Table 7: Reclamation Area 32 Success Criteria
6.1.3 Reclamation Area 33
Reclamation Area 33 is a 12.5 -acre parcel that was formerly part of the Long -Term Spoil Area.
This area was graded to blend into the reclaimed mining and operational areas to the west
resulting in an almost flat, east -facing slope. Final revegetation seeding with the DRMS-
approved permanent seed mixture took place in November 2015.
Total vegetation cover on Reclamation Area 33 averaged 43.1 % (Table 8, Appendix A), and
total non -noxious vegetation cover was 42.3%. Non -noxious vegetation cover in this area met
sample adequacy with the minimum 15 samples. Two species contributed to the cover in all 15
transects, prairie sandreed and blue grama, contributing a combined 69.4% of the overall relative
cover. Cheatgrass only contributed 1.7% of the total relative cover in this Reclamation Area.
Fifteen species from four life forms contributed to the cover data and 10 other species were
encountered along the transects (Table 9, Appendix C). Twenty grasses and five forbs were
recorded, 23 of which were native or desirable and two were introduced. There were 17
perennial species and eight annual species. Both warm and cool season grass species contributed
to the cover including seven warm season perennial species, five cool season perennial species,
and two cool season annual species.
