br />(perennial grass, warm, cool <br />3,07 <br />3,1 <br />No <br />6.2.3 Reclamation Area 31 <br />Reclamation Area 31 is an 11.92 -acre parcel that was also part of the B Pit mining area.
