measured using a double sampling procedure of estimates adjusted by actual values from <br />representative samples. Three of the ten quadrates within each reclaimed well pad were <br />estimated then clipped to derive an actual green weight correction factor used to adjust estimated <br />green weights. Clipped samples were oven dried to obtain an air dry weight correction factor for <br />green weights. Ground cover values were made from visual observations of cover type within <br />each quadrate and reported as a percentage of total ground cover. <br />Biomass production, species composition and ground cover data for each site is summarized <br />from the data presented in the appendices for each reclaimed well pad, Table A2 for pad 1 A-41-1I, <br />Table A3 for pad 3A-4H and Table A4 for pad 4-311. The ground cover data in these tables are <br />shown by plant species or cover type. The annual above-ground vegetation biomass production is <br />shown for each plant species encountered at each site. The species composition data is shown for <br />each plant species encountered and determined by each species contribution to total biomass <br />production for that particular site. The scientific and common names of the plant species <br />encountered within each well pad site are also presented in these tables. <br />Well Pad Site 1A-4HI: The ground cover data in Table 4 is summarized by class of vegetation <br />and cover type from data presented by plant species or cover type in Appendix Table A2. The <br />production data presented in Table 5 is summarized from the annual above-ground vegetation <br />biomass production for each plant species as shown in Appendix Table A2. The species <br />composition data presented in Table 6 is summarized by class of vegetation from the percent <br />composition of each plant species encountered as determined by each species contribution to <br />total biomass production as shown in Appendix Table A2. <br />The following tables compare the data collected in 2008 for well pad site 1 A-4HI to data <br />collected from previous years as well as data collected in 2008 from nearby native rangelands. <br />Table 4 - Reclaimed Well Pad 1A-4HI Ground Cover (%), <br />July 2008 <br />Cover Type 2007 2008 2008 Native <br />Ran eland Change <br />2007 to 2008 Difference <br />2008 w/ Native <br />Perennial Grasses 24.5 34.7 27.70 +29% +20% <br />Perennial Forbs 5.3 14.9 6.65 +64% +55% <br />Annual Grasses 1.4 0.0 1.40 - 100 % - 100 % <br />Weed Forbs 14.3 1.0 0.75 -93% +25% <br />Shrubs 9.5 8.7 19.80 -8% -56% <br />Moss/Lichens 0.0 0.0 9.40 no change no change <br />Vegetative Litter 4.0 12.1 13.15 +67% -8% <br />Bare Ground 35.4 22.9 21.15 -35% +80/( <br />Rock 5.6 5.7 0.00 +2% <br />n/a <br />1 <br />2008 Annual Report 17 of 28
