Relative cover and relative frequency were summed to obtain an importance <br />value on which all species were serially ranked. <br />' Species Diversity. Information on species diversity was obtained by keeping <br /> track of all the observed species in each of the sampled areas. The mean number of <br /> species per transact was also determined. Sve~'i s that µ~ r obi rvad in each of the - <br />' areas but were not encountered as hits on the transact lures, appear in the cover data <br /> tables as skies with less than, nr,a percent mean cover and zero percent frequency. <br />' Biomass Production. Biomass production data were obtained using a harvest <br /> method. All of the current years growth included within a single ].0 square meter <br /> quadrat was clipped at each of the random biomass sampling sites. Clipped samples <br />' were sorted based on species for grasses and semi-shrubs. Some forbs were clipped on <br /> the basis of species and others were grouped into samples based on life forms. Shrubs, <br /> cushion plants and cacti were not clipped. Clipped samples were placed in paper bags, <br />' then returned to the laboratory, oven-dried and weighed. Preliminary sample <br /> adequacy evaluations were conducted in the field on the basis of fresh weights. Final <br />' sample adequacy determinations were based on dry weights. <br /> Shrub Density. Shrub density data were collected using a line transact <br />' approach. All shrubs occurring within one meter on either side of the 25 meter transact <br /> line (used for collecting cover data) were counted on the basis of species. Shrub density <br /> data were not collected in the reference areas because the determination of revegetation <br />t success for woody plants was based on comparison with an established standard rather <br /> than on the basis of comparison with reference areas. Sample adequacy was obtained <br /> for each of the reclaimed areas. <br />' RESULTS <br />' 1998 Sampling Results <br />1984 Reclaimed Area.
