The two-year old 2006 Reclaimed Area did not meet the <br />production standard due to a large deduction for excess annual species. <br />Woody Plant Density <br />BACKGROUND DENSITY <br />The 2008 data from the 2004 Reclaimed Area indicate the average presence of 611.1 woody <br />plant stems per acre. In 2006 the number for woody plants was only 48.6 stems per acre, and <br />thus a rise of about 12x in woody plant density has occurred from the two-year old stage to the 4- <br />year old stage. This background level easily exceeds the standard of 200 stems per acre. <br />The 2006 Reclamation averaged 498 stems per acre (Table 6) in 2008. This background level <br />easily exceeds the standard of 200 stems per acre. The future is not certain, but with the above- <br />referenced increase from 32 stems per acre in 2005 for the 2003 Reclaimed Area to 797 stems <br />per acre in 2007, it will be interesting to observe how much of an increase, if any, will be <br />observed in 2010. <br />RANDOM SAMPLING OF POTENTIAL BOND RELEASE BLOCK AREA SHRUB DENSITIES <br />• Table 19 contains the data resulting from the sampling of twenty-eight random shrub points <br />placed throughout the Seneca IIW Mine in 2008.
