We developed a Southern Forest Resource Assessment Consortium (SOFAC) in 1994, which is designed to enhance our capabilities to analyze and model the southern forest and timber resources. Southern growth and yield analyses prepared for the RPA via SOFAC indicate that substantial increases in timber productivity can occur given current technology. A survey(More)
Catastrophic shocks to existing stocks of a renewable resource can cause long-run price shifts. With timber, these long-run price shifts may be accompanied by a short-run price drop due to salvage. Hurricane Hugo damaged 20% of southern pine timber in the South Carolina Coastal Plain in 1989. To estimate the short-and long-run effects of the hurricane on(More)
SUMMARY The southern United States produces over 50% of commercial timber harvests in the US and the demand for southern timber are likely to increase in the future. Global change is altering the physical and chemical environmental which will play a major role in determining future forest stand growth, insect and disease outbreaks, regeneration success, and(More)
Supply chain and delivered cost models for seven feedstocks (loblolly pine, Eucalyptus, natural hardwood, switchgrass, Miscanthus, sweet sorghum, and corn stover) were built, simulating a supply of 453,597 dry tons per year to a biorefinery. Delivered cost of forest-based feedstocks ranged from $69 to $71 per dry ton. On the other hand, delivered cost of(More)
The South can increase forest productivity on industrial and nonin-dustrial private forest (NIPF) lands. As timber markets have improved and timber prices have increased, returns from intensive management are more profitable. The interaction of timber markets, inventory, and prices are analyzed in new southern timber supply models sponsored by the Southern(More)
The future of a wood-based biofuel/bioenergy sector could hold important implications for the use, structure and function of forested landscapes in the South. This paper examines a set of questions regarding the potential effects of biofuel developments both on markets for traditional timber products and on the provision of various non-timber ecosystem(More)

In this article we develop a methodology to test for changes in the underlying relationships between measures of forest productivity (structural elements) and site characteristics, herein referred to as structural changes, using standard forest inventories. Changes in measures of forest growing stock volume and number of trees for both hardwood and softwood(More)
Prior research in 2005 and 2008 estimated planted forest investment returns for a set of countries and included some natural forest species in a few countries. This research has extended those analyses to a larger set of countries and focused on plantation species, for seven years. This research serves as a "benchmarking" exercise that helps identify(More)
