EXECUTIVE SUMMARY <br /> Cedar Creek Associates, Inc. was contracted in 2019 and 2021 by Bowie Resource, LLC to evaluate <br /> the revegetated West Mine areas at the Bowie No. 1 Mine for the first and second years of a two-year <br /> Phase III Bond Release effort. Field studies conducted in 2019 and 2021 to evaluate revegetation efforts <br /> have shown that the target reclaimed plant communities have met the target success criterion for Phase <br /> III Bond Release(Table 1). Ground cover of desirable plants within the reclaimed areas compares favorably <br /> to established technical standards and plant succession is occurring and progressing in a positive direction, <br /> indicating that plants are self-sustaining. <br /> Table 1 Bowie #1 Mine <br /> Revegetation Success Criteria Comparisons - 2019 & 2021 (per TR-63) <br /> Plant Cover Production Woody Plant Density <br /> Live Trees,Shrubs,and Sub-Shrubs <br /> Annual(Total) (per acre) <br /> Total Plant Cover* Herbaceous* <br /> (%average cover) Reverse Null <br /> Area Year (pounds per acre) Average Ranked "L"Test <br /> Sampled (If n >_ 75) (If n < 75) <br /> Success Criteria >54% >405 >90 >90 <br /> 2019�79.SPass 1,089 Pass 366 N/A1 91Z �N/ <br /> West Mine2021 549 Pass 341 Pass3 N/A <br /> Diversity (Number of Species) <br /> Total Native or Total Native Total Native or Total Native Sub- <br /> Introduced Perennial Introduced Shrubs,Trees,and <br /> Perennial Cool-Season Perennial Farbs Shrubs <br /> Herbaceous Grasses <br /> Area Year (Between 0.5&60% Relative Cover) (<80% Rel.
