Sample adequacy was calculated during 2012 and 2014 data collection based on allowable all -hit <br />herbaceous cover which is relevant to the cover success criteria. The sampling results and <br />statistics for allowable all -hit herbaceous cover are presented in Table 2 below. In 2012 and <br />2014, sample adequacy based on allowable all -hit herbaceous cover was achieved in BRB-1 and <br />each of the reference area types except for Mountain Brush (note that sample adequacy was met <br />when Mountain Brush all -hit total vegetation cover was assessed). The 2012 and 2014 Mountain <br />Brush sample adequacy approach and basis for application to success criteria evaluations is <br />addressed below following Table 2. Please refer to report text and Tables C4, G3 and G8 in the <br />vegetation bond release study report contained in Attachment D for more detail. <br />Table 2. 2012 and 2014 Data and Sample Adequacy Summary for Allowable All -Hit <br />Herbaceous Cover for the Yoast BRB-1 Phase III Bond Release and Reference Areas (RA). <br />Area <br />Allowable All -Hit <br />Herbaceous Cover (x) <br />s <br />N <br />N,,,;,, <br />t <br />BR13-1 Phase III Bond <br />Release Area 2012 <br />47.8 <br />11.84 <br />35 <br />11 <br />1.307 <br />A RA 2012 <br />53.67 <br />16.65 <br />21 <br />17 <br />1.325 <br />MB RA 2012 <br />28.85 (32.14) <br />11.36 <br />21 <br />27 <br />1.325 <br />SB RA 2012 <br />30.75 <br />8.79 <br />16 <br />15 <br />1.341 <br />SMB RA 2012 <br />14.44 <br />4.08 <br />16 <br />14 <br />1.341 <br />BRB-1 Phase III Bond <br />Release Area 2014 <br />60.63 <br />12.98 <br />32 <br />8 <br />1.309 <br />A RA 2014 <br />89.32 <br />21.51 <br />21 <br />10 <br />1.325 <br />MB RA 2014 <br />40.68 (47.86) <br />21.42 <br />16 <br />50 <br />1.341 <br />SB RA 2014 <br />35.40 <br />11.49 <br />20 <br />19 <br />1.328 <br />SMB RA 2014 <br />18.06 <br />3.94 <br />17 <br />9 <br />1.337 <br />1 Reference Area Types (RA): A = aspen, MB = mountain brush, SB = sagebrush, SMB = steep <br />mountain brush, WW/AS = western wheatgrass/alkali sagebrush <br />2 See text below for statistical measure to address sample adequacy and use of adjusted Mountain <br />Brush data for 2012/2014 success evaluations.
