Dry weights were obtained on an Sartorius E8001 P top -loading electronic balance which is <br />accurate to the nearest 0.001 gm. <br />Production sampling methods for the irrigated hayland vegetation type at the New Horizon 2 <br />study area were consistent with those used in 1987. Five hayland fields had been mowed and <br />baled during the study period. These field were all first cuttings. Three fields, belonged to <br />Morgan and two fields belonged to Johnson. All fields were mowed by Morgan and baled using <br />his Heston 4650 Bailer. The bales measured 42 in. X 18 in. X 16 in. Morgan said dry bales <br />consistently weigh between 85 to 90 pounds ever since he obtained the baler. <br />First cutting hay bales were counted either in the field or from the stacks. Next, an adequate <br />sample of the bales from each field was weighed using a Hanson 93490 portable scale. This <br />scale has a maximum capacity of 200 pounds and is accurate to the nearest pound. A <br />minimum of 30 bales were weighed from each field except for one field which had 21 bales. In <br />that field, 10 bales were weighed. Care was taken to select bales from throughout a field, or in <br />cases where the bales had already been stacked, from many locations in the stack. The hay <br />production in the fields, expressed on a dry weight basis as pounds/acre, was calculated by <br />multiplying the total number of bales counted in a field by the average adjusted bale weight and <br />dividing by the size of the field in acres. Additionally, clipped plots in similar irrigated pastures <br />were used for comparison. <br />4.12 Woody Plant Densities - 1999 Woody plant densities were measured in the sagebrush <br />types, dryland pasture reference area, and willow component of the swale/drainage type using <br />belt transects. All trees and shrubs were included in the counts as outlined in CDMG <br />"Guidelines for Compliance with Land Use and Vegetation Requirements for Coal Mining". A <br />species was counted for density if it was rooted within the belt. For all species except willow <br />stems were traced back to their origin and counted as one plant. For example, a sagebrush <br />plant that had 4 stems emanating from a central point was counted as one plant/stem. A 3 ft. x <br />100 ft. belt, originating at the randomly -located sample point and extending in a random <br />direction, was used in the sagebrush type and dry land reference area. A randomly -located 1 <br />square meter sampling frame was used for stem counts in the willow component of the <br />swale/drainage. All willow stems emanating from the ground were counted as it was <br />impossible to determine if any one stem belonged to any one plant. Fifteen samples were <br />collected in this manner. <br />February 2015 (TR -66) 2.04.10-24 <br />
