Southern Forest Science in Support of a Low Carbon Economy

Guest Editor: Kurt Johnsen

now appearing in Forest Science, October 2012

Articles in this special issue of Forest Science result from a special session held at the 16th Biennial Southern Silviculture Research Conference held in Charleston, South Carolina in February 2011. This session, entitled "Southern Forest Science in Support of a Low Carbon Economy," was organized to address the state-of-science in the forest carbon cycle research, political and technical barriers in developing carbon accounting systems, bioenergy systems, economics of carbon sequestration, and co-benefits and costs as the southern region moves toward a low carbon economy. Articles include: "Carbon Emissions and Sequestration from Fertilization of Pine in the Southeastern United States," "Effect of Harvest Residue Management on Tree Productivity and Carbon Pools during Early Stand Development in a Loblolly Pine Plantation," and "A Comparison of Three Field Sampling Methods to Estimate Soil Carbon Content."

Seven-Year Effects of Midstory Removal on Natural and Underplanted Oak Reproduction

upcoming in the Northern Journal of Applied Forestry, December 2012

Midstory removal can enhance the development of oak advance reproduction on higher quality sites, but the long-term response of oak species common to intermediate quality sites is relatively unknown. The authors investigated the response of natural and underplanted black and white oak and natural red maple reproduction following midstory removals, with adjacent unaltered controls, in four stands on the Northern Cumberland Plateau. They compared survival, size, and competitive position of tagged seedlings seven growing seasons after treatment. Survival, mean height, and mean basal diameter of all species were generally higher following midstory removal. However, red maple and other shade-tolerant species were more abundant than oak seedlings in both treatments. While midstory removal was successful in improving oak development, removal of competitor species like red maple may be necessary to ensure oak recruitment.

Influence of Herbicide Site Preparation on Longleaf Pine Ecosystem Development and Fire Management

upcoming in the Southern Journal of Applied Forestry, November 2012

Herbicide site preparation is common in longleaf pine artificial regeneration to reduce competition and promote seedling establishment. Yet few studies have evaluated longer-term influences of the herbicides on ecosystem development and fire management. The authors evaluated the response of longleaf seedlings, woody stem density, herbaceous vegetation cover, species richness, and fine fuels to two treatments: imazapyr/glyphosate and hexazinone. Six years posttreatment, hardwood stem density was five times higher on control plots; vegetation composition and structure were otherwise similar. Total herbaceous fuels were enhanced by hexazinone in particular, which bodes well for fire management and continued hardwood control. Increased woody litter on control plots modified fuel beds in ways that may inhibit fire management. Results suggest that herbicide-treated plots are better poised for restoration success without additional treatments beyond fire.

Conifer Crown Fuel Modeling: Current Limits and Potential for Improvement

David L.R. Affleck, Christopher R. Keyes, and John M. Goodburn

now appearing in the Western Journal of Applied Forestry, October 2012

The characterization of crown fuel parameters is a critical element in many fire behavior simulators. The authors briefly review the development and limitations of current conifer crown fuel models, then identify and evaluate conifer crown modeling efforts and techniques that have been advanced outside the fire and fuels domain. While the latter models often focus on crown parameters distinct from those traditionally described in fuels studies, the authors contend that advances in conifer crown fuel modeling can be made by extending the results of these parallel lines of research. Such advances are needed to adequately parameterize crown fuels if we are to reap advantages from next-generation fire behavior models. Further, more information must be derived from long-term fuels treatment and silvicultural trials to improve understanding of how conifer crowns respond to treatments.
