3.0 RESULTS <br />3.1 Summary <br />The revegetation evaluated for Phase II Bond Release comprised approximately 24 acres. A total <br />of 46 plant taxa were observed within both revegetation areas evaluated in 2013. These species <br />included 13 grass taxa, 23 forbs, 1 sub - shrub, and 10 shrubs and trees (Table 1). Found in relatively <br />small quantities were the noxious weeds, Russian knapweed (Acropti /on repens), musk thistle (Carduus <br />nutans), Canada thistle (Cirsium arvense), and field bindweed (Convovu /us arvensis). In addition, the <br />ubiquitous, invasive species cheatgrass (Anisantha tectorum), and Japanese brome (Bromus japonicas) <br />were also present in small quantities. With regard to the Phase II Bond Release success standard, the <br />West Mine's perennial average cover of 53.93% with an additional 6.09% contributed from annual and <br />biennial cover (equates to the maximum of 10% relative cover allowable) totals 60.02% (Chart 1). This <br />value modestly exceeds the success criterion of 54% (90% of the Total Plant Cover Standard). With <br />regard to the Phase II Bond Release success standard, the Run of Mine's perennial average cover of <br />49.50% with an additional 4.77% contributed from annual and biennial cover totals 54.27 %. This value <br />substantially exceeds the success criterion of 36% (90% of the Total Plant Cover Standard). Both of <br />these units therefore pass the Phase II Bond Release success comparison. <br />Chart 1 <br />Bowie #1 Mine - Phase II Bond Release <br />Total Plant Cover Standard Comparison - 2013 <br />70 <br />60 <br />60.02 <br />54.27 <br />> <br />s0 <br />U <br />(60 %) R <br />Run of Mine <br />C <br />6.09 A <br />Annual &Biennial S <br />Success <br />Cover - 4.77 C <br />West Mine <br />IL 40 <br />Success <br />Plant Cover <br />Perennial Cover - <br />Criterion- <br />° ° ° ° ° ° °° <br />° °�° <br />F <br />53.93 <br />90% of Total <br />c <br />30 <br />Plant Cover <br />Perennial Cover - <br />Annual &Biennial <br />Standard <br />49.50 <br />a <br />Contribution <br />20 <br />10 <br />0 <br />West Mine Success Criterion Run of Mine Success Criterion <br />CEDAR CREEK ASSOCIATES, INC.
