Greater than 30 samples were taken in the bond release area to allow for hypothesis testing using <br /> the reverse null hypothesis. Sample adequacy based on all-hit values was calculated for the bond <br /> release area and achieved for each of the reference areas. <br /> BRB-2a Cover <br /> Calculation of the 90 percent of the cover standard for the 2016 sampling is demonstrated below. <br /> Cover standard derivation: <br /> Aspen Reference Area Allowable All-Hit Herbaceous Cover' = 74.6% <br /> Mountain Brush Reference Area Allowable All-Hit Herbaceous Cover' =44.9% <br /> Sagebrush Reference Area Allowable All-Hit Herbaceous Cover' = 36.4% <br /> Steep Mountain Brush Reference Area Allowable All-Hit Herbaceous Cover' = 28.2% <br /> Herbaceous cover adjusted by subtracting noxious weeds and annual/biennial plant cover in excess of <br /> 10%of the remainder <br /> 90% of the ERA area weighted Cover Standard= <br /> 0.90*[0.244(74.6%) +0.489(44.9%) +0.24(36.4%) +0.027(28.2%)] =44.7% <br /> The mean allowable all-hit herbaceous vegetation cover sampled in 2016 BRB-2a was 48.4%, <br /> exceeding 44.7%, which is 90% of the area-weighted cover performance standard (see also <br /> Figure B-la, Table B-1). This direct comparison of reclaimed area mean to standard is allowed <br /> under DRMS rules (CDMG 2005 revised rule, 4.15.11 (2)(a))when sample adequacy has been <br /> demonstrated for the reclaimed and reference areas. Thus for 2016, successful revegetation with <br /> respect to allowable all-hit herbaceous cover is demonstrated. <br /> BRB-3 Cover <br /> Calculation of 90 percent of the cover performance standard based on the Haul Road Reference <br /> Areas appropriate for 2016 sampling is demonstrated below. <br /> 90% of the Haul Road Cover Standard = 0.90*27.4% = 24.7% <br /> SL-8 - 7 <br />
