• INTRODUCTION <br />Quantitative sampling of reclaimed areas on the Peabody Western Coal Company (PWCC) Seneca <br />II Mine was undertaken in July 1992 by ESCO Associates to facilitate Peabody's continuing <br />monitoring of the progress of these areas in relation to revegetation performance standards. <br />Methods, sample areas, and sample sizes were those specified by Peabody. <br />METHODS <br />Reclamation Units and Sampling Locations <br />Reclamation sampling units are shown on Map 1, "1992 Revegetation Monitoring and Sampling <br />Map'. The 1992 reclamation units include: Wadge mining areas reclaimed in 1985; Wadge <br />mining areas reclaimed in 1988; Wadge mining areas reclaimed in 1990; Wolt Creek mining <br />areas reclaimed in 1985; Wolf Creek mining areas reclaimed in 1988; Wolf Creek mining <br />areas reclaimed in 1990; as well as the Wadge Pasture Area reclaimed between 1978 and 1985 <br />and grazed from 1988 to the present, and the Wadge Pasture 1991 Area, likewise reclaimed <br />between 1978 and 1985, but ungrazed until 1991. The Seneca II Mountain Brush and <br />• Sagebrush Reference Areas were also sampled. <br />In addition to sampling of the above reclaimed units, thirteen small shrub planting areas were <br />intensively sampled for survivpl of woody plantings. These areas are identified on Map 1 as <br />Shrub Density Area No. 1 (1989 Wadge Reclamation), Shrub Density Area No. 2 (1986 Wadge <br />Reclamation ), Shrub Density Area No. 3 (1989 Wadge Reclamation), Shrub Density Area No. 4 <br />(1989 Wadge Reclamation), Shrub Density Area No. 5 (1989 Wadge Reclamation), Shrub <br />Density Area No. 6 (1989 Wadge Reclamation), Shrub Density Area No. 7 (1986 Wadge <br />Reclamation ), Shrub Density Area No. a (1989 Wadge Reclamation), Shrub Density Area No. 9 <br />(1989 Wadge Reclamation), Shrub Density Area No. 10 (1989 Wadge Reclamation), Shrub <br />Density Area No. 11 (1989 Wadge Reclamation), Shrub Density Area No. 12 (1989 Wadge <br />Reclamation), and Shrub Density Area No. 13 (1989 Wadge Reclamation). Within these areas, <br />the shrub density samples were 2 m x 15 m in size and were located systematically within the <br />shrub planting areas. <br />t <br />
