• Total annual herbaceous production of BRB-3 2 90% of weighted total annual herbaceous <br />production from the reference areas (weighted based on 83% original extent of Mountain Brush / <br />Aspen and 17% original extent of Sagebrush). <br />The Mountain Brush/Aspen and Sagebrush Reference Areas will be sampled to adequacy first to <br />establish the standards for comparison against subsequently collected reGaimed area values. If <br />after 15 cover or 30 production samples have been completed in BRB-3, sample adequacy has <br />been achieved and the reclamation area mean total herbaceous foliar cover and herbaceous <br />production are above 90% of the reference area<lerived standard, an affirmative indication of <br />reclamation cover success will be asserted. <br />If: The mean herbaceous cover or production of an adequate sample from BRB-3 was less than <br />90°h of the cover standard (see above), then aone-sample t-test was made in the following form <br />to test the hypothesis of reclamation success for cover (CDMG 2003 proposed rules revisions, <br />4.15.11 (2)(b)): <br />f Q-X <br />c = <br />SF <br />Where: <br />x =Bond Release Block Sample Mean <br />Q = 80% of Standard <br />Ss =Standard error of mean [s/~] <br />S =Sample standard deviation <br />n =Sample size <br />t< = Calculated t value <br />$ = Table t value <br />The null hypothesis being tested is that the bond release block mean (µ) is greater than or equal <br />to 90% of the standard, stated as H,: µ >_ Q. If fc is less than or equal to the 1-tailed t table value <br />for alpha error probability of 0.10, at (n-1) degrees of freedom (infinite degrees of freedom may be <br />used if n>30), then Ho is not rejected, and revegetation is deemed successful for the parameter <br />tested. <br />C_ <br />
