Seneca Coal Company <br />Phase II Bond Release Request <br />Alternative Test C for diversity is a similarity index evaluation. The basis for comparing the <br />similarity index (see Seneca II approved permit) for parcels BRB-2, BRB-3, and BRB-4 is as <br />follows. <br />The similarity index for life form species density values for BRB-2 to the mountain brush <br />reference area is: <br /> Species Density/100m2 <br />Life Form BRB-2 MB Ave <br />Annual/Biennial Forbs 6.2 4.0 <br />r'innual Grasses 0.5 0? <br />Perennial Forbs 6.4 1 G.0 <br />Perennial Cool Season Grasses 3.8 6.6 <br />ISmoMB=((4.0+0.2+6.4+3.8)2)/(6.2+4.0+0.5+0.2+6.4+16.0+3.8+6.6)= <br />65.9% <br />May2008 <br />The similarity index for life form species density values for BRB-2 to the sagebrush reference <br />area is: <br /> Species Density/100mZ <br />Life Form BRB-2 SB Ave <br />Annual/Biennial Forbs 62 3.1 <br />Annual Grasses 0.5 0.0 <br />Perennial Forbs 6.4 14.7 <br />Perennial Cool Season Grasses 3.8 8.3 <br />ISmoMB=((3.1+0.0+6.4+3.8)2)/(6.2+3.1+0.5+0.0+6.4+14.7+3.8+8.3)= <br />61.9% <br />The weighted average similarity for the reference areas to BRB-2 is: <br />61.9% x 0.17 + 65.9% X 0.83 = G5.2 <br />11 <br />
