Since critical t = 0.853 (one -tailed, alpha = 0.2, 32-1 df) is exceeded by t,a,, (8.687), the hypothesis of no <br />difference is rejected and reclamation success for 2015 BRB-3 production under Phase III is <br />demonstrated. <br />WOODY PLANT DENSITY <br />Figure C-3 and C-4 graphically presents the "Background" and Fenced "Concentration" Area woody plant <br />density averages for the 2015 BRB-3, respectively. As can be seen, the 1939.5 stems per acre observed <br />in the "Background" area exceeds 180 stems per acre (90 percent of the 200 stems per acre standard). <br />The average woody plant density data in the "Background" area also exceeds 900 stems per acre (90 <br />percent of the 1000 stems per acre performance standard), thus the standard for "Volunteer" areas has <br />been demonstrated on 100% of the unfenced BRB-3. The 2696.4 stems per acre (of which 264.3 stems <br />were Aspen (Populus tremuloides) observed in the Fenced Aspen "Concentration" Area far exceeds 851 <br />stems per acre (90 percent of the 945 stems per acre performance standard; of which 150 stems must be <br />Aspen). The 2884.6 stems per acre (of which 899.2 stems were from tall shrub and tree species) <br />observed in the Fenced Riparian "Concentration" Area far exceeds 851 stems per acre (90 percent of the <br />945 stems per acre performance standard; of which 150 stems must be tall shrubs and/or trees). The <br />2227.4 stems per acre observed in the Fenced Upland "Concentration" Area far exceeds 851 stems per <br />acre (90 percent of the 945 stems per acre performance standard). Hence mean woody plant density in <br />all areas exceed 90% of the respective performance standards in 2015. <br />"Background" Density <br />Sample adequacy based on woody plant density was not achieved in the "Background" areas of the <br />Phase III BRB-3. Since the mean 'Background" woody plant density exceeded 90% of the mandatory <br />performance standard 1 and and mandatory performance standard 2 (Figure D-3, Table C-1), <br />reclamation success for Phase III woody plant density is demonstrated by passing a one sample t-test of <br />the "reverse null' hypothesis (CDMG 2005 revised rule, 4.15.11 (2)(c)). The 2015 BRB-3 "Background" <br />woody plant density data were first evaluated for normality using the Shapiro-Francia test. Based on the <br />2015 BRB-3 density data the normality test was not passed. Consequently a square root transformation <br />was performed and the normality test was passed (Table 3, below). Hypothesis testing calculations went <br />forward using square root transformed data for both the BRB-3 "Background" density data and the <br />technical standard. <br />9 <br />
