• acres), Topsoil Pile C (1.8 acres), the Sanitary Landfill site (2.7 acres), and the Explosives <br />Storage site (4.7 acres) were included in the sampling program, but were put into separate <br />units so at least one sample was collected from each of these azeas. This was a modified <br />proportional allocation scheme with random sample site locations. The four reference <br />areas sampled include the Aspen, Sagebrush, Oak Brush, and Chokecherry vegetation <br />types. These four vegetation reference areas were sampled separately for herbaceous <br />cover and herbaceous production with weighted averages computed for the final bond <br />release comparisons. Sample sites aze shown on the 1996 study area and sample site <br />location map in Appendix F. <br />1996 Revised Analyses <br />The 1996 revised data analyses separated small non-contiguous areas into <br />individual sampling units. Therefore, data for Topsoil Pile B, Topsoil Pile C, the Sanitary <br />Landfill site and the Explosives Storage area were removed and evaluated sepazately. The <br />data for the remaining lazge contiguous reclaimed areas were analyzed as one area. No <br />change to the analyses of the reference azea data was requested. <br />1997 Studv <br />In 1997, the entire reclaimed azea, including small non-contiguous reclaimed sites, <br />was sampled as one unit using the simple random method for sample site location. If <br />random samples for a speciSc vegetation parameter being analyzed did not fall within <br />small non-contiguous reclaimed azeas then additional random samples were located at <br />those sites. These additional samples were kept separate from the other data and were <br />used primarily for description purposes. The reference azeas were sampled using the same <br />areas and methods as the 1996 sampling. Sample sites are shown on the 1997 study area <br />and sample site location map in Appendix F. <br />2 <br />
