WOODY PLANT DENSITY <br /> The criterion for determining woody plant density success at the Yoast mine site is based on <br /> standards categorized as primary and secondary. The primary standards are as follows: (P 1) <br /> background average woody density will be> 200 stems per acre in upland areas and (P2) at least <br /> 10%of the bond release block will be> 1000 stems per acre of concentrated woody density outside <br /> of fenced upland sites. Success is evaluated using 90% of the standard or 180 stems per acre <br /> (background) and 900 stems per acre (concentrated), respectively. Additionally, there are three <br /> secondary standards of which at least two must be satisfied if applicable. Upland fenced shrub <br /> areas (S1) must have at least 945 stems per acre, riparian fenced and non-fenced areas (S2) must <br /> have 945 stems per acre with 150 of the stems being tall shrub or trees and aspen fenced areas(S3) <br /> must have 945 stems per acre with 150 of the stems as aspen. In the case of the Yoast BRB-2 <br /> release area, there is both a designated Fenced Aspen Woody "Concentration" area as well as a <br /> Fenced Upland Woody "Concentration" area. Thus, both secondary standard S 1 and S3 apply to <br /> the BRB-2 area. In the evaluation of BRB-2 woody plant Concentration Area density data below, <br /> mandatory standards Pl and P2, Upland Fenced Shrub area secondary standard (SI), and Fenced <br /> Aspen area secondary standard (S3)mentioned above will be addressed. <br /> Table 5. 2015 and 2016 Data and Sample Adequacy Summary for Background and <br /> Concentrated Area Woody Plant Density, Yoast BRB-2 Phase III & Phase II + III Bond <br /> Release Area. <br /> Woody Density Area Woody Density <br /> S N Nmin t <br /> and Sampling Year (stems/acre) <br /> Background Density <br /> BRB-2 Phase III& Phase <br /> 1886.9 59.0 32 117 1.282 <br /> II+ III Bond Release Area <br /> 2015 <br /> Fenced Aspen Woody <br /> 3180.9 57.5 30 40 1.282 <br /> Plant Density BRB-2 <br /> S L-7 - 17 <br />
