STATISTICAL ANALYSIS <br />No statistical analysis was required for comparison as reclaimed area sample means for <br />vegetation cover and total herbaceous production exceeded the corresponding sample <br />mean success criteria from the reference area in both 2015 and 2016. <br />SPECIES IDENTIFICATION AND VERIFICATION <br />Species identification was accomplished in the field through the use of plant <br />identification keys (Harrington, 1954, Weber, 1987; Whitson, 1987; Zimdahl, 1990, <br />Stubbendieck, et al, 1995). In cases where plant identification was inconclusive in the <br />field, voucher specimens were pressed for lab identification. <br />FINAL REVEGETATION SUCCESS STANDARDS <br />Section 2.05.4(2)(e) Revegetation of the approved permit document contains the final <br />revegetation success criteria for the Carbon Junction Mine. These revegetation success <br />criteria are presented below (for the primary post -mining land use of dryland pasture). <br />"The following will be the revegetation success criteria for the Carbon Junction Mine <br />where the post -mining land use is dryland pasture: <br />Vegetation Cover <br />Vegetation cover of the reclaimed area will be successful when total live vegetation cover <br />is equal to or greater than 90 percent of the total herbaceous vegetation cover of the <br />approved reference area with 90 percent statistical confidence. <br />Herbaceous Production <br />Herbaceous production (defined as current year above -ground biomass of herbaceous <br />vegetation) of the reclaimed area will be successful when total herbaceous production is <br />equal to or greater than 90 percent of the total herbaceous production of the approved <br />reference area percent with 90 percent statistical confidence. <br />Woody Plant Density <br />There shall be no woody plant density revegetation success standard pursuant to the <br />request of the surface landowner that woody plants not be actively re-established on the <br />reclaimed areas of the Carbon Junction Mine. <br />Species Composition <br />The species composition revegetation success standard was derived from quantitative <br />sampling of the approved reference area, and represents the significant species <br />contributing to the composition of the reference area, based on seasonality, lifeform, and <br />origin. <br />Carbon Junction Mine Phase III Bond Release Application June 2016 Page 6 <br />
