New Horizon Mine: 2007 Vegetation Sampling for Phase 2 Bond Release <br />• future. Production measurements and summary statistics are shown in Table A8. Cover and <br />production estimates are summarized and compared in Table 2. <br />Table 2. Comparison of mean cover and production between the Irrigated Pasture reclaimed areas <br />eligible for Phase 2 bond release and the Irrigated Pasture reference area. <br /> Irrigated Pasture Reclaimed Area, <br />Phase 2 Bond Release Irrigated Pasture Reference Area <br /> Mean # of Sam les Mean # of Sam les <br />Cover (%) 85.3 15 68.6 15 <br />Production (Ib/acre) 3,327.0 15 2,512.5 44 <br />Conclusions: <br />Cover. The mean value in the Phase 2 reclaimed areas substantially exceeds the mean in the <br />reference area. No statistical comparison of the mean is possible. However, it appears that <br />cover in the Irrigated Pasture reclaimed areas now eligible for Phase 2 bond release only will <br />exceed the standard (reference area cover) for Phase 3 bond release in the future. <br />Production. The mean value in the Phase 2 reclaimed areas substantially exceeds the mean <br />in the reference area. No statistical comparison of the mean is possible. However, it appears <br />that production in the Irrigated Pasture reclaimed areas now eligible for Phase 2 bond release <br />only will exceed the standard (reference area production) for Phase 3 bond release in the future. <br />• <br />4.0 RESULTS: DRYLAND PASTURE <br />4.1 Drvland Pasture Reference Area <br />Cover measurements for each transect and summary statistics are shown in Table A4. We <br />completed 21 cover transects, and sample adequacy was demonstrated. Production data and <br />summary statistics are sown in Table A10. We sampled 49 plots without reaching sample <br />adequacy, due to the uneven production in the reference area. <br />4.2 Drvland Pasture Phase 2 Bond Release Area <br />Cover measurements for each transect and summary statistics are shown in Table A5. We <br />completed 23 cover transects, and sample adequacy was demonstrated. <br />Although not necessary to demonstrate adequacy for Phase 2 bond release, we measured <br />production in the Phase 2 bond release area, and compared cover and production in the <br />reclaimed area to values in the dryland pasture reference area, to determine the likelihood that <br />current Phase 2-eleigible reclaimed lands would meet Phase 3 revegetation requirements in the <br />future. Production measurements and summary statistics are shown in Table A11. We <br />sampled 31 plots and sample adequacy was demonstrated. Cover and production estimates <br />are summarized and compared in Table 3. <br />• <br />BIO-Logic Environmental 9 <br />November 12, 2007 <br />
