The only liwitation placed on the quadrant <br />' location will be that no overlap occurs between any of the <br />quadrants. If overlap does occur. then a new location and <br />orientation will be selected in a random manner. <br />' After completing the initial sampling, a mean and <br /> variance will be computed for the parameter and it will be <br />' used in the Snedecor-Cochren equation to determine if an <br /> adequate sample has been taken.

The cover values of each species will be <br />t used to determine what percentage each contributes to the <br /> total herbaceous cover. <br />' A survey to determine whether any rare or endangered <br /> species are present will be conducted,along with the vege- <br />' tation sampling <br /> . <br /> Species Diversity <br /> Species Diversity will be determined using the Shannon- <br />' Weiner Index. The species diversity standard will be set, <br />with approval from the Mined Land Reclamation Division, fol- <br />lowing collection of the baseline vegetation information. As <br />' an example, if 10 species make up 70% of the diversity index, <br />the standard will be for 10 species to make up 70% of the di- <br />versity index. <br /> <br />
