data sets for cover for the three reclamation areas as well as the five sampled extended <br />reference areas all achieved sample adequacy. Production data sets were nearly adequate <br />(Table 25). Note that no formal testing for phase three bond release that would involve <br />herbaceous production were undertaken this year, so achievement of adequacy was not at issue. <br />As would be expected, minimum sample sizes for background area shrub sampling far exceeded <br />those taken. <br />Phase /l Bond Release Hypothesis Testing <br />Average allowable cover observed in the Phase II bond release areas sampled in 2006 was <br />24.9%. <br />Assessment of fhe Phase /l Reclamation Area for Compliance with Performance Standards <br />The upper limit of the 90% confidence interval associated with the area sampled to produce cover <br />data applicable to a potential Phase II bond release application, which had minimized herbaceous <br />seeding to enhance shrub establishment, also met 90% of the standard (26.9% allowable cover). <br />The figure for allowable cover in this Phase II Area (24.9%) is the result of subtracting shrub <br />cover (0.2°l0) and perennial noxious weed cover (D.7%) and "excess annual/biennial cover" (6.3°l0 <br />which includes the non-allowable cover by the noxious species houndstongue, bull thistle, and <br />musk thistle) from the observed first-hit total vegetation cover of 32.1 %. <br />A t-test of the assertion that the 2006 Seneca IIW -Phase II area allowable cover is <br />indistinguishable from 90% of the standard is as follows: <br />fc = (26.9 - 24.9) / (8.7 / sgrt 20) = 1.03 <br />Since critical t = 1.319 (one-tailed, alpha = 0.1, 23 df) and t° is less than this critical value, <br />reclamation success for Phase II is demonstrated. <br />I~ <br />19 <br />
