Efficacy Of Herbivore Exclusion On Planted Tree Seedling Vitality On A Reclaimed Surface Mine In Eastern Kentucky, Zachary J. Hackworth
Efficacy Of Herbivore Exclusion On Planted Tree Seedling Vitality On A Reclaimed Surface Mine In Eastern Kentucky, Zachary J. Hackworth
Theses and Dissertations--Forestry and Natural Resources
Conventional Appalachian surface-mine reclamation techniques repress natural forest regeneration, and tree plantings are often necessary for reforestation. Reclaimed Appalachian surface mines harbor a suite of mammal herbivores that forage on recently planted seedlings. Anecdotal reports across Appalachia have implicated herbivory in the hindrance and failure of reforestation efforts, yet empirical evaluation of herbivory impacts on planted seedling vitality in this region remains relatively uninitiated. First growing-season survival, height growth, and mammal herbivory damage of black locust (Robinia pseudoacacia L.), shortleaf pine (Pinus echinata Mill.), and white oak (Quercus alba L.) are presented in response to varying intensities …

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 …
