Keenesburg Mine 2018 Vegetation Monitoring Report <br />Table 16: Reclamation Area 29 Success Criteria <br />6.2.2 Reclamation Area 30 <br />Reclamation Area 30 is a 9.7 -acre parcel that was formerly 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 November 2006. 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 30 averaged 40.4% (Table 17, Appendix A) which <br />was a decrease from the 55.2% cover observed in 2016. However, non -noxious vegetation cover <br />was 38.4% which was an increase from the 30.6% observed in 2016. Non -noxious vegetation <br />cover in Reclamation Area 30 met sample adequacy with the minimum 15 samples. Four native <br />annual species (two grasses and two forbs) contributed a total of 29.3% of the overall relative <br />cover which exceeded the allowable 10% to be used in final hypothesis testing. Thus, the <br />average allowable vegetation cover was only 30.6%. <br />Table 17: Reclamation Area 30 Summary Statistirs <br />Area 30 <br />90% <br />Mean <br />Reclamation Success <br />Reclamation <br />Technical <br />Criteria <br />Area <br />Standard <br />Pass? <br />40.4 <br />1.9 <br />Non -Noxious Vegetation Cover <br />38.4 <br />Allowable* Cover % <br />30.9 <br />33.6 <br />Yes <br />Allowable* Production <br />36.3 <br />2.4 <br />Forb Cover <br />m2 <br />68.6 <br />136.1 <br />No <br />Species Composition <br />Non -Noxious Relative Cover Statistics <br />(perennial grass, warm, cool <br />4,0 <br />3,1 <br />No <br />6.2.2 Reclamation Area 30 <br />Reclamation Area 30 is a 9.7 -acre parcel that was formerly part of the B Pit mining area.
