Radiative Forcing Over The Conterminous United States Due To Contemporary Land Cover Use Change And Sensitivity To Snow And Interannual Albedo Variability, Christoper A. Barnes, David P. Roy
Radiative Forcing Over The Conterminous United States Due To Contemporary Land Cover Use Change And Sensitivity To Snow And Interannual Albedo Variability, Christoper A. Barnes, David P. Roy
GSCE Faculty Publications
Satellite‐derived land cover land use (LCLU), snow and albedo data, and incoming surface solar radiation reanalysis data were used to study the impact of LCLU change from 1973 to 2000 on surface albedo and radiative forcing for 58 ecoregions covering 69% of the conterminous United States. A net positive surface radiative forcing (i.e., warming) of 0.029 Wm−2 due to LCLU albedo change from 1973 to 2000 was estimated. The forcings for individual ecoregions were similar in magnitude to current global forcing estimates, with the most negative forcing (as low as −0.367 Wm−2) due to the transition to forest and the …
Investigating Wood Welding Parameters Using A Prototype Welding Machine, Timothy R. Melin
Investigating Wood Welding Parameters Using A Prototype Welding Machine, Timothy R. Melin
Master's Theses
Understanding how different processing variables influence wood welded bonds is vital if the technique will ever be used to create engineered lumber without using adhesives. A variation of vibration welding, wood welding uses pressure and friction to bond materials together. During welding, heat causes a softening in the wood, a naturally occurring composite material. This softening leads to fiber entanglement and a bond forms upon cooling.
The goal of this research was to investigate several processing aspects of the wood welding procedure. A prototype wood welding machine, designed and fabricated from the ground up, was used to investigate the effects …
Assessment Of Control Charts For Evaluating Dynamic Accuracy Of Forest Growth Models, Richard Raymond Cristan
Assessment Of Control Charts For Evaluating Dynamic Accuracy Of Forest Growth Models, Richard Raymond Cristan
Masters Theses
The purpose of this study was to determine if control charts are an effective tool to identify trends in forest growth and yield model accuracy. Accurate forest growth and yield models are important for projecting future forest composition. However, environmental factors have the potential to make forest growth models created from historic data inaccurate. Control charts in this study determine if forest growth predictions fall within confidence limits established for historic growth at a number of points in time. Two data sets were used in this study: the first was a Continuous Forest Inventory (CFI) from three tracts at the …
Competitive Interactions Between Appalachian Hardwoods And Different Groundcovers On Reclaimed Mine Sites, Adam David Klobucar
Competitive Interactions Between Appalachian Hardwoods And Different Groundcovers On Reclaimed Mine Sites, Adam David Klobucar
Masters Theses
Coal mining is a significant industry in Appalachia. Herbaceous groundcovers are commonly planted to reduce soil erosion and protect water quality during mine reclamation, but many groundcovers may be too competitive to be compatible with trees. The objectives of this research were to investigate the performance of trees planted within different groundcovers and to measure how different groundcovers influence resource availability, specifically soil moisture and light
Two studies were performed; one in a greenhouse and the other on 3 mine sites in east Tennessee where seedlings were planted and grown in competition with different groundcovers. Growth, biomass, leaf area, and …
Successional Vegetation In The Jocassee Gorges, South Carolina, Maxwell Boyle
Successional Vegetation In The Jocassee Gorges, South Carolina, Maxwell Boyle
All Dissertations
Multifactor ecosystem classification systems provide a three-pronged approach to identifying site units across the landscape based on repeating patterns of vegetation, soil, and geomorphology. Ecosystem classification models have been developed for a diversity of forest landscapes throughout North America, and are beneficial as an ecosystem management tool because the outcome yields data models that can be utilized by scientists and natural resource managers alike. In contrast to the enormous amount of classification studies undertaken in relatively stable, older-aged forests in eastern North America, there have been few studies that have employed multifactor classification techniques across a successional gradient, or heavily …
Two-Year Growth And Mortality Of Sub-Canopy Baldcypress (Taxodium Distichum [L.] Rich.) In Artificial Canopy Gaps In A North Carolina Swamp, William Degravelles
Two-Year Growth And Mortality Of Sub-Canopy Baldcypress (Taxodium Distichum [L.] Rich.) In Artificial Canopy Gaps In A North Carolina Swamp, William Degravelles
