Water quality hydrology on surface mined watersheds
… 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 average annual TDS concentration …

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 …

Survival and growth of pine seedlings on strip-mined sites
… nutrient for pine seedlings on these strip-mined sites.

Nutritional status of beef cows grazing reclaimed strip mined pastures
… status of beef cows grazing reclaimed strip-mined pastures in southwestern, Virginia. Blood samples, esophageal fistula forage samples and hand plucked forage samples were taken in each trial. An external marker, Ytterbium, and an internal marker, indigestible neutral detergent fiber (INDF) …

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 …

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 …

Development of Ecosystem Structure and Function on Reforested Surface-Mined Lands
… of four reforested mine sites and an unmined reference stand were studied in southwestern Virginia. Total soil nitrogen (N) and component (mineral soil, forest floor, root, and aboveground biomass) ecosystem carbon (C) pools were quantified. Throughout the growing season, soil gas fluxes …

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, …

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 …

Developing manufactured soils for reclamation of mined land in the boreal forest ecosystem
The purpose of this study was to manufacture a cover 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 …

Evaluation of Topsoil Substitutes for Restoration of Appalachian Hardwoods on Strip Mined Land
… than the native soils, and because the mined sites do not provide the same level of ecosystem services. This research addressed constraints to the return of the native ecosystem by assessing how mine spoil properties and treatments affect native tree species and soil microorganisms. A …

An Ecological Assessment of Restoration Efforts Developed to Recover an Intensively Mined Appalachian Watershed
… for adaptive watershed management developed for mined watersheds can also be applied to other anthropogenic impacted watersheds in this region. Applying an experimental approach towards restoration project assessments can facilitate restorationists and project managers to understand what types of …

Ecological Benefits of Mitigation on a Large River Mainstem in an Intensively Mined Appalachian Watershed
<p>Large scale surface mining in the central Appalachians causes significant alteration of headwater catchments, and these impacts may be offset through implementation of stream restoration projects. As an example, several habitat enhancement structures (cross-vanes and j-hooks) were constructed …
