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 estimated <br />teen weights. <br />The ratio between estimated and actual clipped green weights. <br />s Air d weight values were derived from the actual weight of oven-dried clipped samples for each species. <br />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 converts <br />direct) to pounds per acre). <br />2007 Annual Report 25
