' Ayyertdi~ A - VeRem(ion Sampling for / 998 <br />METHODS <br />' Vegetative sampling was conducted on June 18, 19,and 20, 1998. The reclaimed area and the <br />reference area were sampled separately. The reclaimed area was sampled again on September 16, <br />1998. Sampling was conducted for cover, species diversity and production. Transect locations <br />for all areas sampled are provided on Figures A-1, A-2 and A-3. <br />' Vegetative cover was sampled using 25-meter point-intercept transects that were randomly located <br />and oriented within each sampling area. Transect locations or orientations that resulted in overlap <br />' of previous transects or the sampling area boundary were randomly redirected prior to the point <br />of overlap. Sample locations were determined by overlaying a grid over a map of the sample <br />areas, generating a random number table for X and Y values, and plotting them onto the map. <br />The distance and bearing from known reference points, such as trees or fence corners, were then <br />measured on the map and paced-off while following a compass. At each transect location a 25- <br />meter tape was oriented by multiplying a randomly generated number, having limits of 0 and 1, <br />' by 360 degrees. Two sampling points, one meter apart, on both sides of the transect were sampled <br />at one meter intervals, resulting in 50 sample points per transect. Each corresponding sample <br />' point was determined by projection of the ocular sight (Cover-Point Optical Point Projection <br />Device, Model 2) vertically downward and physically recording all manner of "first hits". The <br />"first-hits" were recorded as rock, bare ground, litter, or live vegetation. Live vegetation was <br />' further classified to genus and species. <br />The live vegetative "first-hits" were used to calculate total vegetative cover for each transect <br />' according to Equation 1. <br />(1) <br />' % Total Veg. Cover No. Hits on Vegetation x 100 <br />Total No. of Points <br />' Mean vegetative cover for each area was the mean value for all transects in that area. <br />The diversity of plant species in each area was evaluated using data acquired from the point- <br />intercept transects. Data from the transects was used to determine the relative cover of each <br />' species detected (Equation 2). <br />(2) <br />Relative Cover of Specles X = % Cover of Species X <br />Total Veg. Cover <br />Percent total vegetative cover for species in each area was the mean of all transects. <br /> <br />Borb057 1999-05J. wpC\Fcbruary 26,1999 <br />A-1 <br />1 <br />
