3.9 Evaluation Techniques for Revegetation <br />Success of revegetation will be determined by comparison of reclaimed areas to <br />the big sagebrush shrubland reference area using the same techniques used in the <br />baseline vegetation inventory (WRDC 1980b). Parameters compared will include <br />vegetation canopy cover, annual production, and woody plant density. For <br />demonstrations of revegetation success, the parameters of vegetation cover, <br />herbaceous production and woody plant density would be sampled to statistical <br />adequacy and compared to the sagebrush reference area (cover and production) and <br />standards (woody plant density). Diversity comparisons will be made based on relative <br />cover values obtained from the statistically adequate sampling. Statistical adequacy will <br />be demonstrated using formulas recommended in the DMG's current bond release <br />guidelines. Statistical-tests of success will also follow the procedures recommended in <br />the bond release guideline. <br />The following success standards will be used to evaluate revegetation. <br />• Densi Big Sagebrush Shrubland 500 stems per acre <br />Diversi A minimum of three perennial species shall each provide a minimum of 3 <br />relative cover. At least two of these species must be cool season perennial grasses. No <br />individual species shall represent more than 60 % relative cover. <br />• Permit Renewal <br />3-21 <br />09/03 <br />
