The locations of these <br />reference areas are shown on the Vegetation map (Map 4) and Regional Vegetation map (Map 3). <br />An additional reference area was established in 2018, the Collom Aspen reference area, and the <br />location of it is shown on Map 4C Sheet 1. Extensive, detailed vegetative sampling was performed, <br />duplicating the methodologies as described in Section 2.04.10. <br />The reference areas were sampled for herbaceous cover, herbaceous production and woody plant <br />density. Species diversity was determined utilizing herbaceous cover data from the premining <br />inventory of the sagebrush, mountain shrub, and aspen communities. The reference areas are each <br />approximately seven acres in size. <br />Statistical tests were performed on the vegetative data from the reference areas to prove that they <br />were comparable to the premined area. The parameters compared were herbaceous cover and <br />herbaceous production. <br />Sample size adequacy tests were performed on both the premine and reference area data to insure <br />that representative cover and production data had been obtained at the 80% level of confidence. <br />Rule 4 Performance Standards 4-60 Revision Date: 11/27/18 <br />Revision No.: TR -129 <br />
