SECTION 4:YEAR 5 TREE MONITORING RESULTS <br /> TABLE 4-1 <br /> Tree Survivorship by Monitoring Year ' <br /> Year 1 (2007) Year 2(2008) Year 3(2009) Year 4(2010) Year 5(2011) <br /> Percent Percent Percent Percent Percent <br /> Planting Site Survivorship Survivorship Survivorship Survivorship Survivorship , <br /> dead in Year 3(2009)resprouted from the rootstock in Year 4(2010),forming new growth.These resprouts were <br /> counted as live trees during Year 4(2010)monitoring, and this resulted in increases in survivorship between <br /> Year 3(2009)and Year 4(2010). _ <br /> In 2011, a fire adjacent to Whiskey Slough Road singed a few trees in planting Area A and Addition to Area A, <br /> but only two trees were recorded as dead during the Year 5(2011)monitoring.The fire also burned the lower <br /> tree branches of a few other trees located next to the road. It is possible that a few of these trees will die over the <br /> next few years,slightly increasing mortality in this area. <br /> TABLE 42 <br /> Health And Vigor By Monitoring Year <br /> Year 1 (2007) Year 2(2008) Year 3(2009) Year 4(2010) Year 5(2011) <br /> Health and Health and Health and Health and Health and <br /> Planting Site Vigor Score Vigor Score Vigor Score Vigor Score Vigor Score <br /> Area A 2.6 2.4 2.5 2.5 2.1 <br /> Addition to Area A 2.2 2.4 2.5 2.3 2.0 <br /> Area AA 2.2 2.2 2.4 2.4 2.3 <br /> Area B 1.8 1.6 2.3 2.4 2.4 <br /> Area C 1.6 1.33 1.9 2.2 1.9 <br /> Area D 1.5 1.43 1.7 1.6 1.7 <br /> Average Health t <br /> and Vigor Score <br /> (All Sites) 1.91 1.9° 2.2` 2.2` 2.1 <br /> NOTES: <br /> 3Subsequent to annual tree monitoring, tree replanting in Areas C and D was performed in late-November 2008. <br /> Survivorship in these areas was assessed in Year 3(2009)and Year 4(2010). <br /> °Due to rounding, scores for both 2007 and 2008 are 1.9.The average health and vigor score in 2007 was 1.94; <br /> the average health and vigor score in 2008 was 1.90. <br /> `Due to rounding,scores for both 2009 and 2010 are 2.2.The average health and vigor score in 2009 was 2.23; <br /> the average health and vigor score in 2010 was 2.22. <br /> Vigor Ranks: <br /> (3)-high vigor score <br /> (2)-medium vigor score <br /> (1)-low vigor score <br /> (0)-tree dead <br /> i <br /> 4-2 SACl420307/113570001(YEAR5-2011 HOLTTREE MONITORING_REPORT-FINAL.DOCXI <br />
