Productivity <br />Only the topsoiled portions of the West Ridge Area and Moffat Area subject to this bond <br />release application have a revegetation productivity standard. There are no productivity <br />standards for the Support Facilities Area or the non - topsoiled portions of the Moffat Area or <br />the West Ridge Area subject to this bond release application. <br />The topsoiled portions of the West Ridge Area subject to this bond release application <br />exceeded the 2005 production standard of 80.20 g /m2 with a mean of 126.5 g /m2 in 2005. <br />The topsoiled portions of the Moffat Area subject to this bond release application exceeded <br />the 2005 production standard of 80.20 g /m2 with a mean of 160.9 g /m2 in 2005. <br />The topsoiled portions of the West Ridge Area subject to this bond release application <br />exceeded the 2006 production standard of 41.60 g /m2 with a mean of 149.6 g /m2 in 2006. <br />The topsoiled portions of the Moffat Area subject to this bond release application exceeded <br />the 2006 production standard of 41.60g /m2 with a mean of 185.2 g /m2 in 2006. Since the <br />reclaimed area production values exceed the reference area success standards, the reclaimed <br />areas satisfy the requirements with respect to production. <br />Diversity <br />Only the topsoiled portions of the West Ridge Area and Moffat Area subject to this bond <br />release application have revegetation diversity standards. There are no diversity standards <br />for the Support Facilities Area or the non - topsoiled portions of the Moffat Area or the West <br />Ridge Area subject to this bond release application. <br />Species diversity success was determined from pre- mining vegetative cover data. The <br />species diversity success standard on topsoiled rangeland areas of the Edna Mine consists of <br />1) The presence of at least five perennial species, with relative importance of each <br />species equal to or greater than 3 %, but less than 40 %. <br />2) The combined relative importance of the five herbaceous species will not exceed <br />75 %. <br />3) If there are six or more perennial, herbaceous species that satisfy the relative <br />importance requirements, then the maximum combined relative importance <br />standard will be waived. (Permit page 4.4 -3) <br />A numerical standard for cool and warm season and forb species is not required, due to <br />planting of a diverse permanent reclamation seed mixture of perennial, predominantly native <br />plants containing cool and warm season grass species and forbs and woody species. (Permit <br />page 4.4 -3) <br />In 2005, there were a total of six perennial species in both the West Ridge bond release area <br />and the Moffat bond release area that met the species diversity standard. In the 2006 <br />sampling, there were seven herbaceous species within the West Ridge area and the Moffat <br />Edna Mine Page 19 April 12, 2013 <br />Phase II. and III Bond Release <br />
