0.9*[(0.313*SB)+(0.345*MB)= (0.11*AS)+(.128*SMB)+(.104"ASB)] _ <br />0.9[(0.313*19.8)+(0.345'21.2)+(.0.11"31.2)+(0.128*13.3)+(0.104'`16.6)]=18.3 <br />species per 100 sq. m. <br />Mean total species density in 2003 Reclamation = 36.9 <br />Mean total species density in 2005 Reclamation = 26.7 <br />Although these diversity tests are designed to test more mature vegetation that is eligible for bond <br />release and the inevitable presence of ruderal species in young vegetation confuses the matter, <br />comparisons using data from these young areas are of some interest. As of 2007, both the 2003 <br />Reclamation and the 2005 Reclamation well exceed the standard. <br />With regard to Alternative Test C), the similarity index between the lifeform species density values <br />for the prescribed lifeforms for the 2003 Reclamation and the weighted average for the reference <br />areas is 72.8%. Since this value greater than 90% of the standard (0.9 x 70% = 63%), <br />Alternative Test C) is passed for the 2003 Reclamation. For the 2005 Reclamation the Index <br />of Similarity is 69.5%. Since this value greater than 90% of the standard (0.9 x 70% = 63%), <br />Alternative Test C) is passed for the 2005 Reclamation also. <br />With regard to Alternative Test D), the total number of native species encountered in the seven <br />100 sq. m. (2m x 50 m) samples of the 2003 Reclamation was 48, which is greater than the <br />average species density of even the Aspen reference area (38.8 species per 100 sq.m., Table <br />14). Hence, Alternative Test D) is passed for the 2003 Reclamation. For the 2005 <br />Reclamation, the total number of native species encountered in the twelve 100 sq. m. (2m x 50 <br />m) samples was 38, nearly equaling the average species density of the highest component of the <br />reference area (Aspen with 38.8 species per 100 sq.m., Table 14). Hence Alternative Test D) is <br />nearly passed for the 2005 Reclamation. <br />In summary for the 2003 Reclamation, Mandatory Test A) was passed as were Alternative Tests <br />B), C), and D) and hence the species diversity test as a whole is passed for that area of four-year <br />old reclamation. For the 2005 Reclamation, Mandatory Test A) was passed as were Alternative <br />Tests B) and C). Test D) was barely failed, but inasmuch as the permit requirement would <br />necessitate passing A) plus two of the other three, the 2005 Reclamation also as a whole passes <br />the species diversity test. <br />Sample Adequacy <br />A summary of sample adequacy calculations for the parameters of cover, herbaceous production, <br />and woody plant density is presented in Table 16 (Appendix 1).
