The PSCM herbaceous production standard and success evaluation is also based on <br />the weight averaged value for current annual herbaceous production derived from sampling in <br />the approved PSCM sagebrush and mountain brush reference areas. The weighting contribution <br />is mountain brush 83% and sagebrush 17%. Based on the production sampling an allowable <br />herbaceous production value is determined by excluding noxious weeds in production sampling <br />and allowing no more than 10% relative production of annual/biennial weeds. These exclusions <br />and the weight averaging determines the allowable herbaceous production standard. <br />Table 3. 2012 and 2014 Data and Sample Adequacy Summary for Total and Allowable <br />Herbaceous Production (pounds/acre), Phase III BRB PSCM-2. <br />Note: s, N, Nn. and t based on allowable herbaceous production data <br />Total <br />Allowable <br />Vegetation Type <br />Herbaceous <br />Herbaceous <br />s <br />N <br />N,,,;,, <br />t <br />Production <br />Production <br />Phase III Bond <br />Release <br />847.6 <br />847.6 <br />647.7 <br />35 <br />100 <br />1.307 <br />BRB PSCM-2 2012 <br />Phase III Bond <br />Release <br />1696.9 <br />1687.1 <br />899.13 <br />32 <br />49 <br />1.309 <br />BRB PSCM-2 2014 <br />Note: s, N, Nn. and t based on allowable herbaceous production data <br />