All Theses
Baldcypress (Taxodium distichum, [L.] Rich.) -tupelo (Nyssa spp.) swamp forests are a major component of the total area of southeastern U.S. forested wetlands which provide valuable ecosystem services related to water quality, stormwater catchment, and wildlife habitat. Historically, baldcypress has also been an important source of wood products, and clearcutting the principal method of harvesting and regenerating the species. However, anthropogenic alterations to flows of many rivers and the associated flood patterns of alluvial wetlands have prevented the establishment of new baldcypress cohorts in many swamps. Regular, extended growing season flooding could prevent germination and/or establishment of baldcypress seedlings if …
Soil Moisture Profiles And Root Growth Of Hardwood Trees Planted In Different Groundcovers On The Steep Slopes Of Reclaimed Mine Sites, Elizabeth Anne Aubuchon
Soil Moisture Profiles And Root Growth Of Hardwood Trees Planted In Different Groundcovers On The Steep Slopes Of Reclaimed Mine Sites, Elizabeth Anne Aubuchon
Masters Theses
Surface mining is a major industry in eastern Tennessee that removes much of the native forest. To restore the forest, reclamation practices are used. These include planting a ground cover species with native hardwoods. Competition between the ground cover and tree species for soil resources could hinder growth and decrease survival of the trees. Northern red oak (Quercus rubra) was used for this study to examine the possible effects of this competition and the relationships between root growth and soil moisture through a field and a greenhouse experiment.
A field experiment was designed using four different ground cover treatments (Soldiago …
Applied Ecosystem Services In Working Forests: A Direct Market Valuation, Darin Stuart Hale
Applied Ecosystem Services In Working Forests: A Direct Market Valuation, Darin Stuart Hale
Masters Theses
Ecosystem services, or the benefits humans obtain from natural ecosystems, have long been recognized as critical to human health. Efforts have been taken by many to determine the non-market values of these services but few have offered a direct market valuation. Increasing awareness, scarcity, and regulation have fostered transactions, and markets are emerging that can allow for direct valuation and could provide landowners the opportunity to merchandise this natural capital. This paper provides a valuation and comparison, as a case study, of a traditional management scheme, including the marketing of fiber and recreational leases, and an ecosystem services management scheme, …
Guide To Woody Plants Of Nebraska, Justin R. Evertson, Kim Todd, David Mooter, Kate Schumacher
Guide To Woody Plants Of Nebraska, Justin R. Evertson, Kim Todd, David Mooter, Kate Schumacher
Nebraska Forest Service: Publications
Species diversity is the cornerstone of a healthy community forest. In an effort to increase species diversity, this publication provides a nearly complete list of woody plants that can be grown in Nebraska communities. Each plant is keyed to the hardiness zone map on this page to show where it will grow best in Nebraska. It should be noted, however, that many plants need extra care and protection to survive certain climates. Conversely, many plants may do well outside of their recommended zone if the proper microclimate exists.
How To Manage Your Woodlands For Sustained And Maximum Benefits, Steven D. Rasmussen
How To Manage Your Woodlands For Sustained And Maximum Benefits, Steven D. Rasmussen
Nebraska Forest Service: Publications
Nebraska's forest lands comprise less than 2 percent of the total land base in the state (7 18,300 acres). However, on an acre by acre comparison, woodlands provide more associated benefits for society, the environment and our quality of life than most other land uses. Trees provide soil protection from wind and water erosion. Woodlands help protect the quality of adjacent water resources by eliminating contaminates, shading for cooler water temperatures and contributing organic matter for use by aquatic life at all levels. Trees and shrubs also trap snow for spring moisture. Woodlands are necessary areas for many wildlife species …

Land Cover Inventory Of The Niobrara River Watershed, Patti R. Dappen, James W. Merchant
Nebraska Forest Service: Publications
The Niobrara River watershed covers a large area in northern Nebraska, and neighboring parts of South Dakota and Wyoming, and is an important component of statewide natural resources management. Under ongoing agreements with the U.S. Bureau of Reclamation (BoR), the Nebraska Game and Parks Commission are charged with the development of management plans for various BoR projects in the Niobrara River watershed in Nebraska. A detailed delineation of land use and land cover patterns was needed in order to define and implement effective management strategies.
