Comparison of Harvest Scheduling Approaches: Using Woodstock vs. Traditional (Back of the Envelope) Harvest Planning Methods
(2016-03-25)
Understanding and managing agricultural or forestry resources can be very difficult for numerous reasons. Methods used to harvest timber vary, and can affect the NPV of a stand. In this study, we compare two approaches: ...
An Econometric Approach to Applied Microeconomic Theories: The Case of Natural Resource-Based Industries
(2016-04-05)
The forest products industry of Alabama has a dominant role in the state’s economy. The industry has experienced a general downturn in production, employment and number of operating establishments since the mid-1990s. In ...
The Effects of Fertilization and Four Years of Throughfall Reduction on Leaf Physiology of Loblolly Pine (Pinus taeda L.)
(2015-12-10)
Loblolly pine (Pinus taeda L.) is the most widely planted pine species in the southeastern United States. Increased frequency of drought associated with projected climate change may negatively impact loblolly pine productivity. ...
Factors that Affect Fuel Consumption and Harvesting Cost
(2015-05-13)
Fuel consumption in logging is an important component of harvesting costs. There has been an increased interest in the carbon budget associated with timber harvesting as well as an industrial need for updated fuel consumption ...
Global fire activities and their impacts on the terrestrial carbon budget in context of multiple environmental changes
(2015-07-28)
As one major disturbance in the earth system, fires modified vegetation structure and functioning, atmospheric composition, and climate conditions at both regional and global scales. Under the impacts of substantial changes ...
Hazard Exposures for Mechanized Logging Systems in the US South
(2015-08-19)
Logging is a very dangerous occupation with high injury and fatality rates. The logging
industry in the U.S is dynamic and has substantial variability by region. This research focuses on the hazard exposures for mechanized ...
Herbicide Tolerance and Weed Control of Longleaf Pine Native Understory Species
(2015-07-27)
The restoration of longleaf pine (Pinus palustris) is an important environmental issue due to the shrinking size of this once dominant forest type. The restoration of this ecosystem requires the presence of native understory ...
Immigrant Labor in the Forest Industry: The Impacts of H-2B Employment on Local Livelihoods
(2016-05-05)
The production of timber requires labor, with peak labor demands coming during reforestation. Much of the labor used in tree planting in the United States (US) is provided by migrant workers. The overall purpose of this ...
Impacts of Upstream Disturbances on Downstream Sediment Yield and Stream Morphology where Best Management Practices are Present
(2015-11-10)
Attaining high quality water has always been a big concern for humankind. Forested watersheds are known to provide the cleanest form of water. However, conversion of forested lands to agricultural and/or urban use, as well ...
Mapping Stream Channel Head Locations in the State of Alabama
(2015-11-18)
This study focuses on assessing the utility of the slope-area method for predicting channel head locations in forested areas in Alabama under different physiographic regions, improving this method by evaluating the other ...
Microbial Communities in Cogongrass (Imperata cylindrica (L.) Beauv.) Invaded Commercial Loblolly Pine (Pinus taeda L.) Stands
(2015-12-16)
The economy of the southeastern United States is heavily influenced by the forest products industry with a 103 billion dollar industrial output. A significant amount of this industry relies on production forestry to meet ...
Net Exchanges of carbon dioxide, methane, and nitrous oxide between Terrestrial Ecosystems and the Atmosphere in Tropical Asia during 1901–2010
(2015-07-22)
Terrestrial ecosystems act as important sources of the greenhouse gases (GHGs) such as carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O), which cause climate warming. Therefore, understanding and quantification ...
Role of Climate, Land Use/Cover and Water Quality on West Nile Virus Incidence: A Modeling Approach
(2015-07-02)
West Nile virus (WNV), a vector-borne infectious disease, has been a major public health concern in North America since 1999. This virus is transmitted to susceptible mosquitoes when they feed on infected birds. Infected ...
Updating Soil Hydraulic Properties under Changing Land Use/Cover for Improved Hydrologic Predictions
(2015-12-04)
Land use/cover (LULC) change, especially forest to urban transition, can alter the soil hydraulic properties, including soil hydraulic conductivity, even though the soil texture and series may remain the same. Soil hydraulic ...
