• also employ a simple random design rather than anacreage-weighted or proportional- <br />allocation model. <br />Seventeen samples were placed within the reference area, exceeding the sample <br />adequacy value of 12.1 (Table B9). Ttansect absolute cover values ranged from 36% <br />to 66`Y . Fifty production plots and seventeen woody stem yuadrats were also sampled. <br />A photo taken at ground level inside the reference area is included in the back of <br />Appendix B. <br />Absolute cover (JWref): (Tables A2, B1) Total vegetative cover exceeded <br />the baseline area by 5.4% absolute cover. Much of this difference was attributable to <br />an increase in cheatgrass (7.2% abs. cover in reference area vs. 2.1% in the baseline <br />area). The perennial, non-noxious cover value of 39.2% was higher than the baseline <br />• area value, but by less than a percentage. As Table B10 shows, the calculated t-value <br />of 0.194 is lower than the corresponding table t value of 1.684. Therefore, the null <br />hypothesis is accepted, meaning that the reference area and baseline perennial, non- <br />noxious cover are statistically equivalent. <br />Relative cover (]Wref): (Tables A7, 134) Fifteen of the twenty-two perennial <br />species present in the multiple hit data were also sampled in the JW baseline area. The <br />three dominant perennial species, snowberry, juniper, and Gambel oak, were also <br />shared. The reference area was different in some respects though, probably due more <br />to the confined nature of its acreage than any other factor. Cheatgrass was more <br />prevalent in the reference area (second highest relative cover - 12.8%) as were Mule's <br />ear (Balsamorhiza sagitata) and waterleaf (Hydrophyllum capitatum).
