Page 2 <br />June 11, 2018 <br />therefore reference area data is not used for this standard. The standard is 500 woody stems/ac as <br />outlined in the permit Section 3.0 Reclamation Plan, page 3-21. <br />The woody plant density was 1,733 and 2,825 stems/ac in 2016 and 2017, respectively. The <br />woody plant density standard was demonstrated to be successful for both 2016 and 2017. <br />Diversity Standard <br />The diversity standard has 3 criteria as outlined in permit Section 3.0 Reclamation Plan, page 3- <br />21. The standards are as follows: a) a minimum of three (3) perennial species contribute a <br />minimun of 3% relative cover, b) at least two (2) of those species must be cool -season grasses <br />and c) no individual species shall represent more than 60% relative cover. <br />In 2016, five perennial species contributed at least 3% relative cover: great basin wildrye (3.1%) <br />western wheatgrass (6.54%), northern sweetvetch (11.26%), rubber rabbitbrush (4.68%) and <br />basin big sagebrush (24.52%). Two of these species, great basin wildrye and western wheatgrass <br />are cool -season grasses. Basin big sagebrush was the largest contributer of relative cover at <br />24.52% which is below the maximum allowable relative cover of 60%. <br />In 2017, five perennial species contributed at least 3% relative cover: great basin wildrye <br />(8.19%) western wheatgrass (16.23%), northern sweetvetch (7.74%), rubber rabbitbrush (7.00%) <br />and basin big sagebrush (27.94%). Two of these species, great basin wildrye and western <br />wheatgrass are cool -season grasses. Basin big sagebrush was the largest contributer of relative <br />cover at 27.94% which is below the maximum allowable relative cover of 60%. <br />The diversity standards were demonstrated to be successful for both 2016 and 2017. <br />
