• INTRODUCTION <br />Quantitative sampling of reclaimed areas an Peabody Coal Company's Seneca II Mine was undertaken <br />in July 1991 by ESCO Associates to facilitate Peabody's continuing monitoring of the progress of <br />these areas in relation to revegetation performance standards. Methods, sample areas, and sample <br />sizes were those specified by Peabody. <br />METHODS <br />Reclamation Units and Samolina Locations <br />Reclamation sampling units are shown on Map 1, '1991 Revegetation Monitoring and Sampling <br />Map'. The 1991 reclamation units include: Wadge mining areas reclaimed in 1984; Wadge mining <br />areas reclaimed in 1987; Wadge mining areas reclaimed in 1989; Wolt Creek mining areas <br />reclaimed in 1984; Wolf Creek mining areas reclaimed in 1987; Wolf Creek mining areas <br />reclaimed in 1989; as well as the Wadge Pasture Area reclaimed between 1978 and 1985. In <br />addition to sampling of the above reclaimed units, two small shrub planting areas were intensively <br />. sampled for woody plants. These areas are identified on Map 1 as Shrub Density Area No. 1 (1989 <br />Wadge Reclamation) and Shrub Density Area No. 2 (1986 Wadge Reclamation ). Also, the Seneca II <br />Mine Mountain Brush and Sagebrush Reference Areas were sampled. <br />Within each reclamation unit identified in the Peabody Scope of Work, the Peabody-specified number <br />of samples were located randomly using numbered grid cells and random numbers taken from a <br />random numbers table. The numbered grid cells were placed on a 1 inch = 400 feet scale aerial <br />photograph showing reclamation areas to be sampled. Each random number indicated a grid cell in <br />the middle of which a sample point was placed on the map. These sample points were located as <br />closely as possible in the field. Final location of production quadrats was accomplished by a blind <br />throw; cover and density sample transacts were located and oriented using a blind throw of a <br />meter stick. <br />Cover Samolina <br />Cover data were collected using a point intercept method in which data are tabulated as <br />interceptions of a point with plant species, soil, litter, or rock. The point was optically projected <br />using aCover-point Model 3, developed by ESCO Associates, Inc. The sample, taken at a randomly <br /> <br />• <br />
