The locations of these reference areas are <br />shown on the Vegetation map (Map 4) and Regional Vegetation map (Map 3). Extensive, detailed <br />vegetative sampling was performed, duplicating the methodologies as described in Section 2.04.10. <br />The reference areas were sampled for herbaceous cover, herbaceous production and woody plant density. <br />Species diversity was determined utilizing herbaceous cover data from the premining inventory of the <br />sagebrush and mountain shrub communities. The reference areas are each approximately seven acres in <br />size. <br />Statistical tests were performed on the vegetative data from the reference areas to prove that they were <br />comparable to the premined area. The parameters compared were herbaceous cover and herbaceous <br />production. <br />Sample size adequacy tests were performed on both the premine and reference area data to insure that <br />representative cover and production data had been obtained at the 80% level of confidence. <br />Rule 4 Performance Standards 4-55 Revision Date: 8/28/17 <br />Revision No.: TR -115 <br />
