success achieved and conducted a square root transformation calculation to demonstrate normalcy. The 2015 <br /> background woody plant density(WPD),data passed the square-root transformation test. The reverse null <br /> test demonstrated that background WPD was achieved for the 2015 background area. <br /> The 2016 woody plant density success evaluation is found on page 18 of the application. All areas; <br /> background,and fenced concentration plots exceeded the required standard for both required 1 and 2 woody <br /> plant density standards. Sample adequacy not achieved. In 2016 the operator collected 75 belt transects on <br /> the background(not concentrated plots),area allowing for a direct comparison to the standard. This is <br /> acceptable practice. <br /> Fenced plots in 2016;Aspen,and Riparian plots,did not achieve statistical sample adequacy. The operator <br /> demonstrated using the reverse null formula a square root transformation that the data met normalcy. The <br /> concentrated woody stem area plots exceeded the required woody plant standard for the 2016 data. <br /> The 2016 upland shrub plot met statistical sample adequacy and exceeded the woody plant standard for 2016. <br /> Woody plant success standards were achieved for the 2015 and 2016 sample data for background and the <br /> three concentrated shrub communities. <br /> Species Diversity <br /> Seneca II West has several different criteria for determining reclamation success for species diversity. <br /> Mandatory standard A requires that no one species comprise greater than 60%relative cover. <br /> For 2015,data Table J-1 demonstrates that the most abundant single species was Western wheatgrass <br /> (Pascopyrum smithii),with 23.7%relative cover. This is acceptable for 2015. <br /> Alternate Diversity Standard B: 75%species distribution in the combined weighted reference area, equates <br /> to 26.8 species per100 sq Meters(sq M). Probability adjusted the value to 20.2 species. 2015 BRB3 <br /> Adjusted to remove noxious species equates to 24.8 species/100 sq M.The BRB3 met Alternate Test B for <br /> 2015. <br /> Alternate Diversity Test C: The similarity index. Refer to table J7 for the 2015 data. The Similarity index <br /> between the lifeform species density for prescribed lifeforms for the 2015 BRB3 and the Mean Species <br /> Density for the acreage weighted reference area is 73%. This value exceeds 90%of the standard of 70%(0.9 <br /> X 70%=63%). Therefore,Alternate Diversity Test C was successful for BRB-3 for 2015. <br /> Alternate Diversity Test D: The total number of native species in an adequate sample of 2015 BRB3 <br /> herbaceous cover was 39. The total number of native species in an adequate sample of 2015 weighted <br /> reference area herbaceous cover was 23.6. The BRB3 native species exceeded that of the 2015 weighted <br /> reference area. Alternate Diversity Test D is considered successful for 2015. <br /> For 2015,BRB3,Mandatory Test A passed,alternate species diversity tests,B, C and D passed as well. The <br /> BRB3 is considered successful for species diversity for 2015. <br /> For 2016,the mandatory standard A requires that no one species comprise greater than 60%relative cover. <br /> For the 2016 data,Table J5 demonstrates that the most abundant single species was Alfalfa(Medicago <br /> sativa)with 28.6%relative cover. This is acceptable for 2016. <br /> Permit Number C1982057 Prepared by: R.Reilley NIS,GISP <br /> SL6 Phase II and III Page 13 of 16 <br />
