Forests contain a large amount of carbon (C) stored as tree biomass (above and below ground), detritus, and soil organic material. The aboveground tree biomass is the most rapid change component in this forest C pool. Thus, management of forest resources can influence the net C exchange with the atmosphere by changing the amount of C stored, particularly in landscapes dominated by forests, such as in the southeastern United States. Our work focuses on the influence of prescribed burning and thinning on total live aboveground tree (TLAT) biomass in the William B. Bankhead National Forest,...

"Wood is an obvious alternative energy source": Johnson and others (2007) declare the potential of short-rotation intensively-managed woody crop systems to produce biomass for energy. While obvious as an energy source, costs of production need to be measured to assess the economic viability of selected tree species as woody perennial energy crops

Chinese tallow tree [Triadica sebifera (L.) Small, formerly Sapium sebiferum (L.) Roxb.] is a monoecious and deciduous tree, native to central and southern China. As a nonnative invasive tree species, it has aggressively invaded forestlands in southeastern United States, particularly the low- and bottom-land forests along the coastal region of the Gulf of Mexico. This study, on the basis of a destructive sample of 11 tallow trees collected from a bottomland oak-gum-cypress forest in the southern Mississippi, developed a group of individual tree level models to reflect the growth of...

With the increasing interest in short-rotation woody crop (SRWC) systems, an accurate yet quick, non-destructive means for determining aboveground biomass is necessary from both management and research perspectives.

We know that planting trees is a key approach for mitigating climate change; however, we are uncertain of what planting density per unit of land and what cultural regimes are needed to optimize traditional timber products, feedstock, and carbon sequestration.

The Lower Mississippi Alluvial Valley (LMAV) offers an ecological niche for short-rotation woody crop (SRWC) production by mating marginal agricultural land with optimal growing conditions. Approximately 1.7 million ha within the LMAV consist of Sharkey shrink-swell clays. They are considered marginal in terms of traditional agricultural productivity due to their hydric characteristics (Vepraskas and Richardson 1997). However, these soils are ideal for SRWC production using native, welladapted species.

Global energy supply concerns and increasing energy consumption are forcing our society to look into non-fossil-based energy sources and fuels to supplement humanity’s ever growing energy requirements (Hahn 1984, Jenkins and others 2004, Smith 1985, Stortz 1975)

In this study, we examine how family forest owners who receive various types of assistance differ from unassisted landowners with respect to their forestland management practices, attitudes and concerns, and future management, use, and ownership intentions. We do so by utilizing a national database containing information on private forest owners and the forestland they own. By defining an assisted landowner according to several attributes contained in this database (e.g., has a forest management plan, received cost-share assistance, or received advice), important similarities and difference...

Forests in the southeastern United States managed extensively (minimal silvicultural treatments) generally have low productivity rates (Fox and others 2007). Conversely, intensively managed stands have significantly increased productivity in this region, from 2 m3 ha-1 year -1 to a range of 6 to 10 m3 ha-1 year -1 (Fox and others 2007).

Eastern hemlock [Tsuga canadensis (L.) Carr.] is a foundation species that occupies a unique niche in forest ecosystems and which often forms pure stands throughout the eastern United States.
