The statistical <br />conclusion is that the Area 2 revegetated areas meet the revegetation success criterion <br />for cover at this time. These areas have live aerial vegetation cover equal to or greater <br />than 9030 of the 22,67% Upland Sagebrush Reference Area aerial vegetation cover <br />with 90% statistical confidence, These areas qualify at this time for Phase II Bond <br />Release based on the vegetation cover criterion. <br />IS <br />
