<br />METHODS <br />Quantitative Sampling - Geaeral: <br />All methods employed during the 1991 and 1992 studies were repeated in 1993 <br />with the exception that multiple hit cover data was not collected. Methods follow those <br />outlined on page 50 of the 1987 Findings Document. In accordance with the Findings <br />Document, a minimum of 10 cover transects and 25 production plots were collected <br />over the reclaimed surface. Samples were collected until adequacy (with 90% <br />statistical confidence) was reached for both parameters. <br />Sample locations were rerandomized in 1993 and are different from those used <br />in the 1991 and 1992 studies. Sample locations were selected randomly from within <br />the reclaimed surface (50 x 50 foot grid) and were determined th the field through the <br />• use of compass and pacing. The approximate locations of sample points are designated <br />on the enclosed map. Cover transects originated from marked sample locations and <br />five production plots were randomly located along the length of the 25 meter transects. <br />Total Herbaceous Cover: <br />Total herbaceous cover was estimated using an optical point frame developed by <br />ESCO Associates. In accordance with page 50 of the 1987 Findings Document, point <br />sitings were located along a 25 meter transect stretched out either northwest, northeast, <br />southwest, or southeast of the sample location (the direction was randomly selected <br />from among the four possibilities). The 50 points per transect (one point at each half <br />meter interval) comprised a single sample unit. Cover was identified by plant species, <br />or as rock, litter, or bare ground. For the purposes of estimating total herbaceous <br />• cover, only first hit data were collected. <br />2 <br />
