Managing symbiotically-fixed nitrogen on mined land for tree crops
… studies containing legume ground covers was examined. The first study site was mined prior to 1940 and subsequently abandoned. In 1988, the land was reclaimed, and an interplanting study was established in 1990. Pitch x loblolly pines (Pinus x rigitaeda) and eastern white pines (Pinus strobus …

On-site wastewater treatment and disposal systems on reclaimed mined land
… disposal facilities. New technologies to reclaim mined lands have the capacity to produce large level expanses of land suitable for building sites by using the minespoil to reshape the land contours. Because these areas are generally too remote for centralized sewer to be economically feasible, …

Developing manufactured soils for reclamation of mined land in the boreal forest ecosystem
… soil that will be suitable to create ‘cover islands’ of native boreal vegetation for reclamation of large mine rock piles generated through open-pit mining activities in the Boreal Shield region north of Lake Superior. Multiple Technosols were manufactured from blends of mill derived organic …

Evaluation of Topsoil Substitutes for Restoration of Appalachian Hardwoods on Strip Mined Land
… reclamation in Appalachia involves returning the land to approximate original contour by grading the surface and planting grasses and early-successional trees. This results in a greatly altered ecosystem compared to the native forest that was there prior to mining. The reclaimed land is usually …

Transformation of Carbon, Nitrogen and Phosphorus in Deep Row Biosolids Incorporation-Hybrid Poplar Plantation in Coastal Plain Mined Land Reclamation Sites
… especially appropriate for reclaiming disturbed land because of the extremely high application rates used. Nutrient additions in excess of the vegetation requirements, especially in coarse-textured soils, can potentially impair water quality. Increasing C and N additions with biosolids DRI can …

Biogeochemistry of Carbon on Disturbed Forest Landscapes
… carbon sequestration potential of surface coal-mined lands is not well known. The purpose of this work was to determine how to measure carbon sequestration and estimate the additional amount that could be sequestered using different reforestation methods compared to the common practice of …

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
The present state of forestry post mining land uses has prompted concern among researchers, landowners, and the public. Surface mines reclaimed to forests under the provision of the Surface Mining Control and Reclamation Act (SMCRA) may not achieve site productivity levels required by the law. …

Reclamation of surface-mined forest land in the southern Appalachians
Most of the surface-mined land in the southern Appalachian coal fields of Virginia, southern West Virginia, and eastern Kentucky is forested before mining. For a variety of reasons, most surface-mined land will ultimately return to forest, either by design or through natural succession. The …

Soil productivity model to assess forest site quality on reclaimed surface mines
… of 1977 requires that mine operators reclaim mined land to achieve productivity levels equal to or greater than premined conditions. Presently, the standard for evaluating reforestation success is based solely on tree-seedling survival. This method is an estimator of stand density and not an …

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 …

Reclaiming the Appalachian Landscape: Understanding Surface Mine Reclamation Through Remote Sensing
Surface mining has been the dominant driver of land cover change in the Central Appalachian region for decades, fundamentally altering the topography and ecological trajectory of over one million acres of forest. While the Surface Mining Control and Reclamation Act (SMCRA) of 1977 mandated the …

Effects of calcium, sulphur and potassium concentration in overburden on quality of strip mine drainage
Planned strip-mined land reclamation that minimizes damage of the environment is vital for preservation of water quality, especially with present increased emphasis on coal production. Analysis of overburden is becoming mandatory in order to plan effective placement of material in spoil piles. One …

Understanding Invasive Species Impacts on Reclaimed Surface-Mined Lands
… back to native forests or other productive land uses. These areas are left fragmented, heavily modified, unmanaged, and densely invaded by non-native plants. Autumn olive (Elaeagnus umbellata) is one of the most prevalent invasive species on reclaimed mines in Appalachia and viewed as one of …

The status and seasonal dynamics of fish and benthic invertebrate populations in relation to organic and inorganic material inputs and surface mining impacts in three Virginia headwater streams
… the watersheds three to five years earlier. The mined-watershed streams carried a heavy benthic sediment burden, due primarily to the continued erosion from the mined areas and from abandoned haul roads. Inorganic sediment in the mining-impacted streams covered the natural rubble substrate, …

Evaluation of reclaimed coal-mined prime farmland based on soil characteristics in lieu of the current yield-based approach
… in 1977, reclamation success of prime farmland after coal mining has been determined by long-term crop yield testing. States such as Illinois and Indiana require that reclamation success be based on crop production of mined-land. This process often can continue for many years, especially …

Water quality hydrology on surface mined watersheds
… from several meters or less on undisturbed land to about 20 meters on mined land. Data show that the disturbed geologic material in the spoils contains large quantities of soluble salts. A single-equation model based upon water and mass balances has been developed which can predict the …

Integrative Bioassessment of Acid Mine Drainage Impacts on the Upper Powell River Watershed, Southwestern Virginia
… environmental problem associated with abandoned mined lands (AML). Numerous studies have documented the impacts of AMD upon aquatic communities within acidified stream reaches; these impacts include reduced taxonomic richness and abundance, and/or a shift from pollution sensitive to pollution …

An Ecotoxicological Assessment of a Treated Coal-mining Effluent in the Leading Creek Watershed, Meigs County, Ohio
… on freshwater systems has focused on abandoned-mined land, and the associated acid drainage and metals toxicity. Treated discharges from active mining and preparation facilities, however, can also impair lotic ecosystems through total dissolved solids (TDS) toxicity, caused primarily by the …

Organic amendment effects on carbon and nitrogen mineralization in an Appalachian minesoil
… as a topsoil substitute during surface-mined land reclamation is practiced in areas with thin, unrecoverable topsoil. The long-term productivity of topsoil substitutes has often been difficult to maintain under forage and row crops. The objective of this project was to evaluate the …

Costs of Reclamation on Southern Appalachian Coal Mines: A cost-effectiveness analysis for reforestation versus hayland/pasture reclamation
The two most common options for post-mining land uses in the southern Appalachians are forestry or hayland/pasture. Hayland/pasture has become the predominant reclamation type due to ease of establishment and strict regulation standards requiring quick and dense erosion control by herbaceous cover. …
