. 4rev), which had minimized herbaceous seeding to enhance shrub establishment, also <br />met 90% of the standard (31.8% allowable cover). The figure for allowable cover in <br />BRB4rev (28.8%) is the result of subtracting shrub cover (0.8%) and perennial noxious <br />weed cover (0.75%) and "excess annual/biennial cover" (3.6% which includes the non- <br />allowable cover by houndstongue) from the observed first-hit total vegetation cover of <br />33.9%. <br />A t-test of the assertion that the BRB-4rev allowable cover is indistinguishable from 90% <br />of the standard is as follows: <br />tc=(31.8-28.7)/(11.9/Sgrt24)=1.28 <br />Since critical t = 1.319 (one-tailed, alpha = 0.1, 23 df) and t< is less than this critical <br />value. reclamation success for Phase II is demonstrated. <br /> <br />• <br />28 <br />
