Effects Of Excessive Nitrogen Deposition On Foliar Nutrient Dynamics, Nutrient Concentrations, And Nutrient Ratios In A Central Appalachian Hardwood Forest, Sarah Beth Burdette
Effects Of Excessive Nitrogen Deposition On Foliar Nutrient Dynamics, Nutrient Concentrations, And Nutrient Ratios In A Central Appalachian Hardwood Forest, Sarah Beth Burdette
Theses, Dissertations and Capstones
Many forested systems of the eastern US are becoming significantly nitrogen (N) saturated due to chronic N deposition from the atmosphere. Nitrogen saturation has the potential to alter important internal plant processes, such as nutrient cycling. While extensive research has been conducted on the responses of soil to N saturation, considerably less research has focused on the response of plant nutrient dynamics, nutrient concentrations, and nutrient ratios to excess N. Research was conducted on two watersheds at the Fernow Experimental Forest in West Virginia: WS3 (fertilized with ammonium sulfate annually since 1989) and WS7 (untreated control). Presenescent and senesced leaves …
A Gis Approach For The Abandoned Mine Inventory With Haul Roads Of The Monongahela National Forest To Provide A Comparative Analysis Of Usfs/Usace Collection Procedures And Image Basemap Selection For Cartographic Representation, John R. Ferguson Ii
Theses, Dissertations and Capstones
The Monongahela National Forest spans 10 counties in eastern central West Virginia. It has been an area of high mining and timbering activities throughout much of the early to mid twentieth century. As a result, the United States Forest Service (USFS) has focused reclamation and remediation efforts on the abandoned mine land areas. Much of the area has been subjected to mining after effects such as acid mine drainage, structural remains, gob/spoil piles, garbage piles, mine portals, and highwalls. In 1998 the USFS contracted with the U.S. Army Corps of Engineers (USACE) to locate these mining remains and provide a …
Effects Of Harvesting On Herbaceous Layer Diversity Of A Central Appalachian Hardwood Forest, Frank S. Gilliam
Effects Of Harvesting On Herbaceous Layer Diversity Of A Central Appalachian Hardwood Forest, Frank S. Gilliam
Biological Sciences Faculty Research
Clearcutting is a common harvesting practice in many eastern hardwood forests. Among the vegetation strata of these forests, the herbaceous layer is potentially the most sensitive in its response to harvest-mediated disturbances and has the highest species diversity. Thus, it is important to understand the response of herbaceous layer diversity to forest harvesting. Previous work on clearcut and mature stands at the Fernow Experimental Forest (FEF), West Virginia, has shown that, although, harvesting did not alter appreciably herbaceous layer cover, it influenced the relationship of cover to biotic and abiotic factors, such as tree density and soil nutrients, respectively. The …
