Bioenergy Issues in the Southern United States
Donald L. Grebner, editor
Vol. 35, No. 2 (May 2011)
This special edition was organized in response to the interest bioenergy has generated in forest economics and forestry fields. Articles chosen for this special edition were of particular interest at the 2009 Annual Meeting of the Southern Forest Economics Workers (SOFEW), held at the Carolina Inn in Chapel Hill, North Carolina, March 8-10, 2009; a couple of articles submitted at large were also included. The six articles comprising this issue are:
- Economics of Ethanol Production using Feedstock from Slash Pine (Pinus elliottii) Plantations in the Southern United States" by Tyler S. Nesbit, Janaki R.R. Alavalapati, Puneet Dwivedi, and Marian V. Marinescu, which discusses a cost benefit analysis framework for multiple feedstock levels as well as the cost of cellulosic ethanol production using alternative production technologies.
- Virginia's Woody Biomass Market: Opportunities and Implications by Joseph L. Conrad and M. Chad Bolding, which discusses recent trends in the forest products industry and the wood-to-energy market and potential for competition between the two industries.
- Attitudes toward Policy Instruments Promoting Wood-to-Energy Initiatives in the United States by Francisco X. Aguilar and Adam M. Saunders, which discusses attitudes toward wood-to-energy policy instruments among forest sector stakeholders to identify the most preferred policy tools
- Forest Biomass Supply for Bioenergy Production and Its Impact on Roundwood Markets in Tennessee by Zhimei Guo, Donald G. Hodges, and Robert C. Abt, which discusses the use of the Sub-Regional Timber Supply model to analyze the regional aggregate forest biomass feedstock potential and impacts of additional pulpwood demand on the regional roundwood market through 2030.
- Segmenting Southern Nonindustrial Private Forest Landowners Based on Their Management Objectives and Motivations for Wood-Based Bioenergy by Omkar Joshi and Sayeed R. Mehmood, which discusses a two-step cluster analysis to examine variations in nonindustrial private forest landowners across three states.
- Landowner Willingness to Supply Timber for Biofuel: Results of an Alabama Survey of Family Forest Landowners by Ana Luiza Paula, Conner Bailey, Wayde Morse, and Rebecca J. Barlow, which discusses the conditions under which family forestland owners in Alabama would be willing to supply woody biomass to a prospective local fuel industry.
Human population growth and its subsequent demands on forest resources to sustain itself dictate that the scientific community and practitioners explore all energy alternatives and their potential impacts on our local communities, as well as our state and national economies. One of the exciting aspects of studying bioenergy is the potential triple benefit that it can provide society by revitalizing rural communities, mitigating climate change, and improving domestic energy security. The Southern Journal of Applied Forestry hopes that the enclosed articles in this special edition advance our understanding of the issues surrounding bioenergy and contribute to the development of practical solutions that lead to new markets for this emerging energy resource.
2007 Southern Mensurationists Conference
Mike R. Strub, Chris J. Cieszewski, and Quang V. Cao, editors
Vol. 33, No. 2 (May 2009)
The 2007 Southern Mensurationists Conference was held at the Hilton Garden Inn Beachfront, Orange Beach, Alabama, November 12-15, 2007. About 30 forest biometricians, modelers, and statisticians from Canada, Chile, and the United States participated in the conference. The conference participants presented 30 papers on various topics organized in the following groups: forest biometrics and modeling; inventory and sampling methods; self-referencing functions and parameter estimation methods; wood quality; forest management; and cooperatives and collaboration opportunities.
This special issue of the Southern Journal of Applied Forestry, which includes articles written and revised following the usual peer-review process, was organized to reflect some of the highlights of this conference. The issue contains a collection of seven articles that came from the conference sessions on forest biometrics and modeling (4 articles), inventory (2 articles), and forest management (1 article). The following articles are presented in this issue:
An additional article developed from two presentations at the conference, Evaluation of Four Methods to Estimate Parameters of an Annual Tree Survival and Diameter Growth Model by Quang V. Cao and Mike R. Strub, was published in the December 2008 issue of Forest Science (Cao, Q.V., and M.R. Strub. 2008. Simultaneous estimation of parameters of an annual tree survival and diameter growth model. For. Sci. 54:617- 624).
