SAMPLING ADEQL;ACY <br />c~ <br />Results of sampling adequacy evaluation at the SOB oonfidence level are <br />provided in Table 18. As shown by the table, all sample data are adequate <br />with confidence levels ranging frcun 86.4 - 99.6%. <br />New proposed Colorado Mined Land Reclamation Board regulations (1979) <br />do not require shrub productivity data. Since the Seneca II baseline <br />vegetation study was ~~leted prior to the new regulations, shrub <br />production data are included in all data sets for mixed brush type/ <br />aspen subtype and upland sagebrush sample units. Sample adequacy <br />inclusive of shrub data was calculated arxi the calculated ~nfide-.ce <br />levels are shown in Table 18. Table 19 shows sample adequacy of <br />production data in the absence of shrub production data. <br /> <br />~• <br />-65- <br />
