employed when determining post-reclamation success. <br />Diversity success criteria were arrived at by utilizing herbaceous cover data from the pre-mining <br />inventory. Four species were found to comprise 43.4 percent of the diversity: Poa pratensis <br />(Kentucky Bluegrass), Ag_ropyron smithii (Western Wheatgrass), Achillea lanulosa (Western <br />Yarrow), and Stipa viridula (Green Needle Grass), which represent three perennial, cool season <br />grasses and one perennial forb. The revegetation objective for diversity is to establish a similar <br />community on the reclaimed areas. As with the cover and woody plant density standard, the <br />diversity success standard is broken down into three distinct reclaimed areas: the pre-2009 <br />grassland area, the 2009-forward area and the sagebrush steppe area. <br />Diversity on the pre-2009 reclamation will contain: <br />n) At least two cool season innerennial grasses x6fli bettznePn 30/ and ';n% relative omupr <br />(composition), and <br />b) All forbs combined with between 1 % and 50% relative cover (composition). <br />Diversity on the 2009-forward grassland area reclamation will contain: <br />a) At least three native cool season perennial grasses with between 3% and 50% relative <br />cover (composition), and <br />b) At least one perennial forb or shrub with between 2% and 50% relative cover <br />(composition), and <br />c) A total of all forbs or all shrubs combined with between 4% and 50% relative cover <br />(composition), or <br />d) If five or more native cool season perennial grass taxa contribute between 3% and <br />50% composition, the requirement for perennial forbs and shrubs shall be limited to <br />1 % or more of the relative cover. <br />The 2009-forward sagebrush steppe area reclamation will contain: <br />At least four native perennial species, each more than 3% composition, a minimum of <br />two of which are grasses and a minimum of one of which is a forb, with the following <br />caveat: <br />If no single forb species exceeds 3% composition, the forb requirement can be <br />met if. <br />a) At least two native perennial forb species combined comprise at least <br />2% composition, or; <br />Proposed Decision and Findings of Compliance 14 September 2009 <br />Permit Renewal 05 Page 63