- Biological, Economic, and Management Implications of Weighted Least Squares, by Curtis L. VanderSchaaf and David South, which discusses impacts of choices between the OLS and WLS parameter estimation in fitting volume equations.
- Calibrating a Segmented Taper Equation with Two Diameter Measurements, by Quang V. Cao, which discusses issues related to fitting tree taper equations using outside-bark and inside-bark diameters.
- A Comparison of Sampling Methods for a Standing Tree Acoustic Device, by Jerry M. Mahon Jr., Lewis Jordan, Laurence R. Schimleck, Alexander Clark III, and Richard F. Daniels, which discusses evaluating potential product performance using acoustic tools for identifying trees with high stiffness.
- A New Whole-Stand Model for Unmanaged Loblolly and Slash Pine Plantations in East Texas, by Dean W. Coble, which discusses development of a new compatible whole-stand growth and yield model for predicting total cubic-foot volume yield (outside and inside-bark) for unmanaged loblolly pine and slash pine plantations in east Texas.
- Does Row Orientation Affect the Growth of Loblolly Pine Plantations, by Ralph L. Amateis, Harold E. Burkhart, and Coleen A. Carlson, which discusses applications of analysis of covariance to long-term loblolly pine spacing trial growth data in studies of row orientation impact on basal area and dominant height growth of loblolly pine.
- Sensitivity Analysis On Long-Term Fiber Supply Simulations In Georgia, by Shangbin Liu, Chris J. Cieszewski, Roger Lowe III, and Michal Zasada, which discusses a spatially-explicit forest management simulations for Georgia sensitivity to management and harvesting assumptions.
- Assessment of Stream Management Zones and Road Beautifying Buffers in Georgia Based on Remote Sensing and Various Ground Inventory Data, by Roger C. Lowe, Chris J. Cieszewski, Shangbin Liu, Qingmin Meng, Jacek P. Siry, Michal Zasada, and Jaroslaw Zawadzki, which discusses spatial assessment and analysis of Stream Management Zones and Road Beautifying Buffers in Georgia.
Silviculture and Genetic Impacts on Productivity of Southern Pine Forests
Steven E. McKeand and H. Lee Allen, editors
Vol. 29, No. 2 (May 2005)
Productivity and value increases in pine plantations in the southern United States have been dramatic over the past 30 years. When the best genetic material is planted and given the necessary resources to grow, mean annual increments of 300 ft3/acre/year can be readily achieved on many sites. There are few other regions in the world where the use of integrated silvicultural systems is having as positive an impact on plantation production. Increases in volume, disease resistance, stem quality, and adaptability have all been impressive, but these gains can only be optimally realized when tree improvement is an integral component of the silvicultural system for managing plantations.
This special issue of Southern Journal of Applied Forestry showcases six articles that summarize presentations from the IEG-40 Genetics and Breeding of Southern Forest Trees meeting, hosted by North Carolina State University in September 2002 at Wrightsville Beach, North Carolina. Articles include:
- What Is Ahead for Intensive Pine Plantation Silviculture in the South?
- Strategies and Case Studies for Incorporating Ecophysiology into Southern Pine Tree Improvement Programs
- Risk Assessment with Current Deployment Strategies for Fusiform Rust-Resistant Loblolly and Slash Pines
- The Future of Tree Improvement in the Southeastern United States: Alternative Visions for the Next Decade
- Planting Nonlocal Seed Sources of Loblolly Pine-Managing Benefits and Risks
- A Review of the Biological, Social, and Regulatory Constraints to Intensive Plantation Culture
