• Total Herbaceous Production: <br />The 1987 Findings Document indicates that quarter meter square quadrats were <br />to be used in estimating total herbaceous production. At each sample location, five <br />plots (A through E) were placed randomly along the length of a 25 meter transact. <br />Thus plots were located on astratified-random design and each individual production <br />plot was considered to he a single sample unit. All current annual herbaceous <br />production rooted within each quadrat was clipped, separated according to life form, <br />and bagged. The five life forms included perennial and annual grasses, perennial and <br />annual forhs, and noxious weeds. Me/ilolus ofjicutu/is (Yellow swee[clover), which is <br />a biennial, was bagged separately because its life form status was in doubt. <br />Following completion of the field work, all production samples were initially air <br />dried for three weeks or more anJ then oven-dried at 110 degrees Fahrenheit to a <br />• constant weight. <br />Species Diversity: <br />Species diversity was determined from multiple hit cover data. During cover <br />sampling, all herbaceous vegetation hits (first, second, third...) were recorded tier use <br />in calculating relative species cover upon which the species diversity standard was <br />based and was to be ,judged. <br />Species Identification; <br />Voucher specimens were collected and confirmed or identified by Dr. William <br />A. Weher, retired Curator of the University of Colorado herbarium as part of the 1991 <br />study. One specimen was collected in ] 992 for llr. Weber's inspection. Otherwise, all <br />• species that were identified during the 1992 study were the same as those collected in <br />3 <br />
