Table G-4.Species Diversity Test D-Phase II Bond Release Blocks 2a and 3,Yoast Mine,SPL,Routt Co.,CO-2016 Page 1 of 1 <br /> BRB-2a 2016 Alternative Test D): Native Species Presence Assessment PASS? <br /> Total cumulative#of native species > or= avg ref area native species density (#species/100 sq.m.) YES <br /> The weighted average species density of native species per 100 sq.m. from the four extended reference areas is 23.3. The cumulative number of native species in the <br /> first 20 100 sq.m. samples of the Phase 11 bond release block that constitute an adequate sample (based on total cover) is 51, (and 46 in the first 15 100 sq.m. samples,- <br /> based on species density), both exceeding 23.3 and indicating a PASS on this test. <br /> Cumulative Number of NATIVE Species in the Cumulative Number of NATIVE Species in the <br /> Area minimum adequate number of samples (i.e. 20, minimum adequate number of samples (i.e. 15, based <br /> based on total cover) minus noxious weeds on species diversity) minus noxious weeds <br /> Yoast Phase II Bond Release Block 2a 51.0 46.0 <br /> 2016 <br /> Average Reference area native species density (#species/100 sq.m.) minus noxious weeds <br /> Aspen Reference Area 28.10 <br /> Mtn.
