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 included <br />13 grass taxa, 23 forbs, 1 sub - shrub, and 10 shrubs and trees (Table 1). Found in relatively small quantities <br />were the state - listed noxious weeds, cheatgrass (Anisantha tectorum), Russian knapweed (Acrooti /on <br />re,oens), musk thistle (Carduus nutans), Canada thistle (Cirsium arvense), and field bindweed (Convovu /us <br />arvensis). In addition, the ubiquitous, invasive species Japanese brome (Bromus japonicus) was also <br />present in small quantities. With regard to the Phase II Bond Release success standard, the West Mine's <br />perennial average cover of 51.68% with an additional 5.94% contributed from annual and biennial cover <br />(equates to the maximum of 10% relative cover allowable) totals 57.62% (Chart 1). This value modestly <br />exceeds the success criterion of 54% (90% of the Total Plant Cover Standard). With regard to the Phase <br />II Bond Release success standard, the Run of Mine's perennial average cover of 49.50% with an additional <br />3.93% contributed from annual and biennial cover totals 53.43 %. This value substantially exceeds the <br />success criterion of >40 %. Both of these units therefore pass the Phase II Bond Release success <br />comparison. <br />Chart 1 <br />Bowie #1 Mine - Phase II Bond Release <br />Total Plant Cover Standard Comparison - 2013 <br />70 <br />60 <br />57.62 <br />c 50 <br />54 <br />53.43 <br />V <br />a <br />m <br />a <br />West Mine <br />40 <br />Success <br />--- - - - - -- <br />+°• <br />o <br />Perennial Cover <br />Criterion - <br />40 <br />51.68 <br />90% of Total <br />30 <br />Plant Cover <br />Perennial Cover - <br />Annual & Biennial <br />Standard <br />49.50 <br />IL <br />Contribution - <br />(60 %) <br />5.94 <br />Annual & Biennial <br />Run of Mine <br />20 <br />Contribution - <br />Success <br />3.93 <br />Criterion - <br />( >40 %) <br />10 <br />0 <br />West Mine Success Criterion Run of Mine Success Criterion <br />CEDAR CREEK ASSOCIATES, INC.
