Biomass production was measured using a double sampling procedure of estimates <br />adjusted b actual values from representative samples. Weight units are rams unless otherwise noted. <br />' Three of the ten quadrates were estimated then clipped to derive an actual green weight correction factor used to adjust <br />estimated green weights. <br />2 The ratio between estimated and actual clipped green weights. <br />a Air d weight values were derived from the actual weight of oven-dried clipped samples for each species. <br />4 Species composition values are based upon the percentage of total above ground biomass production for all species. <br />5 Utilizing a NRCS & BLM standard conversion rate of grams to pounds per acre (gram weights from ten 9.6 sq. ft. quadrates <br />converts direct) to pounds per acre). <br />TABLE7 - Reclaimed Well Pad 4-3H Ground Cover <br />September 2007 <br />Cover T pe Percent Cover' <br />Grasses Scientific Name Common Name <br />AGDA A ro ron das stack um Thicks ike Wheat grass 4.5% <br />AGSM Agro ron smithii Western Wheat grass 1.4% <br />BRTE Bromus tectorum Cheat grass 0.3% <br />ELCI El mus cinereus Basin Wild rye 4.6% <br />ELJU El mus 'uncea Russian Wild rye 18.3% <br />ORHY Or opsis h menoides Indian Rice grass 1.4% <br />STCO Sti a comata Needle & Thread Needle grass 1.7% <br /> Total Grasses 32.2% <br />Forbs <br />ASCI Astra a/us cicer Cicer Milkvetch 1.1% <br />CROC Cre is occidentalis Hawksbeard 0.2% <br />LILE Linum lewisii Lewis Flax 0.9% <br />MESA Medics o sativa Alfalfa 1.9% <br />PEPA Penstemon Palmeri Palmer's Penstemon 4.2% <br />SAKA Salsola kali Russian thistle 1.3% <br /> Total Forbs 9.6% <br />Shrubs <br />ATCA Atriplex canescens Four-win Saltbush 17.8% <br />EULA Eurotia Janata Winterfat 1.0% <br /> Total Shrubs 18.8% <br /> Moss/Lichen 0.0% <br /> Vegetative Litter 5.7% <br /> Bare Ground 27.7% <br /> Rock 6.0% <br />TOTAL 100.0% <br />Data was collected September 7 & 8, 2007 utilizing ten 9.6 square foot quadrates.
