Mean Reference Area Species Density — 1.15 s = 38.05 — 1.15 (8.14) = 28.69 <br />Mean total species density in the 2011 BRB PSCM -1 = 18.20 <br />Mean total species density is less than the standard. <br />Hence Alternative Test B is NOT passed for 2011 data. <br />Regarding Alternative Test C, the similarity index between the lifeform species density values for the <br />prescribed lifeforms for 2011 BRB PSCM -1 and the Mean Species density (Area- weighted) in the two <br />reference areas is 77.9 percent (Table H -7), exceeding 90% of the standard (0.9 x 70% = 63 %). <br />Hence Alternative Test C is passed for 2011 data. <br />Regards Alternative Test D, the total number of native species encountered in the first thirteen 100 sq. m. <br />(2m x 50 m) samples of 2011 BRB PSCM -1 that constituted an adequate cover sample was 35, greater <br />than the weighted reference area average species density (34.1 species per 100 sq.m.). <br />Hence Alternative Test D is passed for 2011 data. <br />In summary, Mandatory Test A was passed as were Alternative Tests C and D and hence the species <br />diversity test as a whole is passed for 2011 BRB PSCM -1. <br />29 <br />
