COMMENTS <br />After four years of sampling, it appears that the revegetation of <br />the mined lands at the site is quite successful. Increases in cover by <br />big sagebrush suggest that over time the reclaimed areas will begin to <br />resemble the surrounding native big sagebrush shrublande. <br />Data from 1991 and 1992 suggest that the reclaimed areas have <br />developed the ability to withstand grazing pressure. The trespass <br />grazing that occurred in 1991 caused the mean cover values to be <br />approximately one-third less in 1991. In 1992, the mean cover values <br />rebounded to Levels that were comparable to those measured in 1990. It <br />ie possible that other factors may have contributed to the lower values <br />in 1991, however most of the differences were likely related to <br />livestock grazing. <br />-5- <br />
