Establishment Of American Chestnuts On Surface Mined Lands In Appalachian Coalfields Region, Michael E. French
Theses and Dissertations--Forestry and Natural Resources
American chestnut (Castanea dentata (Marsh.) Borkh.) was an dominant hardwood throughout eastern North America until the introduction of an exotic fungus (Cryphonectria parasitica (Murr.) Barr) in the early 20th century devastated American chestnut populations. Chestnuts that have been bred for blight resistance have recently become available for testing. Due to the overlap of American chestnut’s natural range and the Appalachian coalfields region, the potential establishment of founder populations of blight-resistant chestnuts on reclaimed coal surface mines has recently gained attention. This work examined chestnut establishment on a surface mine in eastern Kentucky to assess factors controlling early …

Influence Of Spoil Type On Afforestation Success And Hydrochemical Function On A Surface Coal Mine In Eastern Kentucky, Kenton L. Sena
Theses and Dissertations--Forestry and Natural Resources
Surface coal mining in Appalachia has contributed to a suite of ecological impacts, both terrestrial and aquatic. Conventional reclamation in Appalachia leads to the development of hay/pasture systems dominated by nonnative grasses and legumes, with soils that are chemically and physically unfavorable to native tree growth. Several studies have shown that more weathered minespoils provide a better growth medium than unweathered spoils in Appalachia. Spoil segregation plots were constructed on Bent Mountain in Pike County, KY, to compare the suitability of three mine spoil types (BROWN weathered sandstone, GRAY unweathered sandstone, and MIXED sandstones and shales). In 2013 (after nine …
