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 />J 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 round biomass production for all species. <br />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 />2007 Annual Report 29
