" Revised August 1996 <br />• Since the reference area is to remain undisturbed during the life of the <br />mining operation to insure that reclamation success criteria can be <br />measured after final reclamation, another suitable sagebrush reference <br />area was chosen. <br />For demonstration of revegetation success, vegetation cover, herbaceous <br />production, and woody plant density will be sampled to statistical <br />adequacy, and compared to the approved standard. The Division has <br />completed a comprehensive bond release guideline that provides a good <br />overview of recommended sampling approaches, statistical adequacy <br />formulas and statistical tests. Colowyo will follow the procedures <br />recommended in the guideline or utilize other procedures that are as <br />affective as the Division's recommendations. Before Colowyo begins a <br />vegetation sampling program for bond release, we will meet with the <br />Division to discuss and confirm sampling approaches and statistical <br />testing. <br />• <br /> <br />
