reference areas with adjustments made for woody plants, noxious weeds and no more than 10% <br />relative cover of annual/biennial weeds. The resulting allowable first hit herbaceous cover <br />standard is determined by weight averaging the values based on the percent contribution of the <br />mountain brush and sagebrush types. This reference area basis value is multplied by two (2) to arrive at <br />the cover success standard. The Phase III bond release area sample value md/1 be no less than 90% of the cover <br />success standard at 90% statistical confidence. In both the reference area derived standard and the <br />Phase III reclaimed area, the adjusted herbaceous cover is herein referred to as the allowable <br />herbaceous cover. The derivation of the first hit allowable herbaceous cover for the Phase III <br />bond release block and reference areas is included in the discussion and tables in the 2012/2014 <br />revegetation success evaluation report included in Attachment D — Revegetation Success <br />Supporting Documentation. <br />Table 1 provides a summary of the cover attributes for the BRB PSCM-2 Phase III bond release <br />block and the mountain brush and sagebrush native reference areas for years 2012 and 2014. <br />Table 1 also includes the allowable first hit herbaceous cover values for these communities. <br />Please refer to the report discussion and Tables A-1, A-5, A-7, B-1, B-5, B-7 and C-1 in <br />Attachment D — Revegetation Success Supporting Documentation. <br />Table 1. 2012 and 2014 Vegetation Cover Sampling Data Summary in the Phase III BRB <br />PSCM-2 Bond Release and Reference Areas (RA). <br />Total <br />Total First Hit <br />First Hit <br />Allowable <br />Standing <br />Litter <br />Rock <br />Bare Soil <br />Area <br />Cover <br />Herbaceous <br />Dead (%) <br />(%) <br />(%) <br />(%) <br />(%) <br />Cover (%) <br />Phase III Bond <br />Release BRB <br />35.3 <br />32.4 <br />3.7 <br />37.5 <br />5.5 <br />17.9 <br />PSCM-2 2012 <br />Mountain Brush <br />79.8 <br />8.7 <br />2.4 <br />15.4 <br />- <br />2.3 <br />RA 2012 <br />Sagebrush RA <br />47.2 <br />28.3 <br />3.3 <br />42.7 <br />0.1 <br />6.7 <br />2012 <br />Phase III Bond <br />49.4 <br />47.1 <br />0.7 <br />27.3 <br />5.8 <br />16.8 <br />
