The following list presents the similarity <br />between the sample plots and reference areas. <br /> Relative Relative $ <br />Vegetation Total No. Diversity No. Major ~ of Major of Index per <br />Type Species Index ~ Species Species * Major Species <br /> <br />Sagebrush. 25 0.975 6 24 67 <br />Sagebrush- <br />grass iref) 28 <br />• <br />• - <br />.919 7 <br />25 <br />72 <br />779-72 ccccc <br />
