directional bearing was randomly selected and the GPS unit was used to indicate the <br />bearing. When a transect intercepted the inventory boundary, the directional bearing <br />was reversed 180 degrees to continue along the 50-meter length. A 10-point frame set <br />at 5-meter intervals along each transect was used to collect individual observations. <br />Sample adequacy calculations were performed after 15 transects were completed on <br />each site of each year. Since the mean of allowable vegetation, (total vegetation <br />cover) - (noxious weeds + excess annuals and biennials), in all cases was greater than <br />90% of the standard, only the sample size formula without hypothesis testing has been <br />provided in this document. It should be noted that the total vegetation cover sample <br />mean and total vegetation cover sample variance were used in the sample adequacy <br />calculations. This approach was mutually agreed to by CDMG in an effort to simplify <br />the statistical analyses and [he I S transects measured greatly exceeded the calculated <br />minimum number of transects required in all cases. Sample adequacy information for <br />each area is provided as follows: East Ridge -Appendix B, Center Ridge -Appendix <br />C, and South-of-Shop -Appendix E. <br />East Ridge -East Ridge was initially mined prior to any reclamation laws. However, <br />a portion was re-mined and reclaimed under the federal Surface Mining Control and <br />Reclamation Act (SMCRA; P.L. 95-87) Interim Regulations and the Colorado Mined <br />Land Reclamation Act (CMLRA) Regulations (effective May, 1977). This portion of <br />the area did not undergo final seeding until after the promulgation of the Colorado <br />Surface Mining Reclamation Act (CSMRA) Regulations (effective August 30, 1980). <br />Therefore, this portion of East Ridge was included in the estimation of the <br />reclamation liability bond associated with Permit C-80-001. <br />
