The Operator <br />will utilize the established reference area for the purpose of comparing <br />vegetation information between the reclaimed areas and the undisturbed <br />reference area for the variables of ground cover and production. For the <br />variables of woody plant density and species diversity, the Operator shall <br />compare revegetated area parameters against defined standards detailed <br />later in this section. Data to be used in these comparisons must be from <br />statistically adequate sampling (where necessary) as indicated in Rule <br />4.15.11. <br />Vegetation Cover <br />Vegetation cover of the revegetated area will be considered adequate for final <br />bond release if the perennial vegetation cover is not less than 90% of the <br />perennial vegetation cover as determined from the reference area with a 90% <br />statistical confidence utilizing one of the three methods detailed under Rule <br />4.15.11 (2) [(a), (b) or (c)]. <br />Herbaceous Production <br />Herbaceous production of the revegetated area will be considered adequate <br />for final bond release if the perennial herbaceous production is not less than <br />90% of the perennial herbaceous production as determined from the reference <br />area with a 90% statistical confidence utilizing one of the three methods <br />detailed under Rule 4.15.11 (2) [(a) (b) or (c)]. <br />Permit Application 2.05-37 04/11 <br />
