Simulation of hydrologic processes for surface mined lands
Natural factors limit the extent to which land disturbed by man's activities such as the strip mining of coal may be returned to productivity. In the western United States, the availability of water is frequently the most important of these factors. To assist decision makers in land restoration …

Understanding Invasive Species Impacts on Reclaimed Surface-Mined Lands
… main hindrances to the successful reclamation of mined land to restore native forests. In order to better assess the impact autumn olive can have on reclamation success, we characterize autumn olive's performance in various reclamation scenarios and also how the management of autumn olive affects …

Development of Ecosystem Structure and Function on Reforested Surface-Mined Lands
… in the central Appalachian coalfield disturbs landscapes. Post-mining reforestation efforts now achieve successful reestablishment and growth; however, it is unclear whether reforestation efforts also restore the native forest ecosystem functions. We quantified rates of return of key ecosystem …

Soil genesis on relatively young surface mined lands in southern West Virginia
In this study I observed, described and measured differences in morphological, physical and chemical properties as a function of age on mine soils formed from overburden from the New River formation of the Pennsylvanian system in southern West Virginia. Within each group, we sampled nine separate …

Analysis of Reconstructed Mine Soils on Reclaimed Coal and Mineral Sands Mined Lands in Virginia
… without surface amendments. For mineral sands mined lands, I evaluated their spatial variability with respect to underlying relic mining influences and rowcrop productivity. Coal mine subsoils densified as root-limiting layers formed that were not observed initially and all soils had weak …

The Influence of Stand Density on Rate of Carbon Sequestration in Loblolly Pine Plantations on Mined Lands in East Texas
… be obtained through carbon sequestration on NIPF lands or manage reclaimed mined lands for maximum carbon sequestration. This study determined the financially optimal planting density and management regimes for loblolly pine (Pinus taeda) planted on reclaimed mined lands and NIPF lands in East …

Financial Analysis of Restoring Sustainable Forests on Appalachian Mined Lands for Wood Products, Renewable Energy, Carbon Sequestration, and Other Ecosystem Services
… Reclamation Act of 1977 (SMCRA), mandates that mined land be reclaimed in a fashion that renders the land at least as productive after mining as it was before mining. In the central Appalachian region, where prime farmland and economic development opportunities for mined land are scarce, the …

Woody Species Diversity, Forest and Site Productivity, Stumpage Value, and Carbon Sequestration of Forests on Mined Lands Reclaimed Prior to the Passage of the Surface Mining Control and Reclamation Act of 1977
… evidence suggests that many pre-law reforested mined sites are growing productive forests. The purpose of this study was to characterize these forests and the mine soils in which they are growing, and use them to benchmark forest development on mined land. Using 14 mined and 8 non-mined sites in …

Mapping Elaeagnus Umbellata on Coal Surface Mines using Multitemporal Landsat Imagery
… and inhibit efforts to restore disturbed landscapes. Surface coal mines in the Appalachian Mountains are some of the most disturbed landscapes in North America. Moreover, there is not a comprehensive understanding of the land cover characteristics of post- mined lands in Appalachia. Better …

Effects of Silvicultural Treatments and Soil Properties on the Establishment and Productivity of Trees Growing on Mine Soils in the Appalachian Coalfields
… region of the United States, the pre-mining landscape is predominantly forested. Prior to the Surface Mining and Reclamation Act of 1977 (SMCRA), surface mined lands were commonly reclaimed to forests. Subsequent to the passage of SMCRA, reforestation of surface mined lands has decreased. As …

EVALUATING MINE SOIL PREPARED BY SCRAPER PANS FOR HERBACEOUS PLANTS AND PINE SEEDLINGS AT AN EAST TEXAS LIGNITE SURFACE MINE
… of improved reclamation techniques on Luminant’s mined lands have resulted in over 31,160 ha reclaimed to forests, wildlife habitat, and pastures with productivity levels similar to those found on unmined lands. The development of new reclamation methodologies offers opportunities to further …

A computer decision aid for reclaiming eastern abandoned surface mines
… for the reclamation of eastern abandoned surface mined lands. Edaphic, topographic, climatological, and economic factors provide the inputs to the model. By utilizing the present costs and benefits from representative reclamation practices, objective and efficient decisions can be made. The model …

Stochastic dynamic optimization approach for revegetation of reclaimed mine soils under uncertain weather regime
… required to achieve successful revegetation of mined lands at different probability levels of success, subject to an uncertain weather regime. A perennial grass growth model was modified and validated for predicting vegetation growth in reclaimed mine soils. The plant growth model is based on …

Computer aids for reclaiming eastern surface mines as rangelands
… was developed and demonstrated for coal surface mined lands. An objective weighting methodology was employed to determine the optimum forage species mixture to seed surface mined sites. With the optimum mixture determined, total costs for establishment, total monthly available dry matter, and …
