Although it was not <br />identified as a sample parameter, a brief discussion of species diversity is included. Transect <br />locations for the sampling event conducted on June 27 and 28, 2001, are illustrated in Figure A- <br />l. The aualysis and results of each parameter are contained in the following sections. <br />' <br /> Vegetative Cover - 2001 <br />' Sample adequacy for vegetative cover on the Pasture Reference area was based upon the total <br /> amount of live "hits", and is displayed in Table A-1. <br />t <br /> Table A-1 <br />' Empire Mine <br /> 50-meter Vegetation Cover Point-Intercept Transects <br /> Summary of 2001 Sample Adequacy Calculation <br /> <br /> Mean Absolute Computed <br /> Vegetation Cover Standard Actual Adequate <br />' Area (percent) Deviation Sample Size Sample Size <br /> Pasture Reference Area 18.00 2.42 I S 9.25 <br /> <br />Baseline analysis of vegetative cover is based upon live "hits" on all species. Results from the <br />summer of 2001 sampling event show that mean absolute vegetation cover on the Pasture <br />Reference Area totals 18.0 percent. Sampling revealed that perennial grasses exhibit the greatest <br />' relative cover (82.56 percent), followed by annual fortis and alfalfa, which totaled 10.33 percent <br />and 5.94 percent relative cover, respectively. Table A-2 summarizes the relative cover for each <br />vegetative life-form sampled. Table A-5 displays the results of the 2001 sampling event for <br />' vegetative cover on the Pasture Reference Area. <br />I 1 <br />' 100/ Basefine Vegetation Sn~d/• -Empire Mine/995/October l8, 100/ A-5 <br />
