forbs per 100 sq.m. Data for total native species density in the 2003 reclamation areas was 30.5 <br />• species per 100 sq.m. in 2007, up more than fifteen species per 100 sq.m. since year 2005 (14.7 <br />species per 100 sq.m.; ESCO 2006). Average total species density on the reclaimed areas <br />exceeds that of the Sagebrush extended reference area (Figure 4). <br />Sample Adequacy <br />A summary of sample adequacy calculations for the parameters of cover, herbaceous production, <br />and woody plant density is presented in Table 16 (Appendix 1). As can be seen in this table, the <br />data sets for cover for the two reclamation areas as well as the two sampled extended reference <br />areas all achieved or were very close to achieving sample adequacy. Production data collected <br />did not reach sample adequacy (Table 16). Note that no formal testing for bond release that <br />would necessitate achievement of sample adequacy was undertaken this year, so achievement of <br />adequacy was not at issue. As would be expected, minimum sample sizes for background area <br />shrub sampling far exceeded those taken. <br />C~ <br />• <br />14 <br />
