sampling to derive a weight averaged value (based on the four primary premine vegetation type <br />contributions to total acreage). The current 2012 and 2014 annual herbaceous production was <br />determined from sampling in the approved four vegetation types in the extended reference area. <br />The weighting contribution for each type is as described above under the Cover discussion. <br />Based on the production sampling an allowable herbaceous production value is determined by <br />excluding noxious weeds and allowing no more than 10% relative production of annual/biennial <br />weeds. The allowable herbaceous production values for the four vegetation types in the reference <br />area are used in the weight averaged calculations to determine the production standard. <br />Table 3. 2012 and 2014 Data and Sample Adequacy Summary for Total and Allowable <br />Herbaceous Production (pounds/acre) for the Yoast BRB-1 Phase III Bond Release Area. <br />Table 4.2012 and 2014 Data and Sample Adequacy Summary for Total and Allowable <br />Herbdceous Production (pounds/acre) in the Reference Area Vegetation Types for the <br />Yoast BRB-1 Phase III Bond Release Herbaceous Production Performance Standard. <br />Vegetation Type <br />Total <br />Allowable <br />s <br />N <br />N,,,;,, <br />t <br />Vegetation Type <br />Herbaceous <br />Herbaceous <br />s <br />N <br />N,,,;,, <br />t <br />MB RA 2012 <br />Production <br />Production <br />235.5 <br />31 <br />55 <br />1.309 <br />BRB-1 Phase III <br />444.3 <br />444.3 <br />306.9 <br />31 <br />82 <br />1.309 <br />Bond Release Area <br />1138.4 <br />1130.8 <br />1011.4 <br />35 <br />137 <br />1.307 <br />2012 <br />BRB-1 Phase III <br />Bond Release Area <br />2257.2 <br />2257.2 <br />1099.2 <br />32 <br />41 <br />1.309 <br />2014 <br />Table 4.2012 and 2014 Data and Sample Adequacy Summary for Total and Allowable <br />Herbdceous Production (pounds/acre) in the Reference Area Vegetation Types for the <br />Yoast BRB-1 Phase III Bond Release Herbaceous Production Performance Standard. <br />Vegetation Type <br />Total <br />Herbaceous <br />Production <br />Allowable <br />Herbaceous <br />Production <br />s <br />N <br />N,,,;,, <br />t <br />A RA 2012 <br />662.0 <br />662.0 <br />417.5 <br />31 <br />69 <br />1.311 <br />MB RA 2012 <br />417.5 <br />417.5 <br />235.5 <br />31 <br />55 <br />1.309 <br />SB RA 2012 <br />444.3 <br />444.3 <br />306.9 <br />31 <br />82 <br />1.309 <br />SL -6 - 13 <br />
