in the reference area, annual grass component in the reclaimed area shall not exceed the relative cover <br />of the annual grass relative cover in the reference area by more than 5%. <br />For 2011 Greasewood Bond Release Block sampling results: <br />Perennial cool season grass relative cover was 1.2%. <br />Perennial warm season grass relative cover was 1.4%. <br />Forb & 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 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 />Forb & 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 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 average <br />perennial vegetative cover was 22.2%. 21.1% live vegetative cover was attributed to Cheatgrass <br />(Bromus tectorum [syn. Anisantha tectorum]). <br />Live vegetative cover measured in 2011 on the shadscale reference area was 50.10% with 8.5% 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 approved <br />reference area at a 90% confidence interval (PAP pg. 12-22). Cheatgrass contributed 39.7% relative <br />cover in the shadscale reference area in 2011. The relative cover contributed by Cheatgrass in the <br />reference area was considerably higher than the relative cover of Cheatgrass measured in the <br />Shadscale bond release block. 90% of the perennial live cover equals 7.65%. The Division finds the <br />shadscale reclaimed areas successful for vegetative cover for 2011. <br />Live vegetative cover measured in 2012 on the shadscale bond release block was 28.2%. The average <br />perennial vegetative cover was 21.15%. Cheatgrass contributed 6.0% live vegetative cover. <br />Live vegetative cover measured in 2012 on the shadscale reference area was 6.40% live vegetative <br />cover comprised of non -noxious perennial species. The reclamation success standard requires the <br />reclaimed area to meet or exceed 90% of the perennial vegetative cover on the approved reference <br />area at a 90% confidence interval (PAP pg. 12-22). Cheatgrass contributed 25.3% relative cover in <br />the shadscale reference area in 2012. 90% of the perennial live cover equals 5.76%. The Division <br />finds the shadscale bond release block successful for vegetative cover for 2012. <br />Page 18 <br />
