Sample locations will be determined itt the field by <br />pacing fmm recognizable landmarks. <br />Vegetative Crouud Cover <br />Vegetative ground cover will be evaluated on the two reclaimed areas by utilizing 50-meter point <br />intercept transects. Two sampling points (one meter apart) on both sides of the transect will be <br />sampled at one meter intervals, resulting in 100 sample points per transect. Each corresponding <br />sample point is determined by projection of the ocular sight (Cover-Point Optical Paint Projection <br />Device, Modell)verticallydownwardandphysicallyrecordingallmannerof"first hits". The"first <br />hits" will be recorded as rock, bare ground, litter, or live vegetation. Live vegetation will be Further <br />classified to genus and species. Vegetative ground cover on the two reclaimed areas will be <br />considered successful if the sample mean is at least 90 percent of the cover sample meant measured <br />on the Pasture Reference Area. <br />The live vegetative "first hits" will be used to calculate total vegetative cover for each trattsect <br />according to Equation 1. <br />(~ ) <br />Percent Total Vegetative Cover =Number ujNits on Vegetation <br />Total Number of Points <br />Fifteen transects will be initially evaluated for success comparison and statistical evaluation <br />purposes. The Snedecor-Cochran sample adequacy formula (Equation 2) will be utilized to <br />determine that an adequate number of transects ere sampled. <br />(2) <br />_ t~ sZ <br />N„u~ (d z)z <br />
