Abstract Re-vegetation of mined lands in North Dakota is challenging because of poor physical and chemical properties of the spoil material and a semi-arid climate. Adequate topsoil and subsoil replacement has been a successful method rised to establish productive reclaimed plant communities. Previous studies conducted by Merrill eta/. (1998) and Power eta/.(1 81) have determined adequate soil depth for optimal productivity during six years of study. This was determined through the establishment of topsoil wedges in Zap and Stanton, ND. There-sampling of these sites in 2003 provided important information concerning the long-term effects of soil depth and soil characteristics on plant community development. The influence of total soil depth and soil characteristics was significantly different in 2003 when compared to previous years. In 2003, the highest production on the Zap, ND Double Topsoil Wedge occurred on 40 to 120 em of total soil and the highest diversity was on the alfalfa vegetation strips with 0 to 40 em of total soil. In the previous study, higher yields were on 51 to 110 em of total soil. The highest production on the Stanton, ND Topsoil Wedge was on 65 to 120 em of total soil in 2003. In the previous study, the highest yields were on 92 to 132 em of total soil.
