Perennial warm season grass relative cover was 1.4 %. <br />Form & Sub -shrub relative cover was 7.0 %. <br />No one species exceeded 70% relative cover. <br />The Division finds that the greasewood bond release block is successful for species diversity for <br />2011. <br />For 2012 greasewood bond release Block sampling results: <br />Perennial cool season grass relative cover was 1.2 %. <br />Perennial warm season grass relative cover was 1.2 %. <br />Form & Sub -shrub relative cover was 14.3 %. <br />No one species exceeded 70% relative cover. <br />The Division finds that the greasewood bond release block is successful for species diversity for <br />2012. <br />Shadscale Bond Release Block <br />Cover: Shadscale Bond Release Block 2011 & 2012. <br />In 2011 live vegetative cover measured on the shadscale bond release block was 47.8 %. The <br />average perennial vegetative cover was 22.2 %. 2 1. 1 % live vegetative cover was attributed to <br />Cheatgrass (Bromus tectorum [syn. Anisantha tectorum]). <br />Live vegetative cover measured in 2011 on the shadscale reference area was 22.19% with 8.5% <br />live vegetative cover comprised of non - noxious perennial species. The reclamation success <br />standard requires the reclaimed area to meet or exceed 90% of the perennial vegetative cover on <br />the approved reference area at a 90% confidence interval (PAP pg. 12 -22). Cheatgrass <br />contributed 39.7% relative cover in the shadscale reference area in 2011. The relative cover <br />contributed by Cheatgrass in the reference area was considerably higher than the relative cover <br />of Cheatgrass measured in the Shadscale bond release block. 90% of the perennial live cover <br />equals 7.65 %. The Division finds the shadscale reclaimed areas successful for vegetative cover <br />for 2011. <br />Live vegetative cover measured in 2012 on the shadscale bond release block was 28.2 %. The <br />average perennial vegetative cover was 21.15 %. Cheatgrass contributed 6.0% live vegetative <br />cover. <br />Live vegetative cover measured in 2012 on the shadscale reference area was 6.40% live <br />vegetative cover comprised of non - noxious perennial species. The reclamation success standard <br />requires the reclaimed area to meet or exceed 90% of the perennial vegetative cover on the <br />approved reference area at a 90% confidence interval (PAP pg. 12 -22). Cheatgrass contributed <br />4 <br />
