<br />Species Diversity: <br />Species diversity will be determined from cover data. <br />During cover sampling, all herbaceous vegetation hits <br />(first, second, third...) will be recorded for use in <br />calculating relative species cover upon which the species <br />diversity standard will be based. <br />Species Lists: <br />Species lists will be compiled for each disturbed <br />community and reference area. Voucher specimens will be <br />collected and confirmed or identified by William Weber, <br />retired Curator of the University of Colorado herbarium. <br />Statistical Evaluation: <br />The calculation of sample adequacy and the disturbed <br />community - reference area comparison of total cover and <br />total herbaceous productivity will follow methods outlined <br />on pages 15 and 16 of the Division's Vegetation Guidelines. <br />
