U <br />the mean dry weight of all species in all plots within each vegetation type <br />sampled. Production was expressed in grams per square meter and pounds per <br />acre for each type. <br />2.6.3 Density <br />Shrub density was computed as the mean number of plants per 50 square <br />meters and the mean number of plants per 0.1 acre for all species. <br />Tree density was computed as the mean number of plants per 100 square <br />meters and the mean number of plants per 0.1 acre for all. species. <br />2.6.4 Species Diversity <br />Species diversity was computed as the mean number of different species <br />encountered by vegetation hits along the 50 meter cover transect. <br />2.6.5 Statistical Equivalency of Reference Area <br />The statistical equivalency of each reference area with the study area <br />was determined for vegetation cover, production and species density in each <br />vegetation type according to the following equation (OSM 1980): <br />s12 sZZ <br />zl-zz<or>t + <br />nl nZ <br />z = sample mean <br />s2 = sample variance <br />t = t table value for 90% confidence level <br />n = sample size <br />2.6.6 Livestock Carrying Capacity <br />Livestock carrying capacity of each vegetation type was determined by <br />considering the nutritional requirements of cattle and sheep (Stoddart et <br />7 <br />L~ <br />Exhibit 10, Item 5 Revision Date: 03/06/07 <br />12 Revision No.: PR-02 <br />
